我创建了sling:配置文件夹中的OsgiConfig节点,如config.author,config.publish等。我试图通过这样的方式从这些节点获取属性:
public static List fetchTokenLinksFromOsgiConfig(final SlingHttpServletRequest slingRequest) throws IOException {
List<String> tokenlinksList = new ArrayList<String>();
SlingBindings bindings = (SlingBindings) slingRequest.getAttribute(SlingBindings.class.getName());
log.info("=================inside fetchTokenLinksFromOsgiConfig======================"+bindings);
SlingScriptHelper sling = bindings.getSling();
Configuration conf = sling.getService(org.osgi.service.cm.ConfigurationAdmin.class).getConfiguration("com.xxxxx.TokenLinksConfig");
log.info("=================inside fetchTokenLinksFromOsgiConfig:::taking configurations======================");
String TokenId = (String) conf.getProperties().get("TokenId");
String TokenSecret = (String) conf.getProperties().get("TokenSecret");
String OAuthLink = (String) conf.getProperties().get("OAuthLink");
log.info("=================TokenId:::TokenSecret:::OAuthLink======================"+TokenId +" "+TokenSecret+" "+OAuthLink);
if(!StringUtil.isEmpty(TokenId)) {
tokenlinksList.add(TokenId);
}
if(!StringUtil.isEmpty(TokenSecret)) {
tokenlinksList.add(TokenSecret);
}
if(!StringUtil.isEmpty(OAuthLink)) {
tokenlinksList.add(OAuthLink);
}
return tokenlinksList;
}
我从这样的吊索servlet中调用这个方法:
List tokenList = OsgiConfigUtil.fetchTokenLinksFromOsgiConfig(slingRequest);
但SlingBindings类型的bindings对象为null。我不知道如何解决这个问题?

答案 0 :(得分:1)
Sling servlet是一个OSGi组件,因此您可以使用SCR ConfigurationAdmin
注释直接注入@Reference
服务:
public MyServlet extends SlingSafeMethodServlet {
@Reference
private ConfigurationAdmin confAdmin;
public doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) {
confAdmin.getConfiguration("com.myuhc.TokenLinksConfig");
}
}
无需使用SlingBindings对象,该对象旨在在JSP脚本中提供OSGi服务。
