spring mvc+ spring +mybatis

首先，修改web.xml，添加配置文件路由以及格式过滤

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="3.0" 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_3_0.xsd">
 <display-name>Archetype Created Web Application</display-name>
      <servlet-mapping>
         <servlet-name>springmvc</servlet-name>
         <url-pattern>/</url-pattern>
     </servlet-mapping>

 <!-- 将数据过滤成UTF-8 -->
 <filter>
     <filter-name>encodingFilter</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>encodingFilter</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>  

 <!-- 添加配置文件路由 -->
 <servlet>
         <servlet-name>springmvc</servlet-name>
         <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
         </servlet-class>
         <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>classpath:applicationContext.xml,classpath:springmvc-config.xml</param-value>
         </init-param>
         <load-on-startup>1</load-on-startup>
 </servlet>
 </web-app>

修改applicationContext.xml，定义数据源，添加事务管理，持久层的bean（Dao）

 <?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:context="http://www.springframework.org/schema/context"

  xmlns:aop="http://www.springframework.org/schema/aop"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

     <context:component-scan base-package="com.zqc.share" />
 <!--     <context:property-placeholder location="classpath:db.properties" />
  -->
      <!-- 定义数据源Bean，使用C3P0数据源实现 -->
     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
         <!-- 指定连接数据库的驱动 -->
         <property name="driverClass" value="com.mysql.jdbc.Driver"/>
         <!-- 指定连接数据库的URL -->
         <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/share"/>
         <!-- 指定连接数据库的用户名 -->
         <property name="user" value="root"/>
         <!-- 指定连接数据库的密码 -->
         <property name="password" value="1111"/>
         <!-- 指定连接数据库连接池的最大连接数 -->
         <property name="maxPoolSize" value="40"/>

         <property name="maxIdleTime" value="20"/>
     </bean>
     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:mybatis_config.xml"></property>
     </bean>
     <bean id="newsDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
       <property name="mapperInterface" value="com.zqc.share.dao.news.NewsDao"></property>
        <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
     </bean> 

     <!-- 事务管理 -->
     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
         <property name="dataSource" ref="dataSource"></property>
     </bean>
     <tx:annotation-driven transaction-manager="transactionManager" />
 </beans>  

配置springmvc

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/util
          http://www.springframework.org/schema/util/spring-util.xsd">

    <context:component-scan base-package="com.zqc.share.controller"/>
    <context:component-scan base-package="com.zqc.share.service"/>
    <context:component-scan base-package="com.zqc.share.dao"/>
    <context:component-scan base-package="com.zqc.share.framework"/>
    <context:component-scan base-package="com.zqc.share.model"/>
  <!-- 自动加载注解-->
       <mvc:annotation-driven/>
       <bean class="com.zqc.share.framework.listener.InitListener"/>

       <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
            <property name="supportedMediaTypes">
               <list>
                  <value>text/html;charset=UTF-8</value>
               </list>
            </property>
       </bean>
       <context:annotation-config/> 

        <mvc:interceptors>
           <bean class="com.zqc.share.framework.interceptor.TokenValidateInterceptor" />
        </mvc:interceptors>

       <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <property name="prefix" value="/WEB-INF/jsp/"/>
           <property name="suffix" value=".jsp"/>
    </bean>

</beans>

控制层代码：NewsController

 @Controller
 public class NewsController {

     @Autowired
     NewsService newsService;

        @ResponseBody
     @RequestMapping(value = "/addNews", method = RequestMethod.POST, consumes = "application/json")
     public Object addNews(@RequestBody News news){

         com.zqc.share.framework.model.ResponseBody responseBody = new com.zqc.share.framework.model.ResponseBody();
         int status = newsService.addNews(news);
         if(status != 0 ){
             responseBody.setErrorCode(0);
         }
         else {
             responseBody.setErrorMsg("添加新闻失败");
             responseBody.setErrorCode(1);
         }

         return responseBody;
     }
     }
 }

其中responseBody用于封装返回值，用过springmvc的@ResponseBody解析成json

 public class ResponseBody {

     private String responseContext;

     private String errorMsg;

     private int errorCode;

     public String getResponseContext() {
         return responseContext;
     }

     public void setResponseContext(String responseContext) {
         this.responseContext = responseContext;
     }

     public String getErrorMsg() {
         return errorMsg;
     }

     public void setErrorMsg(String errorMsg) {
         this.errorMsg = errorMsg;
     }

     public int getErrorCode() {
         return errorCode;
     }

     public void setErrorCode(int errorCode) {
         this.errorCode = errorCode;
     }

 }

接下来是service层

 @Service
 public class NewsService {

     @Resource(name="newsDao")
     NewsDao newsDao;

         public int addNews(News news){
         return newsDao.addNews(news);
     }

 }

Dao层

 public interface NewsDao {

     public int addNews(@Param("news") News news);

 }

NewsDao.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="com.zqc.share.dao.news.NewsDao">
    <insert id="addNews" parameterType="com.zqc.share.model.news.News">
         insert into news (title,description,head_image,publishtime,readtimes,user_id,topic_id,goodcount,badcount)
              values(#{news.title},#{news.description},#{news.head_image},#{news.publishtime},#{news.readtimes},#{news.user_id},#{news.topic_id},#{news.goodcount},#{news.badcount})
     </insert>
 </mapper>

配置路由

<?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>
    <mappers>
        <mapper resource="com/zqc/share/dao/news/NewsDao.xml" />
    </mappers>
</configuration>

完工。。。。
