一：問題提出：
使用SSM框架做一個權限後臺管理項目時，利用PageHelper插件進行分頁查詢時，突然出現以下異常：
HTTP Status 500 – Internal Server Error

第一次使用Oracle數據庫進行項目的開發，檢查寫的OrdersDao和OrdersServiceImpl都沒有語法錯誤，在OrdersServiceImpl裏去掉分頁查詢語句可以完美運行：
package com.xy.service.impl;
import com.github.pagehelper.PageHelper;
import com.xy.dao.OrdersDao;
import com.xy.domain.Orders;
import com.xy.service.OrdersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
@Transactional
public class OrdersServiceImpl implements OrdersService {
@Autowired
private OrdersDao ordersDao;
/**
* 查詢所有訂單
* @param pageNum
* @param pageSize
* @return
*/
@Override
public List<Orders> findAll(int pageNum,int pageSize) {
PageHelper.startPage(pageNum,pageSize);
return ordersDao.findAll();
}
}
二：解決方法：
一開始找了好多相關博客，大部分是說sql語句語法錯誤。
