我有一个Spring MVC应用程序,它使用Spring Social Facebook来启用Facebook登录。这在我的本地计算机上运行正常,但它目前在我的暂存环境中不起作用。我的问题是我无法弄清楚出了什么问题。当我尝试登录时,我被重定向到Facebook以授权该应用程序。这部分工作正常。但是当我授权该应用时,所有发生的事情都是我被重定向回http://example.com/signin?error=provider#_=_
,这会产生404 Not Found
错误。
这对于调试错误源并不是很有用,查看我的Tomcat日志文件,我找不到任何可以帮助我找到错误的信息。没有堆栈跟踪,错误消息等。我在我的项目中启用了log4j,但是我没有看到来自Spring Social的任何日志。实际上我不确定如何配置Spring Social的日志记录,但我在 log4j2.xml 文件中尝试了以下内容:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="com.example" level="trace">
<AppenderRef ref="Console" />
</Logger>
<Logger name="org.springframework.social" level="all">
<AppenderRef ref="Console" />
</Logger>
<Logger name="org.springframework.social.facebook" level="all">
<AppenderRef ref="Console" />
</Logger>
<Logger name="org.springframework.social.security" level="all">
<AppenderRef ref="Console" />
</Logger>
<Root level="error">
<AppenderRef ref="Console" />
</Root>
</Loggers>
</Configuration>
但是,我在控制台中看不到任何Spring Social日志。如果我在我的应用程序中写入它,如下所示,日志记录工作正常,因此日志记录应该正常工作。
@Controller
public class IndexController {
private static Logger logger = LogManager.getLogger(IndexController.class);
@RequestMapping("/")
public String home() {
logger.debug("Hello there from logger!");
return "home";
}
}
如何为Spring Social配置日志记录?我发现了一些按照我的方式配置log4j的示例(例如one used for Spring Social tests),但没有其他任何内容。我想库支持这个,因为否则我不知道如何调试错误。或者有没有其他方法可以找出触发错误的内容?
以下是我的Spring Social配置,即使我认为在这种情况下不重要。
@Configuration
public class SocialConfig {
@Autowired
private DataSource dataSource;
@Autowired
private TextEncryptor textEncryptor;
@Autowired
private AccountService accountService;
@Autowired
private AccountRepository accountRepository;
@Value("${facebook.app.id}")
private String facebookAppId;
@Value("${facebook.app.secret}")
private String facebookAppSecret;
@Bean
public ProviderSignInController providerSignInController() {
ProviderSignInController controller = new ProviderSignInController(this.connectionFactoryLocator(), this.usersConnectionRepository(), new SpringSecuritySignInAdapter(this.accountRepository));
controller.addSignInInterceptor(new RedirectToPreviousPageInterceptor(controller));
return controller;
}
@Bean
public ConnectionFactoryRegistry connectionFactoryLocator() {
ConnectionFactoryRegistry connectionFactoryRegistry = new ConnectionFactoryRegistry();
List<ConnectionFactory<?>> connectionFactories = new ArrayList<ConnectionFactory<?>>();
connectionFactories.add(this.facebookConnectionFactory());
connectionFactoryRegistry.setConnectionFactories(connectionFactories);
return connectionFactoryRegistry;
}
@Bean
public FacebookConnectionFactory facebookConnectionFactory() {
FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(this.facebookAppId, this.facebookAppSecret);
connectionFactory.setScope("email");
return connectionFactory;
}
@Bean
public JdbcUsersConnectionRepository usersConnectionRepository() {
JdbcUsersConnectionRepository repository = new JdbcUsersConnectionRepository(this.dataSource, this.connectionFactoryLocator(), this.textEncryptor);
repository.setConnectionSignUp(this.accountService);
return repository;
}
}
非常感谢你。

经过大量的试验和错误,我设法解决了这个问题。原来我的项目依赖项不正确,Spring Framework的日志记录没有通过slf4j正确发送到log4j。我使用了以下Maven依赖项:
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.5</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
<version>2.2</version>
</dependency>
然后我使用问题中发布的log4j2.xml
启用了Spring Framework的日志记录,并将其隐藏在十亿日志中,我发现了以下内容:

正如您所看到的,它是由密钥长度太长引起的,因为JDK由于政治原因,默认情况下仅默认支持128位加密。为了解决这个问题,我遵循了this SO question的建议。我在this excellent blog post的详细信息中对此进行了解释。对于OS X,JAVA_HOME
位于/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
,因此您可以将文件粘贴到/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/jre/lib/security
。出现此问题是因为我在开发计算机上使用了noOpText
文本加密器,当我将应用程序移动到登台环境时,我将应用程序设置为使用querable text encryptor。确保密钥长度不再限制为128位后,我必须将userconnection
表的accesstoken
列的长度增加到varchar(255)
。那就是它!它现在可以正常工作。
我希望这可以帮助处于类似情况的人。
