<!-- 使用 mvc:annotation-driven代替上边注解映射器和注解适配器配置
mvc:annotation-driven默认加载很多的参数绑定方法,
比如json转换解析器就默认加载了,如果使用mvc:annotation-driven不用配置上边的RequestMappingHandlerMapping和RequestMappingHandlerAdapter
实际开发时使用mvc:annotation-driven
-->
1.springmvc.xml配置
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 添加注解模式 可以扫描controller、service、... 这里让扫描controller,指定controller的包--> <context:component-scan base-package="controller"/> <!-- 配置注解处理器映射器,功能:寻找执行类Controller --> <mvc:annotation-driven></mvc:annotation-driven> <!-- 配置sprigmvc视图解析器:解析逻辑视图 后台返回逻辑视图:index 视图解析器解析出真正物理视图: 前缀+逻辑试图+后缀====/WEB-INF/jsps/index.jsp --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsps/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
2.controller层控制类编写
package controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller public class TestController { @RequestMapping("/test.do") public ModelAndView handleRequest() { ModelAndView mv=new ModelAndView(); mv.addObject("hello","Welcome To MVC !"); mv.setViewName("first"); return mv; } }
3.访问
