關於mybatis生成外掛Generator配置檔案中自定義註釋

1.編寫一個實現org.mybatis.generator.api.CommentGenerator介面的類。這個類有預設的實現，不會寫可以參考預設實現

org.mybatis.generator.internal.DefaultCommentGenerator

2.在maven外掛中新增依賴

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.3</version>
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.37</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.5</version>
        </dependency>
        <dependency>
            <groupId>com.demo.aaa</groupId>
            <artifactId>bbb</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
</plugin>

如上將驅動也新增到以來中，就可以不用在配置檔案中增加classPathEntry元素。
bbb是專案本身，需要先在本地安裝方可引用。


如上配置完成後在外掛的配置檔案中

<commentGenerator type="com.zhaolu.tian.MyComment">
    <property name="suppressAllComments" value="true"/>
    <property name="suppressDate" value="true"/>
</commentGenerator>

如此指定實現類即可。

最後提醒一下：有個坑，mysql的java驅動對於generator外掛高版本的不適用，還是用低版本的吧。5.1.37就挺好的不是嘛

最後貼一個完整的配置，好以後拿來就用。
