```
public static <T, R> R doWithoutCommitAndFetchResult(Class<T> mapperClazz,
Function<T, R> func) {
// This line will open a new SqlSession if it does not exists
T mapper = SqlSessions.getMapper(mapperClazz);
// Use the sqlSession to perform SQL operations and DO NOT close session
return func.apply(mapper);
}
```
The method `doWithoutCommitAndFetchResult` and `doWithoutCommit` is designed
to be wrapped with `doMultipleWithCommit` and let `doMultipleWithCommit` close
the session automatically. However, in some places
like for example, `PolicyMetaService#listPoliciesForMetadataObject`, the
method is not called within `doMultipleWithCommit` and will lead to connections
leak.
If you have problem with this, please let me know, then try to fix it
another PR and rollback the lastes commit
