创建common包，定义一个枚举类：

package com.mincheng.organization.common; import lombok.Getter; @Getter public enum ResultCode {

SUCCESS(true),

FAIL(false, 500, " 服务器出错

"),

/* 参数错误：1000 - 1999 */

/* 用户错误：2000 - 2999 */

/* 接口异常：

3000 - 3999 */;

private Boolean success;

private Integer errorCode;

private String errorMessage;

ResultCode(Boolean success) {

this.success = success;   }

ResultCode(Boolean success, Integer errorCode, String errorMessage) {

this.success = success;

this.errorCode = errorCode;

this.errorMessage = errorMessage;

} } 定义apiResult返回类：

package com.mincheng.organization.common; import lombok.Getter; import lombok.Setter; import lombok.extern.slf4j.Slf4j; import java.io.Serializable; @Slf4j @Getter @Setter public class ApiResult<T> implements Serializable {

private static final long serialVersionUID = 5469544233990086588L;

protected Boolean success;

protected T result;

protected Integer errorCode;

protected String errorMessage;

public ApiResult() {   }

public ApiResult(Boolean success, T data) {

this.success = success;

this.result = data;   }

public ApiResult(Boolean success, Integer errorCode, String errorMessage) {

this.success = success;

this.errorCode = errorCode;

this.errorMessage = errorMessage;

this.result = null;   }

public static <T> ApiResult success(ResultCode resultCode, T data) {

return new ApiResult(resultCode.getSuccess(), data);   }

public static <T> ApiResult fail(ResultCode resultCode) {

return new ApiResult(resultCode.getSuccess(), resultCode.getErrorCode(), resultCode.getErrorMessage());

} } 修改controller类，进行一层包装；

import com.mincheng.organization.service.department.DepartmentService; import io.swagger.v3.oas.annotations.Operation; import io.swagger.v3.oas.annotations.tags.Tag; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; @RestController @RequestMapping(value = "/department") @Tag(name = "department", description = " 部门表

") public class DepartmentController {

@Resource

private DepartmentService departmentService;

@PostMapping(value = "/list")

@Operation(method = "post", description = " 列表

")

public ApiResult<Department> list(@RequestBody Department department) {

return ApiResult.success(ResultCode.SUCCESS, departmentService.list(department));   }

@GetMapping(value = "/detail")

@Operation(method = "get", description = " 详情

")

public ApiResult<Department> detail(@RequestParam String id) {

return ApiResult.success(ResultCode.SUCCESS, departmentService.detail(id));

} }
