 6     @Bean
 7     public PaginationInterceptor paginationInterceptor() {
 8         PaginationInterceptor paginationInterceptor = new PaginationInterceptor();

10         // paginationInterceptor.setOverflow(false);
11         // 设置最大单页限制数量，默认 500 条，-1 不受限制
12         // paginationInterceptor.setLimit(500);
13         // 开启 count 的 join 优化,只针对部分 left join
14         paginationInterceptor.setCountSqlParser(new JsqlParserCountOptimize(true));
15         return paginationInterceptor;
16     }
