**4.创建PageBean**

public class PageBean {
        
    
    	private Integer currentPage=1;
    	private Integer pageSize=5;
    	private Integer totalPage;
    	private Long totalCount;
    	
    	public Integer getCurrentPage() {
        
    		return currentPage;
    	}
    
    	public void setCurrentPage(Integer currentPage) {
        
    		this.currentPage = currentPage;
    	}
    
    	public Integer getPageSize() {
        
    		return pageSize;
    	}
    
    	public void setPageSize(Integer pageSize) {
        
    		this.pageSize = pageSize;
    	}
    
    	public Integer getTotalPage() {
        
    		return totalPage;
    	}
    
    	public void setTotalPage(Integer totalPage) {
        
    		this.totalPage = totalPage;
    	}
    
    	public Long getTotalCount() {
        
    		return totalCount;
    	}
    
    	public void setTotalCount(Long totalCount) {
        
    		this.totalCount = totalCount;
    		this.totalPage=(int) Math.ceil(this.totalCount*1.0/this.pageSize);
    	}
    	
    	
    	
    }

5.创建FolderService

8.创建WEB-INF/view/folder/list.jsp

## 2.添加修改删除 ##

**1.修改FolderController**

/**

    	 */
    	@RequestMapping("toAddFolder")
    	public String toAddFolder(){
        
    		return "folder/add";

    		User user=(User) session.getAttribute("user");
    		folderVo.setUid(user.getUid());
    		this.folderService.addFolder(folderVo);
    		return "redirect:loadAllFolder.action";
    	}
    	
    	/**
    	 * 跳转到修改页面
    	 */
    	@RequestMapping("toUpdateFolder")
    	public String toUpdateFolder(FolderVo folderVo){
        
    		Folder folder=this.folderService.queryFolderById(folderVo.getTid());

    		return "folder/update";
    	}
    	
    	/**

    	@RequestMapping("updateFolder")
    	public String updateFolder(FolderVo folderVo){
        
    		this.folderService.updateFolder(folderVo);
    		return "redirect:loadAllFolder.action";
