我在
eclipse中开发了一个
Spring JPA项目,可以访问存储在MysqL服务器中的数据.现在我需要在Spring @ MVC项目中导入这个项目.所以
>我在JPA项目的构建路径中配置导出maven依赖关系
>我将项目添加到tomcat的bootstrap类路径中,
>我将JPA / Spring项目添加到我的Spring @MVC项目的类路径中
>我还将jpa应用程序上下文添加到MVC项目的根上下文中.
当我尝试在tomcat服务器上运行应用程序,我收到一个错误.似乎我的spring-beans库缺少,但你可以看到在pom配置我导入它.这是错误日志：

解决方法
在我的情况下,冲突是由春天的安全造成的,而安全性仍然在使用旧版本.
我把一些不包括在它上面,现在没关系.
将这些东西放在依赖管理中也可能是一件好事,所以你不必在每个模块中重复.

没有排除我有与本线程开头所述相同的错误.
我在春季使用的版本是：
<properties>
<spring.framework.version>3.1.1.RELEASE</spring.framework.version>
<spring.security.framework.version>3.1.0.RELEASE</spring.security.framework.version>
</properties>
