public class WebAppClassLoader
extends URLClassLoader

ClassLoader for HttpContext. Specializes URLClassLoader with some utility and file mapping methods. This loader defaults to the 2.3 servlet spec behavior where non system classes are loaded from the classpath in preference to the parent loader. Java2 compliant loading, where the parent loader always has priority, can be selected with the WebAppContext.setParentLoaderPriority(boolean) method and influenced with WebAppContext.isServerClass(String) and WebAppContext.isSystemClass(String). If no parent class loader is provided, then the current thread context classloader will be used. If that is null then the classloader that loaded this class is used as the parent.

Constructor.

抛出：

IOException

方法详细信息

getName

public String getName()

返回：

the name of the classloader

setName

public void setName(String name)

参数：

name - the name of the classloader

getContext

public WebAppClassLoader.Context getContext()

addClassPath

public void addClassPath(Resource resource)
                  throws IOException

参数：

resource - Comma or semicolon separated path of filenames or URLs pointing to directories or jar files. Directories should end with '/'.

抛出：

IOException
