Template class, let us write a simple example, which will implement all the CRUD operations on the following Student table. CREATE TABLE Student. ID INT NOT NULL AUTOINCREMENT. NAME VARCHAR2. 0 NOT NULL. AGE INT NOT NULL. PRIMARY KEY ID. Before proceeding, let us have a working Eclipse IDE in place and take the following steps to create a Spring application Steps. Description. 1Create a project with a name Spring. Example and create a package com. Add required Spring libraries using Add External JARs option as explained in the Spring Hello World Example chapter. Add Spring JDBC specific latest libraries mysql connector java. You can download required libraries if you do not have them already. Create DAO interface Student. DAO and list down all the required methods. Though it is not required and you can directly write Student. JDBCTemplate class, but as a good practice, lets do it. Create other required Java classes Student, Student. Mapper, Student. JDBCTemplate and Main. App under the com. Make sure you already created Student table in TEST database. Also make sure your My. SQL server is working fine and you have readwrite access on the database using the give username and password. Create Beans configuration file Beans. The final step is to create the content of all the Java files and Bean Configuration file and run the application as explained below. Following is the content of the Data Access Object interface file Student. DAO. java. package com. List. import javax. Data. Source. public interface Student. DAO. This is the method to be used to initialize. Data. SourceData. Source ds. This is the method to be used to create. Student table. public void createString name, Integer age. This is the method to be used to list down. Student table corresponding. Student get. StudentInteger id. This is the method to be used to list down. Student table. public Listlt Student list. Students. This is the method to be used to delete. Student table corresponding. Integer id. This is the method to be used to update. Student table. public void updateInteger id, Integer age. Following is the content of the Student. Student. private Integer age. String name. private Integer id. AgeInteger age. Integer get. Age. NameString name. String get. Name. IdInteger id. Integer get. Id. Following is the content of the Student. Mapper. java file. Result. Set. import java. SQLException. import org. Row. Mapper. public class Student. Mapper implements Row. Mapperlt Student. Student map. RowResult. Set rs, int row. Num throws SQLException. Student student new Student. Idrs. get. Intid. Namers. get. Stringname. Agers. get. Intage. Following is the implementation class file Student. JDBCTemplate. java for the defined DAO interface Student. DAO. package com. List. import javax. Data. Source. import org. Jdbc. Template. public class Student. JDBCTemplate implements Student. DAO. private Data. Source data. Source. Jdbc. Template jdbc. Template. Object. Data. SourceData. Source data. Source. Source data. Source. Template. Object new Jdbc. Templatedata. Source. String name, Integer age. String SQL insert into Student name, age values ,. Template. Object. SQL, name, age. System. Created Record Name name Age age. Student get. StudentInteger id. String SQL select from Student where id. Student student jdbc. Template. Object. For. ObjectSQL. new Objectid, new Student. Mapper. return student. Listlt Student list. Students. String SQL select from Student. List lt Student students jdbc. Template. Object. SQL, new Student. Mapper. return students. Integer id. String SQL delete from Student where id. Template. Object. SQL, id. System. Deleted Record with ID id. Integer id, Integer age. String SQL update Student set age Template. Object. SQL, age, id. System. Updated Record with ID id. Following is the content of the Main. App. java file. package com. List. import org. Application. Context. Class. Path. Xml. Application. Context. Student. JDBCTemplate. Main. App. public static void mainString args. Application. Context context new Class. Path. Xml. Application. ContextBeans. xml. Student. JDBCTemplate student. JDBCTemplate. Student. JDBCTemplatecontext. Beanstudent. JDBCTemplate. System. out. println Records Creation. JDBCTemplate. createZara, 1. JDBCTemplate. createNuha, 2. JDBCTemplate. createAyan, 1. System. out. println Listing Multiple Records. Listlt Student students student. JDBCTemplate. list. Students. for Student record students. System. out. printID record. Id. System. out. Name record. Name. System. Age record. Age. System. out. Updating Record with ID 2. JDBCTemplate. update2, 2. System. out. println Listing Record with ID 2. Student student student. JDBCTemplate. get. Student2. System. ID student. Id. System. Name student. Name. System. Age student. Age. Following is the configuration file Beans. UTF 8. lt beans xmlns http www. XMLSchema instance. Location http www. Initialization for data source. Source. class org. Driver. Manager. Data. Source. lt property name driver. Class. Name value com. Driver. lt property name url value jdbc mysql localhost 3. TEST. lt property name username value root. Definition for student. JDBCTemplate bean. JDBCTemplate. class com. Student. JDBCTemplate. Source ref data. Source. Once you are done creating the source and bean configuration files, let us run the application. If everything is fine with your application, it will print the following message. Records Creation. Created Record Name Zara Age 1. Created Record Name Nuha Age 2. Created Record Name Ayan Age 1. Listing Multiple Records. ID 1, Name Zara, Age 1. ID 2, Name Nuha, Age 2. ID 3, Name Ayan, Age 1. Updating Record with ID 2. Updated Record with ID 2. Listing Record with ID 2. ID 2, Name Nuha, Age 2. You can try and delete the operation yourself, which we have not used in the example, but now you have one working application based on Spring JDBC framework, which you can extend to add sophisticated functionality based on your project requirements. There are other approaches to access the database where you will use Named. Parameter. Jdbc. Template and Simple. Jdbc. Template classes, so if you are interested in learning these classes then kindly check the reference manual for Spring Framework.
