Java read. properties file

In the Web development process, some configuration to be saved to the properties file, this chapter will give a tool class for easy to read the properties file.

Case:

1:config.properties file

Name=\u843d\u82b1\u6709\u610fstr=\u6d41\u6c34\u65e0\u60c5

2:propertiesutil class
