请问，该怎么解决，谢谢

Answer 1

有可能是jar包冲突,有时即使你的代码都没问题,还是报错的话,你就该找找jar问题了

Answer 2

这个问题可能是你的配置文件没有写全，或者类没有对应上，也可能是没有set get方法 原因很多。

Answer 3

这样吧，你打开你导入的jar包，按照你写的路径（applicationContext.xml文件中）去找
TransactionManager类，如果连包都找不到，那你就得导包啦！

Answer 4

看这行
nested exception is java.lang.NoClassDefFoundError: javax/transaction/TransactionManager
找不到这个类 事务管理的包没引进去把
