若存在日志slf4j-log4j12冲突的问题，解决如下：

日志冲突问题解决：
<dependency>
   <groupId>com.emc.ecs</groupId> 
   <artifactId>object-client</artifactId> 
   <version>3.1.3</version>
   <exclusions>
     <exclusion>

        <groupId>org.slf4j</groupId>
     </exclusion>
   </exclusions>
</dependency>

提供一个ECS的java工具类

Java

生命周期

配置过期策略，支持增删改查，注意，若当前Bucket策略空，直接删除会报错。.Net版本
查询

private LifecycleConfiguration GetEcsRules() {
    // Retrieve current configuration
    GetLifecycleConfigurationRequest getRequest  = new GetLifecycleConfigurationRequest {
            BucketName = _bucketName  };
    var response = _s3Client.GetLifecycleConfiguration(getRequest);
    return (response != null && response.Configuration != null) ? response.Configuration : null;
}

删除

private void DeleteEcsRules() {
    // Delete current configuration
    DeleteLifecycleConfigurationRequest deleteRequest  = new DeleteLifecycleConfigurationRequest {
            BucketName = _bucketName  };
    _s3Client.DeleteLifecycleConfiguration(deleteRequest);
}

更新

private void UpdateEcsRules(LifecycleConfiguration lcConfig_New = null) {
    LifecycleRuleExpiration lcRuleExpiration =  new LifecycleRuleExpiration() {
            Days = _expireDay, };

    LifecycleRule lcRule_1 = new LifecycleRule() {
        Expiration = lcRuleExpiration,
        Prefix = DateTime.Now.AddDays(-2).ToString(_prefix_format),
        Status = LifecycleRuleStatus.Enabled,
    };

    LifecycleConfiguration lcConfig = new LifecycleConfiguration();
    lcConfig.Rules.Add(lcRule_1);

    PutLifecycleConfigurationRequest request  = new PutLifecycleConfigurationRequest() {
            BucketName = _bucketName,  Configuration = lcConfig,
    };
    _s3Client.PutLifecycleConfiguration(request);
}
