二、IDEA内置功能方案
2.1 HTTP Client - 内置接口测试工具
创建HTTP请求文件
# 方法1:通过菜单创建
右键项目 → New → HTTP Request
命名为: api-test.http
# 方法2:快捷键创建
Ctrl + Alt + Shift + Insert (Windows/Linux)
Cmd + Option + N (macOS)
# 方法3:直接创建文件
在项目中创建 .http 或 .rest 后缀的文件
例如:user-api.http
HTTP请求文件示例
### GET 请求示例
GET http://localhost:8080/api/users/1
Accept: application/json
Authorization: Bearer {{auth_token}}
### POST 请求示例
POST http://localhost:8080/api/users
Content-Type: application/json
{
"username": "testuser",
"email": "test@example.com",
"password": "password123"
}
### PUT 请求示例
PUT http://localhost:8080/api/users/1
Content-Type: application/json
{
"username": "updateduser",
"email": "updated@example.com"
}
### DELETE 请求示例
DELETE http://localhost:8080/api/users/1
Authorization: Bearer {{auth_token}}
### 带查询参数
GET http://localhost:8080/api/users?status=active&page=1&size=10
### 文件上传
POST http://localhost:8080/api/upload
Content-Type: multipart/form-data; boundary=WebAppBoundary
--WebAppBoundary
Content-Disposition: form-data; name="file"; filename="test.jpg"
Content-Type: image/jpeg
< ./test.jpg
--WebAppBoundary--

5.3 代码注解最佳实践
// 1. 统一响应格式
@Schema(description = "统一响应格式")
public class ApiResponse<T> {
@Schema(description = "状态码", example = "200")
private Integer code;
@Schema(description = "消息", example = "success")
private String message;
@Schema(description = "数据")
private T data;
@Schema(description = "时间戳", example = "1640995200000")
private Long timestamp;
// 构造方法、静态工厂方法...
public static <T> ApiResponse<T> success(T data) {
ApiResponse<T> response = new ApiResponse<>();
response.setCode(200);
response.setMessage("success");
response.setData(data);
response.setTimestamp(System.currentTimeMillis());
return response;
}
}
// 2. 分页响应
@Schema(description = "分页响应")
public class PageResponse<T> {
@Schema(description = "数据列表")
private List<T> content;
@Schema(description = "总记录数", example = "100")
private Long total;
@Schema(description = "页码", example = "1")
private Integer page;
@Schema(description = "每页大小", example = "10")
private Integer size;
@Schema(description = "总页数", example = "10")
private Integer totalPages;
// getters and setters...
}
// 3. 全局异常处理
@RestControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(ResourceNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
@ResponseBody
public ApiResponse<Object> handleNotFound(ResourceNotFoundException e) {
return ApiResponse.error(404, e.getMessage());
}
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ResponseBody
public ApiResponse<Object> handleValidation(MethodArgumentNotValidException e) {
Map<String, String> errors = new HashMap<>();
e.getBindingResult().getFieldErrors().forEach(error ->
errors.put(error.getField(), error.getDefaultMessage())
);
return ApiResponse.error(400, "参数验证失败", errors);
}
}
// 4. 安全配置
@Configuration
@EnableWebSecurity
public class SecurityConfig {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.csrf().disable()
.authorizeHttpRequests(authz -> authz
.requestMatchers("/api/public/**").permitAll()
.requestMatchers("/swagger-ui/**", "/v3/api-docs/**").permitAll()
.anyRequest().authenticated()
)
.httpBasic();
return http.build();
}
}

1. 检查Content-Type头
2. 确保请求体格式正确
3. 使用Response Handler:
GET http://api.example.com/users
Accept: application/json
> {%
client.test("Status code is 200", function() {
client.assert(response.status === 200, "Response status is not 200");
});
%}
