This error usually shows up when incomptiable versions of jars are used, for example spring-asmand spring-core. Have a look at forum.springsource.org/showthread.php?133341
当使用不可兼容版本的 jars 时，通常会出现此错误，例如spring-asm和spring-core。看看forum.springsource.org/showthread.php?133341

In spring version > 3.2.0, you no longer need to explicitly include spring-asmsince it has already been included in spring-core.
在 spring 版本 > 3.2.0 中，您不再需要显式包含，spring-asm因为它已经包含在spring-core.
Remove spring-asmfrom your build definition and ensure that spring-coreis there.
spring-asm从您的构建定义中删除并确保它spring-core在那里。

Update for those moving to versions above 3.1.x ... as made clear by this answer herethere is no longer a separate spring-asm, so it would be better to exclude spring-asmaltogether, once you're at Spring version 3.2.x
更新那些迁移到 3.1.x 以上版本的人......正如这里的答案所表明的那样，不再有单独的spring-asm，所以最好spring-asm完全排除，一旦你在 Spring 版本 3.2.x
