本文详细介绍了如何在SpringBoot应用中使用Postman进行不同类型的请求参数处理，包括简单的字符串和整型参数、实体类参数如User，复杂实体包含Address属性，数组和集合参数，日期参数以及JSON格式的参数。同时，对比了原始的HttpServletRequest方式与SpringBoot注解方式的不同。

一、概述

二、postman

三、请求-简单参数&实体参数

1、原始方式

package com.itheima.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

/**
 * Description:
 * date: 2023/4/17 21:02
 *
 * @since JDK 11
 */
@RestController
public class RequestController {
// 原方式：这种方式比较繁琐，只需要了解，下面将用springboot方法
   @RequestMapping("/simpleParam")
   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";
   }
}

2、springboot方式

package com.itheima.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

/**
 * Description:
 * date: 2023/4/17 21:02
 *
 * @since JDK 11
 */
@RestController
public class RequestController {
// springboot方式
   @RequestMapping("/simpleParam")
   public String simpleParam(String name,Integer age){
      System.out.println(name+"："+age);
      return "ok";
   }
}

post请求

四、简单实体参数

pojo下的User.java

package com.itheima.pojo;

/**
 * Description:
 * date: 2023/4/17 21:43
 *
 * @since JDK 11
 */
public class User {
   private String name;
   private Integer age;

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

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

五、复杂实体参数

package com.itheima.pojo;

/**
 * Description:
 * date: 2023/4/17 21:43
 *
 * @since JDK 11
 */
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 +
            '}';
   }
}
