ssm 出现 Method threw 'org.apache.ibatis.binding.BindingException' exception.Invalid bound statement (not found)……

运行数据库的增删改查时出现 500状态码 并且提示 Method threw 'org.apache.ibatis.binding.BindingException' exception.Invalid bound statement (not found)，

后来才知道，IDEA的打包时默认不将 xml配置文件打包进去？毕竟在ssm中，SQL语句都是在配置文件中实现的，如果没打包进去怎么运行得起来。

dao层的pom.xml 如下：

注意看66-73行间的代码，加上这部分后每次运行时idea会自动将xml配置文件打包进来

后面的88-108间的代码也可以解决这个问题，不过它每次都要你手动mvn insatll 来打包，当xml有改变时如果不手动打包的话就用不了了。
