public String hi() { return "hi2"; } } 此时没指定具体的接口实现类，spring会报错，但是只要将Hi2改成 @Service @Primary...Hi2 implements Hi{ @Override public String hi() { return "hi2"; } } 命令行就会输出 hi2 @Primary...就是默认的意思，而他的使用情况当然不是用于service层了，而是在造轮子的时候，往往一个基本接口类有多次实现，我们只要给其中一个实现加上@Primary，那么在使用这个接口类的时候就不用每次都@Qualifier

作为正常人只能先去看一下是否可以删除其中一个jar包，发现这条路是走不通的只能去排除其中一个Bean了 这个就要讲到今天要说的两个注解了 @Qualifier 和 @Primary @qualifiel...@Primary Indicates that a bean should be given preference when multiple candidates are qualified to autowire...If exactly one ‘primary’ bean exists among the candidates, it will be the autowired value....This annotation is semantically equivalent to the {@code} element’s {@code primary} attribute 不难看出如果用...primary注解其中一个bean就要优先于其他的Bean，当然这个对于这种三方jar包最好不要添加的，谁知道它会不会后期又出什么幺蛾子，只能改自己的代码了最后的方案是改成@qualifiel（“getMetricRegistry
