【问题描述】：

我有以下依赖项：

compile('org.springframework.boot:spring-boot-starter-web')
testCompile('org.springframework.boot:spring-boot-starter-test')
compile group: 'org.springframework.security.oauth', name: 'spring-security-oauth2', version: '2.0.2.RELEASE'

及以下来源（复制自http://www.baeldung.com/sso-spring-security-oauth2）：

主要：

@SpringBootApplication
@EnableResourceServer
public class AuthorizationServerApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(AuthorizationServerApplication.class, args);
    }
}

AuthServerConfig：

@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("SampleClientId")
                .secret("secret")
                .authorizedGrantTypes("authorization_code")
                .scopes("user_info")
                .autoApprove(true) ;
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }
}

安全配置：

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.requestMatchers()
                .antMatchers("/login", "/oauth/authorize")
                .and()
                .authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .formLogin().permitAll();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.parentAuthenticationManager(authenticationManager)
                .inMemoryAuthentication()
                .withUser("john").password("123").roles("USER");
    }
}

用户控制器：

@RestController
public class UserController {
    @GetMapping("/user/me")
    public Principal user(Principal principal) {
        return principal;
    }
}

当我启动应用程序时，我看到以下内容：

我做错了什么？

附言
我在库中找到了这些类，但在另一个包中：

org.springframework.security.config.annotation.authentication.configuration

但是 spring 试图在包中找到它：

org.springframework.security.config.annotation.authentication.configurers

【问题讨论】：

标签： java spring-boot spring-security spring-security-oauth2


【解决方案1】：

您的其他一些依赖项可能依赖于 Spring Security 4（该类位于与 Spring Security 5 不同的包中）。

我遇到了同样的问题。就我而言，它是 activiti-spring-boot-starter-basic (6.0.0)。

【讨论】：

  • 将 activiti-spring-boot-starter-basic 升级到 6.0.0 是否解决或导致了您的问题？
  • 这是一个错误的原因。我想将项目升级到 Spring Boot 2。然后似乎 Activity 6 不支持 Spring Boot 2。我们必须等待升级（我们仍然这样做）到 Activity 7。
【解决方案2】：

尝试将此依赖项添加到您的 pom.xml 文件中

<dependency>
      <groupId>org.springframework.security</groupId>
     <artifactId>spring-security-config</artifactId>
     <version>4.2.12.RELEASE</version>
</dependency>

【讨论】：

    【解决方案3】：

    你必须有相同的版本。如果你有 2.2.5 版本的 spring，你必须有 2.2.5 的 spring 安全版本。

    【讨论】：

      【解决方案4】：

      我在使用旧版本的 activiti 时遇到了同样的问题。使用 Spring Security 5 更改 pom.xml 依赖项对我有用

          <dependency>
        <groupId>org.activiti</groupId>
        <artifactId>activiti-spring-boot-starter</artifactId>
        <version>7.1.0.M6</version>
    </dependency>
