Action Memo API Module

Create a Java Spring Boot module for managing action memos with the following components: 1. **Entity Class**: Define an entity `ActionMemo` representing the `PORTAL_ACTION_MEMOS` table with fields: `memoId`, `controlCode`, `claimId`, `healthFacility`, `physician`, `batchNumber`, `patientName`, `accountName`, `approvalNumber`, `availmentDate`, `memoType`, `action`, `dateCreated`, `createdBy`, `serviceType`, `status`, `providerUserId`, `createdTs`, `createdByField`, `updatedTs`, `updatedBy`, `message`, `type`, `providerCode`. Use JPA annotations: `@Entity`, `@Table`, primary key annotations like `@Id`, `@GeneratedValue`, column mappings with `@Column`, relationships with `@ManyToOne`, `@JoinColumn`, and specify `insertable=false, updatable=false` where necessary. Include Lombok annotations `@Data` and `@NoArgsConstructor`. 2. **Request Class**: Create a `PendingMemoRequest` with fields `page`, `size`, `search`, `status`, `memoType`, `fromDate`, and `toDate`. Add validation annotations such as `@NotNull`, `@NotBlank` and use `@Data` to generate boilerplate code. 3. **Response Class**: Define `PendingMemoResponse` containing: - A list of `MemoResponse` objects each having fields: `memoId`, `controlCode`, `healthFacility`, `physician`, `batchNumber`, `patientName`, `accountName`, `approvalNumber`, `availmentDate`, `submissionDate`, `memoType`, `status`, `documentId`. - Pagination info: `currentPage`, `pageSize`, `totalPages`, `totalRecords`. 4. **API Response Wrapper**: Use the provided generic `ApiResponse<T>` class to standardize all API responses with `responseCode`, `message`, `errorDetails`, `data`, and ISO 8601 `timestamp`. 5. **Repository Layer**: Implement `ClaimsRepository` as a Spring Data JPA repository for the `ActionMemo` entity. 6. **Service Layer**: - Define the interface `MemoService` with method `PendingMemoResponse getMemoListByStatus(PendingMemoRequest request);`. - Implement this interface in `MemoServiceImpl`: - Handle pagination, normalize filters (convert date ranges to IST, clean filters). - Query `actionMemosRepository` applying filters; if all filters are empty, fetch all memos. - Map queried data to a list of `MemoResponse`. - Construct and return `PendingMemoResponse` with data and pagination metadata. - Use SLF4J for logging throughout the service. 7. **Controller Layer**: Create `ClaimsServiceController` with a single endpoint: - `@PostMapping("/memoListByStatus")` accepting a `@Valid` `@RequestBody` `PendingMemoRequest`. - Calls `MemoService.getMemoListByStatus()` and returns an `ApiResponse<PendingMemoResponse>`. 8. **Global Exception Handler**: Use the provided class that: - Handles `SQLException`, `DataAccessException`, `RuntimeException`, general `Exception`, and `MethodArgumentNotValidException`. - Logs exceptions appropriately. - Returns standardized `ApiResponse` failures with descriptive messages. **Additional requirements:** - Apply validation annotations properly in request classes. - Use Lombok annotations for cleaner model classes. - Add detailed SLF4J logs in service implementation. - Follow best Spring Boot practices for layered architecture. # Steps 1. Design the `ActionMemo` entity mapping to database structure. 2. Create `PendingMemoRequest` and apply validation constraints. 3. Define `PendingMemoResponse` and `MemoResponse` DTOs. 4. Implement `ClaimsRepository` using Spring Data JPA. 5. Define `MemoService` interface and implement it in `MemoServiceImpl` with filtering, paging, and logging. 6. Create `ClaimsServiceController` with POST endpoint. 7. Integrate and configure the global exception handler. # Output Format Provide full Java class implementation snippets with proper package declarations and import statements for each component: - Entity class - Request and response DTO classes - Repository interface - Service interface and implementation - Controller class - Global exception handler Use annotations and Lombok where specified. Each class should be properly documented and structured for use in a Spring Boot project. # Notes - Dates should be handled and converted correctly to IST time zone where needed. - Ensure validation error messages are meaningful. - Logging statements must include method entry, parameters, and exception details if any. - Pagination defaults can be assumed but expose pagination fields to clients for flexibility. - The controller method should return `ApiResponse.success()` wrapping the `PendingMemoResponse` on success.
