spring+spring MVC+mybatis 框架搭建

1.新建一个javaWeb工程Test，创建时记得勾选web.xml文件。

2.导入需要的jar包，Mybatis所有的jar，spring所有的jar，mysql驱动包。

这里mybatis和spring的jar包就不介绍了，看看其他的包：

mysql驱动包：mysql-connector-java-5.1.35-bin.jar。

数据库连接的两个包：commons-dbcp-1.2.jar，commons-pool.jar

mybatis和spring的整合包：mybatis-spring-1.2.2.jar

接下来是配置文件：

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" 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>Test</display-name>

<context-param> <!--全局范围内环境参数初始化-->
<param-name>contextConfigLocation</param-name> <!--参数名称-->
<param-value>classpath:mybatis-spring.xml</param-value> <!--参数取值-->
</context-param>

<!--以下配置的加载顺序:先 ServletContext >> context-param >> listener >> filter >> servlet >> spring-->

<filter> <!-- 用来声明filter的相关设定,过滤器可以截取和修改一个Servlet或JSP页面的请求或从一个Servlet或JSP页面发出的响应-->
<filter-name>encodingFilter</filter-name> <!--指定filter的名字-->
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <!--定义filter的类的名称-->
<async-supported>true</async-supported> <!--设置是否启用异步支持-->
<init-param><!--用来定义参数,若在Servlet可以使用下列方法来获得:String param_name=getServletContext().getInitParamter("param-name里面的值");-->
<param-name>encoding</param-name> <!--参数名称-->
<param-value>UTF-8</param-value> <!--参数值-->
</init-param>
</filter>
<filter-mapping><!--用来定义filter所对应的URL-->
<filter-name>encodingFilter</filter-name> <!--指定对应filter的名字-->
<url-pattern>/*</url-pattern> <!--指定filter所对应的URL-->
</filter-mapping>

<!--例:spring监听器-->
<listener> <!--用来设定Listener接口-->
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><!--定义Listener的类名称-->
</listener>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

<servlet> <!--用来声明一个servlet的数据 -->
<servlet-name>Test</servlet-name> <!--指定servlet的名称-->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--指定servlet的类名称,这里配置了前端控制器-->
<init-param><!--用来定义参数,可有多个init-param。在servlet类中通过getInitParamenter(String name)方法访问初始化参数 -->
<param-name>contextConfigLocation</param-name> <!--参数名称-->
<param-value>classpath:spring-mvc.xml</param-value> <!--参数值-->
</init-param>
<load-on-startup>1</load-on-startup><!--当值为正数或零时：Servlet容器先加载数值小的servlet，再依次加载其他数值大的servlet.-->
<async-supported>true</async-supported><!--设置是否启用异步支持-->
</servlet>
<servlet-mapping><!--用来定义servlet所对应的URL-->
<servlet-name>Test</servlet-name> <!--指定servlet的名称-->
<url-pattern>/</url-pattern> <!--指定servlet所对应的URL-->
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>

<welcome-file>default.html</welcome-file>

<!-- 3、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.lihui.*"/>
</beans>

注意：文件中的很多路径和包名都要改成你自己工程中的。

创建TestController.java

package com.lihui.controller;

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

@Controller
@RequestMapping(value="/controller")
public class TestController {

@RequestMapping(value="/get",method = RequestMethod.GET)
@ResponseBody
public void testController() {
System.out.println("输出");
}

}
