【itoo】--spring+springmvc+maven+mybatis+Junit

【前言】

      最近小编在项目中用到了新的框架，接下来总结一下框架的基本结构。

【工程结构】

  ’ 

【pom.xml文件中引入依赖包】

【配置数据库连接属性（ jdbc.properties）】

jdbc_driverClassName=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://localhost:3306/mydays?useUnicode=true&characterEncoding=utf-8jdbc_username=rootjdbc_password=root

【配置spring配置文件（spring.xml）】

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd      http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context.xsd">    <!-- 引入jdbc配置文件 -->    <context:property-placeholder location="classpath:jdbc.properties"/>        <!-- 扫描文件（自动将servicec层注入） -->    <context:component-scan base-package="cn.springmvc.service"/></beans>

【spring和mybatis连接配置（spring-mybatis.xml）】

<?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:p="http://www.springframework.org/schema/p"  xmlns:context="http://www.springframework.org/schema/context"  xmlns:aop="http://www.springframework.org/schema/aop"  xmlns:tx="http://www.springframework.org/schema/tx"  xmlns:util="http://www.springframework.org/schema/util"  xsi:schemaLocation="http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd    http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-3.2.xsd    http://www.springframework.org/schema/tx    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd    http://www.springframework.org/schema/aop    http://www.springframework.org/schema/aop/spring-aop-3.2.xsd    http://www.springframework.org/schema/util     http://www.springframework.org/schema/util/spring-util-3.2.xsd">    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"    destroy-method="close" >    <property name="driverClassName">      <value>${jdbc_driverClassName}</value>    </property>    <property name="url">      <value>${jdbc_url}</value>    </property>    <property name="username">      <value>${jdbc_username}</value>    </property>    <property name="password">      <value>${jdbc_password}</value>    </property>    <!-- 连接池最大使用连接数 -->    <property name="maxActive">      <value>20</value>    </property>    <!-- 初始化连接大小 -->    <property name="initialSize">      <value>1</value>    </property>    <!-- 获取连接最大等待时间 -->    <property name="maxWait">      <value>60000</value>    </property>    <!-- 连接池最大空闲 -->    <property name="maxIdle">      <value>20</value>    </property>    <!-- 连接池最小空闲 -->    <property name="minIdle">      <value>3</value>    </property>    <!-- 自动清除无用连接 -->    <property name="removeAbandoned">      <value>true</value>    </property>    <!-- 清除无用连接的等待时间 -->    <property name="removeAbandonedTimeout">      <value>180</value>    </property>    <!-- 连接属性 -->    <property name="connectionProperties">      <value>clientEncoding=UTF-8</value>    </property>  </bean>        <!-- mybatis文件配置，扫描所有mapper文件 -->      <bean id="sqlSessionFactory"          class="org.mybatis.spring.SqlSessionFactoryBean"          p:dataSource-ref="dataSource"          p:configLocation="classpath:mybatis-config.xml"          p:mapperLocations="classpath:mapper/*.xml"/><!-- configLocation为mybatis属性 mapperLocations为所有mapper-->         <!-- spring与mybatis整合配置，扫描所有dao --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"        p:basePackage="cn.springmvc.dao"         p:sqlSessionFactoryBeanName="sqlSessionFactory"/>    <!-- 对数据源进行事务管理 -->  <bean id="transactionManager"         class="org.springframework.jdbc.datasource.DataSourceTransactionManager"        p:dataSource-ref="dataSource"/></beans>

【Java代码编写】

  cn.springmvc.model/User.java(用户基本信息)

package cn.springmvc.model;/** * 用户表 */public class User {private int id;private int state;private String nickname;public int getId() {return id;}public void setId(int id) {this.id = id;}public int getState() {return state;}public void setState(int state) {this.state = state;}public String getNickname() {return nickname;}public void setNickname(String nickname) {this.nickname = nickname;}
}cn.springmvc.dao/UserDAO.java(dao操作接口)

package cn.springmvc.dao;import cn.springmvc.model.User;public interface UserDAO {/** * 添加新用户 * @param user * @return */public int insertUser(User user);}

cn.springmvc.service/UserService.java(service层接口)

package cn.springmvc.service;import cn.springmvc.model.User;public interface UserService {public int insertUser(User user);}

cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)

package cn.springmvc.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import cn.springmvc.dao.UserDAO;import cn.springmvc.model.User;import cn.springmvc.service.UserService;@Servicepublic class UserServiceImpl implements UserService{@Autowiredprivate UserDAO userDAO;@Overridepublic int insertUser(User user) {// TODO Auto-generated method stubreturn userDAO.insertUser(user);}}

