SpringBoot?Security使用MySQL實現驗證與權限管理
更新時間：2022年11月07日 17:05:07 作者：allway2
安全管理是軟件系統(tǒng)必不可少的的功能。根據經典的“墨菲定律”——凡是可能，總會發(fā)生。如果系統(tǒng)存在安全隱患，最終必然會出現問題，這篇文章主要介紹了SpringBoot安全管理Spring?Security基本配置
在本教程中，我將指導您如何編寫代碼，以使用具有基于表單的身份驗證的Spring安全API來保護Spring Boot應用程序中的網頁。用戶詳細信息存儲在MySQL數據庫中，并使用春季JDBC連接到數據庫。我們將從本教程中的 ProductManager 項目開始，向現有的彈簧啟動項目添加登錄和注銷功能。
1. 創(chuàng)建用戶表和虛擬憑據
憑據應存儲在數據庫中，因此讓我們創(chuàng)建新表，表間關系ER圖如下：
-- -------------------------------------------------------- -- 主機: 127.0.0.1 -- 服務器版本: 8.0.22 - MySQL Community Server - GPL -- 服務器操作系統(tǒng): Win64 -- HeidiSQL 版本: 12.1.0.6537 -- -------------------------------------------------------- /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;

USE `product3`; -- 導出 表 product3.permission 結構 CREATE TABLE IF NOT EXISTS `permission` ( `id` int NOT NULL AUTO_INCREMENT, `name` varchar(30) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL, `description` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT NULL, `uri` varchar(8192) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT NULL, `method` varchar(50) COLLATE utf8mb4_unicode_ci DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

-- 導出 表 product3.urls 結構 CREATE TABLE IF NOT EXISTS `urls` ( `name` varchar(500) COLLATE utf8mb4_unicode_ci NOT NULL, `description` varchar(500) COLLATE utf8mb4_unicode_ci DEFAULT NULL, PRIMARY KEY (`name`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

2. 配置數據源屬性
接下來，在應用程序屬性文件中指定數據庫連接信息，如下所示：根據您的MySQL數據庫更新URL，用戶名和密碼。
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/product3?autoReconnect=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root
#logging.level.root=WARN
3. 聲明彈簧安全性和MySQL JDBC驅動程序的依賴關系
要將Spring安全API用于項目，請在pom.xml文件中聲明以下依賴項：并且要將JDBC與彈簧啟動和MySQL一起使用：請注意，依賴項版本已由彈簧啟動初學者父項目定義。

