springMVC+MyBatis+Spring 整合(2)

mybatis 与Spring 的整合.　　

1.导入Spring 和Springmvc的包

pom

</project>

2. 添加spring-mvc.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" 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-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
    <context:component-scan base-package="com.sd" />

    <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>

    <!-- 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">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
            </list>
        </property>
    </bean>

    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" />

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding">
            <value>UTF-8</value>
        </property>
        <property name="maxUploadSize">
            <value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 -->
        </property>
        <property name="maxInMemorySize">
            <value>4096</value>
        </property>
    </bean>

</beans>

3.添加spring-application.xml 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:aop="http://www.springframework.org/schema/aop"
    xmlns:c="http://www.springframework.org/schema/c" xmlns:cache="http://www.springframework.org/schema/cache"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"
    xmlns:lang="http://www.springframework.org/schema/lang" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:task="http://www.springframework.org/schema/task"
    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-4.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">
    <!-- 自动扫描dao和service包(自动注入) -->
    <context:component-scan base-package="com.sd" />
    <aop:aspectj-autoproxy />
    <!-- <import resource="spring-mybatis.xml" /> -->

</beans>

4 . 修改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_3_0.xsd"
    id="WebApp_ID" version="3.0">
    <display-name>mybatis</display-name>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-*.xml</param-value>
    </context-param>
    <filter>
        <description>字符集过滤器</description>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <description>字符集编码</description>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <listener>
        <description>spring监听器</description>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>
    <servlet>
        <description>spring mvc servlet</description>
        <servlet-name>springMvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <description>spring mvc 配置文件</description>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>/index.jsp</welcome-file>
    </welcome-file-list>
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

5. controller 如下

 package com.sd.test.controller;

 import java.io.IOException;

 import javax.annotation.Resource;
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;

 import org.springframework.stereotype.Controller;
 import org.springframework.web.bind.annotation.RequestMapping;

 import com.sd.test.model.TTest;
 import com.sd.test.service.TestService;

 @Controller
 @RequestMapping("/test")
 public class TestController {
     @Resource
     private TestService testService;

     @RequestMapping("selectOne")
     public void findById(HttpServletRequest request,
             HttpServletResponse response) throws IOException {
         String id = request.getParameter("id");
         Object obj = this.testService.selectOne(Integer.parseInt(id));
         response.getWriter().print(obj);
     }

     @RequestMapping("save")
     public void save(HttpServletRequest request, HttpServletResponse response) {
         String name = request.getParameter("name");
         TTest t = new TTest();
         t.setUsername(name);
         this.testService.save(t);

     }

     @RequestMapping("tsave")
     public void tsave(HttpServletRequest request, HttpServletResponse response) {
         String name = request.getParameter("name");
         TTest t = new TTest();
         t.setUsername(name);
         int i = (Integer) this.testService.put(t);
         System.out.println(i);
     }

 }

serviceImpl 如下:

package com.sd.test.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.sd.test.dao.TTestMapper;
import com.sd.test.model.TTest;
import com.sd.test.service.TestService;

@Service
public class TestServiceImpl implements TestService {

    // @Resource
    // private TTestMapper mapper;

    @Override
    public void save(Object obj) {
        // int i = this.mapper.insert((TTest) obj);
        // System.out.println("save = " + i);
        System.out.println("save");

    }

    @Override
    public Object selectOne(Object obj) {
        System.out.println("selectOne");
        TTest tt = null;
        // TTest tt = this.mapper.selectByPrimaryKey(Integer.parseInt(obj
        // .toString()));
        return tt;
    }

    @Override
    public Object put(Object obj) {
        System.out.println("put");
        // return this.mapper.insert((TTest) obj);
        return null;
    }

}

启动项目.访问http://localhost:8080/prot/test/selectOne.do?id=1

控制台:

 selectOne

到此为止, spring mvc 部署成功.