【mybatis配置（mybatis-config.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>        <!-- 命名空间 -->    <typeAliases>         <typeAlias alias="User" type="cn.springmvc.model.User"/>     </typeAliases>    <!-- 映射map -->    <mappers>    </mappers>

mapper/UserMapper.xml(mybatis的实现)

<?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="cn.springmvc.dao.UserDAO">                    <insert id="insertUser" parameterType="User" keyProperty="id">             insert into days_user(           state,         nickname)          values          (                 #{state},         #{nickname})         </insert>         </mapper>

【Junit测试】

 

cn.springmvc.test/UserTest.java(用户测试模块)

package cn.springmvc.test;import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import cn.springmvc.model.User;import cn.springmvc.service.UserService;public class UserTest {private UserService userService;@Beforepublic void before(){                                                                    @SuppressWarnings("resource")ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml","classpath:conf/spring-mybatis.xml"});userService = (UserService) context.getBean("userServiceImpl");}@Testpublic void addUser(){User user = new User();user.setNickname("你好");user.setState(2);System.out.println(userService.insertUser(user));}}

【springMVC模块搭建（web.xml）】

   

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>Archetype Created Web Application</display-name><!-- 读取spring配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:conf/spring.xml;classpath:spring-mybatis.xml</param-value></context-param><!-- 设计路径变量值 --><context-param><param-name>webAppRootKey</param-name><param-value>springmvc.root</param-value></context-param><!-- Spring字符集过滤器 --><filter><filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- 日志记录 --><context-param><!-- 日志配置文件路径 --><param-name>log4jConfigLocation</param-name><param-value>classpath:conf/log4j.properties</param-value></context-param><context-param><!-- 日志页面的刷新间隔 --><param-name>log4jRefreshInterval</param-name><param-value>6000</param-value></context-param><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- springMVC核心配置 --><servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:conf/spring-mvc.xml</param-value></init-param><load-on-startup>2</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!-- 错误跳转页面 --><error-page><!-- 路径不正确 --><error-code>404</error-code><location>/WEB-INF/errorpage/404.jsp</location></error-page><error-page><!-- 没有访问权限，访问被禁止 --><error-code>405</error-code><location>/WEB-INF/errorpage/405.jsp</location></error-page><error-page><!-- 内部错误 --><error-code>500</error-code><location>/WEB-INF/errorpage/500.jsp</location></error-page></web-app>

【MVC配置(spring-mvc.xml)】

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"  xmlns:p="http://www.springframework.org/schema/p"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:context="http://www.springframework.org/schema/context"  xmlns:mvc="http://www.springframework.org/schema/mvc"  xsi:schemaLocation="    http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd    http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-3.2.xsd    http://www.springframework.org/schema/mvc    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">        <!-- 扫描controller（controller层注入） -->   <context:component-scan base-package="cn.springmvc.controller"/>      <!-- 避免IE在ajax请求时，返回json出现下载 -->   <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean>   <!-- 对模型视图添加前后缀 -->     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"       p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/></beans>

【log4j日志记录搭建】

log4j.properties(日志记录的配置文件)

### set log levels ####log4j.rootLogger = debug , stdout , D , Elog4j.rootLogger = debug , stdout , D###  output to the console ###log4j.appender.stdout = org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayout#log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%nlog4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n### Output to the log file ###log4j.appender.D = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log log4j.appender.D.Append = truelog4j.appender.D.Threshold = ERROR log4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

【index.jsp】

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body><h1>欢迎你！！！</h1></body></html>

cn.springmvc.controller/UserComtroller.java(controller层控制)

package cn.springmvc.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controller@RequestMapping("/")public class UserController {@RequestMapping("index")public String index(){return "index";}}

最后将项目部署到service上发布即可。
