我正在阅读Moxy ignore invalid fields in json的答案,并且该方法与我要尝试执行的操作匹配,因此我决定尝试一下。
@Provider
public class JsonFeature implements Feature {
@Override
public boolean configure(final FeatureContext context) {
final String disableMoxy = CommonProperties.MOXY_JSON_FEATURE_DISABLE +
'.' +
context.getConfiguration().getRuntimeType().name().toLowerCase();
context.property(disableMoxy, true);
return true;
}
}
我创建了一个非常简单的自定义提供程序;
@Provider
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class JsonProvider extends MOXyJsonProvider {
@Override
protected void preWriteTo(Object object, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, Marshaller marshaller)
throws JAXBException {
System.out.println("test");
}
@Override
protected void preReadFrom(Class<Object> type, Type genericType, Annotation[] annotations,
MediaType mediaType, MultivaluedMap<String, String> httpHeaders,
Unmarshaller unmarshaller)
throws JAXBException {
System.out.println("test");
}
}
我都注册了;
register(JsonFeature.class);
register(JsonProvider.class);
然后我用一个简单的GET请求试了一下。
@GET
@Path("test")
public String getTest() {
return new TestObject();
}
我相信这应该可行,但是preWriteTo或preReadFrom都不会被调用。我还缺少其他步骤吗?我该如何射击?
最佳答案
弄清楚了-对于任何偶然发现它的人。
@Provider
public class JsonFeature implements Feature {
@Override
public boolean configure(final FeatureContext context) {
context.property(CommonProperties.MOXY_JSON_FEATURE_DISABLE_SERVER, true);
return true;
}
}
然后像这样扩展可配置的MoxyJsonProvider; @Provider
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class JsonProvider extends ConfigurableMoxyJsonProvider {
@Override
protected void preWriteTo(Object object, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, Marshaller marshaller)
throws JAXBException {
System.out.println("test");
}
@Override
protected void preReadFrom(Class<Object> type, Type genericType, Annotation[] annotations,
MediaType mediaType, MultivaluedMap<String, String> httpHeaders,
Unmarshaller unmarshaller)
throws JAXBException {
System.out.println("test");
}
}
