spring+springmvc+ibatis整合注解方式实例(附带数据库)

1.需求说明

实现用户通过数据库验证登录需求，采用Myeclipse+Tomcat 6.0+Mysql 5.0+JDK 1.6

2.数据库表

开发所用是Mysql数据库,只建立单张用户表T_USER,表结构如下：

   

字段名称数据类型字段描述IDint用户编号USERNAMEVARCHAR用户名PASSWORDVARCHAR用户登录密码sql语句如下：   

    CREATE TABLE `t_user` (
    `ID` int(11) NOT NULL auto_increment,
    `USERNAME` varchar(255) default NULL,
    `PASSWORD` varchar(255) default NULL,
    PRIMARY KEY  (`ID`)
    );

3.构建源代码目录

4.用到的jar包(见附件Archive.rar)

5.各项Xml配置文件详解

(1)web.xml文件(Tomcat使用)

服务器根据配置内容初始化spring框架，springmvc框架和log4j日志框架    

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">    <!-- 应用程序名称 -->  <display-name>ISS</display-name>    <!-- 应用程序描述说明性文字 -->  <description>Spring,SpringMvc,Ibatis</description>    <!-- ServletContext初始化参数 -->  <context-param>    <param-name>webAppRootKey</param-name>    <param-value>spring_springmvc_ibatis.root</param-value>  </context-param>  <context-param><param-name>log4jConfigLocation</param-name><param-value>/WEB-INF/classes/log4j.properties</param-value>  </context-param>  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>/WEB-INF/classes/applicationContext.xml</param-value>  </context-param>  <!-- 字符过滤,防止添加到数据库的数据为乱码 -->  <filter>    <filter-name>characterEncodingFilter</filter-name>    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>    <init-param>      <param-name>encoding</param-name>      <param-value>UTF-8</param-value>    </init-param>    <init-param>      <param-name>forceEncoding</param-name>      <param-value>true</param-value>    </init-param>  </filter>  <filter-mapping>    <filter-name>characterEncodingFilter</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>    <!-- web权限配置 -->  <filter><filter-name>springSecurityFilterChain</filter-name><filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>  </filter>  <filter-mapping>    <filter-name>springSecurityFilterChain</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>    <!-- 配置监听器,用于初始化 -->  <listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>  </listener>  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <!-- Servlet初始化参数,配置springmvc模块 -->  <servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>/WEB-INF/classes/springmvc-servlet.xml</param-value>    </init-param>    <load-on-startup>2</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>    <!-- 配置session存在时间 -->  <session-config>    <session-timeout>60</session-timeout>  </session-config>    <!-- 默认起始页面 -->  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>    <!-- 异常跳转页面 -->  <error-page><exception-type>java.lang.Exception</exception-type><location>/WEB-INF/jsp/exception.jsp</location>  </error-page></web-app>

(2)springmvc-servlet.xml(Springmvc框架配置文件)

该文件是springmvc框架配置文件，也是它的核心文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:mvc="http://www.springframework.org/schema/mvc"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="        http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd        http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <!-- 自动扫描,完成bean创建和依赖注入 -->  <context:component-scan base-package="com.archie"/>    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>    <!-- 视图解析器 -->  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>    <property name="prefix" value="/WEB-INF/views/"/>    <property name="suffix" value=".jsp"/>  </bean>    <!-- 异常解析器 -->  <bean id="simpleMappingExceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">    <property name="exceptionMappings">      <props>        <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">common/fileerror</prop>      </props>    </property>  </bean></beans>

(4)jdbc.properties(数据源属性文件)

数据源连接信息的源出处，目前配置了三种数据库Oracle，DB2和Mysql

# Database Connectivity# Oracle#driver = oracle.jdbc.driver.OracleDriver#url = jdbc:oracle:thin:@localhost:1521:oracl#username = scott#password = tiger# DB2#driver = com.ibm.db2.jcc.DB2Driver#url = jdbc:db2://10.1.10.162:50000/mydb#username = root#password = root# Mysqldriver = com.mysql.jdbc.Driverurl = jdbc:mysql://localhost:3306/mydb?useUnicode=true&characterEncoding=utf-8username = rootpassword = 1234initialPoolSize = 1minPoolSize = 1maxPoolSize =10

