Spring Social Linkedin resourceaccessexception
我正在尝试使用社交 linkedin 进行个人资料简单搜索。我已经设置了我的配置和所有内容，但是当我尝试搜索时出现异常。这是我的代码：
context.xml:
<bean class="org.springframework.social.linkedin.connect.LinkedInServiceProvider">
<constructor-arg value="75........" /> // Api Token
<constructor-arg value="Fl2........" /> //secret
</bean>
我是这样使用的：
@Autowired LinkedInServiceProvider provider;
.........
LinkedIn ln = provider.getApi("AQW......."); //My accessToken
SearchParameters searchParameters = new SearchParameters();
searchParameters.setFirstName("firsname");
searchParameters.setLastName("lastname");
ln.profileOperations().search(searchParameters);
当我点击搜索时，出现异常：

知道我为什么会遇到这个异常吗？
我在代理后面。我通过添加应用程序参数解决了这个问题：
-Dhttp.proxyHost=代理-Dhttp.proxyPort=8080
