您可以创建一个自定义异常(例如FooException
)扩展Exception
用 JAX-WS 注释@WebFault
。
@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
}
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 应该做剩下的事情。
