po包 
package zl.po;

public class User {

}
Mapper包

UserMapper.java（接口类）

package zl.mapper;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import zl.po.User;

public interface UserMapper {
	public User queryUserByUid(int uid);//根据用户编号查询用户信息，返回一个用户对象
	public List getAllUser();//获取所有用户信息
	public List queryByUname(String uname);//输入用户姓名，模糊查询用户
	public Integer addUser(User user);//添加用户
	public Integer deleteUser(int uid);//根据用户编号来删除用户
	public Integer updateUser(User user);//修改用户
}

UserMapper.xml




	
		select * from usertab
	
	
	
		insert into usertab(uid,uname,age) values(0,#{uname},#{age})
	
	
	
	
	delete from usertab where uid=#{_parameter}
	
	
	
	
	update usertab set uname=#{uname},age=#{age} where uid=#{uid}
UserService包

UserService.java（接口类）

package zl.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import zl.mapper.UserMapper;
import zl.po.User;

@Service
public interface UserService {
	public User queryUserByUid(int uid);//根据用户编号查询用户信息，返回一个用户对象
	public List getAllUser();//获取所有用户信息
	public List queryByUname(String uname);//输入用户姓名，模糊查询用户
	public Integer addUser(User user);//添加用户
	public Integer deleteUser(int uid);//根据用户编号来删除用户
	public Integer updateUser(User user);//修改用户
}

UserServiceimpl.java（实现类）

package zl.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import zl.mapper.UserMapper;
import zl.po.User;

@Service
public class UserServiceimpl implements UserService {
	@Autowired
	UserMapper userMapper;
	
	@Override
	public User queryUserByUid(int uid) {
		return userMapper.queryUserByUid(uid);
	}

	@Override
	public List getAllUser() {
		return userMapper.getAllUser();
	}

	@Override
	public List queryByUname(String uname) {
		return userMapper.queryByUname(uname);
	}

	@Override
	public Integer addUser(User user) {
		return userMapper.addUser(user);
	}

	@Override
	public Integer deleteUser(int uid) {
		return userMapper.deleteUser(uid);
	}

	@Override
	public Integer updateUser(User user) {
		return userMapper.updateUser(user);
	}
}
controller包

import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;

import zl.po.User;
import zl.service.UserService;

@Controller

	}

//分页查询
	@RequestMapping("/getAllUser")
	public String getAllUser(Model model,@RequestParam(defaultValue = "1") int pageNum,
			@RequestParam(defaultValue = "2") int pageSize) {// pageNum：第几页，pageSize：每页几条记录

	}
	
	@RequestMapping("/toAddUser")
	public String toAddUser() {//跳转到添加用户页面
