spring：为什么我得到ClassNotFoundException:org.springframework.expression.ExpressionParser？

类org.springframework.expression.ExpressionParser位于包含的spring表达式中，如下所示。 那么，为什么在初始化spring上下文时会出现这样的错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/expression/ExpressionParser
at org.springframework.context.support.AbstractApplicationContext.prepareBeanFactory(AbstractApplicationContext.java:556)

Caused by: java.lang.ClassNotFoundException: org.springframework.expression.ExpressionParser

线程“main”java.lang.NoClassDefFoundError中的异常：org/springframework/expression/ExpressionParser 位于org.springframework.context.support.AbstractApplicationContext.prepareBeanFactory（AbstractApplicationContext.java:556） 位于org.springframework.context.support.AbstractApplicationContext.refresh（AbstractApplicationContext.java:457） 位于org.springframework.context.support.ClassPathXmlApplicationContext。（ClassPathXmlApplicationContext.java:139） 位于org.springframework.context.support.ClassPathXmlApplicationContext。（ClassPathXmlApplicationContext.java:83） 位于com.cgi.tapestry.dbtest.JdbcTest.main（JdbcTest.java:22） 原因：java.lang.ClassNotFoundException:org.springframework.expression.ExpressionParser My pom.xml：

我想我的maven回购协议不知怎么搞砸了。 我注意到我在org下有两个“springlike”目录：

springframework
springexpression

我消灭了他们，解决了问题。此外，只有springframework重新生成
