I think the handler example given by @liubao68 cannot meet @liuguangrong 's
needs. Because the transportHandler is the last handler in the source code.
```java
public class ConsumerHandlerManager extends AbstractHandlerManager {
@Override
protected String getName() {
return "Consumer";
}
@Override
protected String getInnerDefaultChainDef() {
return "simpleLB";
}
@Override
protected Handler getLastHandler() {
return TransportClientHandler.INSTANCE;
}
}
```
and in `AbstractHandlerManager.java`
```java
private List<Handler> createHandlerChain(String chainDef) {
List<Class<Handler>> chainClasses = convertToChainClass(chainDef);
List<Handler> handlerList = new ArrayList<>();
for (Class<Handler> cls : chainClasses) {
try {
handlerList.add(cls.newInstance());
} catch (Exception e) {
// 在启动阶段直接抛异常出来
throw new Error(e);
}
}
handlerList.add(getLastHandler());
return handlerList;
}
```
In addition, when the transportHandler calls an exception, it will return
the exception information to the caller. Can the exception information be
handled by the caller? Hope you provide the calling way and error message stack.
