# 标记资源
<a name="sdk-tagresource"></a>

以下示例演示了如何使用 [TagResource](https://docs.amazonaws.cn/acm/latest/APIReference/API_TagResource.html) 函数。此 API 支持除资源类型之外的所有 ACM `certificate` 资源类型。要获取证书资源，请使用[AddTagsToCertificate](https://docs.amazonaws.cn/acm/latest/APIReference/API_AddTagsToCertificate.html)。

```
package com.amazonaws.samples;

import com.amazonaws.services.certificatemanager.AWSCertificateManagerClientBuilder;
import com.amazonaws.services.certificatemanager.AWSCertificateManager;
import com.amazonaws.services.certificatemanager.model.TagResourceRequest;
import com.amazonaws.services.certificatemanager.model.Tag;

import java.util.ArrayList;

public class AWSCertificateManagerSample {

    public static void main(String[] args) {

        AWSCertificateManager client = AWSCertificateManagerClientBuilder.defaultClient();

        // Specify the tags to add.
        Tag tag1 = new Tag()
            .withKey("Environment")
            .withValue("Production");

        ArrayList<Tag> tags = new ArrayList<>();
        tags.add(tag1);

        // Create a request object.
        TagResourceRequest req = new TagResourceRequest()
            .withResourceArn("arn:aws:acm:us-east-1:123456789012:acme-endpoint/ep-abc123")
            .withTags(tags);

        // Tag the resource.
        client.tagResource(req);
    }
}
```
