在使用dubbo前，代码如下

//分页，每页一个
PageHelper.startPage(pageNum,1);
List<Homework> homeworks = homeworkService.selectByQuestionId(questionId);
PageInfo<Homework> info=new PageInfo<Homework>(homeworks,5);

把web项目做成分布式后，所有内容都显示在一个页面，只有一个页面，并没有进行分页。

于是改了一下Service

public PageInfo<Homework> selectByQuestionId(String questionId, int pageNum, int pageSize,int subscriptNum) {
  //分页，每页一个
  PageHelper.startPage(pageNum,pageSize);
  List<Homework> homeworks = selectByQuestionId(questionId);
  PageInfo<Homework> info=new PageInfo<Homework>(homeworks,subscriptNum);
  return info;
 }

然后Controller调用一下新方法就解决了。

PageInfo<Homework> info= homeworkService.selectByQuestionId(questionId, pageNum, 1, 5);