</project>4. 配置 JDBC 身份驗證詳細信息
要將 Spring 安全性與基于表單的身份驗證和 JDBC 結合使用，請按如下方式創(chuàng)建WebSecurityConfig類：
package com.example;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private DataSource dataSource;
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Autowired
public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
authBuilder.jdbcAuthentication()
.dataSource(dataSource)
.passwordEncoder(new BCryptPasswordEncoder())
.usersByUsernameQuery("select username, password, enabled from user where username=?")
.authoritiesByUsernameQuery("SELECT user.username,permission.name FROM user,role,user_role,permission,role_permission WHERE user.id=user_role.user_id AND role.id=user_role.role_id AND role.id=role_permission.role_id AND permission.id=role_permission.permission_id AND user.username=?");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/common/**").permitAll()
.antMatchers("/login").permitAll()
.antMatchers("/logout").permitAll()
.antMatchers("/verify").permitAll()
.anyRequest()
.access("@rbacService.hasPermission(request , authentication)")
.and()
.formLogin().loginPage("/login")
.permitAll()
.and()
.logout().permitAll()
.and()
.exceptionHandling().accessDeniedPage("/403");
}
}此安全配置類必須使用@EnableWebSecurity注釋進行批注，并且是Web 安全配置器適配器的子類。數據源對象的實例將由Spring框架創(chuàng)建并注入：
@Autowired
private DataSource dataSource;它將從應用程序屬性文件中讀取數據庫連接信息。要使用JDBC配置身份驗證，請編寫以下方法：
@Autowired
public void configAuthentication(AuthenticationManagerBuilder authBuilder) throws Exception {
authBuilder.jdbcAuthentication()
.dataSource(dataSource)
.passwordEncoder(new BCryptPasswordEncoder())
.usersByUsernameQuery("select username, password, enabled from users where username=?")
.authoritiesByUsernameQuery("SELECT users.username,permissions.name FROM users,roles,users_roles,permissions,roles_permissions WHERE users.username=users_roles.username AND roles.name=users_roles.role_name AND roles.name=roles_permissions.role_name AND permissions.name=roles_permissions.permission AND users.username=?");
}如您所見，我們需要指定密碼編碼器（建議使用BCrypt），數據源和兩個SQL語句：第一個根據用戶名選擇用戶，第二個選擇用戶的角色。請注意，Spring安全性要求列名必須是用戶名，密碼，啟用和角色。為了配置基于表單的身份驗證，我們重寫了 configure（HttpSecurity）方法，如下所示：
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/edit/*", "/delete/*").hasAnyAuthority("ADMIN")
.anyRequest().authenticated()
.and()
.formLogin().permitAll()
.and()
.logout().permitAll()
.and()
.exceptionHandling().accessDeniedPage("/403");
}在這里，我們指定所有請求都必須進行身份驗證，這意味著用戶必須登錄才能使用該應用程序。使用Spring安全性提供的默認登錄表單。要顯示已登錄用戶的用戶名，請在Thymeleaf模板文件中編寫以下代碼：
<div sec:authorize="isAuthenticated()">
Welcome <b><span sec:authentication="name">Username</span></b>
<i><span sec:authentication="principal.authorities">Roles</span></i>
</div>并添加注銷按鈕：
<form th:action="@{/logout}" method="post">
<input type="submit" value="Logout" />
</form>如您所見，Spring Security將處理應用程序的登錄和注銷。我們不必編寫重復的代碼，只需指定一些配置即可。
5. 自定義登錄驗證過程
package com.example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.security.core.context.SecurityContextHolder;
import static org.springframework.security.web.context.HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY;
@Controller
public class LoginController {

@Autowired

}

public String login(@RequestParam("username") String username,
@RequestParam("password") String password,
@RequestParam("verifyCode") String verifyCode,
HttpSession session) {
System.out.println("username is:" + username);
System.out.println("password is:" + password);
System.out.println("verifyCode is:" + verifyCode);
if (StringUtils.isEmpty(verifyCode)) {
session.setAttribute("errorMsg", "The verification code cannot be empty");
return "login";
}
if (StringUtils.isEmpty(username) || StringUtils.isEmpty(password)) {
session.setAttribute("errorMsg", "User name or password cannot be empty");
return "login";
}
String kaptchaCode = session.getAttribute("verifyCode") + "";
System.out.println("kaptchaCode is:" + kaptchaCode);
if (StringUtils.isEmpty(kaptchaCode) || !verifyCode.equals(kaptchaCode)) {
session.setAttribute("errorMsg", "Verification code error");
return "login";
}
// User user = userService.login(userName, password);
System.out.println(username + "==" + password + "==" + verifyCode);
// 創(chuàng)建用戶名與密碼認證對象
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
try {
// 調用認證方法，返回認證對象
Authentication authenticate = authenticationManager.authenticate(token);
// 判斷是否認證成功
if (authenticate.isAuthenticated()) {
// 設置用戶認證成功，往Session中添加認證通過信息
SecurityContextHolder.getContext().setAuthentication(authenticate);
SecurityContext sc = SecurityContextHolder.getContext();
sc.setAuthentication(authenticate);
session.setAttribute(SPRING_SECURITY_CONTEXT_KEY, sc);
// 重定向到登錄成功頁面
return "redirect:/";
} else {
session.setAttribute("errorMsg", "Login failed");
return "login";
}
} catch (Exception ex) {
ex.printStackTrace();
}
return "login";
}

現在輸入正確的用戶名admin和密碼admin，您將看到主頁如下：
并注意歡迎消息后跟用戶名。用戶現在已通過身份驗證以使用該應用程序。單擊“注銷”按鈕，您將看到自定義的登錄頁面出現，這意味著我們已成功實現登錄并注銷到我們的Spring Boot應用程序。
