code如下：

public class ServiceAImpl implements ServiceA{
    public void function01(...){
        ...
        this.function02(...);
    }
    ...
    public void function02(...){
        doSomeThing;
    }
}

Spring AOP無法攔截代理內部方法呼叫，若想對function02（）方法做切面，則可以在內部呼叫時重新獲得代理物件實現攔截，步驟如下：

• step 1:寫一個工具類SpringContextUtil實現ApplicationContextAware介面

@Component
public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException{
        SpringContextUtil.applicationContext = applicationContext;
    }

    public
 
 static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static <T> T getBeanByName(String name) {
        return (T) applicationContext.getBean(name);
    }

    public static <T> T getBeanByClass(Class clazz) {
        return (T) applicationContext.getBean(clazz);
    }
}
 

• step 2:在Spring Boot啟動的時候將ApplicationContext注入SpringContextUtil

public class AuthServiceApplication {

    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(AuthServiceApplication.class, args);
        //SpringContextUtil類已設定了靜態的構造方法，此時可以不需要再次注入
        //SpringContextUtil springContextUtil = new SpringContextUtil();
        //springContextUtil.setApplicationContext(applicationContext);
    }
}

• step 3:在內部呼叫時重新獲得代理物件

public class ServiceAImpl implements ServiceA{
    ServiceAImpl serviceA;
    public void function01(...){
        ...
        serviceA = SpringContextUtil.getBeanByClass(this.getClass());
        serviceA.function02(...);
    }
    ...
    public void function02(...){
        doSomeThing;
    }
}
