六、applicationContext.xml配置

八、各层代码的实现：
1、实体类pojo：
Person

public class Person implements Serializable {
	private int pid;
	private String pname;
//	年龄
	private int page;
	
	public int getPid() {
		return pid;
	}
	public void setPid(int pid) {
		this.pid = pid;
	}
	public String getPname() {
		return pname;
	}
	public void setPname(String pname) {
		this.pname = pname;
	}
	public int getPage() {
		return page;
	}
	public void setPage(int page) {
		this.page = page;
	}
	public Person() {
	}
	public Person(int pid, String pname, int page) {
		super();
		this.pid = pid;
		this.pname = pname;
		this.page = page;
	}
	@Override
	public String toString() {
		return "Person [pid=" + pid + ", pname=" + pname + ", page=" + page
				+ "]";
	}
}

PageBean.java

/**
 * 分页Model类
 * @author 
 *
 */
public class PageBean {
	/**
	 * 总记录数
	 */
	private int total;
	/**
	 * 总页数
	 */
	private int totalPage;
	private int page; // 第几页
	private int pageSize; // 每页记录数
	private int start;  // 起始页
	
	
	public int getTotal() {
		return total;
	}
	public void setTotal(int total) {
		this.total = total;
	}
//	计算总页数
	public int getTotalPage() {
		return total%pageSize==0?total/pageSize:(total/pageSize+1);
	}
	public void setTotalPage(int totalPage) {
		this.totalPage = totalPage;
	}
	public PageBean(int page, int pageSize) {
		super();
		this.page = page;
		this.pageSize = pageSize;
	}
	
	public int getPage() {
		return page;
	}
	public void setPage(int page) {
		this.page = page;
	}
	
	public int getPageSize() {
		return pageSize;
	}

	public void setPageSize(int pageSize) {
		this.pageSize = pageSize;
	}

	public int getStart() {
		return (page-1)*pageSize;
	}
	@Override
	public String toString() {
		return "PageBean [total=" + total + ", totalPage=" + totalPage
				+ ", page=" + page + ", pageSize=" + pageSize + ", start="
				+ start + "]";
	}
}

2、mapper：
接口：PersonMapper.java

public interface PersonMapper {
	public List getAll();
	public void add(Person person);
	public void delete(int pid);
	public Person getById(int pid);
	public void update(Person person);
		//分页
	public List findPage(Map map);
	public Long getTotal();
}

映射mapper：PersonMapper.xml

	
	
		select * from person
	
	
		insert into person(pname,page) values(#{pname},#{page})

	
	
		delete from person where pid=#{pid}
	
	
		select * from person where pid=#{pid}
	
	
		update person set pname=#{pname}, page=#{page} where pid=#{pid}
	
	
		select count(*) from person
	
		
		select * from person limit #{start},#{size}
	

	
		select count(*) from person
	
 

3、service层：
接口：PersonService.java

public interface PersonService {
	public List getAll();
	public void add(Person person);
	public void delete(int pid);
	public Person getById(int pid);
	public void update(Person person);
	public List findPage(Map map);
	
	public Long getTotal();
}

实现类：

//将service实现交给springIOC管理
@Service(value="personServiceImpl")
public class PersonServiceImpl implements PersonService{
	
	@Resource
	private PersonMapper personMapper;
	
	@Override
	public List getAll() {
		return personMapper.getAll();
	}

	@Override
	public void add(Person person) {
		personMapper.add(person);
	}

	@Override
	public void delete(int pid) {
		personMapper.delete(pid);
	}

	@Override
	public Person getById(int pid) {
		return personMapper.getById(pid);
	}

	@Override
	public void update(Person person) {
		personMapper.update(person);
	}
		@Override
	public List findPage(Map map) {
		return personMapper.findPage(map);
	}

	@Override
	public Long getTotal() {
		return personMapper.getTotal();
	}

}

4、controller控制器：
PersonController.java

@Controller
public class PersonController {
	@Resource
	private PersonService personService;
		@RequestMapping("/list")
	public String list(@RequestParam(value = "page", required = false,defaultValue="1")String page,ModelMap datamap){
//		if (page == null || page.equals("")) {
//			page = "1";
//		}
		//每页显示条数
		int pagesize=2;
		PageBean pageBean = new PageBean(Integer.parseInt(page), pagesize);
//		获得数据总条数
		long total = personService.getTotal();
//		将总数set进页面对象
		pageBean.setTotal(Integer.parseInt(total + ""));
		
		Map map = new HashMap();
		map.put("start", pageBean.getStart());
		map.put("size", pageBean.getPageSize());
		List list = personService.findPage(map);
		System.out.println("pageBean："+pageBean);
		System.out.println("list："+list);
		datamap.put("page", pageBean);
		datamap.put("list", list);

		return "forward:/list.jsp";
	} 
	@RequestMapping("/getall")
	public String getAll(ModelMap datamap) {
		List list = personService.getAll();
		
		datamap.put("list", list);
		//return "forward:/list.jsp";
		return "list";

	}
	
	@RequestMapping("/add")
	public String add(Person p) {
		personService.add(p);
		return "redirect:/getall";

	}
	
	@RequestMapping("/delete")
	public String delete(int pid) {
		personService.delete(pid);
		return "redirect:/getall";
	}
	
	@RequestMapping("/getbyid")
	public String getById(int pid, ModelMap map) {
		Person p = personService.getById(pid);
		map.put("person", p);
		//return "forward:/update.jsp";
		return "update";
	}
	
	@RequestMapping("/update")
	public String update(Person p) {
		personService.update(p);
		return "redirect:/getall";
	}
}

九、前端页面的：
1、index.jsp

 
  <%response.sendRedirect("getall"); %>
  

2、list.jsp

	添加
	
			

		

			
编号
			
姓名
			
年龄
			
操作
		
		

				
${person.pid }
				
${person.pname }
				
${person.page }
				
删除 修改
			
		
	
	

		总页数：${page.totalPage } 当前页：${page.page }
		
			首页
			上一页
		
		
			下一页
			末页
		
	

3、add.jsp

  
  

  姓名:

 年龄:

 
  
  
  

4、update.jsp
