The content of element type "package" must match "(result-types?,interceptors?...

错误：“The content of element type "package" must match "(result-types?,interceptors?,default-interceptor-ref?,default-action-ref?,default-class-ref?,global-results?,global-exception-mappings?,action*)". ”

原因：package里元素必须按照一定的顺序排列：

result-types
interceptors
default-interceptor-ref
default-action-ref
default-class-ref
global-results
global-exception-mappings
action*（所有action放到最后）
