本文介绍了如何通过XML配置Spring Social的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我花了几个小时尝试使用XML配置方法使Twitter集成与Spring Social一起使用.我可以在网上(以及在stackoverflow上)找到的所有示例始终使用@Config方法，如

令我困惑的是connectionRepository实例运行得很好(我注释掉了twitter bean并测试了代码！)?！?它使用相同的功能:请求范围和接口AOP代理可以工作，但是twitter bean实例化失败吗?

spring社交配置代码如下(我看不到任何区别，对吗?):

@Configuration
public class SocialConfig {

    @Inject
    private Environment environment;

    @Inject
    private DataSource dataSource;

    @Bean
    @Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
    public ConnectionFactoryLocator connectionFactoryLocator() {
        ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
        registry.addConnectionFactory(new TwitterConnectionFactory(environment.getProperty("twitter.consumerKey"),
                environment.getProperty("twitter.consumerSecret")));
        return registry;
    }

    @Bean
    @Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
    public UsersConnectionRepository usersConnectionRepository() {
        return new JdbcUsersConnectionRepository(dataSource, connectionFactoryLocator(), Encryptors.noOpText());
    }

    @Bean
    @Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)   
    public ConnectionRepository connectionRepository() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication == null) {
            throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
        }
        return usersConnectionRepository().createConnectionRepository(authentication.getName());
    }

    @Bean
    @Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)   
    public Twitter twitter() {
        Connection<Twitter> twitter = connectionRepository().findPrimaryConnection(Twitter.class);
        return twitter != null ? twitter.getApi() : new TwitterTemplate();
    }

    @Bean
    public ConnectController connectController() {
        ConnectController connectController = new ConnectController(connectionFactoryLocator(), connectionRepository());
        connectController.addInterceptor(new PostToWallAfterConnectInterceptor());
        connectController.addInterceptor(new TweetAfterConnectInterceptor());
        return connectController;
    }

    @Bean
    public ProviderSignInController providerSignInController(RequestCache requestCache) {
        return new ProviderSignInController(connectionFactoryLocator(), usersConnectionRepository(), new SimpleSignInAdapter(requestCache));
    }
}

任何帮助/指针将不胜感激！

解决方案

我有一个适用于Spring Social Facebook集成的配置. (我有twitter配置，但尚未测试twitter部分)

<bean class="org.springframework.social.connect.web.ProviderSignInController">
<!-- relies on by-type autowiring for the constructor-args -->    
<constructor-arg ref="signInAdapter" /> 
</bean>

<bean id="connectionFactoryLocator" 
  class="org.springframework.social.connect.support.ConnectionFactoryRegistry">
<property name="connectionFactories">
    <list>
        <bean class="org.springframework.social.twitter.connect.TwitterConnectionFactory">
            <constructor-arg value="${twitter.consumerKey}" />
            <constructor-arg value="${twitter.consumerSecret}" />               
        </bean>
        <bean class="org.springframework.social.facebook.connect.FacebookConnectionFactory">
            <constructor-arg value="${facebook.clientId}" />
            <constructor-arg value="${facebook.clientSecret}" />                
        </bean>
    </list>
</property>
</bean>

<bean id="connectionRepository" factory-method="createConnectionRepository" 
  factory-bean="usersConnectionRepository" scope="request">
<constructor-arg value="#{request.userPrincipal.name}" />
<aop:scoped-proxy proxy-target-class="false" />
</bean>

<bean id="signInAdapter" class="com.test.social.SimpleSignInAdapter"/>

<bean id="usersConnectionRepository" 
  class="org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository">
<constructor-arg ref="dataSource" />
<constructor-arg ref="connectionFactoryLocator" />
<constructor-arg ref="textEncryptor" />
</bean>

<bean id="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors" 
        factory-method="noOpText" />

我主要参考了文档足够小，可以阅读，并且samples

For whatever reason the bean definition to get an instance to the twitter API throws an AOP exception: 

Caused by: java.lang.IllegalStateException: Cannot create scoped proxy for bean 'scopedTarget.twitter': Target type could not be determined at the time of proxy creation.

