java.lang.NoSuchMethodError: antlr.collections.AST.g（truts2与hibernate jar包(antlr-2.7.2.jar)冲突）

报错代码如下:

原因：Struts自带的antlr-2.7.2.jar,比Hibernate4.1.4自带的antlr-2.7.7.jar的版本要低，故要删除前一个低版本的，struts1.3 和2.1都带有antlr-2.7.2.jar

解决方案：不加载struts自带的antlr-2.7.2.jar。

步骤：选择项目点击右键——>“Build Path“——>“Configure Build Path”——>选中"Struts2.1 Librarys”——>点击右边的“Edit”——>展开"Core"——>取消勾选”antlr-2.7.2.jar"。OK！

如图：
