Spring Boot整合Spring Security简单实现登入登出从零搭建教程

前言

Spring Security是一个能够为基于Spring的企业应用系统提供声明式的安全访问控制解决方案的安全框架。它提供了一组可以在Spring应用上下文中配置的Bean，充分利用了Spring IoC，DI（控制反转Inversion of Control ,DI:Dependency Injection 依赖注入）和AOP（面向切面编程）功能，为应用系统提供声明式的安全访问控制功能，减少了为企业系统安全控制编写大量重复代码的工作。

本文主要给大家介绍了关于Spring Boot整合Spring Security实现登入登出的相关内容，下面话不多说了，来一起看看详细的介绍吧

技术栈 : SpringBoot + SpringSecurity + jpa + freemark ，完整项目地址 : https://github.com/EalenXie/spring-security-login （本地下载）

方法如下：

1 . 新建一个spring-security-login的maven项目，pom.xml添加基本依赖 :

<?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>

2 . 准备你的数据库，设计表结构，要用户使用登入登出，新建用户表。

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `user_uuid` varchar(70) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `username` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `email` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `telephone` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `role` int(10) DEFAULT NULL,
 `image` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `last_ip` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 `last_time` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
 PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

SET FOREIGN_KEY_CHECKS = 1;

3 . 用户对象User.java :

import javax.persistence.*;

/**
 * Created by EalenXie on 2018/7/5 15:17
 */
@Entity
@Table(name = "USER")
public class User {
 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private Integer id;
 private String user_uuid; //用户UUID
 private String username; //用户名
 private String password; //用户密码
 private String email; //用户邮箱
 private String telephone; //电话号码
 private String role; //用户角色
 private String image; //用户头像
 private String last_ip; //上次登录IP
 private String last_time; //上次登录时间

 public Integer getId() {
 return id;
 }

 public String getRole() {
 return role;
 }

 public void setRole(String role) {
 this.role = role;
 }

 public String getImage() {
 return image;
 }

 public void setImage(String image) {
 this.image = image;
 }

 public void setId(Integer id) {
 this.id = id;
 }


 public String getUsername() {
 return username;
 }

 public void setUsername(String username) {
 this.username = username;
 }

 public String getEmail() {
 return email;
 }

 public void setEmail(String email) {
 this.email = email;
 }

 public String getTelephone() {
 return telephone;
 }

 public void setTelephone(String telephone) {
 this.telephone = telephone;
 }

 public String getPassword() {
 return password;
 }

 public void setPassword(String password) {
 this.password = password;
 }

 public String getUser_uuid() {
 return user_uuid;
 }

 public void setUser_uuid(String user_uuid) {
 this.user_uuid = user_uuid;
 }

 public String getLast_ip() {
 return last_ip;
 }

 public void setLast_ip(String last_ip) {
 this.last_ip = last_ip;
 }

 public String getLast_time() {
 return last_time;
 }

 public void setLast_time(String last_time) {
 this.last_time = last_time;
 }

 @Override
 public String toString() {
 return "User{" +
 "id=" + id +
 ", user_uuid='" + user_uuid + '\'' +
 ", username='" + username + '\'' +
 ", password='" + password + '\'' +
 ", email='" + email + '\'' +
 ", telephone='" + telephone + '\'' +
 ", role='" + role + '\'' +
 ", image='" + image + '\'' +
 ", last_ip='" + last_ip + '\'' +
 ", last_time='" + last_time + '\'' +
 '}';
 }
}

4 . application.yml配置一些基本属性

spring:
 resources:
 static-locations: classpath:/
 freemarker:
 template-loader-path: classpath:/templates/
 suffix: .html
 content-type: text/html
 charset: UTF-8
 datasource:
 url: jdbc:mysql://localhost:3306/yourdatabase
 username: yourname
 password: yourpass
 driver-class-name: com.mysql.jdbc.Driver
 type: com.alibaba.druid.pool.DruidDataSource
server:
 port: 8083
 error:
 whitelabel:
 enabled: true

5 . 考虑我们应用的效率 , 可以配置数据源和线程池 :

package com.wuxicloud.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.pool.DruidDataSourceFactory;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.*;

import javax.sql.DataSource;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

@Configuration
public class DruidConfig {
 private static final String DB_PREFIX = "spring.datasource.";

 @Autowired
 private Environment environment;

