SpirngMVC 请求参数

非resful格式

传递普通参数

    @GetMapping("/t1")
    public String test(@RequestParam("name") String name, Model model){
        System.out.println(name);
        model.addAttribute("msg", name);
        return "hi";
    }

2、传递对象

pojo实体类

package com.wt.dao;

public class User {
    private int id;
    private String name;
    private int age;

    public User() {
    }

    public User(int id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

    @GetMapping("/t2")
    public String test2(User user){
        System.out.println(user);
        return "hi";
    }

url: http://localhost:8090/t2?name=tom&id=2&age=4

注意：若参数与实体类不对应，则为空
