Use the Commons Beanutils Core framework to convert the Bean in the Java class library
Commons Beanutils Core is a popular Java class library for simplifying the conversion between JavaBean.By providing a set of practical tools and methods, developers can easily convert one JavaBean object into another JavaBean object without manual copy attributes.
Before using the Commons Beanutils Core framework, you need to introduce related jar packages in the project.Once the dependencies are introduced, you can start using it to convert the bean.
Below is a simple example, showing how to use the Commons Beanutils Core framework for the bean conversion:
1. Create two JavaBean classes, which are SourceBean and targetBean, which have similar attributes.
public class SourceBean {
private String name;
private int age;
// getters and setters
}
public class TargetBean {
private String name;
private int age;
// getters and setters
}
2. Use the Commons Beanutils Core framework in the code to convert the bean.First, you need to create a Beanutils object.
import org.apache.commons.beanutils.BeanUtils;
public class BeanConverter {
public static void main(String[] args) {
SourceBean source = new SourceBean();
source.setName("John");
source.setAge(25);
TargetBean target = new TargetBean();
try {
BeanUtils.copyProperties(target, source);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Source Bean: " + source.getName() + ", " + source.getAge());
System.out.println("Target Bean: " + target.getName() + ", " + target.getAge());
}
}
3. Run the above code, and the output will be the following results:
Source Bean: John, 25
Target Bean: John, 25
By using the Commons Beanutils Core framework, we can easily copy the attribute of one JavaBean object to another JavaBean object.This greatly simplifies the conversion process between Bean and reduces the workload of manual replication attributes.
To sum up, the Commons Beanutils Core framework is a powerful and easy -to -use Java class library that can be used to simplify the conversion between JavaBean.Whether in application development or testing, it can improve the efficiency of developers.I hope this article will help you!
