SpringMVC注解开发(一)-简单注解

定义MyController类使用注解取代原先的继承

package top.wyyblog.Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver;

@Controller //表示当前类是一个处理器
@RequestMapping("/page") //命名空间
public class MyController {
	
//	@RequestMapping("/my*.do") 正则 以my开头的都能访问
//	@RequestMapping("/*/my.do") 路径级数的绝对匹配，即要求在page与my.do之间必须要有一级路径
//	@RequestMapping("/**/my.do") 要求在page与my.do之间可以包含2级以内的路径
//	@RequestMapping(value="/my.do",method=RequestMethod.POST) 要求使用post进行访问
//	@RequestMapping(value="/my.do",params= {"name","!age"}) 请求是要携带name参数并且不能携带age参数
	@RequestMapping("/my.do")
	public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
		ModelAndView mView = new ModelAndView();
		mView.addObject("message", "hello springMVC！！！");
		mView.setViewName("/WEB-INF/jsp/index.jsp");
		return mView;
	}
