我读了很多关于如何在payara 5上替换jackson for moxy但是从来没有找到一个好的解决方案,所以我创建了一个小项目并希望有人可以帮助我.
的pom.xml

App.java
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import org.glassfish.jersey.jackson.JacksonFeature;
@ApplicationPath("/api")
public class App extends Application {
@Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new java.util.HashSet<>();
resources.add(JacksonFeature.class);
resources.add(SimpleService.class);
return resources;
}
}
SimpleService.java
@Path("sample")
public class SimpleService {
@Path("greet2")
@GET
@Produces(MediaType.APPLICATION_JSON)
public PojoEntity doGreet2() {
PojoEntity pojoEntity = new PojoEntity();
pojoEntity.setTeste1("TesteValue1");
pojoEntity.setTeste2("TesteValue2");
return pojoEntity;
}
}
PojoEntity.java
public class PojoEntity {
private String teste1;
@JsonProperty("differentName")
private String teste2;
//getters and setters
}
将此微应用程序部署到payara 5并请求端点http://localhost:8080/micro-sample/api/sample/greet2后,结果是(如预期的那样):
{"teste1":"TesteValue1","differentName":"TesteValue2"}
Payara使用的是Jackson而不是moxy. :)太棒了!
==============================================
我的问题是当我使用microprofile到达我自己的端点时:
SimpleServiceMicroprofileApi.java
import javax.enterprise.context.Dependent;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;
@Dependent
@RegisterRestClient
@Produces(MediaType.APPLICATION_JSON)
public interface SimpleServiceMicroprofileApi {
@Path("api/sample/greet2")
@GET
@Produces(MediaType.APPLICATION_JSON)
public PojoEntity recallGreet2();
}
MicroService.java
package fish.payara.micro.sample;
import java.net.MalformedURLException;
import java.net.URL;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.eclipse.microprofile.rest.client.RestClientBuilder;
@Path("micro")
public class MicroService {
@Path("recallGreet2")
@GET
@Produces(MediaType.APPLICATION_JSON)
public PojoEntity recallGreet2() throws MalformedURLException {
PojoEntity pojoEntity = new PojoEntity();
pojoEntity.setTeste1("LOL");
pojoEntity.setTeste2("LOL2");
URL apiUrl = new URL("http://localhost:8080/micro-sample");
SimpleServiceMicroprofileApi playlistSvc = RestClientBuilder.newBuilder().baseUrl(apiUrl)
.build(SimpleServiceMicroprofileApi.class);
return playlistSvc.recallGreet2();
}
}
并在getClasses方法的App.java上添加以下行:
resources.add(MicroService.class);
通过此修改重新部署后,我们可以访问http://localhost:8080/micro-sample/api/micro/recallGreet2,结果是:
{"teste1":"LOL","differentName":null}
显然,microprofile一直使用moxy并忽略PojoEntity属性“differentName”.
在这个例子中,有人知道如何完全取代moxy for jackson吗?
该项目于here开始提供,可以测试这种情况. 🙂
Payara版本:5.183
提前致谢.
最佳答案 您只需要在SimpleServiceMicroprofileApi上注册JacksonFeature:
@RegisterProvider(JacksonFeature.class)
这应该使它工作;)
