mybatis--maven默認不會將java下xml文件打包至classpath導致的問題

分析了好一大陣后才發現是maven編譯時的配置出問題,加上下面這個配置就好了
<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>
原因在於如果你的資源文件在java包下面,則maven默認打包是不會認為這些資源文件需要打入包內,所以在啟動的時候老是會報Invalid bound statement (not found),而如果資源文件放在resources文件夾下面就不會有問題,這與maven的資源存放機制有關。如果要求maven打包的時候將java包下面的非*.java文件也打入包中,則需要上面這這個配置項。
