IllegalArgumentException: Could not resolve resource location pattern [classpath .xml]: class path resource cannot be resolved to URL because it does not exist

查看编译后的classes文件后，没有mapper.xml文件，所以SQLsessionfactory不能读取成功。

在Maven中加入如下的resources配置：

<dependencies>
//相关的依赖包
</dependencies>
.....
<resources>
      <resource>
        <directory>src/main/resources</directory>
        <includes>
          <include>**/*.properties</include>
          <include>**/*.xml</include>
          <include>**/*.tld</include>
        </includes>
        <filtering>false</filtering>
      </resource>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.properties</include>
          <include>**/*.xml</include>
          <include>**/*.tld</include>
        </includes>
        <filtering>false</filtering>
      </resource>
</resources>
