详解SpringBoot中5种类型参数传递和json数据传参的操作

 @RequestMapping("/commonParamDifferentname")
    @ResponseBody
    public String commonParamDifferentName(@RequestParam("name") String userName,int age){
        System.out.println("普通参数传递 userName ==> "+userName);
        System.out.println("普通参数传递 age ==> "+age);
        return "{'module':'common param different name'}";
    }

package com.example.domain;

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

    private Address address;


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

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    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;
    }
}

//POJO参数：请求参数与形参对象中的属性对应即可完成参数传递
    @RequestMapping("/pojoParam")
    @ResponseBody
    public String pojoParam(User user){
        System.out.println("pojo参数传递 user ==> "+user);
        return "{'module':'pojo param'}";
    }

package com.example.domain;
public class Address {
    private String province;
    private String city;

    @Override
    public String toString() {
        return "Address{" +
                "province='" + province + '\'' +
                ", city='" + city + '\'' +
                '}';
    }

    public String getProvince() {
        return province;
    }

    public void setProvince(String province) {
        this.province = province;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
}

  @RequestMapping("/pojoContainPojoParam")
    @ResponseBody
    public String pojoContainPojoParam(User user){
        System.out.println("pojo嵌套pojo参数传递 user ==> "+user);
        return "{'module':'pojo contain pojo param'}";
    }

@RequestMapping("/arrayParam")
    @ResponseBody
    public String arrayParam(String[] likes){
        System.out.println("数组参数传递 likes ==> "+ Arrays.toString(likes));
        return "{'module':'array param'}";
    }

@RequestMapping("/listParam")
    @ResponseBody
    public String listParam(@RequestParam List<String> likes){
        System.out.println("集合参数传递 likes ==> "+ likes);
        return "{'module':'list param'}";
    }

   @RequestMapping("/listParamForJson")
    @ResponseBody
    public String listParamForJson(@RequestBody List<String> likes){
        System.out.println("list common(json)参数传递 list ==> "+likes);
        return "{'module':'list common for json param'}";
    }

@RequestMapping("/pojoParamForJson")
    @ResponseBody
    public String pojoParamForJson(@RequestBody User user){
        System.out.println("pojo(json)参数传递 user ==> "+user);
        return "{'module':'pojo for json param'}";
    }

@RequestMapping("/listPojoParamForJson")
    @ResponseBody

        System.out.println("list pojo(json)参数传递 list ==> "+list);
        return "{'module':'list pojo for json param'}";
    }
