<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.12.5</version>
</dependency>

import com.fasterxml.jackson.annotation.JsonFormat;
import java.util.Date;

public class MyClass {
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date date;

    // 其他属性和方法...
}

import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.Date;

public class Main {
    public static void main(String[] args) throws Exception {
        MyClass myObject = new MyClass();
        myObject.setDate(new Date());

        ObjectMapper mapper = new ObjectMapper();
        String json = mapper.writeValueAsString(myObject);

        System.out.println(json);
    }
}
