public PropertiesLoaderSupport()

方法详细资料

setProperties

public void setProperties(Properties properties)

Set local properties, e.g. via the "props" tag in XML bean definitions. These can be considered defaults, to be overridden by properties loaded from files.

setPropertiesArray

public void setPropertiesArray(Properties... propertiesArray)

Set local properties, e.g. via the "props" tag in XML bean definitions, allowing for merging multiple properties sets into one.

setLocation

public void setLocation(Resource location)

Set a location of a properties file to be loaded.

Can point to a classic properties file or to an XML file that follows JDK 1.5's properties XML format.

setLocations

public void setLocations(Resource... locations)

Set locations of properties files to be loaded.

Can point to classic properties files or to XML files that follow JDK 1.5's properties XML format.

Note: Properties defined in later files will override properties defined earlier files, in case of overlapping keys. Hence, make sure that the most specific files are the last ones in the given list of locations.

setLocalOverride

public void setLocalOverride(boolean localOverride)

Set whether local properties override properties from files.

Default is "false": Properties from files override local defaults. Can be switched to "true" to let local properties override defaults from files.

setIgnoreResourceNotFound

public void setIgnoreResourceNotFound(boolean ignoreResourceNotFound)

Set if failure to find the property resource should be ignored.

"true" is appropriate if the properties file is completely optional. Default is "false".

setFileEncoding

public void setFileEncoding(String encoding)

Set the encoding to use for parsing properties files.

Default is none, using the java.util.Properties default encoding.

Only applies to classic properties files, not to XML files.

mergeProperties

protected Properties mergeProperties()
                              throws IOException

Return a merged Properties instance containing both the loaded properties and properties set on this FactoryBean.

抛出:

IOException

loadProperties

protected void loadProperties(Properties props)
                       throws IOException

Load properties into the given instance.

参数:

props - the Properties instance to load into

抛出:

IOException - in case of I/O errors
