Spring Security + JWT 实现单点登录
作者 | 波波烤鸭
本文我们来看下 SpringSecurity + JWT 实现单点登录操作,本文 2W 字,预计阅读时间 30 min,文章提供了代码骨架,建议收藏。
一、什么是单点登陆
单点登录(Single Sign On),简称为 SSO,是目前比较流行的企业业务整合的解决方案之一。SSO的定义是在多个应用系统中,用户只需要登录一次就可以访问所有相互信任的应用系统
二、简单的运行机制
单点登录的机制其实是比较简单的,用一个现实中的例子做比较。某公园内部有许多独立的景点,游客可以在各个景点门口单独买票。
对于需要游玩所有的景点的游客,这种买票方式很不方便,需要在每个景点门口排队买票,钱包拿 进拿出的,容易丢失,很不安全。
于是绝大多数游客选择在大门口买一张通票(也叫套票),就可以玩遍所有的景点而不需要重新再买票。他们只需要在每个景点门 口出示一下刚才买的套票就能够被允许进入每个独立的景点。
单点登录的机制也一样,如下图所示,
用户认证: 这一环节主要是用户向认证服务器发起认证请求,认证服务器给用户返回一个成功的令牌token,主要在认证服务器中完成,即图中的认证系统,注意认证系统只能有一个。
身份校验: 这一环节是用户携带token去访问其他服务器时,在其他服务器中要对token的真伪进行检验,主要在资源服务器中完成,即图中的应用系统2 3
三、JWT介绍
概念说明
从分布式认证流程中,我们不难发现,这中间起最关键作用的就是token,token的安全与否,直接关系到系统的健壮性,这里我们选择使用JWT来实现token的生成和校验。
JWT,全称JSON Web Token,官网地址https://jwt.io,是一款出色的分布式身份校验方案。可以生成token,也可以解析检验token。
JWT生成的token由三部分组成:
头部:主要设置一些规范信息,签名部分的编码格式就在头部中声明。 载荷:token中存放有效信息的部分,比如用户名,用户角色,过期时间等,但是不要放密码,会泄露! 签名:将头部与载荷分别采用base64编码后,用“.”相连,再加入盐,最后使用头部声明的编码类型进行编码,就得到了签名。
JWT生成token的安全性分析
从JWT生成的token组成上来看,要想避免token被伪造,主要就得看签名部分了,而签名部分又有三部分组成,其中头部和载荷的base64编码,几乎是透明的,毫无安全性可言,那么最终守护token安全的重担就落在了加入的盐上面了!
如果您正在学习Spring Boot,推荐一个连载多年还在继续更新的免费教程:http://blog.didispace.com/spring-boot-learning-2x/
试想:如果生成token所用的盐与解析token时加入的盐是一样的。岂不是类似于中国人民银行把人民币防伪技术公开了?大家可以用这个盐来解析token,就能用来伪造token。这时,我们就需要对盐采用非对称加密的方式进行加密,以达到生成token与校验token方所用的盐不一致的安全效果!
非对称加密RSA介绍
基本原理: 同时生成两把密钥:私钥和公钥,私钥隐秘保存,公钥可以下发给信任客户端
私钥加密,持有私钥或公钥才可以解密 公钥加密,持有私钥才可解密
优点: 安全,难以破解
缺点: 算法比较耗时,为了安全,可以接受
历史: 三位数学家Rivest、Shamir 和 Adleman 设计了一种算法,可以实现非对称加密。这种算法用他们三个人的名字缩写:RSA。
四、SpringSecurity整合JWT
1.认证思路分析
SpringSecurity主要是通过过滤器来实现功能的!我们要找到SpringSecurity实现认证和校验身份的过滤器!
回顾集中式认证流程
用户认证: 使用UsernamePasswordAuthenticationFilter
过滤器中attemptAuthentication
方法实现认证功能,该过滤器父类中successfulAuthentication
方法实现认证成功后的操作。
身份校验: 使用BasicAuthenticationFilter
过滤器中doFilterInternal
方法验证是否登录,以决定能否进入后续过滤器。
分析分布式认证流程
用户认证:
由于分布式项目,多数是前后端分离的架构设计,我们要满足可以接受异步post的认证请求参数,需要修改UsernamePasswordAuthenticationFilter
过滤器中attemptAuthentication
方法,让其能够接收请求体。
另外,默认successfulAuthentication
方法在认证通过后,是把用户信息直接放入session就完事了,现在我们需要修改这个方法,在认证通过后生成token并返回给用户。
身份校验:
原来BasicAuthenticationFilter过滤器中doFilterInternal方法校验用户是否登录,就是看session中是否有用户信息,我们要修改为,验证用户携带的token是否合法,并解析出用户信息,交给SpringSecurity,以便于后续的授权功能可以正常使用。
2.具体实现
为了演示单点登录的效果,我们设计如下项目结构
2.1父工程创建
因为本案例需要创建多个系统,所以我们使用maven聚合工程来实现,首先创建一个父工程,导入springboot的父依赖即可
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.3.RELEASE</version>
<relativePath/>
</parent>
2.2公共工程创建
然后创建一个common工程,其他工程依赖此系统
导入JWT相关的依赖

