由于安装了 JDK1.8 的版本,最近在进行整合 Struts2+Spring+Hibernate 框架的时候,不小心导入了之前下载的 Spring 3.2.0 版本的 jar 包。
结果在运行测试用例的时候,总是显示红条,报出 java.lang.IllegalStateException: Failed to load ApplicationContext 的错误。
异常描述:

经查明问题的原因是:安装的 JDK 版本和 Myeclipse 项目 lib 中导入的 Spring 的 jar 包版本存在不兼容的情况。
解决办法:
一:把 JDK 版本换成1.7 or 1.7以下
二:使用 Spring 4.0 RELEASE 及以上版本
关于 JDK 各个版本的下载:

关于 Spring 各个版本 jar 包的下载:
可以点击链接:http://repo.spring.io
鼠标点击左侧导航栏 –> 符号展开菜单选择 Artifacts 选项 –> 选择子菜单下的 libs-release-local 选项 –> 依次进入其子目录 org/springframework/spring 就可以看到 spring 各版本信息了 –> 选择需要的 spring 版本 ( 例如 4.3.8.RELEASE ,点击打开选择 spring-framework-4.3.8.RELEASE-dist.zip ),下载解压即可获得 jar 包、api 等文件。
