It allows reading Properties files from the classpath or resource file. It uses ClassLoader.getResourceAsStream to find a properties file, so that means it either has to be on the classpath or bundled into the jar. <P> It is intended that you only pass a single string to find the properties like "foo". That will cause Props to search for a file called foo.properties. The directory it searches in will be by default the "res/" directory. That means that it will search your classpath or jar file for a file res/foo.properties. If you run your software in different environments you can pass a system property to the java virtual machine called "environment". In that case the searching will descend another directory level. e.g. if you pass -Denvironment=development, then it will first look for a file res/development/foo.properties. If you are using servlets your servlet engine should have a means to pass in system variables. <P> This makes it easy to integrate properties into your code. All you do is use Props to find a certain class of property, like "foo" and it will take care of where to physically find the file. And you can set up different properties for different environments. <P> TODO: make it combine the environment and non-environment specific properties into the one set.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../serialized-form.html" TARGET="javatools.util.Props">Serialized Form</A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR></TABLE> <A NAME="fields_inherited_from_class_java.util.Properties"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class java.util.Properties</B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>defaults</CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#getFullName()">getFullName</A></B>()</CODE><BR> Returns the full name for this Props.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#getLocalConfigDir()">getLocalConfigDir</A></B>()</CODE><BR> Returns the local configuration directory.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#load()">load</A></B>()</CODE><BR> Loads properties.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#loadLocalConfig()">loadLocalConfig</A></B>()</CODE><BR> Loads local configuration file.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#loadResources()">loadResources</A></B>()</CODE><BR> Loads resources (aka properties).</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#reset()">reset</A></B>()</CODE><BR> Resets all this Props.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../javatools/util/Props.html">Props</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#singleton(java.lang.String)">singleton</A></B>(java.lang.String name)</CODE><BR> Returns a brand new Props object referencing properties of the given name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javatools/util/Props.html#store()">store</A></B>()</CODE><BR> Stores properties in a file.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.util.Properties"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.util.Properties</B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>getProperty, getProperty, list, list, load, propertyNames, save, setProperty, store</CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.util.Hashtable"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from class java.util.Hashtable</B></TD></TR>⌨️ 快捷键说明
