Example to Update Database in Spring JDBC

By Arvind Rai, November 05, 2013

In this page, we will learn how to update database in spring JDBC. We can update database using JdbcTemplate.update(). The SQL query will have placeholder (?) to take input for update. In our example we have taken a simple example to present the demo for database update.

FarmarDao.java

package com.concretepage.dao;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
@Repository
public class FarmarDao {
	private JdbcTemplate jdbcTemplate;
    @Autowired
    public void setDataSource(DataSource dataSource) {
        this.jdbcTemplate = new JdbcTemplate(dataSource);
    }
    public void setAge(int age, int id){
    	String sql = "update farmar set age =? where id=?";
    	this.jdbcTemplate.update(sql,age,id);
    }
}

SpringTest.java

package com.concretepage;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.concretepage.dao.FarmarDao;
public class SpringTest {
	public static void main(String[] args) {
		ApplicationContext  context = new ClassPathXmlApplicationContext("spring.xml");
		FarmarDao farmar = (FarmarDao)context.getBean("farmarDao");
		farmar.setAge(30, 1);
		System.out.println("Done");
	}
}

Table Schema

CREATE TABLE 'farmar' (
	'id' INT(10) NULL DEFAULT NULL,
	'name' VARCHAR(50) NULL DEFAULT NULL,
	'age' INT NULL DEFAULT NULL
)
COLLATE='latin1_swedish_ci'
ENGINE=InnoDB;
