spring boot中static字段用@Value注解不进去解决方案

package com.demo.test.utils;

import java.util.Random;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class ThreadPoolUtil {

private static int corePoolSize;

@SuppressWarnings("static-access")
@Value("${threadpool.corepoolsize}")
public void setCorePoolSize(int corePoolSize) {
this.corePoolSize = corePoolSize;
}

}
