解决导入 Eclipse Maven 工程后无法读取 .xml 文件的问题
IDEA 与 Eclipse 配置文件目录的方式不同，可以将文件夹标记为 Sources、Resources 和 tests 等，而 src/main/java 默认被标记为 Sources，src/main/resources 才默认被标记为 Resources，编译时自动复制。
这样放在 src/main/java 目录下的文件与子文件夹均为 Sources，只将编译生成的 .class 文件复制到编译目录，在 Eclipse Maven 工程里放在 src/main/java 文件夹里的 xml、props 和 properties 文件就不会被拷贝到编译文件夹，导致执行时找不到这些文件，报类似下面这样的错误：
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring-demo.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring-demo.xml] cannot be opened because it does not exist

解决方案：
可以通过在 pom.xml 文件里添加 resources 配置来指定将哪些文件作为 resources 包含：
<build>
<resources>
<resource>
<directory>${basedir}/src/main/java</directory>
<includes>
<include>**/*.props</include>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
</build>
如何导出 jar 包
File -> Project Structure -> Artifacts -> Click green plus sign -> Jav -> From modules with dependencies
Build -> Build Artifacts
