在maven的setting文件中配置了profile:
<profile>  
            <id>dev</id>  
            <properties>  
                <jdbc.driver>net.sourceforge.jtds.jdbc.Driver</jdbc.driver>
<jdbc.url>jdbc:jtds:sqlserver://127.0.0.1:1433;DatabaseName=test</jdbc.url>
<jdbc.username>admin</jdbc.username>
<jdbc.password>admin123</jdbc.password>
            </properties>  
            <activation>  
                <activeByDefault>true</activeByDefault>  
            </activation>  
        </profile>
在pom的build节点下配置resources,用来将setting中的配置内容动态更新到项目中:
<resources>
      <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
        <includes>
          <include>**/*.properties</include>
        </includes>
      </resource>
    </resources>
在mybatis的配置文件中${}使用
发现启动报错:
