MybatisPlus的分页插件会自动优化LeftJoin语句

paginationInnerInterceptor.setOptimizeJoin(false);

 @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        PaginationInnerInterceptor paginationInnerInterceptor = new PaginationInnerInterceptor(DbType.getDbType(dbType));
        // 关闭生成 countSql 优化掉 join
        paginationInnerInterceptor.setOptimizeJoin(false);
        interceptor.addInnerInterceptor(paginationInnerInterceptor);
        interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
        return interceptor;
    }
