[英]What kind of exception to manually throw from an Axis web service?
I have some webservices that are developed on axis 1.1, and I need to make a few changes. 我有一些在1.1轴上开发的web服务,我需要进行一些更改。 During this I am fixing up the exception handling code, but I don't know what kind of exception I should throw when there is an error. 在此期间,我正在修复异常处理代码,但我不知道在出现错误时应该抛出什么样的异常。
I only need to send the message to the client, I don't need to worry about stack traces and custom information in the exceptions. 我只需要将消息发送给客户端,我不需要担心异常中的堆栈跟踪和自定义信息。 I don't want to deal with extending soapfaults, or providing reasons for the failures, and all that jazz. 我不想处理扩展的soapfaults,或提供失败原因,以及所有爵士乐。
@WebMethod
public string[] myMethod() throws ..?.. {
throw new AxisFault(); // not recommended
throw new SOAPFaultException(); // seems overly general
throw new Exception(); // what we have now
}
Is there any right way to do this, or is throw new Exception
the right way to go about it? 有没有正确的方法来做到这一点,或者throw new Exception
是正确的方法呢?
You may create a custom exception (say FooException
) extending Exception
annotated with JAX-WS @WebFault
. 您可以创建一个自定义异常(比如FooException
),扩展使用JAX-WS @WebFault
注释的Exception
。
@WebFault(faultBean = "org.foo.bar.FooFault")
public class FooException extends Exception {
private FooFault fooFault;
public FooException() {
super();
}
public FooException(String message, FooFault fooFault, Throwable cause) {
super(message, cause);
this.fooFault = fooFault;
}
public FooException(String message, FooFault fooFault) {
super(message);
this.fooFault = fooFault;
}
public FooFault getFaultInfo() {
return fooFault;
}
}
// this is org.foo.bar.FooFault
public class FooFault {
// POJO
}
And then you declare that your web method throws that exception. 然后你声明你的web方法抛出了那个异常。
@WebMethod
public string[] myMethod() throws FooException {
// do some stuff
throw new FooException();
// or with a cause
try {
// something dangerous
} catch (Exception e) {
throw new FooException("Shit happens", new FooFault(), e);
}
// or like this
throw new FooException("Foo", new FooFault());
}
JAX-WS should do the rest. JAX-WS应该完成其余的工作。
