Loading a class dynamically is easy. All you need to do is to obtain aClassLoaderand call itsloadClass()method. Here is an example: public class MainClass { public static void main(String[] args){ ClassLoader classLoader = MainClass.class.getClassLoader(); try { Class aClass = classLo...
Applications implement subclasses of ClassLoader in order to extend the manner in which the Java virtual machine dynamically loads classes. Class loaders may typically be used by security managers to indicate security domains. In addition to loading classes, a class loader is also responsible for loc...

Applications implement subclasses ofClassLoaderin order to extend the manner in which the Java virtual machine dynamically loads classes. Class loaders may typically be used by security managers to indicate security domains. TheClassLoaderclass uses a delegation model to search for classes and resources...
Applications implement subclasses ofClassLoaderin order to extend the manner in which the Java virtual machine dynamically loads classes. 实现了ClassLoader的子类的应用是为了扩展JVM动态加载类的方式. Class loaders may typically be used by security managers to indicate securitydomains. ...
这就是因为ServiceLoader.load(Search.class)在加载某接口时,会去META-INF/services下找接口的全限定名文件,再根据里面的内容加载相应的实现类。 这就是spi的思想,接口的实现由provider实现,provider只用在提交的jar包里的META-INF/services下根据平台定义的接口新建文件,并添加进相应的实现类内容就好。
ClassLoader是Java的类加载器,用于把class文件加载到JVM中,下面大概了解一下Java类加载器的概况。 一,java提供的加载器 Java提供了三个ClassLoader: 1,BootstrapClassLoader 用于加载JAVA核心类库,也就是环境变量的%JRE_HOME%\lib下的rt.jar、resources.jar、charsets.jar等。
The Java Virtual Machine dynamically loads, links and initializes classes and interfaces. Loading is the process of finding the binary representation of a class or interface type with a particular name and creating a class or interface from that binary representation. Linking is the process of taki...
1. Introduction to Class Loaders Class loaders are responsible forloading Java classes dynamically to the JVM(Java Virtual Machine) during runtime.They’re also part of the JRE (Java Runtime Environment). Therefore, the JVM doesn’t need to know about the underlying files or file systems in ...
( 1)Class loadClass(String name, boolean resolve) 使用指定 二进 制名称加载类 ,name 指定以包表示法表示 的二进制类 的名称。 (2) Class defi neClass(String name,byte口 b,int of ,int len) 将 byte 数组转换为 Class 类的实例 ,并分析 Class 。 (3) fi ndClass (Stri ng name) 使用指...
