1：没有在Spring Scan扫描器中加入该类的包名，就是用注解，相从Spring容器中获取service实例(@Resource注解想从Spring容器中注入实例，不好意思，人家Spring更本没给你分配资源)

2：在Spring中扫描器加入该包，没有在该类体上加（@Component）注解，就想用@Resource取出service实例，不好意思人家Spring根本没找到说的这个类

3：如果你懒得配这些配置文件，我敢说你是一名出色的程序员-懒，解决方法也是有的，像类中这样

ApplicationContext context = (ApplicationContext)se.getSession().getServletContext().getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
ManagerLoginLogService managerLoginLogService = context.getBean(“managerLoginLogService”,ManagerLoginLogService.class);

什么扫描什么装配，都是浮云，我们自己去上下文对象中 ApplicationContext context 去取拥有资源的Spring容器中取就行了，取出service了，这个问题也能解决

//下面内容为本人修改问题原因：

在Tomcat配置文件service.xml中

<Resource name="jdbc/mqService"

上述name名称重复，导致以上问题的出现，注释掉不用的，或者删除即可
