How to call Stored Procedure in Hibernate using Annotation

Calling stored procedure in Hibernate using Annotation 

Third approach to call DB stored procedure in hibernate 

By Calling getNamedQuery() method with the use of Annotation:- 

Steps for creating example to call a stored procedure using Native SQL in Hibernate:-

• At first, create a java project using eclipse and name it as StoredProcCallUsingHibernate.

• Inside src folder, create a package named com.gaurav.hibernate.beans.

• After that, create a java bean file named StudentAnnotatedBean and place the below corresponding code in that file.

• Now, Inside src folder create hibernate.cfg.xml file and place the below corresponding source code.

•  Now, in src folder, create a package com.gaurav.hibernate.procedurecall and place the ProcCallByNamedNativeQuery.java client program in that package which is available below.

• Create the Student table and insert the records in the database, then create the corresponding stored procedure which we are going to call using Hibernate

Note: If we are using annotations then in this case hibernate mapping file is not required.

Table Structure and Insert queries are available below:-

/*Table structure for table student */

DROP TABLE IF EXISTS student;

CREATE TABLE student (
  STUDENT_ID decimal(20,0) DEFAULT NULL,
  FIRSTNAME varchar(50) NOT NULL,
  LASTNAME varchar(50) NOT NULL,
  BIRTHDATE date DEFAULT NULL,
  TOTAL_MARKS decimal(20,0) DEFAULT NULL,
  DIVISION varchar(50) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

/*Data for the table student */


insert into student (STUDENT_ID,FIRSTNAME,LASTNAME,BIRTHDATE,TOTAL_MARKS,DIVISION) values ('1','Kumar','Gaurav','1978-05-12','920','FIRST');

insert into student (STUDENT_ID,FIRSTNAME,LASTNAME,BIRTHDATE,TOTAL_MARKS,DIVISION) values ('2','Gaurav','Kumar','1980-11-19','880','FIRST');


insert into student (STUDENT_ID,FIRSTNAME,LASTNAME,BIRTHDATE,TOTAL_MARKS,DIVISION) values ('3','Shivam','Kumar','1989-07-11','670','SECOND');

getStudentDetails() stored procedure. Below is the syntax for MySQL DB

DELIMITER $$

DROP PROCEDURE IF EXISTS test.getStudentDetails $$
CREATE PROCEDURE test.getStudentDetails
   (IN STUD_ID INT)
BEGIN
   SELECT *
   FROM STUDENT
   WHERE STUDENT_ID = STUD_ID;
END $$

DELIMITER ;

Below is the initial table status, after the table creation and record insertion:-

             * If we are using Annotated classes then we have two way to get SessionFactory object
              
               First Approach Using Annotation:-
               1. We can create sessionFactory object like below :-
                  SessionFactory sessionFactory = new AnnotationConfiguration().configure() .buildSessionFactory();
               2. We have to add below entry in hibernate configuration file for annotated class mapping
               <mapping class="package_name.annotated_classname"/>
              
               Second approach Using Annotation:-
               1. We need to create an instance of AnnotationConfiguration class like below :-
                  AnnotationConfiguration annotationConfiguration = new AnnotationConfiguration();
               2. We have to call addAnnotatedClass() method on AnnotationConfiguration object and we need to pass
                  the annotated class name.
               3. Then using AnnotationConfiguration class object we need to call buildSessionFactory()
                  for getting SessionFactory object.
                  annotationConfiguration.configure().buildSessionFactory();
                  Below I am using second approach. First approach i have commented and even commented entry is also available in configuration file in order to follow first approach.         
             */
            /*
             * SessionFactory sessionFactory = new
             * AnnotationConfiguration().configure().buildSessionFactory();
             */
            AnnotationConfiguration annotationConfiguration = new AnnotationConfiguration();

            annotationConfiguration
                    .addAnnotatedClass(StudentAnnotatedBean.class);

            SessionFactory sessionFactory = annotationConfiguration.configure()
                    .buildSessionFactory();
            session = sessionFactory.openSession();

            System.out.print("Procedure Invocation completed :- ");
            List<StudentAnnotatedBean> studentDataInList = retrieveStudentAnnotatedBean(2);

            if (studentDataInList != null) {
                for (StudentAnnotatedBean studentAnnotatedBean : studentDataInList) {
                    System.out.println("FIRSTNAME :- "
                            + studentAnnotatedBean.getFirstName());
                    System.out.println("LASTNAME :- "
                            + studentAnnotatedBean.getLastName());
                    System.out.println("BIRTHDATE :- "
                            + studentAnnotatedBean.getBirthDate());
                    System.out.println("TOTAL MARKS :- "
                            + studentAnnotatedBean.getTotalMarks());
                    System.out.println("DIVISION :- "
                            + studentAnnotatedBean.getDivision());
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            session.flush();
            session.close();

        }
    }
}
