我放置在以下路径中的jar文件：

/opt/tomcat7/webapps/share/WEB-INF/lib

除“我的自定义计算器”外，所有操作都非常完美。在此配置中，共享不起作用。。。在日志中，我看到以下内容：

[aleksey@alfresco01 tomcat7]$ sudo vi share.log

如果在evaluator中，我实现了

ActionEvaliator

界面，并尝试按如下方式识别当前用户

public class UsersCompareEvaluator implements ActionEvaluator  {

    private Map<Object, Object> registeredBeans = 
        Context.getProcessEngineConfiguration().getBeans();
    private ServiceRegistry registry = 
        (ServiceRegistry)registeredBeans.get(ActivitiConstants.SERVICE_REGISTRY_BEAN_KEY);
    private AuthenticationService authenticationService = 
        registry.getAuthenticationService();  

    @Override
    public boolean evaluate(Node node) {
        System.out.println("CURRENT USER IS ... " + 
            authenticationService.getCurrentUserName());

        return true;
    }

    @Override
    public boolean evaluate(Object object) {
        if(object instanceof Node) {
            return evaluate((Node)object);
        } 

        return false;
    }
}

我试图将自定义计算器打包到单独的jar中，并将其放在这里：

/opt/tomcat7/webapps/alfresco/WEB-INF/lib

。但我如何从共享中引用此评估者

例如，我有一个单独的项目（

alf221 custom evaluator

）：

在

alf221 custom evaluator slingshot application context.xml中，我指定以下内容：

我的自定义计算器不工作
如何为Alfresco 4.2.2中的共享编写自定义评估器
我将非常感谢您提供的信息。感谢大家。
看来我已经找到了解决方案。。。问题是我使用了Alfresco库中的BaseEvaluator
类。共享库中表示相同名称的类
即，有两个jar文件：




在alfresco-share-4.2.2.5.jar#uzip/org/alfresco/web/evaluator
中，我找到了我所需要的一切
此解决方案现在可以工作：
package com.firm.alfresco.alf221.evaluators;

// was import org.alfresco.web.ui.common.component.evaluator.BaseEvaluator;
import org.alfresco.web.evaluator.BaseEvaluator;
import org.json.simple.JSONObject;
import org.springframework.extensions.surf.RequestContext;
import org.springframework.extensions.surf.support.ThreadLocalRequestContext;
import org.springframework.extensions.webscripts.connector.User;


public class UsersCompareEvaluator extends BaseEvaluator  {

    @Override
    public boolean evaluate(JSONObject jSONObject) {
        RequestContext requestContext = ThreadLocalRequestContext.getRequestContext();
        User user = requestContext.getUser();

        System.out.println("CURRENT USER IS ... " + user.getName());

        return true;
    }
}

现在我可以在catalina.out中看到：
CURRENT USER IS ... admin

所有其他必要的信息都可以从JSONObject获得（当前用户也可以使用从BaseEvaluator
class继承的方法获得）