@Test
public void test1() throws Exception{

}
}
2.3认证系统创建
接下来我们创建我们的认证服务。

public class UserServiceImpl implements UserService {
@Autowired
private UserMapper mapper;
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {

return user;
}
}
自定义认证过滤器
public class TokenLoginFilter extends UsernamePasswordAuthenticationFilter {
private AuthenticationManager authenticationManager;
private RsaKeyProperties prop;
public TokenLoginFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
this.authenticationManager = authenticationManager;
this.prop = prop;

resultMap.put("msg", "用户名或密码错误!");
out.write(new ObjectMapper().writeValueAsString(resultMap));
out.flush();
out.close();
}catch (Exception outEx){

}
throw new RuntimeException(e);
}
}
public void successfulAuthentication(HttpServletRequest request, HttpServletResponse response, FilterChain chain, Authentication authResult) throws IOException, ServletException {
UserPojo user = new UserPojo();
user.setUsername(authResult.getName());
user.setRoles((List<RolePojo>)authResult.getAuthorities());
String token = JwtUtils.generateTokenExpireInMinutes(user, prop.getPrivateKey(), 24 * 60);
response.addHeader("Authorization", "Bearer "+token);

resultMap.put("msg", "认证通过!");
out.write(new ObjectMapper().writeValueAsString(resultMap));
out.flush();
out.close();
}catch (Exception outEx){

}
}
}
自定义校验token的过滤器
public class TokenVerifyFilter extends BasicAuthenticationFilter {
private RsaKeyProperties prop;
public TokenVerifyFilter(AuthenticationManager authenticationManager, RsaKeyProperties prop) {
super(authenticationManager);
this.prop = prop;
}
public void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {
String header = request.getHeader("Authorization");
if (header == null || !header.startsWith("Bearer ")) {
//如果携带错误的token,则给用户提示请登录!
chain.doFilter(request, response);
response.setContentType("application/json;charset=utf-8");
response.setStatus(HttpServletResponse.SC_FORBIDDEN);
PrintWriter out = response.getWriter();
Map resultMap = new HashMap();
resultMap.put("code", HttpServletResponse.SC_FORBIDDEN);
resultMap.put("msg", "请登录!");
out.write(new ObjectMapper().writeValueAsString(resultMap));
out.flush();
out.close();
} else {
//如果携带了正确格式的token要先得到token
String token = header.replace("Bearer ", "");
//验证tken是否正确
Payload<UserPojo> payload = JwtUtils.getInfoFromToken(token, prop.getPublicKey(), UserPojo.class);
UserPojo user = payload.getUserInfo();
if(user!=null){
UsernamePasswordAuthenticationToken authResult = new UsernamePasswordAuthenticationToken(user.getUsername(), null, user.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(authResult);
chain.doFilter(request, response);
}
}
}
}
编写SpringSecurity的配置类
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled=true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserService userService;
@Autowired
private RsaKeyProperties prop;
@Bean
public BCryptPasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
//指定认证对象的来源
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService).passwordEncoder(passwordEncoder());
}
//SpringSecurity配置信息
public void configure(HttpSecurity http) throws Exception {
http.csrf()
.disable()
.authorizeRequests()
.antMatchers("/user/query").hasAnyRole("ADMIN")
.anyRequest()
.authenticated()
.and()
.addFilter(new TokenLoginFilter(super.authenticationManager(), prop))
.addFilter(new TokenVerifyFilter(super.authenticationManager(), prop))
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
}
启动服务测试
启动服务
通过Postman来访问测试
根据token信息我们访问其他资源
2.4资源系统创建
说明
资源服务可以有很多个,这里只拿产品服务为例,记住,资源服务中只能通过公钥验证认证。不能签发token!创建产品服务并导入jar包根据实际业务导包即可,咱们就暂时和认证服务一样了。
另外,如果您正在学习Spring Cloud,推荐一个连载多年还在继续更新的免费教程:https://blog.didispace.com/spring-cloud-learning/
接下来我们再创建一个资源服务
导入相关的依赖

编写产品服务配置文件
切记这里只能有公钥地址!
server:
port: 9002
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/srm

mapper-locations: classpath:mapper/*.xml
logging:
level:
com.dpb: debug
rsa:
key:
pubKeyFile: c:\tools\auth_key\id_key_rsa.pub
编写读取公钥的配置类
@Data
@ConfigurationProperties(prefix = "rsa.key")
public class RsaKeyProperties {
private String pubKeyFile;
private PublicKey publicKey;
/**
* 系统启动的时候触发
* @throws Exception
*/
@PostConstruct
public void createRsaKey() throws Exception {
publicKey = RsaUtils.getPublicKey(pubKeyFile);
}
}
编写启动类
@SpringBootApplication
@MapperScan("com.dpb.mapper")
@EnableConfigurationProperties(RsaKeyProperties.class)
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class,args);
}
}
复制认证服务中,用户对象,角色对象和校验认证的接口
复制认证服务中的相关内容即可
复制认证服务中SpringSecurity配置类做修改
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled=true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private UserService userService;
@Autowired
private RsaKeyProperties prop;
@Bean
public BCryptPasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
//指定认证对象的来源
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService).passwordEncoder(passwordEncoder());
}
//SpringSecurity配置信息
public void configure(HttpSecurity http) throws Exception {
http.csrf()
.disable()
.authorizeRequests()
//.antMatchers("/user/query").hasAnyRole("USER")
.anyRequest()
.authenticated()
.and()
.addFilter(new TokenVerifyFilter(super.authenticationManager(), prop))
// 禁用掉session
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
}
去掉“增加自定义认证过滤器”即可!
编写产品处理器
@RestController
@RequestMapping("/user")
public class UserController {
@RequestMapping("/query")
public String query(){
return "success";
}
@RequestMapping("/update")
public String update(){
return "update";
}
}
