BeanIsAbstractException错误解决
???? 今天开始学习joindesk，按照手册中的Joindesk Setup运行，启动服务器，就出现BeanIsAbstractException异常，异常代码如下：
?
org.springframework.beans.factory.BeanIsAbstractException: Error creating bean with name 'baseTxService': Bean definition is abstractat org.springframework.beans.factory.support.AbstractBeanFactory.checkMergedBeanDefinition(AbstractBeanFactory.java:1035)at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:244)at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:160)at org.springframework.beans.factory.support.AbstractBeanFactory.isSingleton(AbstractBeanFactory.java:358)at org.springframework.context.support.AbstractApplicationContext.isSingleton(AbstractApplicationContext.java:745)at net.joindesk.app.SpringWebApp.init(SpringWebApp.java:83)at net.joindesk.app.WebAppLoader.contextInitialized(WebAppLoader.java:71)at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3843)at org.apache.catalina.core.StandardContext.start(StandardContext.java:4342)at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045)at org.apache.catalina.core.StandardHost.start(StandardHost.java:719)at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045)at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443)at org.apache.catalina.core.StandardService.start(StandardService.java:516)at org.apache.catalina.core.StandardServer.start(StandardServer.java:710)at org.apache.catalina.startup.Catalina.start(Catalina.java:578)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)at java.lang.reflect.Method.invoke(Method.java:597)at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288)at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)
????? 搞了半天，还是通过debug，查看源代码后才知道错误原因，后来在baseTxService后面加上scope="prototype"才把问题解决。
????? 现在把正确代码写下，以供大家参考，希望能够帮助大家。
