AOP失效的情况与解决，分布式锁，客户端的熔断降级

AOP的失效情况通常是因为事务类自己调用导致被AOP代理的方法没有实现接口导致。
客户端的熔断降级可以通过@SentinelResource(value = "getAddressBookDetail", fallback = "detailFallback", blockHandler = "detailBlockHandler")这种注解实现。
不过也因此，openfien的调用需要再包装一层
package com.jzo2o.orders.manager.service.client;

import com.alibaba.csp.sentinel.annotation.SentinelResource;
import com.alibaba.csp.sentinel.slots.block.BlockException;
import com.jzo2o.api.customer.AddressApi;
import com.jzo2o.api.customer.dto.response.AddressBookResDTO;
import com.jzo2o.orders.manager.service.impl.OrdersCreateServiceImpl;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**

  @Component

  public class CustomerClient {

  @Resource
  private AddressApi addressApi;

  @SentinelResource(value = "getAddressBookDetail", fallback = "detailFallback", blockHandler = "detailBlockHandler")
  public AddressBookResDTO detail(Long id) {
  log.error("根据id查询地址簿，id:{}", id);
  // 调用其他微服务方法
  AddressBookResDTO detail = addressApi.detail(id);
  return detail;
  }

  //执行异常走
  public AddressBookResDTO detailFallback(Long id, Throwable throwable) {
  log.error("非限流、熔断等导致的异常执行的降级方法，id:{},throwable:", id, throwable);
  return null;
  }

  //熔断后的降级逻辑
  public AddressBookResDTO detailBlockHandler(Long id, BlockException blockException) {
  log.error("触发限流、熔断时执行的降级方法，id:{},blockException:", id, blockException);
  return null;
  }
  }

分布式事务锁可以通过redission实现
