Struts2+Spring4+myBatis3整合

来源：互联网发布：linux less 退出编辑：程序博客网时间：2024/05/29 03:58

终于开始整合了，三大工具各司其职。Struts负责与jsp交互，Spring针对javaBean的生命周期进行管理，myBatis负责数据库部分。

个人认为整合最重要的是找对相应的包，不然包之间就可能出现冲突，然后一直报错。以下是千辛万苦测试成功的包：
这里写图片描述

配置web.xml

<?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">  <display-name></display-name>   <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>  <!-- spring 加载文件配置 -->  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>  <!-- spring监听器配置 -->  <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <!-- 设置spring字符编码过滤器 -->    <filter>      <filter-name>characterEncoding</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>    </filter>    <filter-mapping>      <filter-name>characterEncoding</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>     <!-- 配置Struts2 -->    <filter>      <filter-name>struts2</filter-name>      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>      <filter-name>struts2</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>  </web-app>

配置applicationContext.xml

applicationContext.xml里的重点：
⑴<context:annotation-config />，写了这句话才能使用注解的方式配置Bean。
⑵<context:component-scan base-package="gyt.frame.first"></context:component-scan>,配置需要扫描的包。如果某个类的头上带有特定的注解@Component，@Repository，@Service，@Controller，就会将这个对象作为Bean注册进Spring容器。扫描多个包用逗号隔开。
⑶<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:MyBatis.xml" /> <property name="dataSource" ref="dataSource" /> </bean>，用于创建工厂Bean。
⑷<bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean"> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> <property name="mapperInterface" value="gyt.frame.first.UserDao" /> </bean>，创建dao bean（只需提供接口不需提供实现类）。学习于http://blog.csdn.net/hupanfeng/article/details/21454847。

配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"    "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>     <!-- 指定默认编码集 ，作用于HttpServletRequest的setCharacterEncoding（）和freemarker，vilocity的输出 -->      <constant name="struts.i18n.encoding" value="UTF-8"/>      <!-- 当struts配置文件修改时是否自动加载 -->      <constant name="struts.configuration.xmlreload" value="true"/>      <!-- 开发模式下打印详细的错误信息，默认为false -->        <constant name="struts.devMode" value="true"/>      <!-- 标准的UI主题，默认的UI主题为xhtml，可以为simple,xhtml或ajax -->      <constant name="struts.ui.theme" value="xhtml"/>    <package name="test" namespace="/test" extends="struts-default">          <action name="hello" class="gyt.frame.first.HelloAction">              <result name="success">/jsps/HelloAction.jsp</result>          </action>       </package>    <package name="user" namespace="/user" extends="struts-default">          <action name="UserAction" class="gyt.frame.first.UserAction">              <result name="success">index.jsp</result>          </action>       </package> </struts>

配置myBatis.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD  Config 3.0//EN"               "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <!-- 映射文件，存放sql语句的配置文件 -->    <mappers>        <mapper resource="gyt/frame/first/UserMappers.xml" />    </mappers></configuration>

配置log4j.properties

log4j.rootLogger=info,A1  log4j.logger.com.mchange=warn,A1  log4j.additivity.com.mchange=false  log4j.logger.org.hibernate=warn,A1  log4j.additivity.org.hibernate=false  log4j.logger.com.ibatis=warn,A1  log4j.additivity.com.ibatis=false  # ConsoleAppender  log4j.appender.A1=org.apache.log4j.ConsoleAppender  log4j.appender.A1.layout=org.apache.log4j.PatternLayout  log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss,SSS} [%c]-[%p] %m%n  # \u6253\u5370sql  log4j.logger.org.apache.ibatis=debug  log4j.logger.java.sql.Connection=debug  log4j.logger.java.sql.Statement=debug  log4j.logger.java.sql.PreparedStatement=debug  log4j.logger.java.sql.ResultSet=debug  #com.frame  log4j.logger.com.frame=debug

创建表

CREATE TABLE `user` (  `UserNo` varchar(10) NOT NULL,  `DepartmentNo` varchar(10) DEFAULT NULL,  `UserName` varchar(10) DEFAULT NULL,  `Password` char(16) DEFAULT NULL,  `Email` varchar(40) DEFAULT NULL,  PRIMARY KEY (`UserNo`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;

新建一个action类UserAction.java

/* Action注解单例问题交有spring管理后，action默认是单例模式。但是项目不能全部都采用单例，使用我们需要加入相关注解切换为非单例：在action上面配置，@Scope("prototype") ，每个请求都会new一个新的实例 */@Controller@Scope("prototype")public class UserAction extends ActionSupport {    /**     *      */    private static final long serialVersionUID = 1L;    @Autowired     //@Resource(name="userservice")    private UserService userservice;// 使用@Autowired,要写setter方法。    private User user=new User();//不写New,将报空指针     public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }    public UserService getUserservice() {        return userservice;    }    public void setUserservice(UserService userservice) {        this.userservice = userservice;    }    public static long getSerialversionuid() {        return serialVersionUID;    }    public String insert(){             user.setUserNo(user.getUserNo());        user.setDepartmentNo(user.getDepartmentNo());        user.setUserName(user.getUserName());        user.setPassword(user.getPassword());        user.setEmail(user.getEmail());        System.out.println(user.getUserName()+"   insert");        this.userservice.insert(user);        return SUCCESS;    }}

dao接口
UserDao.java

@Repository  @Transactionalpublic interface UserDao {    public void insert(User user);}

UserMappers.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="gyt.frame.first.UserDao">    <insert id="insert">        insert into User (UserNo,DepartmentNo,UserName,Password,Email) values(        #{UserNo,jdbcType=VARCHAR},        #{DepartmentNo,jdbcType=VARCHAR},        #{UserName,jdbcType=NUMERIC},        #{Password,jdbcType=VARCHAR},        #{Email,jdbcType=VARCHAR})    </insert>    </mapper>

这里注意namespace不要写错，id为类里面的某个方法。不然会报错。

service接口UserService.java

public interface UserService {    public void insert(User user);}

service实现类

/* Bean注解管理 Spring自动扫描管理Bean注解有四种配置模式，如下 @Service     用于业务层(service) 示例：@Service("baseService") @Controller  用于控制层(action)  示例：@Controller("baseAction") @Repository  用于数据访问层(dao) 示例：@Repository("baseDao") @Component   泛型配置(当组件不确定时用)，以上3种配置是基于此扩展 *//* @Service自动装配到Spring的容器，为其他组件提供服务； 通过@Transactional进行事务的管理； 通过@Resource注入UserDao对象。 */@Service@Transactional public class UserServiceImpl implements UserService{    @Autowired    private UserDao userdao;    public void insert(User user) {        this.userdao.insert(user);    }}

user.jsp

<body>   <!--   <form action="user/UserAction!insert.action">      编号：<input name="UserNo"><br>      部门编号：<input name="DepartmentNo"><br>    姓名：<input name="UserName"><br>     密码：<input name="Password"><br>     邮箱：<input name="Email"><br>               <input type="submit" value="确定">      </form>-->        <form action="user/UserAction!insert.action">      编号：<input name="user.UserNo"><br>      部门编号：<input name="user.DepartmentNo"><br>    姓名：<input name="user.UserName"><br>     密码：<input name="user.Password"><br>     邮箱：<input name="user.Email"><br>               <input type="submit" value="确定">      </form>   </body>
