JAVA System 설정값들 모두 가져오기

Properties 설정값을 어떻게 가져올까 고민하다 알게 된정보이다.
JAVA Project 와 관련된 모든값을 가져오는데
Console 에 찍어서 알아보기 쉽게 했다. 앞에 값은 Key 이고 뒤에 값은 Key 해당하는 값이다.

나중에 하나하나를 활용하고 싶을때는  System.getProperty("user.dir");
user.dir 이 Key 되는것이다. 이렇게 해서 값을 꺼내쓸수 있다.

// 모든 시스템정보를 보여준다
Properties props = System.getProperties();
Enumeration enumm = props.keys();
while (enumm.hasMoreElements()) {
    String key = (String) enumm.nextElement();
    String val = (String) props.get(key);
    StringBuffer strBuild = new StringBuffer();
    strBuild.append(key)
           .append(" = ")
           .append(val);
    System.out.println(strBuild.toString());
}
