1. 确认网络连接是否正常，以及URL或API是否正确。
2. 检查AEM Venia Store配置文件中的端口号和文件路径是否正确。
3. 验证相关代码是否正确，尤其是使用的API是否正确。 以下是一个可能的示例代码（使用Sling API获取商品数据）：

import org.apache.sling.api.SlingHttpServletRequest; import org.apache.sling.api.SlingHttpServletResponse; import org.apache.sling.api.resource.Resource; import org.apache.sling.api.resource.ResourceResolver; import org.apache.sling.api.resource.ResourceNotFoundException; import org.apache.sling.api.resource.ResourceResolverFactory; import org.osgi.framework.Constants; import org.osgi.service.component.annotations.Component; import org.osgi.service.component.annotations.Reference; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import com.adobe.cq.commerce.api.Product; import com.adobe.cq.commerce.api.ProductData; import com.adobe.cq.commerce.api.ProductFilter; import com.adobe.cq.commerce.common.AbstractJcrProduct; import com.adobe.cq.commerce.common.AbstractJcrProductData; import com.adobe.cq.commerce.common.AbstractProductData; import com.adobe.cq.commerce.common.PriceImpl; import javax.jcr.Node; import javax.jcr.PropertyIterator; import javax.jcr.RepositoryException; import javax.jcr.Value; import java.math.BigDecimal; import java.util.ArrayList; import java.util.Collection; import java.util.Iterator; import java.util.List; import java.util.Map;
