[BUG]2.0.14定制java.sql.Date, java.sql.Time, java.util.Date序列化格式失效

[leonchen83]

问题描述

简要描述您碰到的问题。

环境信息

请填写以下信息：

• OS信息： win10
• JDK信息： jdk11
• 版本信息：2.0.14

重现步骤

如何操作可以重现该问题：

public class Main {
	public static void main(String[] args) {
		JSON.register(java.sql.Date.class, new ObjectWriter<java.sql.Date>() {
			@Override
			public void write(JSONWriter jsonWriter, Object object, Object fieldName, Type fieldType, long features) {
				Date v = Objects.cast(object);
				jsonWriter.writeString(String.valueOf(v.getTime()));
			}
		});
		
		Test t = new Test();
		t.setDate(new Date(System.currentTimeMillis()));
		
		String s = JSON.toJSONString(t);
		System.out.println(s);
	}
	
	static class Test {
		java.sql.Date date;

		public Date getDate() {
			return date;
		}

		public void setDate(Date date) {
			this.date = date;
		}
	}
}

输出

{"date":"2022-09-19 11:23:01.586"}

期待输出

{"date":"1663557803850"}

java.sql.Time，java.util.Date也是如此

问题已修复，请帮忙用2.0.15-SNAPSHOT验证，2.0.15版本预计在10月7日前发布

你也可以用一下的代码，更简洁：

   @Test
    public void test1() {
        JSON.mixIn(Date.class, DateMixin.class);

        long millis = 1663595616049L;
        Bean1 t = new Bean1();
        t.setDate(new Date(millis));

        String s = JSON.toJSONString(t);
        assertEquals("{\"date\":1663595616049}", s);
    }

    @JSONType(format = "millis")
    public static class DateMixin {
    }

    static class Bean1 {
        Date date;

        public Date getDate() {
            return date;
        }

        public void setDate(Date date) {
            this.date = date;
        }
    }

@wenshao java.util.Date仍然没有显示时间戳

import java.lang.reflect.Type;
import java.util.Date;

import com.alibaba.fastjson2.JSONWriter;
import com.alibaba.fastjson2.writer.ObjectWriter;

import cn.nextop.gadget.core.util.Objects;

/**

public class Main {
	public static void main(String[] args) {
		JSON.register(java.util.Date.class, new ObjectWriter<java.util.Date>() {
			@Override
			public void write(JSONWriter jsonWriter, Object object, Object fieldName, Type fieldType, long features) {
				Date v = Objects.cast(object);
				jsonWriter.writeString(String.valueOf(v.getTime()));
			}
		});
		
		Test t = new Test();
		t.setDate(new Date(System.currentTimeMillis()));
		
		String s = JSON.toJSONString(t);
		System.out.println(s);
	}
	
	static class Test {
		java.util.Date date;

		public Date getDate() {
			return date;
		}

		public void setDate(Date date) {
			this.date = date;
		}
	}
}
