通过实体类转换JSON

• RootEntity

      ` 
        package com.ithelei;
        import java.util.List;
    
        public class RootEntity {
    
        private String errorCode;
        private String errorMsg;
        private List<UserEntity> data;
    
        public String getErrorCode() {
            return errorCode;
        }
    
        public void setErrorCode(String errorCode) {
            this.errorCode = errorCode;
        }
    
        public String getErrorMsg() {
            return errorMsg;
        }
    
        public void setErrorMsg(String errorMsg) {
            this.errorMsg = errorMsg;
        }
    
        public List<UserEntity> getData() {
            return data;
        }
    
        public void setData(List<UserEntity> data) {
            this.data = data;
        }
    
        @Override
        public String toString() {
            return "RootEntity [errorCode=" + errorCode + ", errorMsg=" + errorMsg + ", data=" + data + "]";
        }
    
        }
        `
  

• UserEntity

          `package com.ithelei;
    
         public class UserEntity {
    
        private String position;
        private String userName;
        private String webAddres;
    
        public String getPosition() {
            return position;
        }
    
        public void setPosition(String position) {
            this.position = position;
        }
    
        public String getUserName() {
            return userName;
        }
    
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public String getWebAddres() {
            return webAddres;
        }
    
        public void setWebAddres(String webAddres) {
            this.webAddres = webAddres;
        }
    
        @Override
        public String toString() {
            return "UserEntity [position=" + position + ", userName=" + userName + ", webAddres=" + webAddres + "]";
        }
    
      }
      `
  

• JSONTest

        `public static void main(String[] args) { 
         setBeanToJSON(); 
         }
         `

         `     
          public  static void setBeanToJSON() {
    
            RootEntity rootEntity = new RootEntity();
            rootEntity.setErrorCode("0");
            rootEntity.setErrorMsg("调用接口成功");
            
            List<UserEntity> data = new ArrayList<UserEntity>();
            
            UserEntity userEntity = new UserEntity();
            userEntity.setPosition("技术网站负责人");
            userEntity.setUserName("贺雷");
            userEntity.setWebAddres("www.ithelei.com");
            data.add(userEntity);//集合中装对象
            
            rootEntity.setData(data);
            System.out.println(new JSONObject().toJSONString(rootEntity));
        }`
