Spring Social Linkedin - SignIn

Question

我是Spring社交的新手，正在尝试为linkedin配置spring社交登录。

下面是我的spring配置文件，

<context:component-scan base-package="com.tc.web">
<context:include-filter type="regex"
expression="(service|controller|component)\..*" />
</context:component-scan>

<bean id="connectionFactoryLocator"
class="org.springframework.social.connect.support. ConnectionFactoryRegistry">
<property name="connectionFactories">
<list>
<bean
class="org.springframework.social.linkedin.connect .LinkedInConnectionFactory">
<constructor-arg value="key........" />
<constructor-arg value="secret .........." />
</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.Jdb cUsersConnectionRepository">
<constructor-arg ref="dataSource" />
<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 id="signInAdapter" class="com.tc.web.social.signin.SocialSignInAdapte r" />

<bean class="org.springframework.social.connect.web.Prov iderSignInController">
<!-- relies on by-type autowiring for the constructor-args -->
<constructor-arg ref="signInAdapter" />
<property name="applicationUrl" value="link" />
<property name="signUpUrl" value="link" />
<property name="signInUrl" value="link" />
</bean>

我的SocialSignInAdapter.java是

公共类SocialSignInAdapter实现了SignInAdapter{

@Override
public String signIn(String userId, Connection<?> connection, NativeWebRequest request) {
System.out.println("User Id is ===>>> "+userId);
System.out.println("Connection is ====>>> "+connection);
return null;
}

}

在Login.jsp中，

<li class="linkedin"><a href="${pageContext.request.contextPath}/signin/linkedin" title="LinkedIn">&nbsp;</a></li>

当我点击上面的linkedin链接时，我得到404错误。

我猜我的应用程序找不到请求的ProviderSignInController ://dom:8080/myApp/signin/linkedin。

我怀疑spring xml中的以下配置。

<context:component-scan base-package="com.tc.web">
<context:include-filter type="regex"
expression="(service|controller|component)\..*" />
</context:component-scan>

我把我所有的控制器都放在com.tc.web包中。但是ProviderSignInController在Spring包中，我的应用程序无法找到它。

我也尝试了下面的方法。

<context:component-scan base-package="com.tc.web,org.springframework.social.con nect.web">
<context:include-filter type="regex"
expression="(service|controller|component)\..*" />
</context:component-scan>

在上面的配置中，我得到了ProviderSignInController的模糊映射错误。因此，我删除了

<bean class="org.springframework.social.connect.web.Prov iderSignInController">
<!-- relies on by-type autowiring for the constructor-args -->
<constructor-arg ref="signInAdapter" />
<property name="applicationUrl" value="link" />
<property name="signUpUrl" value="link" />
<property name="signInUrl" value="link" />
</bean>

来自我的spring xml。但我仍然收到404错误。

有人能在这方面帮我忙吗..........

谢谢，Baskar.S

处理登录请求的控制器是org.springframework.social.connect.web.ProviderSignInController (出现在spring-social-web-x.jar中)，控制器方法是

@RequestMapping(value="/{providerId}", method=RequestMethod.POST)
public RedirectView signIn(@PathVariable String providerId, NativeWebRequest request)

因此，正如您所看到的，它只接受POST请求。您必须将锚链接标记更改为触发表单提交的按钮。例如：

<form action="<c:url value="/signin/linkedin" />" method="POST" id="frmLiConnect"></form>

其次，为了使用Spring Controller，使用您自己的虚拟控制器扩展ProviderSignInController，这样Spring类就可以访问了。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.social.connect.ConnectionFactoryLocator;
import org.springframework.social.connect.UsersConnectionRepository;
import org.springframework.social.connect.web.ProviderSignInController;
import org.springframework.social.connect.web.SignInAdapter;
import org.springframework.stereotype.Controller;
@Controller
public class SigninController extends ProviderSignInController {

@Autowired
public SigninController(ConnectionFactoryLocator connectionFactoryLocator,
        UsersConnectionRepository usersConnectionRepository,
        SignInAdapter signInAdapter) {
    super(connectionFactoryLocator, usersConnectionRepository, signInAdapter);
    // TODO Auto-generated constructor stub
}

}

有关更多详细信息，您还可以参考以下链接中的Spring Social Showcase示例。https://github.com/spring-projects/spring-social-samples/tree/master/spring-social-showcase/src/main/java/org/springframework/social/showcase/signin

希望这能有所帮助。
