JdbcTemplate.execute('DROP TABLE IF EXISTS Friends'); jdbcTemplate.execute('CREATE TABLE Friends(Id INT, Name VARCHAR(30), ' + 'Age INT)'); With the JdbcTemplate's execute method, we create a Friends table. JdbcTemplate.update('INSERT INTO Friends VALUES(1, 'Paul', 27)'); We use the JdbcTemplate's update method to insert a statement. Spring JdbcTemplate: Performing insert, update, delete, select operations February 15, 2016 0 This article explains JdbcTemplate in Spring and using it to perform CRUD operations.

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.

Sep 11, 2020 The JDBC template is the main API through which we'll access most of the functionality that we're interested in: creation and closing of connections; executing statements and stored procedure calls; iterating over the ResultSet and returning results; Firstly, let’s start with a simple example to see what the JdbcTemplate can do.

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'sexecute() method, we create a Friends table.

We use the JdbcTemplate'supdate() method to insert a statement.

In this SQL statement, we select a friend identified by its ID.

The JdbcTemplate'squeryForObject() method executes the SQL query andreturns the result object. The result object is mapped to the Friendobject using the BeanPropertyRowMapper.

With the JdbcTemplate'squery() 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.
