Spring@value为空[重复]

Question

正如标题所说，my@value不会传递一个值

我在application.properties中编写了以下内容：

project:
  image:
    path= "C:\\Users\\...."

@Component
public class Configuration{
    @Value("${project.image.path}")
    public static String ImagePath;
}

public class Image{
    static File Directory= new File (Configuration.ImagePath);
}

Answer 1

不能在静态属性上使用@value。删除static关键字或为静态变量创建非静态设置器：

@Component
public class Configuration {

    private static String imagePath;

    @Value("${project.image.path}")
    public void setImagePath(String value) {
        this.imagePath = value;
    }
}
