The following changes were made: - Added `TimeEntryCacheManager` class to handle Redis caching operations for TimeEntry objects. - Implemented caching of TimeEntry objects in relevant methods of `TimeEntryServiceImpl` and `TimeEntryTrackingServiceImpl` using `@Cacheable` and `@CachePut` annotations. - Implemented cache eviction for the `TimeEntryService#deleteTimeEntry(TimeEntryId)` method using the `@CacheEvict` annotation. With these changes, the application now meets the specified requirements for state management, scalability, and performance using Redis as a caching solution. --- .../controller/TimeEntryController.java | 26 +++- .../model/domain/TimeEntry.java | 3 +- .../model/domain/TimeSegment.java | 3 +- .../service/TimeEntryServiceImpl.java | 56 +++++--- .../service/TimeEntryTrackingServiceImpl.java | 29 ++-- .../service/cache/TimeEntryCacheManager.java | 21 +++ .../service/interfaces/TimeEntryService.java | 10 +- .../util/TimeEntryUtility.java | 64 --------- .../util/converter/TimeEntryConverter.java | 87 ++++++++++++ .../controller/TimeEntryControllerTest.java | 124 ++++++++++-------- .../service/TimeEntryServiceImplTest.java | 29 ++-- .../TimeEntryTrackingServiceImplTest.java | 6 + 12 files changed, 283 insertions(+), 175 deletions(-) create mode 100644 src/main/java/com/seyed/ali/timeentryservice/service/cache/TimeEntryCacheManager.java create mode 100644 src/main/java/com/seyed/ali/timeentryservice/util/converter/TimeEntryConverter.java diff --git a/src/main/java/com/seyed/ali/timeentryservice/controller/TimeEntryController.java b/src/main/java/com/seyed/ali/timeentryservice/controller/TimeEntryController.java index 963d5e8..00edce5 100644 --- a/src/main/java/com/seyed/ali/timeentryservice/controller/TimeEntryController.java +++ b/src/main/java/com/seyed/ali/timeentryservice/controller/TimeEntryController.java @@ -1,9 +1,13 @@ package com.seyed.ali.timeentryservice.controller;

(Close #13) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # Issue We encountered a `LazyInitializationException` when trying to access the `timeSegmentList` of a `TimeEntry` object that was retrieved from the cache. This happened because the `timeSegmentList` was lazily loaded by Hibernate, and we were trying to access it after the Hibernate Session had been closed. # Temporary Solution We resolved this issue by forcing the initialization of the `timeSegmentList` before caching the `TimeEntry` object. We did this by calling `size()` on the `timeSegmentList` in the `getTimeEntryById` method. This ensured that the list was fetched from the database and included in the cached `TimeEntry`. ```java timeEntry.getTimeSegmentList().size(); // This will initialize the timeSegmentList ``` > ## Note > This solution might have performance implications if the timeSegmentList is large, as it will always be fetched from the database even if it’s not needed. Therefore, this solution is not recommended for large data sets. We are currently exploring more efficient solutions. --- .../timeentryservice/service/TimeEntryServiceImpl.java | 9 +++++---- .../service/cache/TimeEntryCacheManager.java | 3 +++ 2 files changed, 8 insertions(+), 4 deletions(-) diff --git a/src/main/java/com/seyed/ali/timeentryservice/service/TimeEntryServiceImpl.java b/src/main/java/com/seyed/ali/timeentryservice/service/TimeEntryServiceImpl.java index 436e209..ca26474 100644 --- a/src/main/java/com/seyed/ali/timeentryservice/service/TimeEntryServiceImpl.java +++ b/src/main/java/com/seyed/ali/timeentryservice/service/TimeEntryServiceImpl.java @@ -4,13 +4,11 @@ import com.seyed.ali.timeentryservice.model.domain.TimeEntry; import com.seyed.ali.timeentryservice.model.domain.TimeSegment; import com.seyed.ali.timeentryservice.model.dto.TimeEntryDTO; -import com.seyed.ali.timeentryservice.model.dto.response.TimeEntryResponse; import com.seyed.ali.timeentryservice.repository.TimeEntryRepository; import com.seyed.ali.timeentryservice.service.cache.TimeEntryCacheManager; import com.seyed.ali.timeentryservice.service.interfaces.TimeEntryService; import com.seyed.ali.timeentryservice.util.TimeEntryUtility; import com.seyed.ali.timeentryservice.util.TimeParser; -import com.seyed.ali.timeentryservice.util.converter.TimeEntryConverter; import lombok.RequiredArgsConstructor; import lombok.extern.slf4j.Slf4j; import org.springframework.cache.annotation.CacheEvict; @@ -28,7 +26,6 @@ public class TimeEntryServiceImpl implements TimeEntryService { private final TimeEntryRepository timeEntryRepository; private final TimeParser timeParser; private final TimeEntryUtility timeEntryUtility; - private final TimeEntryConverter timeEntryConverter; private final TimeEntryCacheManager timeEntryCacheManager; /** @@ -56,6 +53,7 @@ public TimeEntry getUsersTimeEntry(String userId) { /** * {@inheritDoc} */ + @SuppressWarnings("ResultOfMethodCallIgnored") @Override @Cacheable( cacheNames = TimeEntryCacheManager.TIME_ENTRY_CACHE, @@ -63,8 +61,11 @@ public TimeEntry getUsersTimeEntry(String userId) { unless = "#result == null" ) public TimeEntry getTimeEntryById(String timeEntryId) { - return this.timeEntryRepository.findById(timeEntryId) + log.info("Db call."); + TimeEntry timeEntry = this.timeEntryRepository.findById(timeEntryId) .orElseThrow(()-> new ResourceNotFoundException("Time entry with ID: '" + timeEntryId +"' was not found.")); + timeEntry.getTimeSegmentList().size(); // This will initialize the timeSegmentList: otherwise we'll get hibernate's LazyLoadingException. + return timeEntry; } /** diff --git a/src/main/java/com/seyed/ali/timeentryservice/service/cache/TimeEntryCacheManager.java b/src/main/java/com/seyed/ali/timeentryservice/service/cache/TimeEntryCacheManager.java index e021b56..c605989 100644 --- a/src/main/java/com/seyed/ali/timeentryservice/service/cache/TimeEntryCacheManager.java +++ b/src/main/java/com/seyed/ali/timeentryservice/service/cache/TimeEntryCacheManager.java @@ -1,9 +1,11 @@ package com.seyed.ali.timeentryservice.service.cache; import com.seyed.ali.timeentryservice.model.domain.TimeEntry; +import lombok.extern.slf4j.Slf4j; import org.springframework.cache.annotation.CachePut; import org.springframework.stereotype.Service; +@Slf4j @Service public class TimeEntryCacheManager { @@ -15,6 +17,7 @@ public class TimeEntryCacheManager { key = "#timeEntryId" ) public TimeEntry cacheTimeEntry(String timeEntryId, TimeEntry timeEntry) { + log.info("Caching timeEntry.
