1、@Intercepts({@Signature(type =StatementHandler.class, method = "prepare", args ={Connection.class, Integer.class})})

2、

类型 MetaObject 中的方法 forObject（Object, ObjectFactory, ObjectWrapperFactory, ReflectorFactory）对于参数（StatementHandler, ObjectFactory, ObjectWrapperFactory）不适用

解决办法：

MetaObject metaObject = MetaObject.forObject(statementHandler, SystemMetaObject.DEFAULT_OBJECT_FACTORY, SystemMetaObject.DEFAULT_OBJECT_WRAPPER_FACTORY, new DefaultReflectorFactory());

使用默认的ReflectorFactory接口的实现类