(5)log4j.properties(log4j框架属性文件)

log4j日志属性配置文件

# log4j.propertieslog4j.rootLogger=warn,consolelog4j.appender.console=org.apache.log4j.ConsoleAppenderlog4j.appender.console.layout=org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=[%d] [%t] (%F:%L) %-5p %c - %m%nlog4j.appender.console.Encoding=GB18030log4j.appender.file=org.apache.log4j.RollingFileAppenderlog4j.appender.file.MaxFileSize=10240KBlog4j.appender.file.MaxBackupIndex=100log4j.appender.file.Encoding=GB18030log4j.appender.file.layout=org.apache.log4j.PatternLayoutlog4j.appender.file.layout.ConversionPattern=[%d] [%t] (%F:%L) %-5p %c - %m%nlog4j.appender.ROLLING_FILE_CUSTOMER=org.apache.log4j.RollingFileAppenderlog4j.appender.ROLLING_FILE_CUSTOMER.Threshold=debuglog4j.appender.ROLLING_FILE_CUSTOMER.Append=truelog4j.appender.ROLLING_FILE_CUSTOMER.MaxFileSize=1024KBlog4j.appender.ROLLING_FILE_CUSTOMER.MaxBackupIndex=30log4j.appender.ROLLING_FILE_CUSTOMER.layout=org.apache.log4j.PatternLayoutlog4j.appender.ROLLING_FILE_CUSTOMER.layout.ConversionPattern=%d - %c:%L - %-5p %c %x - %m%nlog4j.appender.ROLLING_FILE_WORKMANAGER=org.apache.log4j.RollingFileAppenderlog4j.appender.ROLLING_FILE_WORKMANAGER.Threshold=debuglog4j.appender.ROLLING_FILE_WORKMANAGER.Append=truelog4j.appender.ROLLING_FILE_WORKMANAGER.MaxFileSize=1024KBlog4j.appender.ROLLING_FILE_WORKMANAGER.MaxBackupIndex=30log4j.appender.ROLLING_FILE_WORKMANAGER.layout=org.apache.log4j.PatternLayoutlog4j.appender.ROLLING_FILE_WORKMANAGER.layout.ConversionPattern=%d - %c:%L - %-5p %c %x - %m%nlog4j.appender.ROLLING_FILE_RSS=org.apache.log4j.RollingFileAppenderlog4j.appender.ROLLING_FILE_RSS.Threshold=debuglog4j.appender.ROLLING_FILE_RSS.Append=truelog4j.appender.ROLLING_FILE_RSS.MaxFileSize=1024KBlog4j.appender.ROLLING_FILE_RSS.MaxBackupIndex=30log4j.appender.ROLLING_FILE_RSS.layout=org.apache.log4j.PatternLayoutlog4j.appender.ROLLING_FILE_RSS.layout.ConversionPattern=%d - %c:%L - %-5p %c %x - %m%n

(6)sqlMapConfig.xml(Ibatis框架配置文件)

该文件主要负责指定sql映射文件，即与model层对象对应的映射文件

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" "http://www.ibatis.com/dtd/sql-map-config-2.dtd"><sqlMapConfig>  <!-- 配置settings -->  <settings lazyLoadingEnabled="true" useStatementNamespaces="false"/>  <!-- 配置sql映射文件 -->  <sqlMap resource="com/archie/model/User.xml"/></sqlMapConfig>

6.Java代码编写

根据包目录，可以看出分成model层,dao层,service层和web层,另外附加test层,用于java环境测试

(1)model层(User.java+User.xml)

   User.java代码

package com.archie.model;public class User {    private int id;      private String username;      private String password;         public User(){        }        public User(int id){    this.id = id;    }        public User(int id, String username){    this.id = id;    this.username = username;    }        public User(String username, String password) {this.username = username;this.password = password;}        public User(int id, String username, String password){    this.id = id;    this.username = username;    this.password = password;    }          public int getId() {          return id;      }      public void setId(int id) {          this.id = id;      }      public String getUsername() {          return username;      }      public void setUsername(String username) {          this.username = username;      }      public String getPassword() {          return password;      }      public void setPassword(String password) {          this.password = password;      }}

   User.xml代码(model层对象的sql映射文件,被dao层调用,本质是sql语句集合,所有相关的sql均于此)

