        参数:
        cls -
        返回:
        class loader

      • getClassLoader

        public static  getClassLoader()
        Return the default ClassLoader to use: typically the thread context ClassLoader, if available; the ClassLoader that loaded the ClassUtils class will be used as fallback.

        Call this method if you intend to use the thread context ClassLoader in a scenario where you absolutely need a non-null ClassLoader reference: for example, for class path resource loading (but not necessarily for Class.forName, which accepts a null ClassLoader reference as well).

        返回:
        the default ClassLoader (never null)

      • forName

        public static <?> forName​( name,
                                classLoader)
                        throws ,
        Replacement for Class.forName() that also returns Class instances for primitives (like "int") and array class names (like "String[]").
        参数:
        name - the name of the Class
        classLoader - the class loader to use (may be null, which indicates the default class loader)
        返回:
        Class instance for the supplied name
        抛出:
        - if the class was not found
        - if the class file could not be loaded

      • resolvePrimitiveClassName

        public static <?> resolvePrimitiveClassName​( name)
        Resolve the given class name as primitive class, if appropriate, according to the JVM's naming rules for primitive classes.

        Also supports the JVM's internal class names for primitive arrays. Does not support the "[]" suffix notation for primitive arrays; this is only supported by forName(java.lang.String).

        参数:
        name - the name of the potentially primitive class
        返回:
        the primitive class, or null if the name does not denote a primitive class or primitive array class
