quarkus resteasy-jackson empty json 本机结果

Question

测试 quarkus 应用程序，使用我的 rest 端点 /init

已安装的功能：[cdi、resteasy、resteasy-jackson]

我发现当运行 app as java (not native), 然后检查 http://localhost:8080/init

{
"user": {
"username": "u name",
"firstName": "f name",
"lastName": "l name",
"email": null
},
"logoutUrl": "url!!!!"
}

作为本地人，

和运行宁像这样：包-Dnative -f pom.xml

然后运行 ./my-service-1.0-SNAPSHOT-运行ner:

得到空结果： http://localhost:8080/init

{}

Jackson 配置如下：

    @Singleton
public class RegisterCustomModuleCustomizer implements ObjectMapperCustomizer {

    public void customize(final ObjectMapper objectMapper) {
        objectMapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
        objectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    }
}

无一例外。

InitData 像这样定义，作为普通 bean class:

    public class InitData {

        private .. some fields

可能缺少什么？它不应该对 native/java 起作用吗？

更新:

当运行为java时，编译quarkus:dev -f pom.xml:

然后点击：http://localhost:8080/init

Answer 1

@RegisterForReflection（来自 here）是在数据对象上使用的注释，如果您的资源直接 return 该数据对象。

即就我而言：

  @GET
    public Response getInit(

因此它不会天生工作，直到你输入：

@RegisterForReflection
class InitData { ...

但还是。

我觉得我应该是个bug。它的行为方式应该相同。是否原生。

Answer 2

我也认为这是一个错误，但他们在这里解释得更好：https://quarkus.io/guides/writing-native-applications-tips#registering-for-reflection

When building a native executable, GraalVM operates with a closed world 
assumption. It analyzes the call tree and removes all the classes/methods/fields 
that are not used directly.

The elements used via reflection are not part of the call tree so they are dead
code eliminated (if not called directly in other cases). To include these 
elements in your native executable, you need to register them for reflection
explicitly.
