nullSafeToString

public static String nullSafeToString(Class<?> clazz)

Get the fully qualified name of the supplied class.

This is a null-safe variant of Class.getName().

参数:

clazz - the class whose name should be retrieved, potentially null

返回:

the fully qualified class name or "null" if the supplied class reference is null

nullSafeToString

public static String nullSafeToString(Class<?>... classes)

Generate a comma-separated list of fully qualified class names for the supplied classes.

参数:

classes - the classes whose names should be included in the generated string

返回:

a comma-separated list of fully qualified class names, or an empty string if the supplied class array is null or empty

nullSafeToString

public static String nullSafeToString(Function<? super Class<?>,? extends String> mapper,
                                      Class<?>... classes)

Generate a comma-separated list of mapped values for the supplied classes.

The values are generated by the supplied mapper (e.g., Class::getName, Class::getSimpleName, etc.), unless a class reference is null in which case it will be mapped to "null".

参数:

mapper - the mapper to use; never null

classes - the classes to map

返回:

a comma-separated list of mapped values, or an empty string if the supplied class array is null or empty

getClassLoader

public static ClassLoader 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)

getClassLoader

public static ClassLoader getClassLoader(Class<?> clazz)

get class loader

参数:

clazz -

返回:

class loader
