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: {}
我的控制器课程:
@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.我会非常感激.

我想我忘了补充
@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.请帮忙.

我已经解决了.决定同时使用基于注释的配置和基于XML的配置.
只需添加我为所有人做的事情:
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();
}
}
然后将其包含在基于XML的配置中
<bean class="com.joinups.config.SocialApiConfig" />
感谢大家的指导,以得到正确的答案!非常感谢.你们好棒!
最佳答案
看来您没有声明Twitter类型的bean.
从spring documentation开始,我可以看到您需要以某种方式实例化Twitter.
尝试声明一个bean< bean id =“ twitter” factory-bean =“ twitterConnectionFactory” />具有实例化TwitterTemplate对象所需的正确参数
编辑:
这是通过xml进行的配置:
<bean id="twitter" factory-method="findPrimaryConnection"
factory-bean="connectionRepository" scope="request" depends-on="connectionRepository">
<constructor-arg value="org.springframework.social.twitter.api.Twitter" />
</bean>
