Java 系列之spring学习--springmvc注解方式（五）

一、springmvc注解方式

　　注解方式使用的更多，更加灵活。在上一篇的博客的基础上修改springmvc-servlet.xml配置文件。

<?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:tx="http://www.springframework.org/schema/tx"
    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-3.2.xsd  
    http://www.springframework.org/schema/tx  
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.2.xsd 
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
    <!-- <bean name="/hello" class="springmvc.HelloController"></bean> -->
    <!-- 要使注解生效，需要配置这几个属性，它会扫描controller中的注解 -->  
    <context:component-scan base-package="Controller" />  
    <mvc:default-servlet-handler />  
    <mvc:annotation-driven />  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <property name="prefix" value="/WEB-INF/JSP/"/> 
        <property name="suffix" value=".jsp"/> 
        </bean>
</beans>

二、在controller下新建一个类

package Controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
 
@Controller
public class UserController {
     
    @RequestMapping(value="/index")
    public ModelAndView index()
    {
        System.out.println("index");
        ModelAndView mv=new ModelAndView();
        mv.setViewName("hello");
        return mv;
         
    }
}
