SpringBoot整合SSM之日期类型转换

这里我用的是一个工具类：

package cn.leon.util;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class JsonDateSerializer extends JsonSerializer<Date> {
    private SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    @Override
    public void serialize(Date date, JsonGenerator gen, SerializerProvider provider)
            throws IOException, JsonProcessingException {
        String value = dateFormat.format(date);
        gen.writeString(value);
    }
}

最后在实体类上需要转换的属性加上注解：

   @DateTimeFormat(pattern = "yyyy-MM-dd hh:mm:ss")
    @JsonSerialize(using = JsonDateSerializer.class)
    private Date monitorTime;
