java springboot 自定义异常

  • 自定义返回result
public class CustomResult {      /**      * 状态响应码      */     private String  code;      /**      * 响应信息      */     private String message;      /**      * 响应数据      */     @JsonInclude(JsonInclude.Include.NON_NULL)     private Object data;      /**      * 数据总数      */     @JsonInclude(JsonInclude.Include.NON_NULL)     private Long totalCount;      public CustomResult setCode(CustomResultCode customResultCode) {         this.code = customResultCode.code();         return this;     }      public String getCode() {         return code;     }      public String getMessage() {         return message;     }      public CustomResult setMessage(String message) {         this.message = message;         return this;     }      public Object getData() {         return data;     }      public CustomResult setData(Object data) {         this.data = data;         return this;     }      public Long getTotalCount() { return totalCount;}      public CustomResult setTotalCount(Long totalCount) {         this.totalCount = totalCount;         return this;     }  }
  • 自定义错误code
public enum CustomResultCode {     Custom_SUCCESS("1"), //成功     Custom_Fail("0"); // 失败      private final String code;      CustomResultCode(String code) {         this.code = code;     }      public String code() {         return code;     } }
  • 测试
@RequestMapping("test-custom-exception")     public void testCustomException() {         throw new CustomException("自定义错误");     }
  • 结果
{"code":"0","message":"自定义错误"}