 @Bean
 @ConfigurationProperties(prefix = DB_PREFIX)
 public DataSource druidDataSource() {
 Properties dbProperties = new Properties();
 Map<String, Object> map = new HashMap<>();
 for (PropertySource<?> propertySource : ((AbstractEnvironment) environment).getPropertySources()) {
 getPropertiesFromSource(propertySource, map);
 }
 dbProperties.putAll(map);
 DruidDataSource dds;
 try {
 dds = (DruidDataSource) DruidDataSourceFactory.createDataSource(dbProperties);
 dds.init();
 } catch (Exception e) {
 throw new RuntimeException("load datasource error, dbProperties is :" + dbProperties, e);
 }
 return dds;
 }

 private void getPropertiesFromSource(PropertySource<?> propertySource, Map<String, Object> map) {
 if (propertySource instanceof MapPropertySource) {
 for (String key : ((MapPropertySource) propertySource).getPropertyNames()) {
 if (key.startsWith(DB_PREFIX))
  map.put(key.replaceFirst(DB_PREFIX, ""), propertySource.getProperty(key));
 else if (key.startsWith(DB_PREFIX))
  map.put(key.replaceFirst(DB_PREFIX, ""), propertySource.getProperty(key));
 }
 }

 if (propertySource instanceof CompositePropertySource) {
 for (PropertySource<?> s : ((CompositePropertySource) propertySource).getPropertySources()) {
 getPropertiesFromSource(s, map);
 }
 }
 }

 @Bean
 public ServletRegistrationBean druidServlet() {
 return new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
 }

 @Bean
 public FilterRegistrationBean filterRegistrationBean() {
 FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
 filterRegistrationBean.setFilter(new WebStatFilter());
 filterRegistrationBean.addUrlPatterns("/*");
 filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
 return filterRegistrationBean;
 }
}

配置线程池 :

package com.wuxicloud.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;

@Configuration
@EnableAsync
public class ThreadPoolConfig {
 @Bean
 public Executor getExecutor() {
 ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
 executor.setCorePoolSize(5);//线程池维护线程的最少数量
 executor.setMaxPoolSize(30);//线程池维护线程的最大数量
 executor.setQueueCapacity(8); //缓存队列
 executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy()); //对拒绝task的处理策略
 executor.setKeepAliveSeconds(60);//允许的空闲时间
 executor.initialize();
 return executor;
 }
}

6.用户需要根据用户名进行登录，访问数据库 :

import com.wuxicloud.model.User;
import org.springframework.data.jpa.repository.JpaRepository;

/**
 * Created by EalenXie on 2018/7/11 14:23
 */
public interface UserRepository extends JpaRepository<User, Integer> {

 User findByUsername(String username);

}

7.构建真正用于SpringSecurity登录的安全用户(UserDetails)，我这里使用新建了一个POJO来实现 :

package com.wuxicloud.security;

import com.wuxicloud.model.User;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.ArrayList;
import java.util.Collection;

public class SecurityUser extends User implements UserDetails {
 private static final long serialVersionUID = 1L;

 public SecurityUser(User user) {
 if (user != null) {
 this.setUser_uuid(user.getUser_uuid());
 this.setUsername(user.getUsername());
 this.setPassword(user.getPassword());
 this.setEmail(user.getEmail());
 this.setTelephone(user.getTelephone());
 this.setRole(user.getRole());
 this.setImage(user.getImage());
 this.setLast_ip(user.getLast_ip());
 this.setLast_time(user.getLast_time());
 }
 }

 @Override
 public Collection<? extends GrantedAuthority> getAuthorities() {
 Collection<GrantedAuthority> authorities = new ArrayList<>();
 String username = this.getUsername();
 if (username != null) {
 SimpleGrantedAuthority authority = new SimpleGrantedAuthority(username);
 authorities.add(authority);
 }
 return authorities;
 }

 @Override
 public boolean isAccountNonExpired() {
 return true;
 }

 @Override
 public boolean isAccountNonLocked() {
 return true;
 }

 @Override
 public boolean isCredentialsNonExpired() {
 return true;
 }

 @Override
 public boolean isEnabled() {
 return true;
 }
}

8 . 核心配置，配置SpringSecurity访问策略，包括登录处理，登出处理，资源访问，密码基本加密。

package com.wuxicloud.config;

import com.wuxicloud.dao.UserRepository;
import com.wuxicloud.model.User;
import com.wuxicloud.security.SecurityUser;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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.core.Authentication;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler;
import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * Created by EalenXie on 2018/1/11.
 */
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
 private static final Logger logger = LoggerFactory.getLogger(WebSecurityConfig.class);

 @Override
 protected void configure(HttpSecurity http) throws Exception { //配置策略
 http.csrf().disable();
 http.authorizeRequests().
 antMatchers("/static/**").permitAll().anyRequest().authenticated().
 and().formLogin().loginPage("/login").permitAll().successHandler(loginSuccessHandler()).
 and().logout().permitAll().invalidateHttpSession(true).
 deleteCookies("JSESSIONID").logoutSuccessHandler(logoutSuccessHandler()).
 and().sessionManagement().maximumSessions(10).expiredUrl("/login");
 }

 @Autowired
 public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
 auth.userDetailsService(userDetailsService()).passwordEncoder(passwordEncoder());
 auth.eraseCredentials(false);
 }

 @Bean
 public BCryptPasswordEncoder passwordEncoder() { //密码加密
 return new BCryptPasswordEncoder(4);
 }

