Method Detail

registerMaskedPropertyName

public static void registerMaskedPropertyName(String name)

Register a property name for masking. This will prevent certain values from leaking e.g. into debugging output or logfiles.

Parameters:

name - the key of the property to be masked.

Throws:

IllegalArgumentException - is name is null or empty.

maskedPropertyValue

public static String maskedPropertyValue(Map.Entry<?,?> property)

Returns the String representation of the property value or a masked String if the property key has been registered previously via registerMaskedPropertyName(String).

Parameters:

property - a key/value pair

Returns:

String of the property value or a "masked" String that hides the contents, or null if the property, its key or its value is null.

loadProperties

public static Properties loadProperties(String fileName,
                                        Class<?> callingClass)
                                 throws IOException

Read in the properties from a properties file. The file may be on the file system or the classpath.

Parameters:

fileName - - The name of the properties file

callingClass - - The Class which is calling this method. This is used to determine the classpath.

Returns:

a java.util.Properties object containing the properties.

Throws:

IOException

loadProperties

public static Properties loadProperties(URL url)
                                 throws IOException

Throws:

IOException

loadAllProperties

public static Properties loadAllProperties(String fileName,
                                           ClassLoader classLoader)

Load all properties files in the classpath with the given properties file name.

loadProperties

public static Properties loadProperties(InputStream is)
                                 throws IOException

Throws:

IOException

removeXmlNamespacePrefix

                                           Map newProps)

Will create a map of properties where the names have a prefix Allows the callee to supply the target map so a comparator can be set

Parameters:

props - the source set of properties

prefix - the prefix to filter on

newProps - return map containing the filtered list of properties or an empty map if no properties matched the prefix

getPropertiesWithoutPrefix
