Java 连接池和数据库创建上的Hibernate和Spring集成错误

我正在尝试制作一个集成Spring和Hibernate的web应用程序。我得到的不是一个例外，但我的日志继续生成消息，在我看来，这些消息强调了db generation\connection中的一个问题。我声明了一个可以由hsql swing管理器访问的hsql数据库，但db文件在文件资源管理器中不可见。我得到的不是test.db，而是以下文件：

• testdb.lck
• testdb.log
• testdb.properties
• testdb.script

日志警告是以下消息；在谷歌上搜索似乎不是问题，但消息每秒都会生成，似乎关闭了所有连接池并创建了新的IStance：

很抱歉代码的格式设置，但它似乎不太喜欢xml，希望有人能编辑我的消息。

你真的看过你的日志了吗？它没有生成错误，只是生成了一条调试消息。好的，这不是错误，但该消息会稍微提醒我一点。并且数据库文件没有生成。对于初学者，停止加载应用程序两次。。。通过

DispatcherServlet

和

ContextLoaderListener

加载相同的配置，可以有效地加载整个应用程序两次。Next

testdb

和

test.db

既不是打字错误，也不是指向错误的文件。如果我删除web.xml中的

ContextLoaderListener

声明，应用程序将启动，但hibernate甚至不尝试创建db，spring也不会实例化bean。顺便说一下，数据库名称错误只是一个输入错误，我使用的每个名称都会导致生成我之前说过的文件，但是数据库文件没有生成。很明显，因为现在只加载mvc的东西。您应该从

ContextLoaderListener

加载的文件中删除

WEB-INF/spring mvc servlet.xm

。
