解决前端获取后端返回的日期类型数据少一天的问题

1. application.yml中进行以下配置

spring: 
  jackson:
    date-format: yyyy-MM-dd
    time-zone: GMT+8

2. 使用注解

@JsonFormat(pattern = "yyyy-MM-dd",time-zone="GMT+8")
private Date createDate;

使用JsonFormat可能会出现以下错误信息

Field error in object 'user' on field 'createDate': rejected value [2019-09-22]; 
codes [typeMismatch.user.createDate,typeMismatch.createDate,typeMismatch.java.util.Date,typeMismatch];
arguments [org.springframework.context.support.DefaultMessageSourceResolvable: 
codes [user.createDate,createDate]; arguments []; default message [createDate]]; 
default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'createDate'; 
nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@com.fasterxml.jackson.annotation.JsonFormat java.util.Date] for value '2019-09-22'; 
nested exception is java.lang.IllegalArgumentException]]

解决：使用DateTimeFormat注解指定日期格式, 然后再配置yml文件解决时区问题

@DateTimeFormat(pattern = "yyyy-MM-dd")
private Date createDate;
