SpringMVC接受前端参数的几中方式

1.直接将表单中的数据写入形参中

@RequestMapping
public String showIndex(String name,String pass){
    System.Out.Println("name:"+name);
    System.Out.Println("pass:"+pass);
}

 

2.使用HttpServletRequest

@RequestMapping("/")
public String showIndex(HttpServletRequest req) {
    String name = req,getParmeter("name");
    String pass = req.getParmeter("pass");
}

 

3.使用和保单数据一样的javaBean

class ModelMap{
    private String name;
    private String pass;



}
@RequestMapping("/")
public String showIndex(ModelMap model) {
        syso(model.name);
        syso(model.pass);
    }
