获取包下的所有带有指定注解的类 java

1. <dependency>	//导包
       <groupId>org.reflections</groupId>
       <artifactId>reflections</artifactId>
       <version>0.9.11</version>
   </dependency>
   <dependency>
       <groupId>com.google.guava</groupId>
       <artifactId>guava</artifactId>
       <version>21.0</version>
   </dependency>
   

2. 	//反射工具包，指明扫描路径
       Reflections reflections = new Reflections("com.sia.acl.quartz.job");
       
       //获取带JobType注解的类
       Set<Class<?>> jobCLass = reflections.getTypesAnnotatedWith(JobType.class);
   

3. for (Class<?> aClass : jobCLass) {
   		//拿到对应的注解，获取自己想要的信息
           JobType annotation = aClass.getAnnotation(JobType.class);
   }
