基于SSM框架搭建的分页查询增删改员工信息系统
前言
新人小白初学SSM框架，一步一步面向百度、面向复制黏贴编程调试出来，在这里分享给大家，有错的地方还希望提出来学习学习。这里可以移步个人博客
实现功能
- 验证码登录
- 登录权限拦截
- 分页查询
- 按多条件模糊查询
- 增删改

三、control类的编写
UserController
package com.controller;
import com.domain.PageBean;
import com.domain.User;
import com.service.impl.UserServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.SessionAttributes;
import javax.imageio.ImageIO;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.util.Map;
import java.util.Random;
/**
* @author 丁生
* controller层的页面控制跳转
*/
@Controller
@SessionAttributes("loginUser")
public class UserController {
@Autowired
private UserServiceImpl service;
@RequestMapping("findUserByPage")
public String findAll(@RequestParam Map<String,Object> map, Model model){
PageBean pb = new PageBean();
if(map.get("currentPage")==null){
pb.setCurrentPage(1);
}else{
pb.setCurrentPage(Integer.parseInt(map.get("currentPage").toString()));
}
if(map.get("name")!=null){
pb.setName(map.get("name").toString());
}else{
pb.setName("");
}
if(map.get("address")!=null){
pb.setAddress(map.get("address").toString());
}else{
pb.setAddress("");
}
if(map.get("email")!=null){
pb.setEmail(map.get("email").toString());
}else{
pb.setEmail("");
}
model.addAttribute("pb", service.findUserByPage(pb));
return "list";
};
@RequestMapping("checkCode")
public void checkCode(HttpServletRequest request, HttpServletResponse response) throws IOException {
//服务器通知浏览器不要缓存
response.setHeader("pragma","no-cache");
response.setHeader("cache-control","no-cache");
response.setHeader("expires","0");
//在内存中创建一个长80，宽30的图片，默认黑色背景
//参数一：长
//参数二：宽
//参数三：颜色
int width = 80;
int height = 30;
BufferedImage image = new BufferedImage(width,height,BufferedImage.TYPE_INT_RGB);
//获取画笔
Graphics g = image.getGraphics();
//设置画笔颜色为灰色
g.setColor(Color.GRAY);
//填充图片
g.fillRect(0,0, width,height);
//产生4个随机验证码，12Ey
String base = "0123456789ABCDEFGabcdefg";
int size = base.length();
Random r = new Random();
StringBuffer sb = new StringBuffer();
for(int i=1;i<=4;i++){
//产生0到size-1的随机值
int index = r.nextInt(size);
//在base字符串中获取下标为index的字符
char c = base.charAt(index);
//将c放入到StringBuffer中去
sb.append(c);
}
String checkCode = sb.toString();
System.out.println(checkCode);
//将验证码放入HttpSession中
request.getSession().setAttribute("CHECKCODE_SERVER",checkCode);
//设置画笔颜色为黄色
g.setColor(Color.YELLOW);
//设置字体的小大
g.setFont(new Font("黑体",Font.BOLD,24));
//向图片上写入验证码
g.drawString(checkCode,15,25);
//将内存中的图片输出到浏览器
//参数一：图片对象
//参数二：图片的格式，如PNG,JPG,GIF
//参数三：图片输出到哪里去
ImageIO.write(image,"PNG",response.getOutputStream());
}
@RequestMapping("login")
public String login(String username, String password, String verifycode, HttpSession session, Model model){
if("".equals(username)|| "".equals(password)|| "".equals(verifycode)){
model.addAttribute("error","请输入信息");
return "login";
}
if(!verifycode.equalsIgnoreCase(session.getAttribute("CHECKCODE_SERVER").toString())){
model.addAttribute("error","验证码错误");

}
User user = service.login(username, password);
if(user==null){

}
@RequestMapping("addUser")
public String addUser(User user){
service.add(user);
return "redirect:findUserByPage";
}
@RequestMapping("delUser")
public String delUser(String id){
service.delUser(id.toString());
return "redirect:findUserByPage";
}
@RequestMapping("delSelected")
public String delSelected(@RequestParam("uid") String[] ids){
for (String id : ids) {
service.delUser(id);
}
return "redirect:findUserByPage";
}
@RequestMapping("findUser")
public String findUser(String id, Model model){
User user = service.findUser(id);
model.addAttribute("u",user);
return "update";
}
@RequestMapping("update")
public String update(User user){
service.update(user);
return "redirect:findUserByPage";
}
}
LoginInterceptor
package com.controller;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* 权限拦截器
* @author 丁生
*/
public class LoginInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
Object user = request.getSession().getAttribute("loginUser");
if (user == null) {
response.sendRedirect("/login.jsp");
return false;
}
return true;
}
}
四、service类的编写
接口
package com.service;
import com.domain.PageBean;
import com.domain.User;
import java.util.List;
/**
* @author 丁生
*/
public interface UserService {
/**
* 按页查询
* @param
*/
public PageBean findUserByPage(PageBean pb);
/**
* 登录查询
*/
public User login(String username, String password);
/**
* 增加用户
*/
public void add(User user);
/**
* 删除用户
* @Param
*/
public void delUser(String id);
/**
* 按id查找用户
* @param id
* @return
*/
public User findUser(String id);
/**
* 更新用户信息
* @param user
*/
public void update(User user);
}
实现类
package com.service.impl;
import com.dao.UserDao;
import com.domain.PageBean;
import com.domain.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* @author 丁生
*/
@Service
public class UserServiceImpl implements com.service.UserService{
@Autowired
public UserDao dao;
@Override
public PageBean findUserByPage(PageBean pb) {
pb.setTotalCount(dao.findAll(pb));
pb.setRows(5);
int totalPage =((pb.getTotalCount()) % (pb.getRows())) == 0 ? (pb.getTotalCount())/(pb.getRows()) : (pb.getTotalCount())/(pb.getRows()) + 1;
pb.setTotalPage(totalPage);
if(pb.getCurrentPage() >= pb.getTotalPage()){
pb.setCurrentPage(pb.getTotalPage());
}
if(pb.getCurrentPage() <= 1){
pb.setCurrentPage(1);
}
pb.setStartIndex((pb.getCurrentPage()-1)*pb.getRows());
pb.setUsers(dao.findUserByPage(pb));
return pb;
}
@Override
public User login(String username, String password) {
return dao.login(username, password);
}
@Override
public void add(User user) {
dao.add(user);
}
@Override
public void delUser(String id) {
dao.delUser(id);
}
@Override
public User findUser(String id) {
return dao.findUser(id);
}
@Override
public void update(User user) {
dao.update(user);
}
}
五、dao层的编写
dao接口
package com.dao;
import com.domain.PageBean;
import com.domain.User;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* @author 丁生
*/
@Repository
public interface UserDao {
/**
* 查询所有
*/
public int findAll(PageBean pb);
/**
* 查询所有
*/
public List<User> findUserByPage(PageBean pb);
/**
* 登录
*/
public User login(@Param("username") String username, @Param("password") String password);
/**
* 添加
*/
public void add(User user);
/**
* 删除
*/
public void delUser(String id);
public User findUser(String id);
public void update(User user);
}
dao的查询配置文件 dao.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dao.UserDao">
<update id="update">

</update>
<select id="findAll" resultType="java.lang.Integer" parameterType="com.domain.PageBean">
select count(*) from user
<if test="name!=''">
where name like '%${name}%'
</if>
<if test="address!=''">

</if>
<if test="email!=''">

</if>
</select>
<select id="findUserByPage" resultType="com.domain.User" parameterType="com.domain.PageBean" >
select * from user

</if>
<if test="email!=''">

</if>
limit #{startIndex},#{rows}
</select>
<select id="login" resultType="com.domain.User" parameterType="java.lang.String">
select * from user where username = '${username}' and password = '${password}'
</select>
<select id="findUser" resultType="com.domain.User" parameterType="java.lang.String">
select * from user where id = '${id}'
</select>
<insert id="add">
insert into user
value (null,'${name}','${gender}','${age}','${address}','${qq}','${email}',null ,null )
</insert>
<delete id="delUser" parameterType="java.lang.String">
delete from user where id = '${id}'
</delete>
</mapper>
六、封装类
user
package com.domain;
import org.springframework.stereotype.Component;
import java.io.Serializable;
/**

*/
@Component
public class User implements Serializable {
private int id;

}
public void setName(String name) {

}
public String getGender() {
return gender;
}
public void setGender(String gender) {

}
public int getAge() {
return age;
}
public void setAge(int age) {

}
public String getAddress() {
return address;
}
public void setAddress(String address) {

}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User{" +

'}';
}
}
PageBean类
package com.domain;
import org.springframework.stereotype.Component;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
/**
* @author 丁生
*/
@Component
public class PageBean implements Serializable {
//总记录数
private int totalCount;
//总页数
private int totalPage;
//当前页数
private int currentPage;
//当前显示条数

public int getTotalCount() {
return totalCount;
}
public void setTotalCount(int totalCount) {
