## 插件
mybatis允许通过interceptor对mapped statement的执行进行拦截，mybatis支持拦截如下调用：
- Executor(update, query, flushStatements, commit, rollback, getTransaction, close, isClosed)
- ParameterHandler (getParameterObject, setParameters)
- ResultSetHandler (handleResultSets, handleOutputParameters)
- StatementHandler (prepare, parameterize, batch, update, query)
