一、准备基础环境

创建SysUserController

/**
* (SysUser)表控制层
*/
@RestController
@RequestMapping("sysUser")
@RequiredArgsConstructor
public class SysUserController {
  private final SysUserService sysUserService;
  /**
   * 通过id查询
   *
   * @param id 主键
   * @return 单条数据
   */
  @GetMapping("{id}")
  public SysUser getById(@PathVariable Serializable id) {
      return this.sysUserService.getById(id);
  }
  /**
   * 新增数据
   *
   * @param sysUser 实体对象
   * @return 新增结果
   */
  @PostMapping
  public boolean insert(@RequestBody SysUser sysUser) {
      return this.sysUserService.save(sysUser);
  }
}

创建SysUser实体类对象

/**
* (SysUser)表实体类
*/
@Data
public class SysUser implements Serializable {
  /*主键ID*/
  private Long id;
  /*姓名*/
  private String name;
  /*年龄*/
  private Integer age;
  /*邮箱*/
  private String email;
}

创建sys_user数据表

mysql> select * from sys_user;
+-----+--------+-----+--------------------+
| id  | name   | age | email              |
+-----+--------+-----+--------------------+
|   1 | Jone   |  18 | test1@baomidou.com |
|   2 | Jack   |  20 | test2@baomidou.com |
|   3 | Tom    |  28 | test3@baomidou.com |
|   4 | Sandy  |  21 | test4@baomidou.com |
|   5 | Billie |  24 | test5@baomidou.com |
+-----+--------+-----+--------------------+
6 rows in set (0.02 sec)

二、使用`crul`命令

使用命令，向SysUserController#getById()方法，发送GET请求：

curl http://localhost:8080/sysUser/1

/* 通过id查询 */
@GetMapping("{id}")
public SysUser getById(@PathVariable Serializable id) {
  return this.sysUserService.getById(id);
}

11475@greamrod-pc-company MINGW64 ~/Desktop/curl
$ curl http://localhost:8080/sysUser/1
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                               Dload  Upload   Total   Spent    Left  Speed
100    60    0    60    0     0   7500      0 --:--:-- --:--:-- --:--:--  7500
{"id":1,"name":"Jone","age":18,"email":"test1@baomidou.com"}

发送POST请求，并携带JSON数据，来新增一条数据记录：

curl -X POST "http://localhost:8080/sysUser" \
-d "{\"id\":200,\"name\":\"Jone\",\"age\":18,\"email\":\"Jone@baomidou.com\"}" \
-H  "Accept:*/*" \
-H  "Content-Type:application/json"

/* 新增数据 */
@PostMapping
public boolean insert(@RequestBody SysUser sysUser) {
  return this.sysUserService.save(sysUser);
}

11475@greamrod-pc-company MINGW64 ~/Desktop/curl
$ curl -X POST "http://localhost:8080/sysUser" \
> -d "{\"id\":200,\"name\":\"Jone\",\"age\":18,\"email\":\"Jone@baomidou.com\"}" \
> -H  "Accept:*/*" \
> -H  "Content-Type:application/json"
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                               Dload  Upload   Total   Spent    Left  Speed
100    65    0     4  100    61    363   5545 --:--:-- --:--:-- --:--:--  6500
true

在curl目录下，创建一个person.json文件，内容如下： ```bash 11475@greamrod-pc-company MINGW64 ~/Desktop/curl $ pwd /c/Users/11475/Desktop/curl

11475@greamrod-pc-company MINGW64 ~/Desktop/curl $ ls -l total 1 -rw-r—r— 1 11475 197609 83 6月 8 15:13 person.json

11475@greamrod-pc-company MINGW64 ~/Desktop/curl $ cat person.json { “id”:200, “name”: “Jone”, “age”: 18, “email”: “test1@baomidou.com” }


- 发送`POST`请求，并携带一个`person.json`文件，来新增一条数据记录：<br />
> 注意：发送命令时，将目录切换到`person.json`文件所在的目录
```bash
curl -v -X POST -d @person.json http://localhost:8080/sysUser \
--header "Accept: application/json, application/*+json" \
--header "Content-Type:application/json"

/* 新增数据 */
@PostMapping
public boolean insert(@RequestBody SysUser sysUser) {
    return this.sysUserService.save(sysUser);
}

11475@greamrod-pc-company MINGW64 ~/Desktop/curl
$ curl -v -X POST -d @person.json http://localhost:8080/sysUser \
> --header "Accept: application/json, application/*+json" \
> --header "Content-Type:application/json"
Note: Unnecessary use of -X or --request, POST is already inferred.

发送GET请求，并携带参数，来新增一条数据记录：

curl -X GET "http://localhost:8080/sysUser?age=30&email=greamrod@qq.com&id=1001&name=greamrod-lost" \

  return this.sysUserService.save(sysUser);
}

--data "age=20&email=java@qq.com&id=2001&name=java" \
-H  "Accept:*/*" \

@PostMapping
public boolean insert(@RequestParam("id") Long id, @RequestParam("name") String name, @RequestParam("age") Integer age,
                    @RequestParam(value = "email", required = false) String email) {
  SysUser sysUser = new SysUser(id, name, age, email);
