SQL Stored Procedure in Spring
Previous Home Next

The StoredProcedure class is a superclass for object abstractions of RDBMS stored procedures. This class is abstract, and its various execute(..) methods have protected access, preventing use other than through a subclass. The SimpleJdbcCall class can be used to call a stored procedure with IN and OUT parameters. You can use this approach while working with either of the RDBMS like Apache, Derby, DB2, MySQL, Microsoft SQL Server, Oracle, and Sybase.

The inherited sql property will be the name of the stored procedure in the RDBMS. To define a parameter for the StoredProcedure class, you use an SqlParameter or one of its subclasses. You must specify the parameter name and SQL type in the constructor like in the following code . The SQL type is specified using the java.sql.Types constants.

new SqlParameter("in_id", Types.NUMERIC),
new SqlOutParameter("out_name", Types.VARCHAR),

The first line with the SqlParameter declares an IN parameter. IN parameters can be used for both stored procedure calls and for queries using the SqlQuery and its subclasses covered in the following section. The second line with the SqlOutParameter declares an out parameter to be used in the stored procedure call. There is also an SqlInOutParameter for InOut parameters, parameters that provide an in value to the procedure and that also return a value.

Technologies used to run this Application.
  1. Spring 3.0
  2. Eclipse IDE
  3. JDK 1.6
  4. MySql Workbench 6.2
Example of Stored Procedure with Spring

First you make a table in Database Mysql Workbench like employee. The code of table as given below:

CREATE TABLE `employee` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(45) NOT NULL,
  `salary` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`)
) 

Now make a Stored Procedure with any name like emp_info as shown above figure.

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `emp_info`(
in ide integer,
out emp_name varchar(45),
out emp_salary integer)
BEGIN
select name, salary 
into emp_name, emp_salary
from employee where id=ide;
END$$
DELIMITER ;

Let us have working Eclipse IDE in place and follow the following steps to create a Spring application:

Step1. Now you create a simple Java Project using Eclipse IDE. Follow the option File -> New -> Project and finally select Java Project wizard from the wizard list. Now name your project as SpringwithStoredProcedure using the wizard window as given below.

Add spring jar files

Step2. Now add spring jar in your project, To do this, right click on your project name SpringwithStoredProcedure and then follow the following option available in context menu: Build Path -> Configure Build Path to display the Java Build Path window as given below. There are some jar files required to run this application, To load the jar files in eclipse IDE, Right click on your project - Build Path - Add external archives - select all the required jar files - finish.

  1. antlr-runtime-3.0.1
  2. org.springframework.aop-3.1.0
  3. org.springframework.asm-3.1.0.
  4. org.springframework.aspects-3.1.0.
  5. org.springframework.beans-3.1.0.
  6. org.springframework.context.support-3.1.0.
  7. org.springframework.context-3.1.0.
  8. org.springframework.core-3.1.0.
  9. spring-expression-3.1.0.RELEASE.jar
  10. com.springsource.org.aopalliance-1.0.0.jar
  11. org.apache.commons.logging-1.1.1.jar
  12. org.springframework.jdbc-3.0.0.M2.jar
  13. org.springframework.transaction-3.1.0.RELEASE.jar
  14. mysql-connector-java-5.1.23-bin.jar
  15. commons-dbcp-1.4.jar
  16. ojdbc14.jar
Create Java class file

Step3. Now you create simply java file with any name. First we need to create a package with any name like com.r4r. To do this, Right click on src in package explorer section and follow the option : New -> Package. and then Right click on package(com.r4r) - New - class - Write the class name e.g. Employee - finish. Write the following code:

package com.r4r;
public class Employee {
	private int id;  
	private String name;  
	private int salary;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getSalary() {
		return salary;
	}
	public void setSalary(int salary) {
		this.salary = salary;
	}
}

Step4. Now you create another Java class named EmployeeDao.java.

package com.r4r;

import java.util.Map;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;
import org.springframework.jdbc.core.namedparam.SqlParameterSource;
import org.springframework.jdbc.core.simple.SimpleJdbcCall;
import org.springframework.stereotype.Repository;

@Repository
public class EmployeeDao {
	private SimpleJdbcCall simpleJdbcCall;

@Autowired
    public void setDataSource(DataSource dataSource) {
this.simpleJdbcCall = 
	new SimpleJdbcCall(dataSource).withProcedureName("emp_info");
    }
  public Employee getEmployee(int id){
   SqlParameterSource in = new MapSqlParameterSource().addValue("ide", id); 
		Map<String,Object> out = simpleJdbcCall.execute(in);
		Employee emp = new Employee();
		emp.setName((String)out.get("emp_name"));
		emp.setSalary((Integer)out.get("emp_salary"));
		return emp;
    }
}

Step5. Now create the xml file click on src- new -file -give the file name like applicationContext.xml then finish.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    
    
    <bean id="dataSource" 
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/amit"/>
        <property name="username" value="root"/>
        <property name="password" value=""/>
    </bean>
    
    
    <bean id="employeeDao" class="com.r4r.EmployeeDao">
        <property name="dataSource" ref="dataSource"/>
    </bean>
</beans>

Step6.Now Create the java Main class (Test.java).

package com.r4r;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
	public static void main(String[] args) {
		ApplicationContext  context = 
		new ClassPathXmlApplicationContext("applicationContext.xml");
   EmployeeDao employeeDao = (EmployeeDao)context.getBean("employeeDao");
		Employee emp = employeeDao.getEmployee(101);
		System.out.println(emp.getName());
		System.out.println(emp.getSalary());
	}
}
Run Application

Now run the Application you see the following output:
