In this tutorials I am going to show you how to work with Spring Boot JdbcTemplate using MySql Database.
Spring Boot JdbcTemplate :
Technologies :
This is yet another post of using jdbctemplate to fetch records from DB.In this post we will see how we can perform different crud operations using jdbctemplate.We will be creating examples of how to create and read data from DB using spring jdbc provided jdbctemplate.We will be using the artifact spring-boot-starter-jdbc provided by spring boot to configure our spring jdbc configurations. May 09, 2017 In this Spring CRUD Example, we will build a Simple Spring Application and perform CRUD operations using Spring JdbcTemplate.We will create a simple Employee management application which has abilities to create a new employee, update the existing employee, get a particular employee/ all employee and finally delete the existing employee.

Project Structure :
Spring Boot JdbcTemplate Example :
As part of this tutorials, I am going to implement a complete CRUD operations using Spring Boot JdbcTemplate.
Recommended :Spring JDBCTemplate Example
Defining all necessary data source, authentication credentials.
Database Preparation :
Create your mysql database (otp) and create below item table under otp database.
Created an item table, which represents all items and I am going to do all CRUD operations on this table.
Create Item Model to represent the above table.
Creating Item Repository :
This is the key class of our example, under which all CRUD operations are happening.
Create RestController to provide an endpoint to access from outside.
Application.java
Run it !
Access the Application :
Getting All Items :
http://localhost:8080/getAllItems
Add an Item :
http://localhost:8080/addItem?id=4&name=Refrigerator&category=Refrigerator
Getting All Items After adding :
http://localhost:8080/getAllItems
Delete an Item from the list :

In this tutorial, we show how to create a classic Spring application with JdbcTemplate.The application connects to a MySQL database and issues SQL statements using JdbcTemplate.
Spring is a popular Java application framework for developing enterprise applications in Java. It is also a very good integration systemthat helps glue together various enterprise components.
JdbcTemplate
is a library that helps programmers create applications that workwith relational databases and JDBC. It handles many tedious and error-prone low-level details such as handling transactions, cleaning up resources, and correctly handling exceptions. JdbcTemplate is shipped in Spring's spring-jdbc
module.
In the Maven build file, we provide the dependencies for the core of the Spring application, JdbcTemplate library, and MySQL driver.
This is a Friend
class. A row from the databasetable will be mapped to this class.
In the application context XML file, which we call my-beans.xml
, we define twobeans: data source bean and jdbcTemplate
bean. The data source bean contains the data source properties; the jdbcTemplate
refers to the dataSource
bean via the ref
attribute. The my-beans.xml
is located in the src/main/resources
subdirectory.
The SpringJdbcTemplateEx
sets up the Spring application.
From the my-beans.xml
file, we create the ApplicationContext
.Spring ApplicationContext
is a central interface to provide configuration for an application. ClassPathXmlApplicationContext
is an implementation ofthe ApplicationContext
that loads configuration definition from an XML file, which is located on the classpath.
From the application context, we get the jdbcTemplate
bean.
With the JdbcTemplate's
execute()
method, we create a Friends
table.
We use the JdbcTemplate's
update()
method to insert a statement.
In this SQL statement, we select a friend identified by its ID.
The JdbcTemplate's
queryForObject()
method executes the SQL query andreturns the result object. The result object is mapped to the Friend
object using the BeanPropertyRowMapper
.

With the JdbcTemplate's
query()
method, we retrieve allfriends and print them to the console.
This is the output of the example.
In this tutorial, we have created a classic Spring application that issued SQL statements with JdbcTemplate. The Spring application was configured in XML.You might also be interested in these related tutorials: JdbcTemplate tutorial,Introduction to Spring web applications,Spring Boot first web application, orJava tutorial.
