title="Mybatis 插件介绍"></a>Mybatis 插件介绍</h2><p>Mybatis 借助于四大核心对象（Executor、StatementHandler、ParameterHandler、ResultSetHandler）对持久层的进行操作。支持用插件对四大核心对象进行拦截，增强核心对象的功能。<br>增强功能本质上是借助于底层的动态代理实现的，所以 MyBatis 中的四大对象都是代理对象。<br><img src="https://img-blog.csdnimg.cn/7030a1d9bbd44b708a3797128d232b8c.png"><br>MyBatis 所允许拦截的方法如下:</p>
<ul>
<li>执行器 Executor（update、query、commit、rollback等方法）</li>
<li>SQL语法构建器 StatementHandler（prepare、parameterize、batch、updates query 等方法）</li>
<li>参数处理器 ParameterHandler（getParameterObject、setParameters方法）</li>
<li>结果集处理器 ResultSetHandler（handleResultSets、handleOutputParameters等方法）</li>
</ul>

<ol>
<li>每个创建出来的对象不是直接返回的，而是通过 interceptorChain.pluginAll(parameterHandler) 方法的代理对象。</li>
<li>pluginAll 会调用所有的 Interceptor 的 plugin 方法，返回被重重代理后的对象。<br><img src="https://img-blog.csdnimg.cn/da2d48a62132481e898ecb5074296602.png"><br>四大组件都会调用 interceptorChain.pluginAll 生成代理对象<br><img src="https://img-blog.csdnimg.cn/6883a10b67784fa5a4c2d5648f670e77.png"></li>
