分析了好一大阵后才发现是maven编译时的配置出问题，加上下面这个配置就好了
<build>
...
<resources>
<resource>
<directory>src/main/resources</directory>
<excludes>
<exclude>**/.svn/*</exclude>
</excludes>
</resource>
<resource>
<directory>src/main/java</directory>
<excludes>
<exclude>**/.svn/*</exclude>
</excludes>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
...
</build>
原因在于如果你的资源文件在java包下面，则maven默认打包是不会认为这些资源文件需要打入包内，所以在启动的时候老是会报Invalid bound statement (not found)，而如果资源文件放在resources文件夹下面就不会有问题，这与maven的资源存放机制有关。如果要求maven打包的时候将java包下面的非*.java文件也打入包中，则需要上面这这个配置项。
