要将Adobe AEM（Adobe Experience Manager）组件从HTL转换为HTML，可以使用以下代码示例：

1. 创建一个HTL组件（例如，sample.htl）：

    
${sample.title}
    
${sample.description}

2. 创建一个Java类（例如，Sample.java），用于将HTL组件转换为HTML：

// Sample.java
import org.apache.sling.api.resource.Resource;
import org.apache.sling.api.scripting.SlingScriptHelper;
import org.apache.sling.api.scripting.SlingBindings;
import org.apache.sling.scripting.sightly.pojo.Use;

public class Sample implements Use {
    private String title;
    private String description;

    @Override
    public void init(Bindings bindings) {
        SlingBindings slingBindings = (SlingBindings) bindings;
        SlingScriptHelper sling = slingBindings.getSling();
        Resource resource = slingBindings.getResourceResolver().getResource(slingBindings.get("resource").toString());

        // 获取组件属性
        title = resource.getValueMap().get("title", String.class);
        description = resource.getValueMap().get("description", String.class);
    }

    public String getTitle() {
        return title;
    }

    public String getDescription() {
        return description;
    }
}

3. 创建一个用于将HTL组件呈现为HTML的Java Servlet：

// SampleServlet.java
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.sling.api.resource.ResourceResolver;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.api.scripting.SlingScriptHelper;
import org.apache.sling.scripting.sightly.pojo.Use;

public class SampleServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        ResourceResolverFactory resourceResolverFactory = // 获取ResourceResolverFactory实例
        ResourceResolver resourceResolver = // 使用ResourceResolverFactory获取ResourceResolver实例
        SlingScriptHelper sling = // 获取SlingScriptHelper实例
        
        // 获取HTL组件的Resource
        Resource resource = resourceResolver.getResource("/apps/sample/sample.htl");

        // 使用HTL组件和Java类将HTL转换为HTML
        Use sample = sling.getService(Use.class);
        sample.init(sling.getBindings());
        String html = sling.include(resource.getPath(), "sample.html", true);

        // 将HTML响应发送回客户端
        response.setContentType("text/html");
        response.getWriter().write(html);
    }
}

在上述代码示例中，HTL组件（sample.htl）定义了一个包含标题和描述的简单div元素。Java类（Sample.java）用于获取组件的属性，并通过getter方法将它们提供给HTL组件。Java Servlet（SampleServlet.java）使用HTL组件和Java类将HTL转换为HTML，并将HTML响应发送回客户端。

请注意，在实际应用中，可能需要自定义和调整代码以适应特定的开发需求和AEM环境。
