springMVC+MyBatis+Spring 整合(2)

mybatis 与Spring 的整合.　　

1.导入Spring 和Springmvc的包

</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">

            </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">

        <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"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

    <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.
