apollo-client/src/main/java/com/ctrip/framework/apollo/util/date/DateUtil.java (1)
22-26: Enhance class-level Javadoc commentWhile the author and date information is provided, it would be beneficial to include a brief description of the class's purpose and functionality. This helps other developers understand the utility's role at a glance.
Consider adding a description like this:
/** * Utility class for date and time formatting operations. * Provides standardized formatting for LocalDateTime objects. * * @author Rawven * @date 2024/10/19 */ public class DateUtil { // ... existing code ... }apollo-client/src/main/java/com/ctrip/framework/apollo/monitor/internal/listener/impl/DefaultApolloClientBootstrapArgsApi.java (2)
94-97: LGTM with suggestion: Add null check in putAttachmentValue method.The
putAttachmentValuemethod improves code maintainability and ensures consistency betweenbootstrapArgsandbootstrapArgsString. However, consider adding a null check to prevent potential NullPointerExceptions.Consider modifying the method as follows:
private void putAttachmentValue(String argName, Object value) { bootstrapArgs.put(argName, value); - bootstrapArgsString.put(argName, value.toString()); + bootstrapArgsString.put(argName, value != null ? value.toString() : "null"); }
Line range hint
1-114: Overall improvements with some objectives unaddressed.The changes to
DefaultApolloClientBootstrapArgsApiimprove code consistency and provide additional useful information (initialization timestamp). However, the modifications don't directly address the issues mentioned in the PR objectives:
- Redundant logging when MetricsExporter is not enabled.
- Default values for monitoring parameters to prevent null pointer exceptions.
Consider addressing these objectives in this or a follow-up PR to fully meet the goals outlined in issue #85.
apollo-client/src/main/java/com/ctrip/framework/apollo/internals/ConfigMonitorInitializer.java (1)
106-113: LGTM: Early return for disabled metrics exporterThe addition of an early return when the metrics exporter is not enabled effectively addresses the issue of redundant logging mentioned in the PR objectives. This change enhances the Client-Monitor user experience by preventing unnecessary initialization and logging.
A minor suggestion for improvement:
Consider extracting the condition into a separate method for better readability and potential reuse. For example:
private boolean isMetricsExporterDisabled() { return StringUtils.isEmpty(m_configUtil.getMonitorExternalType()) || "NONE".equals(m_configUtil.getMonitorExternalType()); } private static void initializeMetricsExporter() { if (isMetricsExporterDisabled()) { return; } // ... rest of the method }This extraction would make the main method more concise and the condition more self-explanatory.
apollo-client/src/main/java/com/ctrip/framework/apollo/monitor/internal/tracer/ApolloClientMonitorMessageProducer.java (1)
129-129: Improved date-time formatting.The change from
LocalDate.now().toString()toDateUtil.formatLocalDateTime(LocalDateTime.now())is a good improvement. It provides more precise and standardized date-time formatting, which aligns with the objective of maintaining consistent date handling across the application.Consider caching the current date-time value if it's used multiple times within the method to avoid repeated calls to
LocalDateTime.now().+ LocalDateTime now = LocalDateTime.now(); - .putAttachment(META_FRESH, DateUtil.formatLocalDateTime(LocalDateTime.now()))); + .putAttachment(META_FRESH, DateUtil.formatLocalDateTime(now)));apollo-client/src/main/java/com/ctrip/framework/apollo/monitor/internal/listener/impl/DefaultApolloClientNamespaceApi.java (1)
Line range hint
1-205: Summary: Improved date formatting enhances consistency.The changes in this file are minimal but impactful. By standardizing the date formatting using
DateUtil.formatLocalDateTime(), the code now provides a more consistent and potentially more readable output for namespace metrics. This aligns well with the PR objective of enhancing the user experience.These changes:
- Improve code maintainability by centralizing date formatting logic.
- Potentially enhance readability of the output for users and integrating systems.
Consider applying similar date formatting standardization across the entire project for consistency. This could be a good opportunity to create or update coding guidelines regarding date and time handling in the Apollo Client project.

1-32: Overall assessment: Good implementation with room for minor improvementsThe
DateUtilclass is a well-structured utility for date formatting, which aligns with the PR objectives of enhancing user experience and maintaining consistent date formatting. The implementation is generally sound, but there are a few areas for improvement:
- Enhance the class-level Javadoc with a description of the class's purpose.
- Consider making the
MEDIUM_FORMATTERfieldfinaland possiblyprivatefor better encapsulation.- Add method-level Javadoc and null handling to the
formatLocalDateTimemethod.These suggestions will improve the code's documentation, robustness, and maintainability. Once these minor adjustments are made, the class will be in excellent shape.

