使用p6spy打印hibernate或者PreparedStatement的带参数值的sql语句

不管在何种环境下用过hibernate的人都知道，哪怕用了show_sql打印出来的sql也是由占位符号的，占位符号的参数值是没有显示出来的，这个开发调试过程中很不方便。同样就算是原生的PreparedStatement同样如此，那有没有办法可以做到打印出来完整的带参数值的sql呢？答案是有的，利用p6spy，下载地址是：sourceforge.net/projects/p6spy/，需要翻墙才可以打开，下载后解压，看到一个p6spy.jar和一个spy.properties，分别吧jar加入classpath中，spy.properties放入到你的src目录下即可，修改properties中的数据源，比如我的是mysql，我修改成如下：

然后把真正用到数据源的地方修改成：com.p6spy.engine.spy.P6SpyDriver即可。

 

我是用的spring3来做的，所以只需要修改上面几个地方即可，别的无需在做修改，就可以使用了。。
