无法构造`java.time.ZonedDateTime`的实例（不存在像默认构造那样的创建者）

正如@PaulSamsotha所指出的，我也需要在客户端注册JacksonJsonProvider：

ClientConfig cc = new DefaultClientConfig();cc.getSingletons().add(ShopApplication.newJacksonJsonProvider());wr = Client.create(cc).resource(Main.base_URI.resolve("products"));

其中包含定制的解决方案：

private static JacksonJsonProvider newJacksonJsonProvider() {  ObjectMapper mapper =      new ObjectMapper()          .registerModule(new ParameterNamesModule())          .registerModule(new Jdk8Module())          .registerModule(new JavaTimeModule()); // new module, NOT JSR310Module  mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);  mapper.setDateFormat(new StdDateFormat());  return new JacksonJsonProvider(mapper);}
