1-100: Class violates Single Responsibility PrincipleThe ApiMgtDAO class has too many responsibilities handling different database operations for APIs, applications, subscriptions, policies etc. This makes the class hard to maintain and test.
Consider splitting into smaller focused DAO classes:
- APISubscriptionDAO - For subscription related operations
- APIPolicyDAO - For policy related operations
- APIBlockConditionDAO - For block condition operations
- APIApplicationDAO - For application operations
This will improve maintainability and testability of the code.

252-256: Error handling can be improvedThe error handling in catch block only logs the error and rethrows it without providing proper context.
catch (SQLException e) { - handleException("Error when executing the SQL query to read the access key for user : " + loginUserName + - "of tenant(id) : " + tenantId, e); + String msg = String.format("Failed to get access key for user %s in tenant %d. Cause: %s", + loginUserName, tenantId, e.getMessage()); + handleException(msg, e); }
Line range hint
1-50: Missing proper documentationThe class and many methods lack proper javadoc documentation explaining the purpose, parameters, return values and exceptions.
Add proper class and method level documentation:
/** * Data access layer for API Management related database operations. * Handles database operations for APIs, applications, subscriptions and policies. */ public class ApiMgtDAO { /** * Gets the access key for an API. * * @param userId User ID requesting the access key * @param applicationName Name of the application * @param identifier API identifier * @param keyType Type of key (PRODUCTION/SANDBOX) * @return Access key if found, null otherwise * @throws APIManagementException if database access fails */ public String getAccessKeyForAPI(String userId...) {
Line range hint
1-1500: Performance optimization needed for database operationsThe code makes multiple database calls in loops and doesn't use batch operations where possible.
Consider the following optimizations:
- Use batch operations for bulk inserts/updates
- Cache frequently accessed data
- Use connection pooling effectively
- Optimize queries to reduce number of database roundtrips
- Consider using database specific features for better performance
Example for batch operations:
PreparedStatement ps = conn.prepareStatement(sql); for(Item item : items) { ps.setString(1, item.getName()); ps.addBatch(); } ps.executeBatch();

1-1500: Verify SQL injection protection across all database operationsNeed to verify that all database operations are protected against SQL injection.
✅ Verification successful
SQL injection protection verified through proper PreparedStatement usage
The code is properly protected against SQL injection through consistent use of:
- PreparedStatement with parameter binding for all database operations
- Static SQL query constants
- Table name construction using only static constants
The only string concatenation found is for building table names using constants, which is safe since no user input is involved.

Critical security vulnerability in getAccessKeyForAPI method
The method uses string concatenation to build SQL query which is vulnerable to SQL injection attacks:
String query = String.format(
sqlQuery,
tenantAwareUserId,
tenantId,
APIUtil.replaceEmailDomainBack(identifier.getProviderId()),
identifier.getApiName(),
identifier.getVersion(),
applicationName,
keyType
);Use parameterized queries with PreparedStatement instead:
- String query = String.format(sqlQuery, ...);
- stmt = conn.createStatement();
- rs = stmt.executeQuery(query);
+ PreparedStatement ps = conn.prepareStatement(sqlQuery);
+ ps.setString(1, tenantAwareUserId);
+ ps.setInt(2, tenantId);
+ ps.setString(3, APIUtil.replaceEmailDomainBack(identifier.getProviderId()));
+ ps.setString(4, identifier.getApiName());
+ ps.setString(5, identifier.getVersion());
+ ps.setString(6, applicationName);
+ ps.setString(7, keyType);
+ rs = ps.executeQuery();| conn = APIMgtDBUtil.getConnection(); | ||
| stmt = conn.createStatement(); | ||
| rs = stmt.executeQuery(query); | ||
|
|
||
| while (rs.next()) { | ||
| accessKey = APIUtil.decryptToken(rs.getString(APIConstants.SUBSCRIPTION_FIELD_ACCESS_TOKEN)); | ||
| } | ||
| } catch (SQLException e) { | ||
| handleException("Error when executing the SQL query to read the access key for user : " + loginUserName + | ||
| "of tenant(id) : " + tenantId, e); | ||
| } catch (CryptoException e) { | ||
| handleException("Error when decrypting access key for user : " + loginUserName + "of tenant(id) : " + | ||
| tenantId, e); | ||
| } finally { | ||
| APIMgtDBUtil.closeAllConnections(stmt, conn, rs); | ||
| } |

Resource leak in database connection handling
The connection, statement and resultset are not properly closed in case of exceptions. This can lead to connection leaks.
Use try-with-resources to ensure proper resource cleanup:
- Connection conn = null;
- Statement stmt = null;
- ResultSet rs = null;
- try {
+ try (Connection conn = APIMgtDBUtil.getConnection();
+ PreparedStatement ps = conn.prepareStatement(sqlQuery);
+ ResultSet rs = ps.executeQuery()) {
// ... query execution code ...
- } finally {
- APIMgtDBUtil.closeAllConnections(stmt, conn, rs);
