拦截器

package com.example.interceptor;
    
    import org.aopalliance.intercept.MethodInterceptor;
    import org.aopalliance.intercept.MethodInvocation;

     */
    public class MyMethodInterceptor implements MethodInterceptor{
        @Override
        public Object invoke(MethodInvocation methodInvocation) throws Throwable {
            System.out.println("调用方法前调用");
            Object o = methodInvocation.proceed();
            System.out.println("调用方法后调用");
            return o;
        }
    }

    @Configuration
    public class AppConfig {
