解决spring aop无法拦截代理内部函数调用的问题

code如下：

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

Spring AOP无法拦截代理内部方法调用，若想对function02（）方法做切面，则可以在内部调用时重新获得代理对象实现拦截，步骤如下：

• step 1:写一个工具类SpringContextUtil实现ApplicationContextAware接口

@Component
public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

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

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

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

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

• step 2:在Spring Boot启动的时候将ApplicationContext注入SpringContextUtil

public class AuthServiceApplication {

    public static void main(String[] args) {
        ApplicationContext applicationContext = (, args);
        //SpringContextUtil类已设置了静态的构造方法，此时可以不需要再次注入
        //SpringContextUtil springContextUtil = new SpringContextUtil();
        //(applicationContext);
    }
}

• step 3:在内部调用时重新获得代理对象

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