Application of Commons Beanutils Core framework in the Java class library

Application of Commons Beanutils Core framework in the Java class library Commons Beanutils Core is an open source framework for handling JavaBean in the Java class library.It provides a series of tools to simplify the operation of JavaBean, including the replication, acquisition and setting attribute values of attributes. JavaBean is a Java class that meets specific specifications. It has private attributes, public Getter and Setter methods, and a non -constructor function.The Beanutils Core framework makes developers easily operate JavaBean. Below is a common application example of some Commons Beanutils Core framework in the Java library: 1. Copy the attribute value Through the Beanutils Core framework, one JavaBean's attribute value can be copied to another JavaBean.For example, suppose we have a Person class and a Persondto class, which have the same attributes. We can use the following code to copy the attribute value of Person to Persondto: Person person = new Person(); person.setName("John"); person.setAge(25); PersonDTO personDTO = new PersonDTO(); BeanUtils.copyProperties(personDTO, person); System.out.println (Persondto.getName ()); // Output "John" System.out.println (Persondto.getage ()); // Output 25 2. Dynamic setting attribute value Through the Beanutils Core framework, the attribute value of JavaBean can be set dynamically.For example, suppose we have a Person class, and we want to set its attribute values dynamically at runtime, we can use the following code: Person person = new Person(); BeanUtils.setProperty(person, "name", "John"); BeanUtils.setProperty(person, "age", "25"); System.out.println (Person.getName ()); // Output "John" System.out.println (Person.getage ()); // Output 25 3. Get the attribute value Through the Beanutils Core framework, the attribute value of JavaBean can be easily obtained.For example, assuming we have a Person object, we want to obtain the value of its name attribute, we can use the following code: Person person = new Person(); person.setName("John"); String name = BeanUtils.getProperty(person, "name"); System.out.println (name); // Output "John" Summarize: Commons Beanutils Core framework provides JavaBean's convenience tools for Java developers.It can help developers easily copy attribute values, dynamically set attribute values, and obtain attribute values.Through this framework, developers can reduce redundant code and improve development efficiency.Whether in the traditional Javaweb project or in modern micro -service architecture, Commons Beanutils Core is a very practical and classic framework. Remarks: When using Commons Beanutils Core, be sure to process the input data carefully to avoid possible security vulnerabilities, such as injecting the code injection problem caused by improperly processing data.
