首先，來看下MAVENx專案標準的目錄結構：

一般情況下，我們用到的資原始檔（各種xml，properites，xsd檔案等）都放在src/main/resources下面，利用maven打包時，maven能把這些資原始檔打包到相應的jar或者war裡。

有時候，比如mybatis的mapper.xml檔案，我們習慣把它和Mapper.java放一起，都在src/main/java下面，這樣利用maven打包時，就需要修改pom.xml檔案，來把mapper.xml檔案一起打包進jar或者war裡了，否則，這些檔案不會被打包的。（maven認為src/main/java只是java的原始碼路徑）。網路上有很多方法，我大概試了下，幾種方法都可以，可以任選一種即可。

方法1，其中**/*這樣的寫法，是為了保證各級子目錄下的資原始檔被打包。

1. <build>  
2.     <finalName>test</finalName>  
3.     <!--  
4.     這樣也可以把所有的xml檔案，打包到相應位置。  
5.     <resources>  
6.         <resource>  
7.             <directory>src/main/resources</directory>  
8.             <includes>
     
9.                 <include>**/*.properties</include>  
10.                 <include>**/*.xml</include>  
11.                 <include>**/*.tld</include>  
12.             </includes>  
13.             <filtering>false</filtering>  
14.         </resource>  
15.         <
    resource>  
16.             <directory>src/main/java</directory>  
17.             <includes>  
18.                 <include>**/*.properties</include>  
19.                 <include>**/*.xml</include>  
20.                 <include>**/*.tld</include>  
21.             </includes>  
22.             <filtering>false</filtering>  
23.         </resource>  
24.     </resources>  
25. </build>  

方法2，利用build-helper-maven-plugin外掛

1. <build>  
2.     ...  
3.     </plugins>  
4.         ...  
5.         <!--  
6.         此plugin可以用  
7.         利用此plugin，把原始碼中的xml檔案，  
8.         打包到相應位置，這裡主要是為了打包Mybatis的mapper.xml檔案   
9.         -->  
10.         <plugin>  
11.             <groupId>org.codehaus.mojo</groupId>  
12.             <artifactId>build-helper-maven-plugin</artifactId>  
13.             <version>1.8</version>  
14.             <executions>

25.                                 <includes>  
26.                                     <include>**/*.xml</include>  
27.                                 </includes>  
28.                             </resource>

33.         </plugin>     
34.         ...  
35.     </plugins>       
36.     ...  
37. </build>  

方法3，利用maven-resources-plugin外掛

1. <build>  
2.     ...  
3.     </plugins>  
4.         ...  
5.         <!--  
6.         此plugin可以用
