使用mybatis-generator自动生成mapper、dao等文件时，报错如下：
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:generate (default-cli) on project ssm: <properties> resource does not exist
错误原因是maven无法找到对应<properties> resource文件.
解决方法如下：
1.检查properties文件,每一行的行首和行末，是否有多余的空格，将其删掉;
2.在maven的pom.xml文件中，加入如下的<resource>配置：
<dependencies> <!--相关的依赖文件--> </dependencies> <bulid> <plugins> <!--相关的插件--> </plugins> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> </includes> </resource> </resources> </build>
