• mapper.xml文件内容

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC

• 这时，项目部署的话会抛出IOException
  

• 那么问题就来了，明明配置好了啊（不要问我明明是谁，我哪知道）

打开target文件夹，展开dao？？？

映射文件呢，让我吃了。。。。

这是因为maven在build项目时只会将src/main/java/下的*.java文件编译到class文件夹下，而xml文件没有被build到class文件夹下，所以会抛出IOException

• 怎么解决呢？？这个时候只需在pom文件中加入如下代码

<build>
    <finalName>springmvc</finalName>

    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.xml</include>
        </includes>
        <filtering>true</filtering>
      </resource>
    </resources>

  </build>

主要是<resources>节点的配置，配置完之后就可以正常部署了
不足之处请大家指出，谢谢！！
