In this tutorial, we will learn how to connect to the database and execute CRUD SQL queries using Spring 4 JdbcTemplate. Java base configuration is used to load the JdbcTemplate, here we are not using XML base configuration for JdbcTemplate.

May 09, 2017 In this Spring CRUD Example, we will build a Simple Spring Application and perform CRUD operations using Spring JdbcTemplate.We will create a simple Employee management application which has abilities to create a new employee, update the existing employee, get a particular employee/ all employee and finally delete the existing employee. In the previous example you have seen Spring JDBC query example using JdbcDaoSupport In this page you will see how to query single column using JdbcTemplate.

Spring 4 Eclipse project set up Tools and Technologies

1. Apache Maven 3.0.4
2. JDK 1.8
3. Spring core, Spring webmvc and Spring context (4.1.4.RELEASE)
4. mysql(5.1.31)

Database table

Use below SQL script to create 'trn_person' table in the database.

pom.xml

As we are using Maven project. Let's define the spring 4 specific maven dependencies.

Person Pojo

This is simple Person pojo class which contains different attributes like personId, firstName, lastName and age.

application.properties

Create 'application.properties' file under /resources folder. Define data source configuration properties like jdbc driverClassName, url, username and password.

Spring 4 Application Configuration

@Configuration annotation imports the Spring configuration. @Configuration objects are managed as Spring beans within the container, imported configurations are used to injected using @Autowired or @Inject.

@ComponentScan is equivalent to <context:component-scan base-package='...' used to lookup the beans and components classes in the spring context.

@PropertySource Annotation use to provide a convenient and declarative mechanism for adding a PropertySource to Spring's Environment.

To declare a bean, simply annotate a method with the @Bean annotation. When JavaConfig encounters such a method, it will execute that method and register the return value as a bean within a BeanFactory. Here we have registered JdbcTemplate and DataSource beans.

PersonService Interface

Creates PersonService interface along with CRUD methods.

Select For Update Jdbc Example

1. Create new Person entity.
2. Edit Person entity.
3. Delete Person entity.
4. Returns Person entity identified by the given id.
5. Returns all Person entities

PersonService Implementation

Mark PersonServiceImpl class as 'personService' using @Service annotation. Use @Autowired annotation to autowire PersonDao bean.

PersonDao Interface

Creates PersonDao interface.

PersonDao implementation

PersonDaoImpl marked with @Repository annotation, It allows the component scanning to find and configure the respected DAO. @Autowired JdbcTemplate to access to a persistence resource.

Oracle Sql Select For Update App.java

To create standalone Spring Application Context, We are using AnnotationConfigApplicationContext which helps to register all the beans generated by the configuration class (@Configuration) at Spring runtime.

Select For Update Spring Jdbctemplate 2020

Use AbstractApplicationContext.getBean(String name) method is used to get bean object( 'personService') from Spring application context.

Once you get the 'personService' instance perform different CRUD operations.
