Use @Value to assign a value to a static variable in Springboot

Original: Https://www.jianshu.com/p/ea477fc9abf7

For example:

public class Utils {    @Value("${test.host}") private static String host; @Value("${test.port}") private static String port; ......}

It @Value is not possible to assign values directly to static variables, you can use the set method:

@Componentpublic class Utils { private static String host; @Value ("${test.host}") public void sethost(String host) {utils.host = host;} private static String port; @Value ("${test.port}") public void setport(String port) {utils.port = port;} ...} 

Note that you need to use @Component annotations.
