Postman接口测试工具，提高SpringBoot开发效率-CSDN博客

工具—postman

postman是一款功能强大的网页调试与发送网页HTTP请求的Chrome插件

⭐作用

常用于进行接口测试

️‍安装

我把安装包传到网盘里面了点击exe文件就可以下载需要的同学请自取

链接

创建工作空间

点击CTRL+S进行保存
这样子即使我们关了也能够访问

简单参数

⭐原始方式

在原始的web程序中获取请求参数需要通过HttpServletRequest对象手动获取

我们建立springboot项目输入下面的代码

import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class RequestController  {
    //原始方法
    //设置注解指定请求路径
    @RequestMapping("/simpleParam")
    public String simpleParam(HttpServletRequest request){
        //获取请求参数
        String name=request.getParameter("name");
        String ageStr=request.getParameter("age");

        int age=Integer.parseInt(ageStr);
        System.out.println(name+":"+age);
        return "OK";
    }
}

运行

这时候我们打开postman不要终止项目运行
输入http://localhost:8080/simpleParam?name=Tom&age=10
然后点击send

⭐SpringBoot方式

只需要保证参数名和变量名相同定义形参即可接收参数

import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class RequestController  {
    //原始方法
    //设置注解指定请求路径
    @RequestMapping("/simpleParam")
    public String simpleParam(String name,Integer age){
        //SpringBoot方式
        System.out.println(name+":"+age);
        return "OK";
    }
}

实体参数

️‍简单实体参数

请求参数名与形参对象属性名相同定义POJO接收即可

⭐代码实现

创建类User.java

public class User {
    private String name;
    private Integer 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 +
                '}';
    }
}

创建类RequestController.Java

import com.example.springbootwebreqresp.pojo.User;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class RequestController  {

    //实体参数
    //设置注解指定请求路径
    @RequestMapping("/simplePojo")
    public String simplePojo(User user){
        System.out.println(user);
        return "OK";
    }
}

️‍复杂实体参数

请求参数名与形参对象属性名相同安装对象层次结构关系即可接收嵌套POJO属性参数

⭐代码实现

创建类User.java

package com.example.springbootwebreqresp.pojo;

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 +
                '}';
    }
}

创建类Address.java

package com.example.springbootwebreqresp.pojo;

public class Address {
    private String province;
    private String 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;
    }

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

创建类RequestController.Java

package com.example.springbootwebreqresp.controller;

import com.example.springbootwebreqresp.pojo.User;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


    @RequestMapping("/complexPojo")
    public String complexPojo(User user){
        System.out.println(user);
        return "OK";
    }
}

数组集合参数

⭐使用数组来接收

请求参数名与形参数组名相同且请求参数为多个定义数组类型形参即可接收参数

package com.example.springbootwebreqresp.controller;

import com.example.springbootwebreqresp.pojo.User;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.lang.reflect.Array;
import java.util.Arrays;


@RestController
public class RequestController  {
    @RequestMapping("/arrayParam")
    public String arrayParam(String[] hobby){
        System.out.println(Arrays.toString(hobby));
        return "OK";
    }
}

⭐使用集合来接收

请求参数名与形参集合名称相同且请求参数为多个@RequestParam绑定参数关系

package com.example.springbootwebreqresp.controller;

import com.example.springbootwebreqresp.pojo.User;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.lang.reflect.Array;
import java.util.Arrays;
import java.util.List;


@RestController
public class RequestController  {
    @RequestMapping("/arrayParam")
    public String arrayParam(@RequestParam List<String>hobby){
        System.out.println(hobby);
        return "OK";
    }
}

小结

日期参数

使用@DateTimeFormat注解完成日期参数格式转换

路径参数