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"  "http://ibatis.apache.org/dtd/sql-map-2.dtd"><sqlMap namespace="User"><typeAlias alias="User" type="com.archie.model.User"/><select id="findAllUser" resultClass="User" >      select * from t_user  </select>  <select id="findUserByID" resultClass="User" parameterClass="int">      select * from t_user where id=#id#    </select>        <select id="getTotalCount" resultClass="int">        select count(*) from t_user    </select>        <select id="searchUsers" resultClass="User" parameterClass="User">      select * from t_user      <dynamic prepend="where">          <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->          <isNotEmpty prepend="and" property="username">          (username like '%$username$%')          </isNotEmpty>          <isNotEmpty prepend="and" property="password">          (password like '%$password$%')          </isNotEmpty>      </dynamic>    </select>    <select id="findUserByNameAndPassword" resultClass="User" parameterClass="User">      select * from t_user where username=#username# and password=#password#    </select>    <insert id="insertUser" parameterClass="User">      insert into t_user(id,username,password) values(null,#username#,#password#)  </insert>    <update id="updateUser" parameterClass="User">      update t_user     set username = #username#,    password=#password#    where id=#id#  </update><delete id="deleteUser" parameterClass="int">      delete from t_user where id=#id#  </delete>    <delete id="deleteUserByLike" parameterClass="User">  delete from t_user  <dynamic prepend="where">          <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->        <isNotEmpty prepend="and" property="username">          (username like '%$username$%')          </isNotEmpty>          <isNotEmpty prepend="and" property="password">          (password like '%$password$%')          </isNotEmpty>      </dynamic>  </delete>  </sqlMap>

(2)dao层(数据服务层,BaseDao.java+UserDao.java)

   BaseDao.java(公共Dao,其他Dao均继承它)

package com.archie.dao;import javax.annotation.PostConstruct;import javax.annotation.Resource;import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;import com.ibatis.sqlmap.client.SqlMapClient;public class BaseDao extends SqlMapClientDaoSupport {@Resource(name="sqlMapClient")  //通过bean名称注入private SqlMapClient sqlMapClient;@PostConstruct  //完成sqlMapClient初始化工作public void initSqlMapClient(){super.setSqlMapClient(sqlMapClient);}}

   UserDao.java(user数据服务层)

package com.archie.dao;import java.util.List;import org.springframework.stereotype.Component;import com.archie.model.User;@Component  //将UserDao类注入到bean里面public class UserDao extends BaseDao {public boolean addUser(User user) throws Exception{User bean = (User)getSqlMapClientTemplate().insert("insertUser", user);return bean != null ? true : false;}public boolean deleteUser(int id) throws Exception{int result = getSqlMapClientTemplate().delete("deleteUser", id);return result > 0 ? true : false;}public User getUserById(int id) throws Exception{return (User)getSqlMapClientTemplate().queryForObject("findUserByID", id);}@SuppressWarnings("unchecked")public List getAllUsers() throws Exception{return getSqlMapClientTemplate().queryForList("findAllUser");}public boolean updateUser(User user) throws Exception{int result = getSqlMapClientTemplate().update("updateUser", user);return result > 0 ? true : false;}public User getUserByNameAndPassword(User user) throws Exception{return (User)getSqlMapClientTemplate().queryForObject("findUserByNameAndPassword", user);}public int getTotalCount() throws Exception{return (Integer)getSqlMapClientTemplate().queryForObject("getTotalCount");}@SuppressWarnings("unchecked")public List getUsersByLike(User user) throws Exception{return getSqlMapClientTemplate().queryForList("searchUsers", user);}public int deleteUserByLike(User user) throws Exception{int result = getSqlMapClientTemplate().delete("deleteUserByLike", user);if (result > 0) {System.out.println("模糊删除成功！");}else {System.out.println("没有匹配的记录1");}return result;}}

(3)service层(业务服务层,UserService.java)

   UserService.java代码如下

package com.archie.service;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Component;import org.springframework.transaction.annotation.Transactional;import com.archie.dao.UserDao;import com.archie.model.User;@Component  //将UserService类注入到bean里面@Transactional  //注入事务管理public class UserService {@Resource(name="userDao")  // 通过名称注入到bean里面private UserDao userDao;public User login(User user) throws Exception{return userDao.getUserByNameAndPassword(user);}public void addUser(User user) throws Exception{userDao.addUser(user);}public void deleteUser(int id) throws Exception{boolean bool = userDao.deleteUser(id);if (!bool) {System.out.println("删除的记录不存在！");throw new RuntimeException();}}public User getUserById(int id) throws Exception{User user = userDao.getUserById(id);if (user == null) {return null;}return userDao.getUserById(id);}public void updateUser(User user) throws Exception{userDao.updateUser(user);}public int getTotalCount() throws Exception{return userDao.getTotalCount();}@SuppressWarnings("unchecked")public List getUsersByLike(User user) throws Exception{return userDao.getUsersByLike(user);}public int deleteUserByLike(User user) throws Exception{return userDao.deleteUserByLike(user);}public void insertUsers(List<User> list) throws Exception{for (int i = 0; i < list.size(); i++) {if (i > 3) {System.out.println("列表太长，中断事务");throw new RuntimeException("中断事务异常,当列表长度大于3的时候故意抛出，看看事务是否回滚");}User user = list.get(i);userDao.addUser(user);}}}

