你贴下配置文件呗

我按自己理解说一下(不确定一定正确，你可以试一下)： web-inf 目录应该不属于classpath，所以你把applicationContext.xml等文件放到web-inf时spring其实并没有加载这个文件，你试着把applicationContext.xml等文件放到src目录下试一下 【 在 TRone 的大作中提到: 】 : 架个环境都已经好久了...但是在连数据库这里就卡住了... : spring的配置文件也加载了，没有报错。 : mybatis的配置文件在spring的配置文件中定义了，检查了好多次的配置文件都没有问题啊... : ...................
