问题描述
我遵循了Jersey 2.0文档( https://jersey.java.net/documentation/latest/user-guide.html#json.moxy )，修改后的pom.xml，包括jersey-media-moxy构件，已编译并安装.对于Produce和Consume案例，我都可以获得从POJO到JSON的基本映射工作.
I followed the Jersey 2.0 document (https://jersey.java.net/documentation/latest/user-guide.html#json.moxy), modified pom.xml, included jersey-media-moxy artifact, compiled and installed. I could get basic POJO to JSON mapping work for both Produces and Consumes cases.
但是，当我尝试使用一些具有复杂数据类型的POJO作为资源返回类型时，出现了很多Status 500 Internal Server Error，但没有任何服务器日志.这很烦人.有人知道这是一个错误还是我错过了配置中的某些内容?
However, when I tried with some POJO with complex data type as resource return type, I got a lot Status 500 Internal Server Error but without any server log. It is very annoying. Does anybody know if it is a bug or I missed something in configuration?
顺便说一句，为了对POJO对象使用Moxy映射，POJO需要有一个空的参数构造函数.还有其他要求吗?
By the way, in order to use Moxy mapping for a POJO object, the POJO needs to have a empty parameter constructor. Are there any other requirements?
推荐答案
我遇到了同样的问题，并发现了这篇文章:
I had the same problem and found this post:
作者实现了ApplicationEventListener来记录Moxy抛出的异常.这是我的实现(需要在您的应用程序中注册):
The author implemented ApplicationEventListener to log the exceptions thrown by Moxy. This is my implementation (needs to be registered in your application):
public class ExceptionListener implements ApplicationEventListener {
@Override
public void onEvent(ApplicationEvent event) {
}
@Override
public RequestEventListener onRequest(RequestEvent requestEvent) {
return new ExceptionRequestEventListener();
}
public static class ExceptionRequestEventListener implements RequestEventListener{
private final Logger logger;
public ExceptionRequestEventListener(){
logger = Logger.getLogger(getClass());
}
@Override
public void onEvent(RequestEvent event) {
switch (event.getType()){
case ON_EXCEPTION:
Throwable t = event.getException();
logger.error("Found exception for requestType: "+event.getType(), t);
}
}
}
}
这篇关于泽西岛2.0和Moxy内部服务器错误，但没有服务器日志的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
