java返回数据的ResponseEntity

1.ResponseEntity实体类(对HashMap的封装)

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

package com.kexin.common.util;   import java.util.HashMap;   public class ResponseEntity extends HashMap<String, Object> {       public static ResponseEntity success(String message){         ResponseEntity response = new ResponseEntity();         response.setSuccess(Boolean.TRUE);         response.setMessage(message);         return response;     }       public static ResponseEntity failure(String message){         ResponseEntity response = new ResponseEntity();         response.setSuccess(Boolean.FALSE);         response.setMessage(message);         return response;     }       public ResponseEntity setSuccess(Boolean success) {         if (success != null) put("success", success);         return this;     }       public ResponseEntity setMessage(String message) {         if (message != null) put("message", message);         return this;     }       public ResponseEntity setAny(String key, Object value) {         if (key != null && value != null) put(key, value);         return this;     } }

 2.返回调用eg

 

?

1 2 3 4 5 6 7 8 9

return ResponseEntity.failure("验证码不能为空");   return ResponseEntity.success("操作成功");      ResponseEntity responseEntity = new ResponseEntity();  responseEntity.setSuccess(Boolean.TRUE);  responseEntity.setAny("url","index");  return responseEntity;
