时间Date格式转换为json后出现的问题处理

在date形数据转换成json后或出现如下情况：

[{"CreateTime":{"date":4,"day":0,"hours":23,"minutes":58,"month":5,"seconds":9,"time":1496591889969,"timezoneOffset":-480,"year":117},"userName":"Woods"}]

这样前端不好处理

处理方法：

package com.couponMgmt.core.utils;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import java.util.Locale;
    
    import net.sf.json.JsonConfig;
    import net.sf.json.processors.JsonValueProcessor;
    
    public class JsonDateValueProcessor implements JsonValueProcessor {
        private String format ="yyyy-MM-dd HH:mm:ss";  
    
        public JsonDateValueProcessor() {  
            super();  
        }  
    
        public JsonDateValueProcessor(String format) {  
            super();  
            this.format = format;  
        }  
    
        public Object processArrayValue(Object paramObject, JsonConfig paramJsonConfig) {  
            return process(paramObject);  
        }  
    
        public Object processObjectValue(String paramString, Object paramObject,  JsonConfig paramJsonConfig) {  
            return process(paramObject);  
        }  
    
        private Object process(Object value){  
            if(value instanceof Date){    
                SimpleDateFormat sdf = new SimpleDateFormat(format,Locale.CHINA);    
                return sdf.format(value);  
            }    
            return value == null ? "" : value.toString();    
        }  
    }

测试一下

package couponMgmt;
    
    import java.util.ArrayList;
    import java.util.Date;
    import java.util.List;
    
    import com.couponMgmt.core.utils.JsonDateValueProcessor;
    
    import net.sf.json.JSONArray;
    import net.sf.json.JsonConfig;
    
    public class JSONTEST {
    
        public static void main(String[] args) {
    
            List<UserInfo> list = new ArrayList<>();
            UserInfo userInfo = new UserInfo();
            userInfo.setUserName("Woods");
            userInfo.setEnrollTime(new Date());
            list.add(userInfo);
            JsonConfig config = new JsonConfig();
            config.registerJsonValueProcessor(Date.class, new JsonDateValueProcessor());
            JSONArray jsonArray2 = JSONArray.fromObject(list, config);
            System.out.println(jsonArray2);
        }
    
    }

返回结果：

[
        {
            "enrollTime": "2017-06-05 00:00:12",
            "userName": "Woods"
        }
    ]
