java - 如何使用 Moxy 将 json 字符串转换为 LocalDateTime

Question

我正在使用球衣实现 REST 服务（POST 方法），并且我在请求对象中有 LocalDateTime 字段。当我使用邮递员发送 json 请求时，请求对象中的 LocalDateTime 字段被设置为空。

我通过设置 LocalDateTime 值并在响应中发送它来测试序列化。它工作正常。

下面是我的代码 pom.xml 示例请求和响应。有人可以帮忙解决这个问题吗？

import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;

public class Request {
@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime startDateTime;

@JsonSerialize(using = LocalDateTimeSerializer.class)
@JsonDeserialize(using = LocalDateTimeDeserializer.class)
private LocalDateTime endDateTime;

private String id;
}

//REST API

@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response test(Request request) {
    request.setStartDateTime(LocalDateTime.now());
    return Response.ok().entity(request).build();
}

//上下文解析器

@Provider
public class ObjectMapperContextResolver implements ContextResolver<ObjectMapper> {
private final ObjectMapper MAPPER;

public ObjectMapperContextResolver() {
    MAPPER = new ObjectMapper();
    MAPPER.registerModule(new JavaTimeModule());
    MAPPER.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
}

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