为什么我的分页效果不行啊，也不报错，不分页而且总页数显示也不对
package com.imooc.entity;

/**

*/
private int totalNumber;
/**

*/

/**

*/

}

this.currentPage = 1;
}
// 设置limit的参数
this.dbIndex = (this.currentPage - 1) * this.pageNumber;
this.dbNumber = this.pageNumber;
}

return totalNumber;
}

this.totalNumber = totalNumber;
this.count();
}
