Pull request overview
This pull request implements a JSON export service layer for intelligence products, enabling programmatic access to risk assessments, coalition alignment matrices, and temporal trend analyses. The implementation introduces a new service interface and implementation, along with supporting DTOs, to serialize data from existing DAO layer for CDN-ready static file generation.
Key Changes
- New service layer (
IntelligenceExportServiceinterface and implementation) with Jackson-based JSON serialization - Three DTO classes for structured JSON export:
RiskAssessmentExportDTO,CoalitionAlignmentExportDTO, andTemporalTrendsExportDTO - Common
ExportMetadataDTO for consistent metadata across exports - Unit tests using Mockito for the three main export methods
- Documentation updates in json-export-specs README

The fully-qualified class name is unnecessary here since RuleViolation is already imported at line 37 and used without FQCN on line 79. This should simply be:

The test references a constructor ViewRiksdagenCoalitionAlignmentMatrixEmbeddedId(String, String) that doesn't exist in the model class. The class only has a no-argument constructor. The test should use the no-arg constructor followed by setter calls:
final ViewRiksdagenCoalitionAlignmentMatrixEmbeddedId embeddedId =
new ViewRiksdagenCoalitionAlignmentMatrixEmbeddedId();
embeddedId.setParty1("S");
embeddedId.setParty2("V");| new ViewRiksdagenCoalitionAlignmentMatrixEmbeddedId("S", "V"); | |

The writeJsonToFile method is not covered by unit tests. Add a test case to verify file creation, directory creation, and content writing behavior. Consider testing both scenarios: when the directory exists and when it needs to be created.

The class is declared as public class which breaks the codebase convention. All other service implementations in this package use final class with package-private visibility (no public modifier). This should be:

The writeJsonToFile method is vulnerable to path traversal attacks. An attacker could provide a malicious fileName containing path traversal sequences (e.g., ../../etc/passwd) to write files outside the intended directory. Validate and sanitize the fileName parameter to ensure it doesn't contain directory separators or path traversal sequences:
// Validate fileName doesn't contain path separators
if (fileName.contains("/") || fileName.contains("\\") || fileName.contains("..")) {
throw new IllegalArgumentException("Invalid file name: must not contain path separators or traversal sequences");

Fixed in 5fc4262. Added validation to reject file names containing /, \, or .. to prevent path traversal attacks. Throws IllegalArgumentException with descriptive message.

The use of mkdirs() without checking the return value can lead to silent failures. If directory creation fails (e.g., due to permissions), the subsequent Files.write() will fail. Check the return value and throw an appropriate exception:
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Failed to create directory: " + outputDirectory);

These DTOs are specifically designed for Jackson JSON serialization where the service implementation populates the lists via dto.getAlignments().add().

The ObjectMapper is configured to disable WRITE_DATES_AS_TIMESTAMPS, but Jackson also needs a date format configuration to properly serialize dates as ISO 8601 strings. Without an explicit date format, dates may not serialize consistently.
Consider adding:
this.objectMapper.setDateFormat(new StdDateFormat().withColonInTimeZone(true));This ensures dates are serialized as ISO 8601 strings (e.g., "2024-12-08T11:12:00Z") as described in the PR description.

The security validation for path traversal is incomplete. The check fileName.contains("..") will reject legitimate file names like "risk-2024..2025.json" that contain ".." as part of the content, not just as a traversal sequence.
A more robust check should validate that the resolved path stays within the target directory:
final Path targetDir = Paths.get(outputDirectory).toAbsolutePath().normalize();
final Path resolvedPath = targetDir.resolve(fileName).normalize();
if (!resolvedPath.startsWith(targetDir)) {
throw new IllegalArgumentException("Invalid file name: path traversal detected");
}This approach properly prevents path traversal while allowing legitimate file names.

Fixed in ac4dbfe. Replaced simple string contains check with robust path validation using Path.normalize() and startsWith() to properly detect path traversal while allowing legitimate file names. The implementation now validates that the resolved path stays within the target directory.

[nitpick] The test description "Test various path traversal attempts" includes a case that tests legitimate path usage ("path/to/file.json") which should arguably be allowed for creating files in subdirectories. However, this conflicts with the current implementation which rejects all path separators.
If the intention is to only allow flat file names in the specified directory (no subdirectories), this test is correct but the error message should clarify that subdirectories are not supported. If subdirectories should be supported, both the implementation and test need adjustment.
Consider clarifying the intended behavior in the JavaDoc for writeJsonToFile().
There was a problem hiding this comment.
Fixed in ac4dbfe. Updated JavaDoc for writeJsonToFile() to clarify that subdirectories are not supported and only flat file names are accepted. The error message now specifies "subdirectories not supported" for path separator rejections, making the intended behavior clear.
