建一个controller的包,写一个TestController.java
package controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; @Controller @RequestMapping("con") public class TestController { public TestController(){ System.out.println("123123123"); } @RequestMapping("test") @ResponseBody public String testmvc(){ System.out.println("testmvc"); return "testmvc"; } }
写构造函数方便查看是否扫描到
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-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 配置Controller扫描 -->
<context:component-scan base-package="controller"/>
<!-- 配置注解驱动 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<!-- <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
前缀
<property name="prefix" value="/WEB-INF/jsp/" />
后缀
<property name="suffix" value=".jsp" />
</bean> -->
</beans>
springmvc.xml中要配置需要扫描的controller的包,前缀后缀是action里跳转的jsp的前缀和后缀
在web.xml里添加springmvc的配置
<?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_2_5.xsd" version="2.5"> <display-name>smh</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 配置spring --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 配置监听器加载spring --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置过滤器,解决post的乱码问题 --> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter> <filter-name>openSessionInView</filter-name> <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>openSessionInView</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置SpringMVC --> <servlet> <servlet-name>boot-crm</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> <!-- 配置springmvc什么时候启动,参数必须为整数 --> <!-- 如果为0或者大于0,则springMVC随着容器启动而启动 --> <!-- 如果小于0,则在第一次请求进来的时候启动 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>boot-crm</servlet-name> <!-- 所有的请求都进入springMVC --> <url-pattern>*.action</url-pattern> </servlet-mapping> </web-app>
