## 简介 ##

**说明**

本文介绍maven如何将公共项目的resources下边的资源给包含到当前项目。

本文方法不仅可以用来指定公共的配置文件，也可以指定Mybatis的xml的位置等。

maven支持用\*进行匹配：

*  \*\*：多级路径
 *  \*：所有文件
 *  \*.yml：所有以.yml结尾的文件

**问题的引出**

在Java后端开发中，像数据库配置、Redis配置等一般都是整个项目公用的，这些应该放到公共项目中去配置，然后各个应用项目将这个公共项目的配置给包含进来。

**需求描述**

有个公共项目（common），resources目录下存放数据库的配置，业务项目（account）引用公共项目的配置。

common的结构

## 方案1：配置build =>resources ##

account项目的pom.xml添加如下配置

<build>
    	<resources>
    		<resource>
    			<directory>src/main/resources</directory>
    			<includes>
    				<include>**/*</include>
    			</includes>
    			<filtering>false</filtering>
    		</resource>
    		<resource>
    			<directory>../common/src/main/resources</directory>
    			<includes>
    				<include>**/*</include>
    			</includes>
    			<filtering>false</filtering>
    		</resource>
    	</resources>
    </build>

## 方案3：maven-resources-plugin ##

account项目的pom.xml添加如下配置：

<build>  
          
        </plugins>  
            <plugin>  
                <artifactId>maven-resources-plugin</artifactId>  
                <version>2.5</version>  
                <executions>  
                    <execution>  
                        <id>add-resources</id>  
                        <phase>process-sources</phase>  
                        <goals>  
                            <goal>copy-resources</goal>  
                        </goals>  
                        <configuration>  
                            <outputDirectory>${basedir}/target/classes</outputDirectory>  
                            <resources>  
                                <resource>  
                                    <directory>${basedir}/../common/src/main/resouces</directory>  
                                    <includes>  
                                        <include>**/*</include>  
                                    </includes>  
                                </resource>
    							<resource>  
                                    <directory>${basedir}/src/main/resouces</directory>  
                                    <includes>  
                                        <include>**/*</include>  
                                    </includes>  
                                </resource>
                            </resources>  
                        </configuration>  
                    </execution>  
                </executions>  
            </plugin>     
        </plugins>       
    </build>

## 方案3：**build-helper-maven-plugin** ##

account项目的pom.xml添加如下配置：

<build>  
          
        </plugins>   
            <plugin>  
                <groupId>org.codehaus.mojo</groupId>

                    <execution>  
                        <id>add-resources</id>  
                        <phase>generate-resources</phase>  
                        <goals>  
                            <goal>add-resource</goal>  
                        </goals>  
                        <configuration>  
                            <resources>  
                                <resource>  
                                    <directory>../common/src/main/reources</directory>  
                                    <includes>  
                                        <include>**/*</include>  
                                    </includes>
                                </resource>
    							<resource>  
                                    <directory>src/main/resources</directory>  
                                    <includes>  
                                        <include>**/*</include>  
                                    </includes>
                                </resource>  
                            </resources>  
                        </configuration>  
                    </execution>  
                </executions>  
            </plugin>
