Answer 3

我是用eclipse导出的，export->runnable->package required
你是这种么

Answer 4

嗯。我照着你说的样子做了测试。确实，存在你说的问题。具体问题我还没有找到。
不过，正如你说的：在eclipse中运行是正常的，eclipse导出之后就有问题了。应该是在eclipse运行时存在某个“eclipse的环境因素”，程序可以正常运行。经过eclipse导出之后，这个“环境因素”丢失了，就无法运行了。或者是eclipse的导出存在问题，也会导致这样的问题。
我也没有找到问题。如果你很着急的话，还是用spring的xml里面进行bean的配置吧，不采用“注释”的方式。
如果你的问题解决了，请在这里跟帖。我也很想知道为什么。谢谢！
