How to make default time zone apply in Spring Boot Hymanson Date serialization
提问by codependent
I have configured my Spring Boot application to serialize dates as ISO8601 strings:
我已将 Spring Boot 应用程序配置为将日期序列化为 ISO8601 字符串：
spring:
Hymanson:
serialization:
write-dates-as-timestamps: false
This is what I am getting:
这就是我得到的：
"someDate": "2017-09-11T07:53:27.000+0000"
However my time zone is Europe/Madrid. In fact if I print TimeZone.getDefault()that's what I get.
但是我的时区是欧洲/马德里。事实上，如果我打印TimeZone.getDefault()这就是我得到的。
How can I make Hymanson serialize those datetime values using the actual timezone? GMT+2
如何让 Hymanson 使用实际时区序列化这些日期时间值？格林威治标准时间+2
"someDate": "2017-09-11T09:53:27.000+0200"

我发现自己遇到了同样的问题。就我而言，我的应用程序只有一个时区，然后添加：
spring.Hymanson.time-zone: America/Sao_Paulo
in my application.propertiessolved the problem.
在我application.properties解决了这个问题。

You can set timezone for whole application with adding this to a config class:
您可以通过将其添加到配置类来为整个应用程序设置时区：
@PostConstruct
void started() {
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}

There are 2 solutions for this:
有两种解决方案：
1. Add JSON format annotation
1.添加JSON格式注释
@JsonFormat(shape = JsonFormat.Shape.STRING, timezone = "Asia/Kolkata")
private Date insertionTime;
2. Add Hymanson time zone to properties (spring boot)
2.在属性中添加Hymanson时区（spring boot）
spring.Hymanson.time-zone: America/Sao_Paulo
