In the previous tutorial, I introduced you to the concept of a transaction in the database, which helps us to ensure data integrity and consistency. Spring also supports us to manage transactions, allowing us to focus on developing business logic without worrying about the integrity… Read More
In this tutorial, I will show you how to read properties files in Spring using the util namespace. First, I will create a Maven project as an example: The contents of the Application class are as follows:
|
1 2 3 4 5 6 7 8 9 10 11 |
package com.huongdanjava.spring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Application { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); } } |
I will use Java 17 for this… Read More
In this tutorial, I will show you how to read file properties in Spring using the context namespace. But first, let’s create an example project. I will use Java 17 for this example:
|
1 2 3 4 |
<properties> <maven.compiler.source>17</maven.compiler.source> <maven.compiler.target>17</maven.compiler.target> </properties> |
Spring framework dependency:
|
1 2 3 4 5 |
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>6.0.3</version> </dependency> |
Class Application:
|
1 2 3 4 5 6 7 8 9 10 11 |
package com.huongdanjava.spring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Application { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); } } |
In our example, the… Read More
In Java, we inherit one object using the abstract keyword, Spring also supports us to do the same thing in itself. This tutorial will show you how to use bean inheritance in Spring. OK, first we need to have a Maven project to work on.… Read More
We already know how to get an object from the Spring container using the getBean() method but sometimes we have the opposite need. That is, we want to use the Spring container in our object to have access to other objects in its container. Is… Read More
In my tutorials about the Spring framework, I often use the object of the ApplicationContext interface as a Spring container to call the object that I need to retrieve. For example, in the previous tutorial:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
package com.huongdanjava.springbeanautowiring; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Application { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml"); Room room = (Room) context.getBean("room"); if (room.getTable() != null) { System.out.println(room.getTable().toString()); } } } |
But in fact, Spring also provides us with another… Read More
The nature of Spring is to create objects in its container so that when you need an object, you can call the Spring container to get that object. Therefore, Spring seeks all the ways to support us in the creation of objects in the container… Read More
Injecting this object into another object in Spring is very common when you work with projects that use the Spring framework. In my previous tutorial, I mentioned Spring’s ref attribute to include a Shape object into a Drawing object, in this tutorial I’ll talk about… Read More
In JPA, the EntityManagerFactory object is an entity management object that manages the connection to the database. Using Spring to manage this object will help us a lot in developing Java applications that use JPA. In this tutorial, I will guide you on how to… Read More
In this tutorial, I would like to introduce to you all how to use properties in Spring with @Value annotation. First of all, we need a Maven project for example: I will use Java 17 for this example:

1 2 3 4 |
<properties> <maven.compiler.source>17</maven.compiler.source> <maven.compiler.target>17</maven.compiler.target> </properties> |
Spring framework dependency:
|
1 2 3 4 5 |
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>6.0.3</version> </dependency> |
HelloWorld class:… Read More
