PageHelper pageHelper這個沒有實現Interceptor接口怎么給new Interceptor[]？
新版本中有個PageInterceptor類實現了Interceptor接口，這個時候賦值給new Interceptor[]才可行。
// 設置MyBatis分頁插件
PageInterceptor pageInterceptor = new PageInterceptor();
Properties properties = new Properties();
properties.setProperty("helperDialect", "oracle");
properties.setProperty("offsetAsPageNum", "true");
properties.setProperty("rowBoundsWithCount", "true");
pageInterceptor.setProperties(properties);
bean.setPlugins(new Interceptor[]{pageInterceptor});