43-43: Good improvement to logger initialization!The change to use
PrometheusApolloClientMetricsExporter.classinstead ofDefaultApolloClientNamespaceApi.classfor logger initialization follows best practices. This ensures that log messages are correctly attributed to their source class, improving traceability and debugging capabilities.apollo-client/src/main/java/com/ctrip/framework/apollo/monitor/internal/listener/impl/DefaultApolloClientBootstrapArgsApi.java (4)
31-31: LGTM! Appropriate imports added for date handling.The new imports support the META_FRESH functionality and follow the project's conventions.
Also applies to: 34-34
52-79: LGTM! Improved initialization with consistent method usage and timestamp tracking.The changes enhance the code by:
- Using a consistent method for all value assignments
- Adding META_FRESH timestamp for tracking initialization time
88-88: LGTM! Consistent usage of putAttachmentValue method.The change ensures atomic updates to both maps and maintains consistency with the rest of the code.
66-67: Verify logging improvement for disabled MetricsExporter.The PR objectives mention reducing unnecessary logging when MetricsExporter is not enabled. While these lines set the monitor configuration, we should verify if the logging improvement is implemented elsewhere.
✅ Verification successful
Based on the gathered information, I can now generate the final response:
Logging improvement is properly implemented for disabled MetricsExporter
The codebase shows proper handling of disabled monitoring:
- When monitoring is disabled (
isClientMonitorEnabled() == false), aNullApolloClientMetricsExporteris used which only logs a single warning message- The monitoring state is checked early in the event publishing flow to prevent unnecessary processing
- The configuration is properly propagated through
ConfigUtiland respected throughout the monitoring system🏁 Scripts executed

1-85: Consider adding test cases for the issues mentioned in #85.The current test suite doesn't cover the specific scenarios mentioned in issue #85:
- MetricsExporter disabled state and logging behavior
- Default values for monitoring parameters to prevent NPEs
Consider adding these test cases:
@Test public void testMetricsExporterDisabled() { // Given when(monitorContext.getMetricsExporter()).thenReturn(null); DefaultConfigMonitor configMonitor = new DefaultConfigMonitor(); // When/Then assertNull(configMonitor.getExporterData()); } @Test public void testBootstrapArgsDefaultValues() { // Given DefaultConfigMonitor configMonitor = new DefaultConfigMonitor(); // When ApolloClientBootstrapArgsMonitorApi api = configMonitor.getBootstrapArgsMonitorApi(); // Then assertNotNull(api.getMetaFreshTime()); // Should return default value instead of null }

42-42: LGTM! The method rename improves clarity.The rename from
getRunningParamsMonitorApitogetBootstrapArgsMonitorApibetter reflects the actual functionality of retrieving bootstrap arguments.Let's verify all implementations have been updated:
✅ Verification successful
Let me try a different search strategy to verify the implementations.
Method rename has been properly implemented across the codebase
The verification shows that:
- The old method name
getRunningParamsMonitorApihas no remaining references in the codebase- The new method
getBootstrapArgsMonitorApiis properly implemented inDefaultConfigMonitor- All related test cases have been updated to use the new method name
- The change is consistently reflected across all relevant files
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check for any missed implementations or references to the old method name # Search for any remaining references to the old method name echo "Checking for any remaining references to getRunningParamsMonitorApi..." rg "getRunningParamsMonitorApi" # Search for implementations of ConfigMonitor to verify updates echo "Checking ConfigMonitor implementations..." ast-grep --pattern 'class $_ implements ConfigMonitor { $$$ }'Length of output: 342
Script:
#!/bin/bash # Search for implementations using different patterns # Find all files that might contain ConfigMonitor implementations echo "Files containing ConfigMonitor reference:" rg -l "ConfigMonitor" # Search for the new method name to verify implementations echo -e "\nChecking implementations of new method name:" rg "getBootstrapArgsMonitorApi" -A 2 # Search for files containing ApolloClientBootstrapArgsMonitorApi echo -e "\nFiles using ApolloClientBootstrapArgsMonitorApi:" rg -l "ApolloClientBootstrapArgsMonitorApi"Length of output: 3478
42-42: Update documentation and CHANGES log for this breaking change.This is a breaking API change that requires:
- Documentation updates for the new method name
- Entry in the CHANGES log
- Migration guide for users updating from previous versions
Let's check for documentation that needs updating:
