Spring boot+mybatis+thymeleaf 實現(xiàn)登錄注冊增刪改查功能的示例代碼
更新時間：2020年07月15日 09:50:21 作者：狴顏丶領銜
這篇文章主要介紹了Spring boot+mybatis+thymeleaf 實現(xiàn)登錄注冊增刪改查功能的示例代碼,本文通過實例圖文相結(jié)合給大家介紹的非常詳細，對大家的學習或工作具有一定的參考借鑒價值，需要的朋友可以參考下
本文重在實現(xiàn)理解，過濾器，業(yè)務，邏輯需求，樣式請無視。。
項目結(jié)構(gòu)如下
1.idea新建Spring boot項目，在pom中加上thymeleaf和mybatis支持。pom.xml代碼如下
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.jz</groupId> <artifactId>table</artifactId> <version>0.0.1-SNAPSHOT</version> <name>table</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2. 在項目resources目錄下新建mybatis文件夾，用于存放mybatis配置文件。 在 application.properties 中配置本地數(shù)據(jù)源和mybatis配置文件地址, application.properties代碼如下
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/student?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC spring.datasource.username=用戶名 spring.datasource.password=密碼 spring.jpa.showSql=true mybatis: mybatis.type-aliases-package=com.jz.table.entity mybatis.mapper-locations=mybatis/*.xml
com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6中的，需要指定時區(qū)serverTimezone
2.2在啟動類上加上掃描的Dao包
package com.jz.table;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("com.jz.table.dao")
public class TableApplication {
public static void main(String[] args) {
SpringApplication.run(TableApplication.class, args);
}
}
3.數(shù)據(jù)庫建兩個表admin和userinfo用于登錄和操作用
2019.10.3 現(xiàn)在mysql不能用admin作為表名了，請注意一下
4.開始寫代碼
entity:實體代碼
1.Admin實體類
package com.jz.table.entity;
public class Admin {
private Integer id;
private String name;
private Integer password;
private String job;
public Admin() {
}
public Admin(Integer id, String name, Integer password, String job) {
this.id = id;
this.name = name;
this.password = password;
this.job = job;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getPassword() {
return password;
}
public void setPassword(Integer password) {
this.password = password;
}
public String getJob() {
return job;
}
public void setJob(String job) {
this.job = job;
}
}
2.UserInfo實體類
package com.jz.table.entity;
public class UserInfo {
private Integer id;
private String name;
private Integer age;
private String sex;
public UserInfo() {
}
public UserInfo(Integer id, String name, Integer age, String sex) {
this.id = id;
this.name = name;
this.age = age;
this.sex = sex;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}
Dao層代碼
1.AdminDao
package com.jz.table.dao;
import com.jz.table.entity.Admin;
public interface AdminDao {
//登錄判斷
Admin login(Admin admin);
//注冊
int addAdmin(Admin admin);
}
2.UserDao
package com.jz.table.dao;
import com.jz.table.entity.UserInfo;
import java.util.List;
public interface UserDao {
//查
List<UserInfo> findall();
//增
int adduser(UserInfo user);
//根據(jù)Id查，用于修改時頁面回顯數(shù)據(jù)
UserInfo findByid(Integer id);
//修改
int updateUser(UserInfo user);
//刪除
int delUser(Integer id);
}
3.XML文件，因為沒有業(yè)務邏輯，service省了，controller中直接引入dao
1.AdminMapper.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.jz.table.dao.AdminDao">
<select id="login" parameterType="com.jz.table.entity.Admin" resultType="com.jz.table.entity.Admin">
select name,job FROM admin WHERE name = #{name} AND password = #{password}
</select>
<insert id="addAdmin" parameterType="com.jz.table.entity.Admin">
INSERT INTO admin (name,password,job) VALUES (#{name},#{password},#{job});
</insert>
</mapper>
2.UserMapper.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.jz.table.dao.UserDao">
<select id="findall" resultType="com.jz.table.entity.UserInfo">
select * from userinfo
</select>
<insert id="adduser" parameterType="com.jz.table.entity.UserInfo">
INSERT INTO userinfo(name,age,sex) VALUES (#{name},#{age},#{sex})
</insert>
<select id="findByid" parameterType="java.lang.Integer" resultType="com.jz.table.entity.UserInfo">
SELECT * FROM userinfo where id = #{id}
</select>
<update id="updateUser" parameterType="com.jz.table.entity.UserInfo">
update userinfo SET name=#{name },age =#{age},sex=#{sex} WHERE id = #{id}
