Spring Boot + Apache Camel JDBC component + MySQL - Hello World Example

In previous tutorial we had implemented Apache Camel + Spring SQL Component Example for inserting and retrieving records from MySQL. In that example we had made use of Spring XML configuration. In this tutorial we will be making use of Spring Boot and Apache Camel JDBC Component for inserting and retrieving records from MySQL
The JDBC component enables us to access databases through JDBC, where SQL queries (SELECT) and operations (INSERT, UPDATE, etc) are sent in the message body. This component uses the standard JDBC API, unlike the SQL Component component, which uses spring-jdbc.
The Maven Project is as follows-
Apache Camel Spring Boot JDBC Component Maven
The pom.xml is as follows-
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="" xmlns:xsi=""


	<description>Demo project for Spring Boot</description>

		<relativePath /> <!-- lookup parent from repository -->




In the file specify the datasource properties
Create the schema-mysql.sql file and specify the initialization scripts-

CREATE TABLE employee (
  empName VARCHAR(100) NOT NULL

Create the Employee Domain class
package com.javainuse.model;

public class Employee {

	private String empId;
	private String empName;

	public String getEmpId() {
		return empId;

	public void setEmpId(String empId) {
		this.empId = empId;

	public String getEmpName() {
		return empName;

	public void setEmpName(String empName) {
		this.empName = empName;

	public String toString() {
		return "Employee [empId=" + empId + ", empName=" + empName + "]";


Create the Service class where will be configuring the route-

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.sql.DataSource;

import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.javainuse.model.Employee;

public class EmployeeServiceImpl extends RouteBuilder {

	DataSource dataSource;

	public DataSource getDataSource() {
		return dataSource;

	public void setDataSource(DataSource dataSource) {
		this.dataSource = dataSource;

	public void configure() throws Exception {

		from("direct:select").setBody(constant("select * from Employee")).to("jdbc:dataSource")
				.process(new Processor() {
					public void process(Exchange xchg) throws Exception {
						ArrayList<Map<String, String>> dataList = (ArrayList<Map<String, String>>) xchg.getIn()
						List<Employee> employees = new ArrayList<Employee>();

						for (Map<String, String> data : dataList) {

							Employee employee = new Employee();



		from("direct:insert").process(new Processor() {
			public void process(Exchange xchg) throws Exception {
				Employee employee = xchg.getIn().getBody(Employee.class);
				String query = "INSERT INTO employee(empId,empName)values('" + employee.getEmpId() + "','"
						+ employee.getEmpName() + "')";

Create the Controller class where will be calling the route-
package com.javainuse.controller;

import java.util.List;

import org.apache.camel.ProducerTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.javainuse.model.Employee;

public class EmployeeController {

	ProducerTemplate producerTemplate;

	@RequestMapping(value = "/employees", method = RequestMethod.GET)
	public List<Employee> getAllEmployees() {
		List<Employee> employees = producerTemplate.requestBody("direct:select", null, List.class);
		return employees;


	@RequestMapping(value = "/employees", consumes = "application/json", method = RequestMethod.POST)
	public boolean insertEmployee(@RequestBody Employee emp) {
		producerTemplate.requestBody("direct:insert", emp, List.class);
		return true;
Finally create the Spring Boot Main class with the SpringBootApplication Annotation
package com.javainuse;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

public class SpringBootJdbcApplication {

	public static void main(String[] args) {, args);
Start the application.
Send a POST request to insert new employee detail-
Apache Camel Spring Boot POST Request
Send a GET request to retrieve all employee details-
Apache Camel Spring Boot GET Request
