forNameWithThreadContextClassLoader

public static Class<?> forNameWithThreadContextClassLoader(String name)
                                                    throws ClassNotFoundException

已过时。

抛出:

ClassNotFoundException

forNameWithCallerClassLoader

public static Class<?> forNameWithCallerClassLoader(String name,
                                                    Class<?> caller)
                                             throws ClassNotFoundException

已过时。

抛出:

ClassNotFoundException

getCallerClassLoader

public static ClassLoader getCallerClassLoader(Class<?> caller)

已过时。

getClassLoader

public static ClassLoader getClassLoader(Class<?> clazz)

已过时。

get class loader

参数:

clazz -

返回:

class loader

getClassLoader

public static ClassLoader getClassLoader()

已过时。

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 Class<?> forName(String name)
                        throws ClassNotFoundException

已过时。

Same as Class.forName(), except that it works for primitive types.

抛出:

ClassNotFoundException

forName

public static Class<?> forName(String name,
                               ClassLoader classLoader)
                        throws ClassNotFoundException,
                               LinkageError

已过时。

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:

ClassNotFoundException - if the class was not found

LinkageError - if the class file could not be loaded

Class.forName(String, boolean, ClassLoader)

resolvePrimitiveClassName

public static Class<?> resolvePrimitiveClassName(String name)

已过时。

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

isTypeMatch

public static boolean isTypeMatch(Class<?> type,
                                  String value)

We only check boolean value at this moment.

参数:

type -

value -
