七、向前台传递参数

复制代码
    //pass the parameters to front-end
    @RequestMapping("/show")
    public String showPerson(Map<String,Object> map){
        Person p =new Person();
        map.put("p", p);
        p.setAge(20);
        p.setName("jayjay");
        return "show";
    }
复制代码

前台可在Request域中取到"p"

 

     //D:\Indigo_workspace2\TrySpringMVC\src\test\SpringMVC\personController.java
     //http://localhost:8080/TrySpringMVC/person/showPerson
   //pass the parameters to front-end
     //前台可在Request域中取到"p"
     @RequestMapping("/show")
     public String showPerson(Map<String,Object> map){
         Person p =new Person();
         map.put("p", p);
         p.setAge(20);
         p.setName("jayjay");
         return "show";
     }
     //http://localhost:8080/TrySpringMVC/person/show
     //Person :
     //jayjay-20
