URL地址

使用@RequestMapping注解
可以在类/方法上加

@Controller
@RequestMapping("url")//http://localhost:8080/url/u01.do  类级别
public class UrlController {

    @RequestMapping("u01")//方法级别
    public ModelAndView fun(){
        ModelAndView mv=new ModelAndView();
        mv.addObject("fun","function");
        mv.setViewName("hello");
        return mv;
    }

    @RequestMapping(value = {"/u03","u04"},method = {RequestMethod.GET })//方法级别
    public ModelAndView fun1(){
        ModelAndView mv=new ModelAndView();
        mv.addObject("fun","function1");
        mv.setViewName("hello");
        return mv;
    }

    @RequestMapping(params = "u05")//访问时必须有参数才能访问
    public ModelAndView fun2(){
        ModelAndView mv=new ModelAndView();
        mv.addObject("fun","function2");
        mv.setViewName("hello");
        return mv;
    }
}
