soap webservices - 返回错误消息？

Question

I have a little soap webservice. And I wonder how I can response with errors.

Eg:

public int createUser(String username) {
   //create...
   return id;
}

Now, if the user could not be created, how do I make a proper response? Do I have to throw a custom exception? Which is the right way?

Answer 1

这里正确的方法是将异常转换为SOAP Fault 。

Answer 2

My experience with this is that we created a common class that gets returned along with the data class. So for example, the soap response comes back with a CommonOut object and a ResultData object. The CommonOut class contains fields that are populated with data whether the request is good or bad such as Status, Records Returned, and Message.

An interceptor is used to catch all exceptions in the container and wrap them in our custom format and returned to the user. That way you can catch the real exception messages and wrap them in your own format.

The danger of returning the real error messages to the caller is that it could expose details about your system potentially unless you catch exceptions and override the values that get returned.

This is similar to the SOAP fault mentioned above, but gives you more ability to customize your output format.

Answer 3

我在我的SOAP服务器中执行此操作 - 但是不要试图构建自己的Soap错误 - 只是抛出一个运行时异常并且应该转换为soap错误。
