To get last record in JPA Repository, we can typically sort on specific columns, such as an auto-incremented id or a timestamp. JPA doesn’t provide a built-in method to get last record but we can use a findFirstByOrderBy…Desc(), findTopByOrderBy…Desc(), findByOrderBy…Desc(Limit limit), Pagination, JPQL and Native SQL query. This topic will teach us how to get the last record in JPA Repository using several approaches.
Methods to Get Last Record in JPA Repository
1. Using findFirstByOrderBy…Desc()
Let us assume the timestamp column in a table. We want to get last record from the table using the JPA Repository by sorting that timestamp column creating the custom query method with this name findFirstByOrderByTimestampDesc() in the repository interface.
Example
import org.springframework.data.jpa.repository.JpaRepository;
public interface OrderRepository extends JpaRepository<OrderDetail, Long> {
OrderDetail findFirstByOrderByTimestampDesc();
}
- This findFirstByOrderByTimestampDesc() method orders the record in descending order and fetches the first one that will give the last inserted record.
2. Using findTopByOrderBy…Desc()
Let us assume the timestamp column in a table. We want to get last record from the table using the JPA Repository by sorting that timestamp column creating the custom query method with this name findTopByOrderByTimestampDesc() in the repository interface.
Example
import org.springframework.data.jpa.repository.JpaRepository;
public interface OrderRepository extends JpaRepository<OrderDetail, Long> {
OrderDetail findTopByOrderByTimestampDesc();
}
- This findTopByOrderByTimestampDesc() method orders the record in descending order and fetches the top one that will give the last inserted record.
3. Using findByOrderBy…Desc(Limit limit)
Let’s consider the timestamp column in a table then we will get the last record from the table using the JPA Repository by sorting that timestamp column creating a custom query method findByOrderByTimestampDesc(Limit limit) with Limit interface as a parameter.
Example
import org.springframework.data.domain.Limit;
import org.springframework.data.jpa.repository.JpaRepository;
public interface OrderRepository extends JpaRepository<OrderDetail, Long> {
OrderDetail findByOrderByTimestampDesc(Limit limit);
}
We need a Service class to call this method and then pass the Limit.of(1) to get last record from table.
Example
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Limit;
import org.springframework.stereotype.Service;
@Service
public class OrderServiceImpl implements OrderService {
@Autowired
private OrderRepository orderRepo;
@Override
public OrderDetail getLastOrderWithLimit() {
return orderRepo.findByOrderByTimestampDesc(Limit.of(1));
}
}
4. Using Pagination
We can get last record from the table using JPA Repository through pagination sorting in descending order.
Example
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;
@Service
public class OrderServiceImpl implements OrderService {
@Autowired
private OrderRepository orderRepo;
@Override
public OrderDetail getLastOrderWithPagination() {
Pageable lastPage = PageRequest.of(0, 1, Sort.by("timestamp").descending());
Page < OrderDetail > page = orderRepo.findAll(lastPage);
return page.getContent().get(0);
}
}
5. Using JPQL
We can get last record from the table using JPA Repository by specifying the explicit query using @Query.
Example
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
public interface OrderRepository extends JpaRepository<OrderDetail, Long> {
@Query("SELECT od FROM OrderDetail od ORDER BY od.timestamp DESC LIMIT 1")
OrderDetail findLastOrder();
}
6. Using Native SQL Query
We can get last record from the table using JPA Repository by specifying Native SQL query with ORDER BY and the LIMIT clauses.
Example
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
public interface OrderRepository extends JpaRepository<OrderDetail, Long> {
@Query(value = "SELECT * FROM order_detail od ORDER BY timestamp DESC LIMIT 1", nativeQuery = true)
OrderDetail findLastOrderNative();
}
Step-by-step to Guide Get Last Record in JPA Repository
Let’s create a Spring Boot Application step-by-step guide to get last record in the JPA Repository to fetch records from the database table. We will create an example to get last order record using API endpoints through the methods mentioned above.
These are the following steps:
- Create a Spring Boot Project
- Setup in the IDE
- Configure H2 Database
- Create a JPA Entity
- Create a Repository Interface
- Create a Service Interface
- Implement the Service Interface
- Create a Controller
- Run the Spring Boot Application
1. Create a Spring Boot Project
We are creating a Spring Boot Project from the web tool Spring Initializr. By Providing details for the project and select the following Maven dependencies:
- Spring Web
- Spring Data JPA
- H2 Database
- Lombok
2. Setup in the IDE
We use Eclipse IDE to set up and configure the created Spring Boot Project. You can use other IDE to set up and configure the Spring Boot project.
Project Structure of Spring Boot
This image shows the project structure of Spring Boot in Eclipse IDE.
Maven Dependency
Here is the complete maven dependencies file pom.xml for the project which will implement methods to get the last record in the JPA Repository.

3. Configure H2 Database
We are going to configure the H2 database connection in the application.properties file.
application.properties
#H2 Database Configuration
spring.datasource.url=jdbc:h2:mem:test
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update
spring.h2.console.enabled=true
4. Create a JPA Entity
Let’s create a JPA Entity class. For example, consider an OrderDetail entity and use Lombok for generating setter and getter methods, a constructor, etc.
OrderDetail.java
package com.springjava.entity;
import java.time.LocalDateTime;
import org.hibernate.annotations.CreationTimestamp;
import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import lombok.Data;
@Data
@Entity
public class OrderDetail {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private Long customerId;
private Double amount;
@CreationTimestamp
private LocalDateTime timestamp;
}
5. Create a Repository Interface
Create a repository interface for the OrderDetail JPA Entity class that interface extends the JpaRepository interface to perform persistence operations on the order_detail database table.
