maven踩过的坑

maven配置

1. maven默认配置
   解决每次打开idea的spring项目都需要重新配置maven，选择file/other settings/preference for new projects
   
   然后配置maven即可
   
2. maven已经有了依赖，却显示找不到
   
   解决方法：配置runner
   
3. maven默认只会将resources下的资源文件进行打包，如果在java文件下有配置文件，则需要在maven的里添加

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.yml</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.yml</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
