1、首先在pom.xml中添加如何配置

<build>

       <resources>
           <resource>
               <directory>src/main/resources</directory>
               <includes>
                   <include>**/*</include>
               </includes>
           </resource>
           
           <resource>
               <directory>src/main/resources</directory>
               <includes>
                   <include>jdbc.properties</include>
               </includes>
               <filtering>true</filtering>
           </resource>
       </resources>
   </build>

<profiles>
       <profile>
           <id>test</id>
           <activation>
               <activeByDefault>false</activeByDefault>
           </activation>
           <properties>
               <jdbc.driver>test.dirver</jdbc.driver>
               <jdbc.url>test.url</jdbc.url>
               <jdbc.username>test.username</jdbc.username>
               <jdbc.password>test.password</jdbc.password>
           </properties>
       </profile>
       <profile>
           <id>dev</id>
           <activation>
               <activeByDefault>false</activeByDefault>
           </activation>
           <properties>
               <jdbc.driver>dev.dirver</jdbc.driver>
               <jdbc.url>dev.url</jdbc.url>
               <jdbc.username>dev.username</jdbc.username>
               <jdbc.password>dev.password</jdbc.password>
           </properties>
       </profile>
       <profile>
           <id>product</id>
           <activation>
               <activeByDefault>true</activeByDefault>
           </activation>
           <properties>
               <jdbc.driver>product.dirver</jdbc.driver>
               <jdbc.url>product.url</jdbc.url>
               <jdbc.username>product.username</jdbc.username>
               <jdbc.password>product.password</jdbc.password>
           </properties>
       </profile>
   </profiles>

2、修改配置文件

jdbc.driver = ${jdbc.driver}
jdbc.url = ${jdbc.url}
jdbc.username = ${jdbc.username}
jdbc.password = ${jdbc.password}

说明：配置文件中${key} key即对应pom.xml中的jdbc.driver,jdbc.url,jdbc.username,jdbc.password四个选项。