Here's the complete config file I have:

    <bean id="signInAdapter" class="com.sap.netweaver.cloud.demo.social.SimpleSignInAdapter" />

</beans>

What puzzles me is that the connectionRepositoryinstantiation works perfectly fine (I commented-out the twitter bean and tested the code!) ?!? It uses the same features: request scope and interface AOP proxy and works, but the twitter bean instantiation fails ?!?

The spring social config code looks as follows (I can not see any differences, can you?):

@Configuration
public class SocialConfig {

    @Inject
    private Environment environment;

    @Inject
    private DataSource dataSource;

    @Bean
    @Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
    public ConnectionFactoryLocator connectionFactoryLocator() {
        ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
        registry.addConnectionFactory(new TwitterConnectionFactory(environment.getProperty("twitter.consumerKey"),
                environment.getProperty("twitter.consumerSecret")));
        return registry;
    }

    @Bean
    @Scope(value="singleton", proxyMode=ScopedProxyMode.INTERFACES) 
    public UsersConnectionRepository usersConnectionRepository() {
        return new JdbcUsersConnectionRepository(dataSource, connectionFactoryLocator(), Encryptors.noOpText());
    }

    @Bean
    @Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)   
    public ConnectionRepository connectionRepository() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication == null) {
            throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
        }
        return usersConnectionRepository().createConnectionRepository(authentication.getName());
    }

    @Bean
    @Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)   
    public Twitter twitter() {
        Connection<Twitter> twitter = connectionRepository().findPrimaryConnection(Twitter.class);
        return twitter != null ? twitter.getApi() : new TwitterTemplate();
    }

    @Bean
    public ConnectController connectController() {
        ConnectController connectController = new ConnectController(connectionFactoryLocator(), connectionRepository());
        connectController.addInterceptor(new PostToWallAfterConnectInterceptor());
        connectController.addInterceptor(new TweetAfterConnectInterceptor());
        return connectController;
    }

    @Bean
    public ProviderSignInController providerSignInController(RequestCache requestCache) {
        return new ProviderSignInController(connectionFactoryLocator(), usersConnectionRepository(), new SimpleSignInAdapter(requestCache));
    }
}

Any help/pointers would be appreciated!!!

解决方案

I have a configuration that worked for Spring Social Facebook integration. (I have twitter configuration in it, But I haven't tested the twitter part in it)

<bean class="org.springframework.social.connect.web.ProviderSignInController">
<!-- relies on by-type autowiring for the constructor-args -->    
<constructor-arg ref="signInAdapter" /> 
</bean>

<bean id="connectionFactoryLocator" 
  class="org.springframework.social.connect.support.ConnectionFactoryRegistry">
<property name="connectionFactories">
    <list>
        <bean class="org.springframework.social.twitter.connect.TwitterConnectionFactory">
            <constructor-arg value="${twitter.consumerKey}" />
            <constructor-arg value="${twitter.consumerSecret}" />               
        </bean>
        <bean class="org.springframework.social.facebook.connect.FacebookConnectionFactory">
            <constructor-arg value="${facebook.clientId}" />
            <constructor-arg value="${facebook.clientSecret}" />                
        </bean>
    </list>
</property>
</bean>

<bean id="connectionRepository" factory-method="createConnectionRepository" 
  factory-bean="usersConnectionRepository" scope="request">
<constructor-arg value="#{request.userPrincipal.name}" />
<aop:scoped-proxy proxy-target-class="false" />
</bean>

<bean id="signInAdapter" class="com.test.social.SimpleSignInAdapter"/>

<bean id="usersConnectionRepository" 
  class="org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository">
<constructor-arg ref="dataSource" />
<constructor-arg ref="connectionFactoryLocator" />
<constructor-arg ref="textEncryptor" />
</bean>

<bean id="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors" 
        factory-method="noOpText" />

I have primarily referred the documentation which is small enough to read and a tutorial which had more to do with integration with spring security. I hope this helps in some way.
