警告: A C3P0Registry mbean is already registered. This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources.

参数不合法啊，代码贴出来看看

你这是怎么回事，是不是使用了多个c3p0..
[解决办法]
参数类型不匹配
Object value=rs.getObject(name);
Field f=bean.getClass().getDeclaredField(name);
f.setAccessible(true);
f.set(bean, value);
value的类型，与bean中的属性类型不匹配
