我正在使用 Spring Social 连接到 Twitter。连接部分工作正常,但是当我尝试获取朋友列表时,出现以下错误:
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.springframework.social.twitter.api.Twitter] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
我的控制器类:
@Controller
@RequestMapping("/social")
public class SocialController {
private final Twitter twitter;
@Inject
public SocialController(Twitter twitter) {
this.twitter = twitter;
}
@RequestMapping(value="/twitter/friends", method=RequestMethod.GET)
public String friends(Model model) {
model.addAttribute("profiles", twitter.friendOperations().getFriends());
return "twitter/friends";
}
}
我的 XML 配置如下:(仅显示相关部分)
<!-- Spring Social -->
<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="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors"
factory-method="noOpText" />
<bean id="usersConnectionRepository"
class="org.springframework.social.connect.jdbc.JdbcUsersConnectionRepository">
<constructor-arg ref="jpaDataSource" />
<constructor-arg ref="connectionFactoryLocator" />
<constructor-arg ref="textEncryptor" />
</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 class="org.springframework.social.connect.web.ConnectController">
<!-- relies on by-type autowiring for the constructor-args -->
<property name="applicationUrl" value="${application.url}" />
</bean>
<!-- Spring Social -->
请指导。我会非常感谢。

我想我忘了添加
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Twitter twitter() {
Connection<Twitter> twitter = connectionRepository().findPrimaryConnection(Twitter.class);
return twitter != null ? twitter.getApi() : new TwitterTemplate();
}
到 XML 文件。任何想法如何在 XML 上下文中表示。我是基于注释的配置的新手,因此使用基于 xml 的配置。请帮忙。

我解决了一个解决方法。决定同时使用基于注释的配置和基于 XML 的配置。只需添加我为每个人所做的事情:
我添加了一个配置:
public class SocialApiConfig {
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Facebook facebook(ConnectionRepository connectionRepository) {
Connection<Facebook> facebook = connectionRepository.findPrimaryConnection(Facebook.class);
return facebook != null ? facebook.getApi() : new FacebookTemplate();
}
@Bean
@Scope(value="request", proxyMode=ScopedProxyMode.INTERFACES)
public Twitter twitter(ConnectionRepository connectionRepository) {
Connection<Twitter> twitter = connectionRepository.findPrimaryConnection(Twitter.class);
return twitter != null ? twitter.getApi() : new TwitterTemplate();
}
}
然后将其包含在我的基于 XML 的配置中
<bean class="com.joinups.config.SocialApiConfig" />
感谢大家指导我得到正确答案!非常感谢。你们真棒!
