Confluence api 写一段上传附件的java代码

好的，以下是一个简单的上传附件的java代码示例：

import com.atlassian.confluence.api.ConfluenceApi;
import com.atlassian.confluence.api.model.content.Content;
import com.atlassian.confluence.api.model.content.ContentType;
import com.atlassian.confluence.api.model.content.ContentBody;

public class ConfluenceAttachmentUploader {

    private final ConfluenceApi confluence;
    private final String pageTitle;
    private final String pageContent;
    private final String attachmentFilePath;

    public ConfluenceAttachmentUploader(ConfluenceApi confluence, String pageTitle, String pageContent, String attachmentFilePath) {
        this.confluence = confluence;
        this.pageTitle = pageTitle;
        this.pageContent = pageContent;
        this.attachmentFilePath = attachmentFilePath;
    }

    public void uploadAttachment() throws IOException, PermissionException {
        // Create page content
        ContentBody contentBody = ContentBody.builder()
                .value(pageContent)
                .representation(ContentBody.Representation.STORAGE)
                .build();

        ContentCreationRequest contentCreationRequest = ContentCreationRequest.builder()
                .space(confluence.getContentService().find().byTitle(ContentType.SPACE, "My Space")).get().getId())
                .type(ContentType.PAGE)
                .title(pageTitle)
                .body(contentBody)
                .build();

        Content page = confluence.getContentService().create(contentCreationRequest).claim();

        // Upload attachment
        InputStream inputStream = new FileInputStream(new File(attachmentFilePath));
        Upload upload = confluence.getContentService().upload(page.getId(), "attachment.png", inputStream).claim();

        // Update page with attachment
        ContentUpdateRequest contentUpdateRequest = ContentUpdateRequest.builder()
                .id(page.getId())
                .title(page.getTitle())
                .version(page.getVersion())
                .body(contentBody)
                .metadata(page.getMetadata())
                .attachments(Arrays.asList(upload))
                .build();

        confluence.getContentService().update(contentUpdateRequest).claim();
    }
}

请注意，您需要替换以下变量：

- `confluence`: 您的ConfluenceApi对象。
- `pageTitle`: 您要创建的页面的标题。
- `pageContent`: 您要创建的页面的内容。
- `attachmentFilePath`：您要上传的附件的文件路径。

这个示例假设您已经有一个名为"My Space"的空间，您需要将其替换为您实际的空间名称。同时，您还需要进行适当的错误处理和认证，以确保您的代码可以正常运行。
