Failed to introspect Class [com.mchange.v2.c3p0.ComboPooledDataSource] from ClassLoader [ParallelWeb
主要问题：Caused by: java.lang.IllegalStateException: Failed to introspect Class [com.mchange.v2.c3p0.ComboPooledDataSource] from ClassLoader [ParallelWebappClassLoader
这个错误真的是令人很崩溃，看错误信息一直以为是Spring配置文件中在配置时出现的错误，找了半个多小时查看哪里有错误，不停地修改运行就是找不到，于是决定去看看是否少了什么jar包，发现配置数据源时用的mchange-commons-java-0.2.19.jar没有添加进来，抱着试试看的心理，添加好jar后，点击运行，结果：运行成功
那个jar包可以去maven仓库下载：mchange-commons-java-*.jar
mchange-commons-java-*.jar
mchange-commons-java-0.2.3.4是什么包？
这是c3p0数据库连接池的辅助包，如果没有这个包系统启动时会报classnotfoundexception，这是更新c3p0-0.9.2版本后分离出来的包，0.9.1的时候还是只是一个包。具体的可以参考这篇博客“http://…”
