CatalinaProperties是加载全局配置
该类有一个Properties properties成员
1 从系统变量中看是否有配置文件,如果有的话加载
private static String getConfigUrl() {
return System.getProperty("catalina.config");
}if (configUrl != null) {
is = (new URL(configUrl)).openStream();
}
2.如果系统变量没有配置,查找CatalinaBase()下的conf目录下的catalina.properties,有的话加载
if (is == null) {
try {
File home = new File(getCatalinaBase());
File conf = new File(home, "conf");
File propsFile = new File(conf, "catalina.properties");
is = new FileInputStream(propsFile);
} catch (Throwable t) {
handleThrowable(t);
}
}
3.如果还没有,在/org/apache/catalina/startup下寻找catalina.properties
if (is == null) {
try {
is = CatalinaProperties.class.getResourceAsStream
("/org/apache/catalina/startup/catalina.properties");
} catch (Throwable t) {
handleThrowable(t);
}
}
按照以上顺序寻找配置文件,如果找到就load
properties = new Properties(); properties.load(is);
