This article mainly introduces springboot can not reference non-static variables from the static context of how to solve the relevant knowledge, the content is detailed and easy to understand, simple and fast operation, with a certain reference value, I believe that after reading this springboot can not reference non-static variables from the static context of how to solve the article will have a harvest, let's take a look.

Static methods can be called without creating an object, and non-static methods can only be called with an instance of the object.

Therefore, it is impossible to reference a non-static method directly in a static method, because the compiler cannot give the answer without knowing which object's non-static method to call, because there are no objects.

Java is afraid of not finding someone.

Solution:

Spring's set injection method, which injects static variables through a non-static setter method, as shown below

@ PropertySource (value = {"classpath:config/application.yml"}, ignoreResourceNotFound = true,encoding= "UTF-8") @ Service public class tank_task {private static String kafka; public static String getProfilesKafka () {return kafka;} @ Value ("${stream.kafka.servers}") public void setProfilesKafka (String kafka) {tank_task.kafka = kafka } public static void tank_test () {System.out.println ("config static kafka:" + tank_task.getProfilesKafka ());}} on "how to solve the problem that springboot cannot reference non-static variables from a static context".
