Spring Dependency Injection入JPA实体监听器

问题描述

我需要将一个Spring依赖注入到JPA实体监听器中。我知道我可以使用@Configurable和Spring的AspectJ weaver作为javaagent解决这个问题，但这似乎是一个hacky解决方案。有没有其他方法可以完成我想要做的事情？

推荐答案

另一个技巧是使用静态实现一个实用程序类帮助您在任何地方使用Spring bean的方法，不仅仅是在托管类中：

Another trick is to implement an utility class with static method that helps you to use Spring beans everywhere, not only in managed classes:

@Component
public final class BeanUtil {

    private static ApplicationContext context;

    private BeanUtil(ApplicationContext context) {
        BeanUtil.context = context;
    }

    public static <T> T getBean(Class<T> clazz) throws BeansException {

        Assert.state(context != null, "Spring context in the BeanUtil is not been initialized yet!");
        return context.getBean(clazz);
    }
}
