一:ObjectMapper mapper =new ObjectMapper().setVisibility(JsonMethod.FIELD,Visibility.ANY); mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); 二:ObjectMapperobjectMapper=newObjectMapper(); mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); ObjectMapper可以实现对象...

微服务中从其他服务获取过来的对象,如果从Object强转为自定义的类型会报错,利用ObjectMapper转换。 ObjectMapper mapper =newObjectMapper(); DefaultResponse defaultResponse=proxy.getData(); List<Resource> resources = (<Resource>) defaultResponse.getData();//这里的场景是:data是一个Object类型的,但是它其实是一...

mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); 第二种方式: ObjectMapper objectMapper = new ObjectMapper(); mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false); 2.3.3 在转换的过程中,有可能有的属性被设成空就不序列化等的需求,可以在类的属性上或直接在类...