 @Bean
 public LogoutSuccessHandler logoutSuccessHandler() { //登出处理
 return new LogoutSuccessHandler() {
 @Override
 public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
 try {
  SecurityUser user = (SecurityUser) authentication.getPrincipal();
  logger.info("USER : " + user.getUsername() + " LOGOUT SUCCESS ! ");
 } catch (Exception e) {
  logger.info("LOGOUT EXCEPTION , e : " + e.getMessage());
 }
 httpServletResponse.sendRedirect("/login");
 }
 };
 }

 @Bean
 public SavedRequestAwareAuthenticationSuccessHandler loginSuccessHandler() { //登入处理
 return new SavedRequestAwareAuthenticationSuccessHandler() {
 @Override
 public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
 User userDetails = (User) authentication.getPrincipal();
 logger.info("USER : " + userDetails.getUsername() + " LOGIN SUCCESS ! ");
 super.onAuthenticationSuccess(request, response, authentication);
 }
 };
 }
 @Bean
 public UserDetailsService userDetailsService() { //用户登录实现
 return new UserDetailsService() {
 @Autowired
 private UserRepository userRepository;

 @Override
 public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
 User user = userRepository.findByUsername(s);
 if (user == null) throw new UsernameNotFoundException("Username " + s + " not found");
 return new SecurityUser(user);
 }
 };
 }
}

9.至此，已经基本将配置搭建好了，从上面核心可以看出，配置的登录页的url 为/login，可以创建基本的Controller来验证登录了。

package com.wuxicloud.web;

import com.wuxicloud.model.User;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
 * Created by EalenXie on 2018/1/11.
 */
@Controller
public class LoginController {

 @RequestMapping(value = "/login", method = RequestMethod.GET)
 public String login() {
 return "login";
 }

 @RequestMapping("/")
 public String root() {
 return "index";
 }

 public User getUser() { //为了session从获取用户信息,可以配置如下
 User user = new User();
 SecurityContext ctx = SecurityContextHolder.getContext();
 Authentication auth = ctx.getAuthentication();
 if (auth.getPrincipal() instanceof UserDetails) user = (User) auth.getPrincipal();
 return user;
 }

 public HttpServletRequest getRequest() {
 return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
 }
}

11 . SpringBoot基本的启动类 Application.class

package com.wuxicloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by EalenXie on 2018/7/11 15:01
 */
@SpringBootApplication
public class Application {

 public static void main(String[] args) {
 SpringApplication.run(Application.class, args);
 }
}

11.根据Freemark和Controller里面可看出配置的视图为 /templates/index.html和/templates/index.login。所以创建基本的登录页面和登录成功页面。

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>用户登录</title>
</head>
<body>
<form action="/login" method="post">
 用户名 : <input type="text" name="username"/>
 密码 : <input type="password" name="password"/>
 <input type="submit" value="登录">
</form>
</body>
</html>

注意 : 这里方法必须是POST，因为GET在controller被重写了，用户名的name属性必须是username，密码的name属性必须是password

index.html

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>首页</title>
 <#assign user=Session.SPRING_SECURITY_CONTEXT.authentication.principal/>
</head>
<body>
欢迎你,${user.username}<br/>
<a href="/logout">注销</a>
</body>
</html>

注意 : 为了从session中获取到登录的用户信息，根据配置SpringSecurity的用户信息会放在Session.SPRING_SECURITY_CONTEXT.authentication.principal里面，根据FreeMarker模板引擎的特点，可以通过这种方式进行获取 : <#assign user=Session.SPRING_SECURITY_CONTEXT.authentication.principal/>

12 . 为了方便测试，我们在数据库中插入一条记录，注意，从WebSecurity.java配置可以知道密码会被加密，所以我们插入的用户密码应该是被加密的。

这里假如我们使用的密码为admin，则加密过后的字符串是 $2a$04$1OiUa3yEchBXQBJI8JaMyuKZNlwzWvfeQjKAHnwAEQwnacjt6ukqu

　测试类如下 :

package com.wuxicloud.security;

import org.junit.Test;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

/**
 * Created by EalenXie on 2018/7/11 15:13
 */
public class TestEncoder {

 @Test
 public void encoder() {
 String password = "admin";
 BCryptPasswordEncoder encoder = new BCryptPasswordEncoder(4);
 String enPassword = encoder.encode(password);
 System.out.println(enPassword);
 }
}

测试登录，从上面的加密的密码我们插入一条数据到数据库中。

INSERT INTO `USER` VALUES (1, 'd242ae49-4734-411e-8c8d-d2b09e87c3c8', 'EalenXie', '$2a$04$petEXpgcLKfdLN4TYFxK0u8ryAzmZDHLASWLX/XXm8hgQar1C892W', 'SSSSS', 'ssssssssss', 1, 'g', '0:0:0:0:0:0:0:1', '2018-07-11 11:26:27');

13 . 启动项目进行测试，访问 localhost:8083

点击登录，登录失败会留在当前页面重新登录，成功则进入index.html

登录如果成功，可以看到后台打印登录成功的日志 :

页面进入index.html :

点击注销，则回重新跳转到login.html，后台也会打印登出成功的日志 :