OrderRepository.java
package com.springjava.repository;
import org.springframework.data.domain.Limit;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.springjava.entity.OrderDetail;
public interface OrderRepository extends JpaRepository < OrderDetail, Long > {
OrderDetail findFirstByOrderByTimestampDesc();
OrderDetail findTopByOrderByTimestampDesc();
OrderDetail findByOrderByTimestampDesc(Limit limit);
@Query("SELECT od FROM OrderDetail od ORDER BY od.timestamp DESC LIMIT 1")
OrderDetail findLastOrder();
@Query(value = "SELECT * FROM order_detail od ORDER BY timestamp DESC LIMIT 1", nativeQuery = true)
OrderDetail findLastOrderNative();
}
6. Create a Service Interface
Create a Service interface OrderService with some method declaration.
OrderService.java
package com.springjava.service;
import java.util.List;
import com.springjava.entity.OrderDetail;
public interface OrderService {
void saveAll(List < OrderDetail > orderList);
OrderDetail getLastOrderWithFirst();
OrderDetail getLastOrderWithTop();
OrderDetail getLastOrderWithLimit();
OrderDetail getLastOrderWithPagination();
OrderDetail getLastOrderWithJPQL();
OrderDetail getLastOrderWithNative();
}
7. Implement the Service Interface
Implement the OrderService interface in the OrderServiceImpl class. This class is annotated with @Service annotation, where we inject OrderRepository to call all its methods.
OrderServiceImpl.java
package com.springjava.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Limit;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.domain.Sort;
import org.springframework.stereotype.Service;
import com.springjava.entity.OrderDetail;
import com.springjava.repository.OrderRepository;
@Service
public class OrderServiceImpl implements OrderService {
@Autowired
private OrderRepository orderRepo;
@Override
public void saveAll(List < OrderDetail > orderList) {
orderRepo.saveAll(orderList);
}
@Override
public OrderDetail getLastOrderWithFirst() {
return orderRepo.findFirstByOrderByTimestampDesc();
}
@Override
public OrderDetail getLastOrderWithTop() {
return orderRepo.findTopByOrderByTimestampDesc();
}
@Override
public OrderDetail getLastOrderWithLimit() {
return orderRepo.findByOrderByTimestampDesc(Limit.of(1));
}
@Override
public OrderDetail getLastOrderWithPagination() {
Pageable lastPage = PageRequest.of(0, 1, Sort.by("timestamp").descending());
Page < OrderDetail > page = orderRepo.findAll(lastPage);
return page.getContent().get(0);
}
@Override
public OrderDetail getLastOrderWithJPQL() {
return orderRepo.findLastOrder();
}
@Override
public OrderDetail getLastOrderWithNative() {
return orderRepo.findLastOrderNative();
}
}
8. Create a Controller
Create a controller class OrderController. This is annotated with @RestController to make this class a RestController.
OrderController.java
package com.springjava.controller;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.springjava.entity.OrderDetail;
import com.springjava.service.OrderService;
@RestController
@RequestMapping("/api/order")
public class OrderController {
@Autowired
private OrderService orderService;
@PostMapping("/save-all")
public ResponseEntity < ? > save(@RequestBody List < OrderDetail > orderList) {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
orderService.saveAll(orderList);
respOrder.put("status", 1);
respOrder.put("message", "Record is Saved Successfully!");
return new ResponseEntity < > (respOrder, HttpStatus.CREATED);
}
@GetMapping("/last-order-with-first")
public ResponseEntity < ? > getLastOrderWithFirst() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithFirst();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
@GetMapping("/last-order-with-top")
public ResponseEntity < ? > getLastOrderWithTop() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithTop();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
@GetMapping("/last-order-with-limit")
public ResponseEntity < ? > getLastOrderWithLimit() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithLimit();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
@GetMapping("/last-order-with-pagination")
public ResponseEntity < ? > getLastOrderWithPagination() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithPagination();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
@GetMapping("/last-order-with-jpql")
public ResponseEntity < ? > getLastOrderWithJPQL() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithJPQL();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
@GetMapping("/last-order-with-native")
public ResponseEntity < ? > getLastOrderWithNative() {
Map < String, Object > respOrder = new LinkedHashMap < String, Object > ();
OrderDetail lastOrder = orderService.getLastOrderWithNative();
if (lastOrder != null) {
respOrder.put("status", 1);
respOrder.put("data", lastOrder);
return new ResponseEntity < > (respOrder, HttpStatus.OK);
} else {
respOrder.clear();
respOrder.put("status", 0);
respOrder.put("message", "Data is not found");
return new ResponseEntity < > (respOrder, HttpStatus.NOT_FOUND);
}
}
}
9. Run the Spring Boot Application
Right-click this Spring Boot application on the DemoApplication.java, then click Run As and select Java Application.
H2 Database Console
To check the H2 database console use the URL http://localhost:[server_port]/h2-console.
JSON Array
We are creating a sample JSON Array to test the API http://localhost:8080/api/order/save-all.
[
{
"customerId": 1,
"amount": 700
},
{
"customerId": 1,
"amount": 800
},
{
"customerId": 2,
"amount": 900
},
{
"customerId": 3,
"amount": 800
}
]

Conclusion
To get the last record in JPA Repository of Spring Data JPA, We can use:
1. Sort by a timestamp field using findFirstByOrderByTimestampDesc()
2. Sort by a timestamp field using findTopByOrderByTimestampDesc()
3. Sort by a timestamp field using findByOrderByTimestampDesc(Limit limit)
4. Sort by a timestamp field using paging and sorting with PageRequest and Sort
5. Sort by a timestamp field using JPQL
6. Sort by a timestamp field using Native SQL query
