新建swagger配置

新建前后端响应工具类
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
/**
* @author ie
* @ 日期 2019-10-25 14:24
*/
@Data
public class Result<T> {
@ApiModelProperty(value = "状态值")
private int code;
@ApiModelProperty(value = "提示信息")
private String message;
@ApiModelProperty(value = "结果")
private T payload;
private Result<T> code(int code) {
this.code = code;
return this;
}
private Result<T> message(String message) {
this.message = message;
return this;
}
private Result<T> payload(T payload) {
this.payload = payload;
return this;
}
public static <T> Result<T> ok() {
return new Result<T>().code(ResultCode.SUCCESS.getCode()).message(ResultCode.SUCCESS.getMessage()).payload(null);
}
public static <T> Result<T> ok(T payLoad) {
return new Result<T>().code(ResultCode.SUCCESS.getCode()).message(ResultCode.SUCCESS.getMessage()).payload(payLoad);
}
public static <T> Result<T> fail() {
return new Result<T>().code(ResultCode.FAIL.getCode()).message(ResultCode.FAIL.getMessage()).payload(null);
}
public static <T> Result<T> result(int code, String message, T payload) {
return new Result<T>().code(code).message(message).payload(payload);
}
}
状态码
@Getter
public enum ResultCode {
//成功
SUCCESS(20000, "成功"),
//失败
FAIL(40000, "失败"),
//未认证（签名错误）
UNAUTHORIZED(40001, "未认证（签名错误）"),
//接口不存在
NOT_FOUND(40004, "接口不存在"),
//服务器内部错误
INTERNAL_SERVER_ERROR(50000, "服务器内部错误"),
//TOKEN已过期
TOKEN_INVAILD(10001, "TOKEN已过期"),
//TOKEN无效
TOKEN_NOTFOUND(10002, "TOKEN无效");
private final int code;
private final String message;
ResultCode(int code, String message) {
this.code = code;
this.message = message;
}
}
Controller 层使用
@GetMapping(value = "/detail")
@ApiOperation(value = "根据id查询用户")
public Result<User> detail(@RequestParam("userId") Long userId) {
log.info("根据userId查询用户信息【{}】", userId);
User user = userService.findByUserId(userId);
log.info("用户信息【{}】", user.toString());
return Result.ok(user);
}
PageInfo 封装
