Mybatis+springmvc的分页pageHelper实现，及报错相关记录
PageHelper下载地址：https://oss.sonatype.org/content/repositories/releases/com/github/pagehelper/pagehelper/
先看看我的实现分页的主要代码
@Controller
public class HistoryController {
@Autowired
private Historyservice historyservice;
@RequestMapping("showHistory")
@ResponseBody
public PageInfo showHistory(@RequestParam("pageNum")int pageNum){
int pageSize=10;
//引入分页查询，使用PageHelper分页功能
//在查询之前传入当前页，然后多少记录
PageHelper.startPage(pageNum,pageSize,"htime DESC");
//startPage后紧跟的这个查询就是分页查询
List historylist=historyservice.showHisotory();
//使用PageInfo包装查询结果，只需要将pageInfo交给页面就可以
PageInfo pageInfo = new PageInfo(historylist);
return pageInfo;
}
} 
后来进行网上查阅，感谢各大网友的奉献精神!
发现自己并没有进行配置。所以接下来：
在mybatis-config.xml中配置一下内容：
视图为：
然后开始运行tomcat，出现错误：
错误内容如下：

那就是sql解析工具--jsqlparser.jar
4.1.0及以后版本需要0.9.4版本
http://repo1.maven.org/maven2/com/github/jsqlparser/jsqlparser/0.9.4/
4.1.0以前版本需要0.9.1版本
http://repo1.maven.org/maven2/com/github/jsqlparser/jsqlparser/0.9.1/
然后将下载的包添加进项目中:点击Add External JARs-》在自己文件中找到自己下载好的pageHelper.jar包-》Apply
最后成功的实现了排序分页，结果显示：
-----------------------------------------------华丽分割线----------------------------------------------------------
如果您在我之前所遇到的问题讲述没有看明白如何具体实现的，接下来我来总结一下。
一、需要下载两个jar包
1.PageHelper下载地址：https://oss.sonatype.org/content/repositories/releases/com/github/pagehelper/pagehelper/
（这个包的版本自己选择下载，里面也有pom等格式）
2.那就是sql解析工具--jsqlparser.jar
如果你下载的PageHelper4.1.0及以后版本需要jsqlparser0.9.4版本
http://repo1.maven.org/maven2/com/github/jsqlparser/jsqlparser/0.9.4/
如果你下载的PageHelper4.1.0以前版本需要jsqlparser0.9.1版本
http://repo1.maven.org/maven2/com/github/jsqlparser/jsqlparser/0.9.1/
然后两个包添加到项目中。
二、mybatis-config.xml中配置pageHelper的相关信息
三、代码中实现分页
That‘s ok！
