Edit Jar file with xml or properties file in Java

Question

I have an own .jar file with some configuration about OAuth2 and Spring security Server. Now I want to edit file .xml in it to suitable with my project (like url, value, name). So do we have any way to do it.

Thanks.

Answer 1

An option is to externalize your properties into a property file, web container (tomcat, jboss)enviroment variables or SO enviroment variables.

Then you need to tell Spring where your properties are located

@Configuration
@PropertySource("file:${app.home}/app.properties")
public class AppConfig {
    @Autowired
    Environment env;
}

Here there are some tutorials
