概要
之前的两篇文章,讲述了Spring Security 结合 OAuth2 、JWT 的使用,这一节要求对 OAuth2、JWT 有了解,若不清楚,先移步到下面两篇提前了解下。
Spring Boot Security 整合 OAuth2 设计安全API接口服务
Spring Boot Security 整合 JWT 实现 无状态的分布式API接口
这一篇我们来实现 支持 JWT令牌 的授权服务器。
优点
使用 OAuth2 是向认证服务器申请令牌,客户端拿这令牌访问资源服务服务器,资源服务器校验了令牌无误后,如果资源的访问用到用户的相关信息,那么资源服务器还需要根据令牌关联查询用户的信息。
使用 JWT 是客户端通过用户名、密码 请求服务器获取 JWT,服务器判断用户名和密码无误之后,可以将用户信息和权限信息经过加密成 JWT 的形式返回给客户端。在之后的请求中,客户端携带 JWT 请求需要访问的资源,如果资源的访问用到用户的相关信息,那么就直接从JWT中获取到。
所以,如果我们在使用 OAuth2 时结合JWT ,就能节省集中式令牌校验开销,实现无状态授权认证。

WebSecurityConfig
@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.
authorizeRequests().antMatchers("/**").permitAll();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password("123456").roles("USER");
}
@Bean
@Override

return super.authenticationManagerBean();
}
@Bean
public PasswordEncoder passwordEncoder() {
return new PasswordEncoder() {
@Override

return charSequence.toString();
}
@Override
public boolean matches(CharSequence charSequence, String s) {
return Objects.equals(charSequence.toString(),s);
}
};
}
}
为了方便,使用内存模式,在内存中创建一个用户 user 密码 123456。

application.yml
server:
port: 8081
security:
oauth2:
resource:
jwt:
key-value: test-secret
参数说明:
- security.oauth2.resource.jwt.key-value:设置签名key 保持和授权服务器一致。
- security.oauth2.resource.jwt:项目启动过程中,检查到配置文件中有
security.oauth2.resource.jwt 的配置,就会生成 jwtTokenStore 的 bean,对令牌的校验就会使用 jwtTokenStore 。
验证
请求令牌
curl -X POST --user 'clientapp:123' -d 'grant_type=password&username=user&password=123456' http://localhost:8080/oauth/token
返回JWT令牌
