NoUniqueBeanDefinitionException: No qualifying bean of type ‘XXXX‘ available: expected single matchi

spring在进行注入的时候如果发现有两个bean，这时候他是不知道注入哪个bean的，就会报如下的错误：

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'XXXX' available: expected single matching bean but found 2:

这时候可以在bean的xml文件里给bean配置优先级：

<bean id="hotGenericSearchPartyHandler" class="com.exigen.hot.billing.ui.HotGenericSearchPartyHandler" scope="prototype" primary="true">
</bean>

里面主要就是 primary这个，如果想让这个bean优先被设置的话，就可以加上这个配置

出现这种情况的case：

在运行时创建bean，而不是在spring启动的时候创建的：

ApplicationContext context;
Handler handler = new Handler();
context.getAutowireCapableBeanFactory().autowireBean(handler);

比如在一个类里面有一个接口的引用，但是实现这个接口的类有多个，而且都放到了spring容器中，那在注入的时候，他不知道注入哪一个，所以可以通过设置bean的优先级来决定在有多个bean的时候选择注入哪个
