목록 <String>을 GroupMatcher로 변환하는 방법 <JobKey>

Question

목록을 GroupMatcher로 변환하는 방법?

내 코드가 이와 비슷합니다.

List<String> jobGroupNames = scheduler.getJobGroupNames(); 

은 지금은 여기에 jobGroupNames 목록입니다

for (GroupMatcher<JobKey> jobGroup : jobGroupNames) { 
} 

을 확인하려면, 그래서 난이 오류 (GroupMatcher.groupEquals`처럼 GorupMatcher를 얻을 수

Type mismatch: cannot convert from element type String to GroupMatcher<JobKey>

jobGroupNames is a list of String, That's why you should iterate like below. 

// loop jobs by group 

List<String> jobGroupNames = scheduler.getJobGroupNames(); 

for (String groupName : jobGroupNames) { 

// And to get Job keys : 

    for (JobKey jobKey : scheduler.getJobKeys(GroupMatcher.jobGroupEquals(groupName))) { 
    } 
}
