一、Spring-MyBatis的整合
参考"MyBatis3.x与Spring4.x整合"博文；
其中pom.xml：
<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/maven-v4_0_0.xsd">

</dependency>
<!-- jstl -->

<build>
<finalName>spring_springmvc_mybatis_test</finalName>
<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 -->
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>

</resources>
<plugins>
<!-- 指定maven项目的编译时使用的jdk版本 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
</build>
</project>
另：
@Resource
public class Teacher implements Serializable{
其中的@Resource防止出现Teacher类Class Not Found的情况；
二、整合Springmvc
1.配置springmvc.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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描该包，使SpringMVC认为包下用了@Controller注解的类是控制器 -->
<context:component-scan base-package="com.web.controller" />
<!--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.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动SpringMVC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>
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
2.配置web.xml：
<?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>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<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>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- ContextLoaderListener初始化Spring上下文时需要使用到的contextConfigLocation参数 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 配置spring.xml和spring-mybatis.xml这两个配置文件的位置，固定写法 -->
<param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value>
</context-param>
<!-- SpringMVC servlet -->
<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:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3.新建jsp/showTeacher.jsp页面：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%--加入该标签手动开启el功能--%>
<%@page isELIgnored="false"%>
<!DOCTYPE html>
<html>
<head>
<title>ssm</title>
<style type="text/css">
table,td{
border: 1px solid;
border-collapse: collapse;
}
</style>
</head>
<body>
${teacher.name}
</body>
</html>
4.建立TeacherController.java：
@Controller
@RequestMapping("/teacher")
public class TeacherController {
@Resource
private TeacherServiceI teacherService;
@RequestMapping("/showTeacher")
public String showTeacher(HttpServletRequest request, Model model) {
int id = Integer.parseInt((String) request.getParameter("id"));
Teacher t = teacherService.selectById(id);
model.addAttribute("teacher", t);
return "showTeacher";// showTeacher.jsp
}
}
启动之后，输入地址http://localhost:9080/spring_springmvc_mybatis_test/teacher/showTeacher?id=1，即可进行测试。
