Answer 1

确保您的类路径上具有正确的XmlBeans版本（2.x）。

Answer 2

See javadoc :

XmlOptions setSaveAggresiveNamespaces() : Deprecated. replaced by setSaveAggressiveNamespaces() in 2.0 Deprecated. replaced by setSaveAggressiveNamespaces() in 2.0 . You might be using Apache XMLBeans 1.x library. Either use latest release(recommended) or change method call to setSaveAggresiveNamespaces()

Answer 3

Check that your version of xmlbeans is correct. If you are using maven, finds that there is no other unit that contains a different version of xmlbeans. (Use mvn dependency: tree)
