springMVC+MyBatis+Spring 整合(2)

mybatis 与Spring 的整合.　　

1.导入Spring 和Springmvc的包

pom

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>

</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/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang.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 ObjectselectOne(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.
