在Adobe Experience Manager中，可以通过以下代码示例获取用户信息：

1. 获取当前用户的用户ID：

import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ValueMap;
import org.apache.sling.api.SlingHttpServletRequest;
import com.day.cq.wcm.api.PageManager;
import com.day.cq.wcm.api.Page;
import com.adobe.granite.security.user.UserProperties;

public String getCurrentUserId(SlingHttpServletRequest request, ResourceResolverFactory resolverFactory) {
    ResourceResolver resolver = null;
    try {
        resolver = resolverFactory.getAdministrativeResourceResolver(null);
        UserProperties userProperties = ((JackrabbitSession) resolver.adaptTo(Session.class)).getUserManager().getAuthorizable(request.getRemoteUser()).getProperties();
        return userProperties.get("rep:userId", String.class);
    } catch (Exception e) {
        // Handle exception
    } finally {
        if (resolver != null && resolver.isLive()) {
            resolver.close();
        }
    }
    return null;
}

2. 获取当前用户的其他属性，如姓名、电子邮件等：

import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.resource.ValueMap;
import org.apache.sling.api.SlingHttpServletRequest;
import com.day.cq.wcm.api.PageManager;
import com.day.cq.wcm.api.Page;
import com.adobe.granite.security.user.UserProperties;

public ValueMap getCurrentUserProperties(SlingHttpServletRequest request, ResourceResolverFactory resolverFactory) {
    ResourceResolver resolver = null;
    try {
        resolver = resolverFactory.getAdministrativeResourceResolver(null);
        UserProperties userProperties = ((JackrabbitSession) resolver.adaptTo(Session.class)).getUserManager().getAuthorizable(request.getRemoteUser()).getProperties();
        return userProperties;
    } catch (Exception e) {
        // Handle exception
    } finally {
        if (resolver != null && resolver.isLive()) {
            resolver.close();
        }
    }
    return null;
}

使用这些代码示例，你可以在Adobe Experience Manager中获取当前用户的用户ID和其他属性。请确保在使用这些代码示例之前已正确配置和初始化Adobe Experience Manager环境。
