生命周期规则可针对前缀或对象标签生效，您也可以同时指定两者作为生命周期规则生效的条件。

说明 Tag条件中，标签的Key和Value必须同时匹配。同一个规则中，若同时配置了前缀和多个对象标签，则对象需满足前缀，且同时匹配规则中所有对象标签，才视为适用于该规则。

生命周期规则中添加标签匹配规则

以下代码用于生命周期规则中添加标签匹配规则： 
// Endpoint以杭州为例，其它Region请按实际情况填写。
String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// 阿里云主账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建RAM账号。
String accessKeyId = "<yourAccessKeyId>";
String accessKeySecret = "<yourAccessKeySecret>";
String bucketName = "<yourBucketName>";

// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

// 创建SetBucketLifecycleRequest
SetBucketLifecycleRequest request = new SetBucketLifecycleRequest(bucketName);

// 设置规则ID、文件前缀与标签。
String ruleId0 = "rule0";
String matchPrefix0 = "A0/";
Map<String, String> matchTags0 = new HashMap<String, String>();
matchTags0.put("key0", "value0");


String ruleId1 = "rule1";
String matchPrefix1 = "A1/";
Map<String, String> matchTags1 = new HashMap<String, String>();
matchTags1.put("key1", "value1");


String ruleId2 = "rule2";
String matchPrefix2 = "A2/";

String ruleId3 = "rule3";
String matchPrefix3 = "A3/";

// 距最后修改时间3天后过期。
LifecycleRule rule = new LifecycleRule(ruleId0, matchPrefix0, RuleStatus.Enabled, 3);
rule.setTags(matchTags0)
request.AddLifecycleRule(rule);

// 指定日期之前创建的文件过期。
rule = new LifecycleRule(ruleId1, matchPrefix1, RuleStatus.Enabled);
rule.setCreatedBeforeDate(DateUtil.parseIso8601Date("2022-10-12T00:00:00.000Z"));
rule.setTags(matchTags1)
request.AddLifecycleRule(rule);

// 分片3天后过期。
rule = new LifecycleRule(ruleId2, matchPrefix2, RuleStatus.Enabled);
LifecycleRule.AbortMultipartUpload abortMultipartUpload = new LifecycleRule.AbortMultipartUpload();
abortMultipartUpload.setExpirationDays(3);
rule.setAbortMultipartUpload(abortMultipartUpload);
request.AddLifecycleRule(rule);

// 指定日期之前的分片过期。
rule = new LifecycleRule(ruleId3, matchPrefix3, RuleStatus.Enabled);
abortMultipartUpload = new LifecycleRule.AbortMultipartUpload();
abortMultipartUpload.setCreatedBeforeDate(DateUtil.parseIso8601Date("2022-10-12T00:00:00.000Z"));
rule.setAbortMultipartUpload(abortMultipartUpload);
request.AddLifecycleRule(rule);

ossClient.setBucketLifecycle(request);

// 关闭OSSClient。
ossClient.shutdown();

查看生命周期规则中匹配的标签信息

以下代码用于查看生命周期规则中匹配的标签信息： 
// Endpoint以杭州为例，其它Region请按实际情况填写。
String endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// 阿里云主账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建RAM账号。
String accessKeyId = "<yourAccessKeyId>";
String accessKeySecret = "<yourAccessKeySecret>";
String bucketName = "<yourBucketName>";

// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

// 获取生命周期规则。
List<LifecycleRule> rules = ossClient.getBucketLifecycle(bucketName);

// 查看生命周期规则。
for (LifecycleRule rule1 : rules) {
    // 查看规则id。
    System.out.println("rule id: " + rule1.getId());

    // 查看规则前缀。
    System.out.println("rule prefix: " + rule1.getPrefix());

    // 查看规则标签。
    if (rule1.hasTags()) {
     System.out.println("rule tagging: "+ rule1.getTags().toString());
    }

    //查看过期天数规则。
    if (rule1.hasExpirationDays()) {
     System.out.println("rule expiration days: " + rule1.getExpirationDays());
    }

    //查看过期日期规则。
    if (rule1.hasCreatedBeforeDate()) {
      System.out.println("rule expiration create before days: " + rule1.getCreatedBeforeDate());
    }

    //查看过期分片规则。
    if(rule1.hasAbortMultipartUpload()) {
        if(rule1.getAbortMultipartUpload().hasExpirationDays()) {
          System.out.println("rule abort uppart days: " + rule1.getAbortMultipartUpload().getExpirationDays());
        }

        if (rule1.getAbortMultipartUpload().hasCreatedBeforeDate()) {
          System.out.println("rule abort uppart create before date: " + rule1.getAbortMultipartUpload().getCreatedBeforeDate());
        }
    }
}

// 关闭OSSClient。
ossClient.shutdown();
