嗨我想将图像保存到s3但我最近完成了，上传图像时控制台上显示了一些警告。如何解决它.. 如果图像存在，我想替换图像

 <bean id="projectDAO" class="com.startinpoint.proj.PMS.ProjectModule.ProjectDAOImpl">
    <property name="sessionFactory" ref="sessionFactory" />
 </bean>

 <!-- Phase -->
    <bean id="phaseBean" class="com.startinpoint.proj.PMS.PhaseModule.PhaseBean">
    <property name="phaseManager" ref="phaseManager" />
    </bean>
  <bean id="phaseManager" class="com.startinpoint.proj.PMS.PhaseModule.PhaseManager">
    <property name="phaseDAO" ref="phaseDAO" />
 </bean>

 <bean id="phaseDAO" class="com.startinpoint.proj.PMS.PhaseModule.PhaseDAOImpl">
    <property name="sessionFactory" ref="sessionFactory" />
 </bean>

 <!-- Task -->
   <bean id="taskBean" class="com.startinpoint.proj.PMS.TaskModule.TaskBean">
    <property name="taskManager" ref="taskManager" />
    </bean>
  <bean id="taskManager" class="com.startinpoint.proj.PMS.TaskModule.TaskManager">
    <property name="taskDAO" ref="taskDAO" />
 </bean>

 <bean id="taskDAO" class="com.startinpoint.proj.PMS.TaskModule.TaskDAOImpl">
    <property name="sessionFactory" ref="sessionFactory" />
 </bean>

您可以在Spring中使用本教程：依赖它。

private void saveImage(MultipartFile image) ImageUploadException {
    try {
        S3Bucket bucket = s3.getBucket("spittrImages");

        S3Object imageObject = new S3Object(image.getOriginalFilename());
        imageObject.setDataInputStream(image.getInputStream());

        imageObject.setContentLength(image.getSize());
        imageObject.setContentType(image.getContentType());

        AccessControlList acl = new AccessControlList();
        acl.setOwner(bucket.getOwner());
        acl.grantPermission(GroupGrantee.ALL_USERS, Permission.PERMISSION_READ);
        imageObject.setAcl(acl);

        s3.putObject(bucket, imageObject);
    } catch (Exception e) {
        throw new ImageUploadException("Unable to save image", e);
    }
}

将图像保存到aws s3，如果图像存在则替换图像