(4)web层(界面控制层,UserController.java)

   UserController.java

package com.archie.web;import javax.annotation.Resource;import javax.servlet.http.HttpSession;import javax.validation.Valid;import org.springframework.stereotype.Controller;import org.springframework.validation.BindingResult;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.servlet.ModelAndView;import com.archie.model.User;import com.archie.service.UserService;@Controller@RequestMapping("/user/*")public class UserController {  @Resource(name="userService") private UserService userService; private final String LIST="redirect:/detail";   /**     * 登录     * @param user     * @param session     * @return     */    @RequestMapping("/login")    public ModelAndView login(@Valid User user,BindingResult result,HttpSession session) throws Exception{      if(!result.hasErrors()){        User loginUser=userService.login(user);        if(loginUser!=null){            session.setAttribute("USER", loginUser);            return new ModelAndView(LIST);        }else{            return new ModelAndView("redirect:/");        }      }else{          ModelAndView view=new ModelAndView();          view.setViewName("redirect:/");          view.addObject("error", result.getAllErrors());          return view;      }    }        /**     * 跳转至添加页     * @return     */    @RequestMapping(value="/toAdd",method=RequestMethod.GET)    public ModelAndView toAdd(){        return new ModelAndView("user/add");    }    /**     * 保存     * @param user     * @return     */    @RequestMapping(value="/add",method=RequestMethod.POST)    public ModelAndView add(@Valid User user,BindingResult result) throws Exception{        if(result.hasErrors()){            return new ModelAndView("user/add","error", result.getAllErrors());        }else{            userService.addUser(user);            return new ModelAndView(LIST);            }    }    /**     * 根据ID删除     * @param id     * @return     */    @RequestMapping(value="/delete/{id}")    public ModelAndView delete(@PathVariable int id) throws Exception{        userService.deleteUser(id);        return new ModelAndView(LIST);    }    /**     * 跳转至编辑页面     * @param id     * @return     */    @RequestMapping(value="/edit/{id}")    public ModelAndView edit(@PathVariable int id) throws Exception{        User user=userService.getUserById(id);        return new ModelAndView("user/edit","user",user);    }    /**     * 编辑     * @param user     * @return     */    @RequestMapping(value="/edit")    public ModelAndView update(@Valid User user,BindingResult result)throws Exception{        ModelAndView view=new ModelAndView();        if(result.hasErrors()){            view.addObject("error", result.getAllErrors());            view.setViewName("user/edit");            return view;        }else{         userService.updateUser(user);         return new ModelAndView(LIST);        }    }}

(5)test层(Java环境下测试)
   TestUserController.java

package com.archie.test;import java.util.ArrayList;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.archie.model.User;import com.archie.service.UserService;public class TestUserController {public static void main(String[] args) throws Exception{ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");UserService userService = (UserService)context.getBean("userService");List<User> list = new ArrayList<User>();list.add(new User("wang", "wang"));list.add(new User("wang", "wang"));list.add(new User("wang", "wang"));userService.insertUsers(list);System.out.println("恭喜恭喜，添加成功！");userService.deleteUser(26);System.out.println("恭喜恭喜，删除成功！");User beanUser = userService.getUserById(21);if (beanUser != null) {System.out.println("恭喜恭喜，查找成功！");}else {System.out.println("不好意思，您所查找的用户不存在！");}int totalCount = userService.getTotalCount();System.out.println("TotalCount="+totalCount);int result = userService.deleteUserByLike(new User("wang","wang"));System.out.println("模糊删除的记录条数是："+result);List users = userService.getUsersByLike(new User("meimei","1234"));if (users == null || users.size() == 0) {System.out.println("没有匹配的记录2");}else {for (int i = 0; i < users.size(); i++) {User user = (User)users.get(i);System.out.println("username="+user.getUsername()+",password="+user.getPassword());}}System.out.println("length="+users.size());}}
