1.导入jar包时,要在xml配置基础上加 spring-aop-4.2.2.RELEASE.jar （注解的时候需要）
2.编写controller的时候要annotation需要做相关配置即红色部分，而xml就是要实现controller的接口
（a）annotation配置时
package com.spring.hello; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import org.springframework.stereotype.Controller; @Controller public class HelloController { @RequestMapping("/hello") public ModelAndView hello(HttpServletRequest req,HttpServletResponse resp) { ModelAndView mv=new ModelAndView(); mv.addObject("msg", "第一个annotation"); mv.setViewName("Hello"); return mv; } }
package com.spring.hello;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloController implements Controller{
@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
ModelAndView mv=new ModelAndView();
mv.addObject("msg", "第一个SpringMvc");
mv.setViewName("Hello");
return mv;
}
}
3.在SpringMvc文件annotation不需要
<!-- 配置hanlderMapping --> <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean> <!-- 配置 handlerAdapter--> <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
但是要把
<!-- 配置请求和处理器 --> <bean name="/hello.do" class="com.spring.hello.HelloController"></bean>
修改成
<!-- 配置请求和处理器 --> <context:component-scan base-package="com.spring.hello"></context:component-scan>
SpringMvc的xml配置与annotation配置的例子的区别
