You already know how to initialize the bean in the Spring container using the XML file in the previous tutorial. In addition to this, Spring also supports us to initialize the bean using the @Configuration annotation in the Java code. Let’s see how to initialize… Read More
In the tutorial on Bean autowiring in Spring framework, you know in the case of byType autowire, we cannot declare more than one bean of the same dependency in Spring’s container. Because in this case, Spring does not know what bean to use for autowire.… Read More
In the previous tutorial on the bean autowiring using the @Autowired annotation, I mentioned that the AutowiredAnnotationBeanPostProcessor object is used to dynamically place objects that depend on the dependent object. Perhaps some of you are wondering how this object can do that, right? Me too,… Read More
In my tutorial Bean autowiring in Spring framework, I showed to you all three ways to automatically put an object dependent on a dependent object without having to use the ref, idref, or list attributes. In this tutorial, I will introduce you another way of… Read More
I’ve introduced you to reading the properties of files in Spring using the PropertyPlaceholderConfigurer object, the util namespace, the context namespace. All of the above, we need to declare in Spring’s configuration file. In this tutorial, I introduce you all to another way to read the… Read More
Spring provides us with several ways to read our application’s configuration files: properties files. In this tutorial, I will tell you the most common way is to use the PropertyPlaceholderConfigurer object. First, I will create a Maven project as an example: With the Application class… Read More
Apart from initializing the bean in the Spring container using an XML file or using the @Configuration annotation, we can also initialize the bean using Spring’s auto component scan. How is it in details? I will tell you in this tutorial. First, I will create… Read More
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 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"); } } |
Spring dependency:
|
1 2 3 4 5 6 7 |
<dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.0.4.RELEASE</version> </dependency> </dependencies> |
In my example, the spring.xml… 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. Spring framework dependency:
|
1 2 3 4 5 6 7 |
<dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.0.4.RELEASE</version> </dependency> </dependencies> |
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 spring.xml file is the Spring configuration file and the… Read More
