MyBatis-generator常见错误（整合）
错误一：(property*,plugin*,commentGenerator?,(connectionFactory|jdbcConnection)

这个问题我都被折腾了好久。因为我把这段代码的位置，移动了好几个地方，就是差一个地方没有移动到，于是就被折腾了好久。
解决：代码顺序问题！！
以下是正确的 myBatisGeneratorConfig.xml 文件

错误二：Exception getting JDBC Driver: com.mysql.jdbc.Driver
[ERROR] Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate (default-cli) on project ssm01: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.5:generate failed: Exception getting JDBC Driver: com.mysql.jdbc.Driver -> [Help 1]
问题接一连二，用maven mybatis插件，如果不在plugin里面添加依赖包得引用的话，会找不到相关得jar包
解决：在pom.xml中添加依赖
<!-- mybatis-generator -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>${org.mybatis.generator.version}</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
<!--
用maven mybatis插件
如果不在plugin里面添加依赖包得引用的话，会找不到相关得jar包，
在plugin外部得jar包，他不会去找到并执行，
所以要把plugin运行依赖得jar配置都放在里面
