java 通过 microsoft graph 调用outlook(三)

这次会添加一个Reply接口，

并且使用6.10.0版本

直接上代码

一， POM

        <!--    office 365    -->
        <dependency>
            <groupId>com.microsoft.graph</groupId>
            <artifactId>microsoft-graph</artifactId>
            <version>6.10.0</version>
            <!--x-release-please-end-->
        </dependency>
        <dependency>
            <groupId>com.azure</groupId>
            <artifactId>azure-identity</artifactId>
            <version>1.11.0</version>
        </dependency>
        <!--    office 365    -->

二，Service / impl

主要讲一下Reply方法，Reply本质是添加评论，我们所有回复邮件，可以看到上下文时，实际都是添加了评论而已。（对比了outlook是一样的）

而Reply添加的附件，只有最后一份才会显示附件。

其他的附件，都只能在各自发送的邮件中找到，而Reply的连续回复中，只会有最后的附件。

MessageVo

import lombok.Data;
 
import java.util.ArrayList;
import java.util.List;
 
@Data
public class MessageVo {
    private String messageId;
    private List<String> recipients;
    private String subject;
    private String body;
    private List<FileAttachment> attachments=new ArrayList<>();
}
