Answer 1

Maven has concept of resource filtering . During build Maven will replace all available placeholders which look like ${some_text} with corresponding properties' values from pom.xml. If no property found then value will not be replaced.

Answer 2

在入口处的loadConfig()中必须是路径config.properties ，该路径在组装后在target/创建。
