{ "updatorCode": "00013838", "updTm": 1694762024000, "checkTools": "OldApp" }此json转为java对象如何处理，其中updTm为Date类型

可以使用Jackson库将该json转为java对象，其中updTm需要使用@JsonFormat注解指定日期格式。具体代码如下：

import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.util.Date;

public class JsonToObject {
    public static void main(String[] args) throws Exception {
        String json = "{\"updatorCode\": \"00013838\", \"updTm\": 1694762024000, \"checkTools\": \"OldApp\"}";

        ObjectMapper objectMapper = new ObjectMapper();
        MyObject myObject = objectMapper.readValue(json, MyObject.class);

        System.out.println(myObject);
    }

    static class MyObject {
        @JsonProperty("updatorCode")
        private String updatorCode;

        @JsonProperty("updTm")
        @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
        private Date updTm;

        @JsonProperty("checkTools")
        private String checkTools;

        // getter and setter
    }
}