</update>
<delete id="delUser" parameterType="java.lang.Integer">
DELETE from userinfo WHERE id = #{id}
</delete>
</mapper>
4.頁面,在templates文件夾下新建public和user文件夾用來存放公共頁面和user操作頁面
public文件夾下新建成功、失敗提示頁
1.success.html
<!DOCTYPE html> <!--引入thymeleaf--> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>操作成功提示頁</title> </head> <body> <h1>操作成功</h1> <a href="/index" rel="external nofollow" rel="external nofollow" > 返回首頁</a> </body> </html>
2.false.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>操作失敗提示頁</title>
<script th:src="@{/js/jquery-1.8.0.min.js}"></script>
</head>
<body>
<h1>操作失敗，請檢查數(shù)據(jù)重試</h1>
<input onclick="history.go(-1)" type="button" value="返回">
</body>
</html>
4.2在templates文件夾下新建login和register頁面作為登錄和注冊頁面
1.login.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>首頁</title>
<style>
/*a標簽去下劃線和點擊不變色，div內(nèi)容居中*/
a{
text-decoration: none;
color: #333333;
}
#idiv{text-align: center;border-radius: 20px;
width: 300px;
height: 350px;
margin: auto;
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;}
</style>
</head>
<body>
<div id="idiv">
<form action="/gologin" method="post">
請輸入姓名<input id="name" name="name" required="required"><br><br>
請輸入密碼<input id="password" name="password" type="password" placeholder="僅支持正整數(shù)" required="required"><br><br>
<input type="submit" value="登錄"> <button> <a href="/goregister" rel="external nofollow" >注冊</a></button>
</form>
</div>
</body>
</html>
2.register.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>賬號注冊</title>
<script th:src="@{/js/jquery-1.8.0.min.js}"></script>
</head>
<body>
<h2>賬號注冊</h2>
請輸入姓名：<input type="text" id="name"/><br><br>
請輸入密碼：<input type="password" id="password" placeholder="僅支持整數(shù)" /><br><br>
請確認密碼：<input type="password" id="passwordTwo" placeholder="僅支持整數(shù)"/><br><br>
請選擇角色：<select id="job" style="width: 173px">
<option value="管理員">管理員</option>
</select><br><br>
<button onclick="register()">注冊</button>
</body>
<script>
function register() {
var name = $("#name").val();
var password1 = $("#password").val();
var password2 = $("#passwordTwo").val();
var job = $("#job").val();
if (Number(password1) == Number(password2)){
$.post("/register",{name:name,password:password1,job:job},function (res) {
if (res ==true){
alert("注冊成功");
window.location.href ="/login";
} else {
alert("注冊失敗，請檢查數(shù)據(jù)重試");
}
})
}else {
alert("兩次密碼不一致！");
}
}
</script>
</html>
3.controller中代碼
@Controller
public class TestController {
@Resource
private AdminDao ad;
@Resource
private UserDao ud;
@RequestMapping("/login")//主頁
public String index(){
return "login";
}
@RequestMapping("/goregister")//去注冊頁面
public String goregister(){
return "register";
}
@RequestMapping("/register")//注冊
@ResponseBody
public boolean register(Admin admin){
int i = ad.addAdmin(admin);
if (i>0){
return true;
}else {
return false;
}
}
@RequestMapping("/gologin")//登錄獲取用戶信息存到seccion
public String gologin(Admin admin,HttpServletRequest request,Model model){
Admin aa = ad.login(admin);
if (aa==null){
return "public/false";
}
HttpSession session = request.getSession();
session.setAttribute("aname",admin.getName());
session.setAttribute("apassword",admin.getPassword());
List<UserInfo> userlist = ud.findall();
model.addAttribute("admin",aa);
model.addAttribute("alist",userlist);
return "user/index";
}
@RequestMapping("/index")//從其他頁面操作后返回列表頁面（重復登錄）
public String login(Admin admin,Model model,HttpServletRequest request){
HttpSession session = request.getSession();
admin.setName((String) session.getAttribute("aname"));
admin.setPassword((Integer) session.getAttribute("apassword"));
Admin aa = ad.login(admin);
List<UserInfo> userlist = ud.findall();
model.addAttribute("admin",aa);
model.addAttribute("alist",userlist);
return "user/index";
}
}
4.3user文件夾下新建index,addUser,updateUser頁面，作為主頁，添加，修改頁面
1.index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
