Hymanson date-format for OffsetDateTime in Spring Boot
提问by Dave
I'm trying to output an OffsetDateTime from my Spring application, and have in my application.properties these properties:
我试图从我的 Spring 应用程序输出一个 OffsetDateTime，并在我的 application.properties 中有这些属性：
spring.Hymanson.serialization.WRITE_DATES_AS_TIMESTAMPS=false
spring.Hymanson.date-format=yyyy-MM-dd'T'HH:mm
However when the date is returned it is formatted as
但是，当返回日期时，它的格式为
"2017-01-30T16:55:00Z"
How should I correctly configure the format for the date in my Spring application?
我应该如何正确配置 Spring 应用程序中的日期格式？

So I've managed to figure out a solution, but if you have an alternative please post it.
所以我设法找到了一个解决方案，但如果你有替代方案，请发布它。
I ended up creating a new primary ObjectMapperbean, and registering a new module with a custom serializer for OffsetDateTime. I'm able to set my own date format in here, using java.time.format.DateTimeFormatter. I also had to register the JavaTimeModulewith my mapper.
我最终创建了一个新的主ObjectMapperbean，并使用自定义序列化程序为OffsetDateTime. 我可以在这里设置我自己的日期格式，使用java.time.format.DateTimeFormatter. 我还必须向JavaTimeModule我的映射器注册。
@Configuration
public class HymansonOffsetDateTimeMapper{
@Primary
@Bean
public ObjectMapper objectMapper() {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new JavaTimeModule());
SimpleModule simpleModule = new SimpleModule();
simpleModule.addSerializer(OffsetDateTime.class, new JsonSerializer<OffsetDateTime>() {
@Override
public void serialize(OffsetDateTime offsetDateTime, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException, JsonProcessingException {
jsonGenerator.writeString(DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(offsetDateTime));
}
});
objectMapper.registerModule(simpleModule);
return objectMapper;
}
}

The spring property doesn't work for me as well. Setting the property to ObjectMapperworks for me though.
spring 属性也不适用于我。不过，将属性设置ObjectMapper为对我有用。
objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

Adding a dependency on Hymanson-modules-java8 worked for me (Hymanson-datatype-jsr310 is deprecated)
添加对 Hymanson-modules-java8 的依赖对我有用（不推荐使用 Hymanson-datatype-jsr310）
<!-- deserialize Java 8 date time types e.g OffsetDateTime -->
<dependency>
<groupId>com.fasterxml.Hymanson.module</groupId>
<artifactId>Hymanson-modules-java8</artifactId>
</dependency>
I also needed to add this for it to work:
我还需要添加它以使其工作：
om.registerModule(new JavaTimeModule());
No need for the write-dates-as-timestamps=false or om.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS) - that is applicable for Java "Date" object.
不需要 write-dates-as-timestamps=false 或 om.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS) - 适用于 Java“日期”对象。
I used this annotation:
我使用了这个注释：
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSXXX")
and get output like this:
并得到这样的输出：
"timestamp":"2020-04-23T08:00:00.000-06:00"
“时间戳”：“2020-04-23T08:00:00.000-06:00”

- Add Hymanson-datatype-jsr310 to your dependencies
Add to application.properties:
spring.Hymanson.serialization.write-dates-as-timestamps=false
- 将 Hymanson-datatype-jsr310 添加到您的依赖项
添加到 application.properties：
spring.Hymanson.serialization.write-dates-as-timestamps=false
You will get:
你会得到：
"lastUpdated": "2017-07-16T19:17:57.689Z"

Have you tried put @JsonFormat(pattern="dd/MM/yyyy HH:mm:ss Z")before your field?
你有没有试过放在@JsonFormat(pattern="dd/MM/yyyy HH:mm:ss Z")你的领域之前？
@JsonProperty("timestamp")
@JsonFormat(pattern="yyyy-MM-dd'T'HH:mm")
private OffsetDateTime timestamp;
I guess you will get:
我想你会得到：
2017-01-30'T'16:55
