Idea中这么配置就可以了。

重点注意以下几点

如果不再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

另外generatorConfig.xml里面得targetProject，可以写成src/main/java，也就是Maven管理得编译代码路径，我之前用generator插件右键生成可以写项目名，但是在这里就不好用了。

generatorConfig.xml如果不写路径的话，默认是读取src/main/resource下面得

关于M2E 的Eclipse插件，目前还不支持execution

报如下错误

Plugin execution not covered by lifecycle configuration

官方文档给出的如下
https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html
修改一下写成如下：

<build>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>

</execution>
</executions>
<configuration>

<overwrite>true</overwrite>

这样就不会报错了。
再贴上配置文件：<?xml version="1.0" encoding="UTF-8"?>

<!-- 列出要生成代码的所有表，这里配置的是不生成Example文件 -->
<table tableName="xxx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="xx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

</context>
</generatorConfiguration> 差点忘记了，还需要一个db.properties文件，这个应该很常见了
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xxx?characterEncoding=utf-8
jdbc.username=root
jdbc.password=

好了，这样就可以了，Maven Run一下就行了
