1.请求响应

        1.安装postman

        2.简单的参数

//原始的请求参数的方法
   
 @RequestMapping("/simoleParam")
    public String simpleParam(HttpServletRequest request){
        String name = request.getParameter("name");
        String ageStr = request.getParameter("age");
        int age = Integer.parseInt(ageStr);
        System.out.println(name+age);
        return "OK";
    }


//基于springboot请求参数
    @RequestMapping("/simpleParam")
    public String simpleParam(String name,Integer age){
        System.out.println(name+":"+age);

        return "ok";
    }

     /*@RequestParam(name = "name",required = false)
        加上注解以后，前段参数可以与接收参数名字不一致
        required默认为true 表示参数不能为空*/
    @RequestMapping("/simpleParam")
    public String simpleParam(@RequestParam(name = "name",required = false) String username, Integer age){
        System.out.println(username+":"+age);
        return "ok";
    }

2.实体参数

    @RequestMapping("/complexPojo")
    public String simpleJoJo(User user){
        System.out.println(user);
        return "获取参数~";
    }

package com.wwl.jojo;

public class User {
    private String name;
    private Integer age;
    private Address address;

    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

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

    public Address getAddress() {
        return address;
    }

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

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

package com.wwl.jojo;

public class Address {
    private String provice;
    public String city;

    public String getProvice() {
        return provice;
    }

    public void setProvice(String provice) {
        this.provice = provice;
    }

    public String getCity() {
        return city;
    }

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

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

3.数组集合参数

    @RequestMapping("/arrayPojo")
    public String arrayPojo(String[] hobby){
        System.out.println(Arrays.toString(hobby));
        return "获取参数~";
    }

集合

    @RequestMapping("/listParam")
    public String listParam(@RequestParam List<String> hobby){
        System.out.println(hobby);
        return "获取参数~";
    }

4.时间参数

@RequestMapping("/timeParam")
public String timeParam(@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") LocalDateTime updateTime){
    System.out.println(updateTime);
    return "ok";
}

5.Json参数

    @RequestMapping("/jsonParam")
    public String jsonParam(@RequestBody User user){
        System.out.println(user);

        return "ok";
    }

6.路径参数

@RequestMapping("/path/{id}/{name}")
public String pathParam(@PathVariable Integer id,@PathVariable String name){
    System.out.println(id+":"+name);
    return "ok";
}

统一响应结果
