Use the Fluent Reflection Parent framework to call the method in the Java library

Use the Fluent Reflection Parent framework to call the method in the Java library In Java development, the method of calling the class library is often called during runtime.However, the standard reflex API has some tedious and lengthy problems during use.To make the method call and operating library more conveniently, we can use Fluent Reflection Parent framework. FLUENT Reflection Parent is an open source Java library that encapsulates standard reflex APIs by providing more concise API, so that we can use a reflex mechanism in a smoother way.Its design goal is to provide a more easy -to -use and easy -to -understand way to call the method in the class library, thereby reducing the redundant code. The steps of using Fluent Reflection Parent are as follows: The first step is to import Fluent Reflection Parent library.You can add the following dependencies in the construction file of the project (such as POM.XML): <dependency> <groupId>org.reflections</groupId> <artifactId>reflections</artifactId> <version>0.9.11</version> </dependency> The second step is to obtain an instance of the class to call the method.You can create instances of class in a usual way, or use FLUENT Reflection Parent to scan the class under the specified package and obtain the examples. Reflections reflections = new Reflections("com.example.package"); Set<Class<?>> classes = reflections.getSubTypesOf(Object.class); The third step is to call the API provided by Fluent Reflection Parent.For example, if you want to call a method and get its return value, you can use the `Invokementhod` method of the` Methodinvoker` class: MethodInvoker methodInvoker = new MethodInvoker(); Object result = methodInvoker.invokeMethod(instance, methodName, args); In this method, `Instance` represents an instance of the class. FLUENT Reflection Parent also provides some other useful tools, such as `Fieldaccessor` for operating fields,` classinjector `used to inject classes, and so on.You can choose to use it according to actual needs. It should be noted that using the Fluent Reflection Parent method to call may cause some performance losses because it uses a reflection mechanism at the bottom.Therefore, before use, you should measure its impact on the performance of the project and ensure the necessity of using the scenario. In short, the Fluent Reflection Parent framework provides a more concise and easy -to -understand way to use the reflex mechanism to call.By reducing redundant code, it can help developers perform the operation of Java libraries more efficiently.I hope that through the introduction of this article, you have a deeper understanding of the FLUENT Reflection Parent framework and can use it correctly in actual development.
