How to use Sticky Configured 6 framework in the Java library
Overview:
Sticky Configured 6 is a powerful Java class library that allows developers to easily configure and read the application files of the application.This article will introduce how to use the Sticky Configured 6 framework in the Java library and provide some example code to help you better understand.
1. Introduce Sticky Configured 6 framework:
First, you need to import the Sticky Configured 6 framework into your Java project.You can download the latest Sticky Configured 6 framework from the official website (https://stickycode.readthedocs.io/docs-dex/), and then add it to your project dependence.
2. Create configuration files:
Before using Sticky Configured 6, you need to create a configuration file to store the configuration information for the application.The configuration file can be .properties file, .yml file or any other support format.Suppose our configuration file is named Config.properties and includes the following:
properties
database.url=jdbc:mysql://localhost:3306/mydatabase
database.username=admin
database.password=123456
3. Create configuration class:
Use Sticky Configured 6 in the Java library. You need to create a Java class corresponding to the configuration file, and use the @Configured annotation to mark the class.The annotation will tell the Sticky Configured 6 framework to bind the value of the configuration file to the corresponding field.For example, we can create a class called DataBaseConfig's database configuration, as shown below:
import net.stickycode.configured.ConfigurationRepository;
import net.stickycode.configured.ConfigurationSource;
import net.stickycode.configured.DefaultConfigurationRepository;
import net.stickycode.configured.strategy.source.PropertiesConfigurationSource;
@Configured
public class DatabaseConfig {
@Configured
private String url;
@Configured
private String username;
@Configured
private String password;
public DatabaseConfig() {
ConfigurationRepository repository = new DefaultConfigurationRepository();
ConfigurationSource source = new PropertiesConfigurationSource("config.properties");
repository.bind(this).using(source).initialize();
}
// Getter and setter methods
}
In the above code, we used the @Configured annotation to mark the field URL, username, and password.Then, in the constructive method of the class, we create a defaultConfigurationRePOSITORY instance and use the PropertiesconfigurationSource to load the configuration file.Next, we bind the values of the configuration file to the corresponding field by calling the repository.bind (this) .using (source) .initialize ().
4. Use the configuration class:
Once the configuration class is binding correctly, you can use the class in other classes to read the configuration value in other classes.For example, we can create a class called DataBaseClient and use the above DataBaseConfig class to obtain the database configuration information, as shown below:
public class DatabaseClient {
public void connect() {
DatabaseConfig config = new DatabaseConfig();
String url = config.getUrl();
String username = config.getUsername();
String password = config.getPassword();
// Do some operations connecting the database ...
}
}
In the above code, we created a new DataBaseConfig instance and obtained the URL, username and password of the database by calling the corresponding Getter method.
Summarize:
By using the Sticky Configured 6 framework, we can easily configure and read the application configuration information in the Java library.In this article, we introduced how to introduce the Sticky Configured 6 framework, create configuration files, create configuration classes, and use configuration classes in other classes to read the configuration value.I hope this article can help you better understand and use the Sticky Configured 6 framework.
