Java 接口接收时间

一、添加注解

在实体类属性上加如下注解

// 后台返回数据到前端的数据格式
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
 
// 前台传递参数到后台的数据格式
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")

二、添加yml配置

spring:
  jackson:
    ## 格式为yyyy-MM-dd HH:mm:ss
      date-format: yyyy-MM-dd HH:mm:ss
      ## 定时区，解决8小时的时间差问题
      time-zone: GMT+8

三、全局配置通过Spring

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import java.text.SimpleDateFormat;
import java.util.List;
 
@Configuration
public class MyWebMvcConfigurer implements WebMvcConfigurer {
 
    @Override
    public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
        MappingJackson2HttpMessageConverter jackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper objectMapper = jackson2HttpMessageConverter.getObjectMapper();
        objectMapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
        SimpleModule simpleModule = new SimpleModule();
        objectMapper.registerModule(simpleModule);
        jackson2HttpMessageConverter.setObjectMapper(objectMapper);
        converters.add(0, jackson2HttpMessageConverter);
    }
    
}
