<p>前提准备：</p>
<p>　　》IDEA专业版本</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeE5EZzBOVFE1TWkweE1qTTVNVGd6TVRFeUxuQnVadz09" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p> </p>
<h3>1 安装MyBatisCodeHelper-Pro</h3>
<p>　　IDEA提供了插件安装功能，可以根据开发需要安装适合的插件</p>
<p>　　》help -&gt; find action（快捷键：ctrl + shift + A） --&gt;&gt; 搜索 plugins  --&gt;&gt;  选择setting里面的plugins</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeE5URXlNakkyTmkwNU5qUTJNek16T1RNdWNHNW4=" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p>　　》搜索并安装你需要的插件</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeE5UTXhOREl4TWkwek56QTBOVGs0TWpJdWNHNW4=" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p>　　》搜索MyBatisCodeHelper-Pro插件示例（由于我已经安装过了，所以右边是一个uninstall的灰色按钮）</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeE5UUXdOell3TnkweU9EY3hOVGN4TmpZdWNHNW4=" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p>　　》安装完毕后重启IDEA</p>
<p>　　》技巧01：没有激活的MyBatisCodeHelper-Pro插件会在事件log窗口中弹出一个日志，如下所示</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeE5UZ3lPRGMyTlMweE56RTJNRGt4T1RZNExuQnVadz09" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p> </p>
<h3>2 基本使用（未激活时可以使用的功能）</h3>
<h3>　　2.1 mapper接口和mapper文件之间的相互跳转</h3>
<p>　　　　单击左边的图标就可以实现mapper接口和mapper文件之间对应方法的跳转功能</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeU1EQTFNekE0Tnkwek5EWTJNelUyTURrdWNHNW4=" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p>　　　　技巧01：左边的图标是可以进行更改的，setting -&gt; other settings -&gt; MyBatisCodeHelper-Pro -&gt; mapper icon</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeU1ESXpNVEkyTmkweE1qa3pNek01TmpjMExuQnVadz09" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<h3>　　2.2 自动重构</h3>
<p>　　　　修改mapper映射文件中的标签的id属性值后，mapper接口中的对应方法名会自动进行修改，而且反之亦然</p>
<p>　　　　技巧01：将光标放到mapper映射文件中的标签的id属性值上或者mapper接口的方法名上，按 shift + F6 后就可以进行修改啦，修改完成后再按回车按钮进行确认操作</p>
<p>　　　　快捷键：shift + F6</p>
<h3>　　2.3 自动补全功能</h3>
<p>　　　　编辑mapper映射文件中的内容时会自动进行补全操作</p>
<h3>　　2.4 一键删除操作</h3>
<p>　　　　mapper映射文件和mapper接口中有不对应时，mapper映射文件中的内容会变成灰色，mapper接口中的内容会变成红色；此时将光标放到这些区域按 alt + enter 后就可以选择补全对应代码或者进行一键删除操作</p>
<p>　</p>
<h3>3 激活MyBatisCodeHelper-Pro插件</h3>
<h3>　　3.1 进入事件log窗口</h3>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeU1UVXlPVFk1TVMwMk56RTVOelF6TG5CdVp3PT0=" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<h3>　　3.2 获取激活码</h3>
<p>　　　　单击 here 标签就会进入到购买激活码页面</p>
<h3>　　3.3 单击 enter key 标签</h3>
<p>　　　　单击后会弹出一个弹出框，录入二维码即可激活　　</p>
<p>　　　　技巧01：激活后，之前事件log窗口中的 enter key 和 here 标签就会变成灰色的</p>
<p><img src="/default/index/img?u=L2RlZmF1bHQvaW5kZXgvaW1nP3U9YUhSMGNITTZMeTlwYldjeU1ERTRMbU51WW14dlozTXVZMjl0TDJKc2IyY3ZNVEExTnpjMk1pOHlNREU0TVRJdk1UQTFOemMyTWkweU1ERTRNVEl5T0RJeU1qRXpOakF4TlMweE1ESTVOakV4TVRNMUxuQnVadz09" alt="IDEA05 mybatis插件之MyBatisCodeHelper-Pro" title="IDEA05 mybatis插件之MyBatisCodeHelper-Pro"></p>
<p> </p>
<h3>4 MyBatisCodeHelper-Pro高级用法</h3>
<h3>　　4.1 根据java实体类生成基本的CRUD</h3>
<p>　　　　》创建一个实体类</p>
<p>　　　　　　坑01：实体类中的属性不能是pulbic或static修饰，所系下面实体类中的会报一个错，只需要将@Slf4j注解暂时去掉，生成完代码后再加上即可</p>
<p>　　　　　　PS：其实实体类中根本就不需要添加@Slf4j注解，只是三少习惯性的加上了一个而已</p>
