Question

我的实体中定义了java8 LocalDateTime参数。我已经在wildfly 10中部署了我的jax-rs webapp。

当我进行REST调用时，我得到以下异常;

Caused by: java.time.format.DateTimeParseException: Text '2016-06-03T00:38:48.043Z' could not be parsed, unparsed text found at index 23

我在ObjectMapper中注册了JavaTimeModule;

@Provider
public class LocalDateTimeConverterProvider implements ContextResolver<ObjectMapper>, ParamConverterProvider {

    private final LocalDateTimeConverter converter = new LocalDateTimeConverter();

    private final ObjectMapper mapper;

    public LocalDateTimeConverterProvider() {
        mapper = new ObjectMapper();
        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        mapper.registerModule(new JavaTimeModule());


    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        return mapper;
    }

为什么我会遇到异常？ Java8 JavaTimeModule提供的默认序列化器不起作用吗？

使用ISO_DATE_TIME格式注册本地日期时间deserilizer，以允许本地日期时间接受时区。

javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ISO_DATE_TIME)
