我的Spring
Boot项目中有一个相当基本的设置。我正在尝试设置OAuth2来保护我的API，但是我遇到了/oauth/token端点问题。向我的/oauth/token端点发出POST或GET请求将导致以下响应（带有401 Unauthorized状态代码）：

{
    "timestamp": "2018-09-17T16:46:59.961+0000",
    "status": 401,
    "error": "Unauthorized",
    "message": "Unauthorized",
    "path": "/oauth/token"
}

这是我的授权服务器配置。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.approval.UserApprovalHandler;
import org.springframework.security.oauth2.provider.token.TokenStore;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private TokenStore tokenStore;

    @Autowired
    private UserApprovalHandler userApprovalHandler;

    @Autowired
    @Qualifier("authenticationManagerBean")
    private AuthenticationManager authenticationManager;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("client_id")
                .secret("secret")
                .authorizedGrantTypes("password", "authorization_code", "refresh_token")
                .scopes("read", "write")
                .accessTokenValiditySeconds(600)
                .refreshTokenValiditySeconds(3600);
    }

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

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) {
        security.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()")
                .passwordEncoder(this.passwordEncoder);
    }
}

这是我的资源服务器配置。尚无重要信息：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.TokenStore;

public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
    @Autowired
    private TokenStore tokenStore;

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources.tokenStore(this.tokenStore);
    }
}

最后是我的标准Web安全配置：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.approval.ApprovalStore;
import org.springframework.security.oauth2.provider.approval.TokenApprovalStore;
import org.springframework.security.oauth2.provider.approval.TokenStoreUserApprovalHandler;
import org.springframework.security.oauth2.provider.approval.UserApprovalHandler;
import org.springframework.security.oauth2.provider.request.DefaultOAuth2RequestFactory;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.InMemoryTokenStore;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private ClientDetailsService clientDetailsService;

    @Autowired
    public void globalUserDetails(AuthenticationManagerBuilder builder) throws Exception {
        builder.inMemoryAuthentication()
                .withUser("user").password("password").roles("ADMIN")
                .and()
                .withUser("admin").password("password").roles("USER");
    }

    @Override
    protected void configure(HttpSecurity security) throws Exception {
        security.csrf().disable()
                .anonymous().disable()
                .authorizeRequests()
                .antMatchers("/oauth/token").permitAll();
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(8);
    }

    @Bean
    @Autowired
    public UserApprovalHandler userApprovalHandler(TokenStore tokenStore) {
        TokenStoreUserApprovalHandler handler = new TokenStoreUserApprovalHandler();
        handler.setTokenStore(tokenStore);
        handler.setRequestFactory(new DefaultOAuth2RequestFactory(this.clientDetailsService));
        handler.setClientDetailsService(this.clientDetailsService);

        return handler;
    }

    @Bean
    @Autowired
    public ApprovalStore approvalStore(TokenStore tokenStore) {
        TokenApprovalStore store = new TokenApprovalStore();
        store.setTokenStore(tokenStore);

        return store;
    }
}

我已经用不同的匹配器模式弄乱了很多，以查看是否可以使它工作，但我没有任何运气。我在根上下文和上的servlet路径中运行此文件http://localhost:8080。

我可以确认，当Spring Boot启动时，端点已映射到输出中，尝试达到稍有不同的端点将导致预期的404。
