今天使用ApplicationContextAware写了一个工具类 用来获取bean 时报错，错误在最下面。
[code=java]
package com.zdmoney.riskmgt.ruleEngine.reflect; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; /** * @author zhangc * @since 2018/7/18 18:02 **/ @Component public class SpringContextUtils implements ApplicationContextAware { private static ApplicationContext context; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { context = applicationContext; } public static <T> T getBeanByClass(Class<T> c){ return context.getBean(c); } public static Object getBeanByName(String name){ return context.getBean(name); } }

我使用 SpringContextUtils.getBeanByClass(ZaService.class) 报如下错误， 但是用 IZaService.class 正常获取到（IZaService是ZaService的接口。本问题中的 I 开头的都是相应的 接口类。。）
我的排错过程
1. 于是我尝试使用 SpringContextUtils.getBeanByName("zaService") 也是正常的。。
2. 我尝试使用 SpringContextUtils.getBeanByClass(RiskService.class) 正常
SpringContextUtils.getBeanByClass(IRiskService.class) 正常
3. 于是我比较 ZaService 和 RiskService 和相应接口， 都是普通的service 和接口啊。没什么本质区别啊
4. 我把ZaService 中的 方法清空。再次尝试 SpringContextUtils.getBeanByClass(ZaService.class)竟然可以获取了。。
5. 可能是代码中有什么影响了spring容器。。 最后发现是 一个注解造成的 ，， 去掉该注解则可以正常获取bean
[code=java]@Override
@ExternalDsAccess(partner = DataSourcePartner.ZA,source = DataSourceEnum.ZA_SJSM)
public RiskResultDto<String> checkThreeElements(Map<String,Object> param) {
[/code]
该注解是一个切面的注解 保存操作日志使用的 。
[code=java]
@Pointcut("@annotation(com.zdmoney.riskmgt.component.aspect.ExternalDsAccess)")
public void dataSourceProcess() {
}
@AfterReturning(pointcut = "dataSourceProcess()", returning = "object")
public void afterProcess(JoinPoint joinPoint, Object object) {
[/code]
有人遇到这种情况吗 ，，求解救。？？？？？？？？？？？？？？？？？？？？？？？？？？？？？
