关于SpringBoot中事务失效的几种情况

@Transactional
public int update(Admin admin) {
    int update = mapper.update(admin);
    return update;
}
public int invokeUpdate(Admin admin) {
    return update(admin);
}

@Autowired
private AdminService service;
// 然后再调用
public int invokeUpdate(Admin admin) {
    return service.update(admin);
}

((AdminService)ApplicationContext.getBean("adminService")).invokeUpdate(Admin admin);

((AdminService)AopContext.currentProxy()).invokeUpdate(Admin admin);

@Transactional(rollbackFor = Exception.class)
public int update(Admin admin) {
    int update = mapper.update(admin);
    return update;
}

org.springframework.transaction.interceptor.TransactionAspectSupport#invokeWithinTransaction

 try {
     //开启事务
     //这个地方也可以看出是通过代理来实现的事物，如果绕过代理调用（如内部调用），则不会开启事务
     Object var8 = invocation.proceedWithInvocation();
     return var8;
 } catch (Throwable var13) {
     //如果抛出异常，回滚事务
     //如果异常在方法内部被catch了，这个地方就不会接收到异常，就不会回滚事务
     if (txAttr.rollbackOn(var13)) {
         if (var13 instanceof RuntimeException) {
             throw (RuntimeException)var13;
         }
         throw new TransactionAspectSupport.ThrowableHolderException(var13);
     }
     throwableHolder.throwable = var13;
     var9 = null;
 } finally {
     //提交事务
     this.cleanupTransactionInfo(txInfo);
 }
