我正在阅读关于DefaultMessageListenerContainer的 spring文档
它说:"注意:不要将Spring的CachingConnectionFactory与动态扩展结合使用.理想情况下,根本不要将它与消息监听器容器一起使用,因为通常最好让监听器容器本身在其生命周期内处理适当的缓存.此外,停止和重新启动侦听器容器只能使用独立的本地缓存连接 - 而不能使用外部缓存连接."
谁有人解释原因？
我正在将我的应用程序从java 1.6升级到1.7.当我尝试使用Maven 3.2.1进行构建时,我的构建失败并出现以下错误消息:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project my-app5: Compilation failure: Compilation failure:
[ERROR] could not parse error message: warning: [options] bootstrap class path not set in conjunction with -source 1.6
我正在使用java 1.7热点,之前我使用的是1.6 jrockit.我的应用程序是多模块,很少有模块像往常一样编译和构建,这个模块失败了.
我已正确设置java home并且mvn --version显示在输出下方:

我有一个用@Transactional 和另一个自定义注释@Custom 注释的方法。此自定义注释包含在建议中。操作顺序如下：
1.Transactional method gets called
2.Sees @Transactional and @Custom
3.As @Custom is intercepted by around advice, it first executes code before invocation of method
4.invocationContext.proceed()
5.Transaction gets created
6.Actual method runs
7.Back to around advice and executes code after method invocation
我想在调用建议之前创建事务。像下面这样：
1.Transactional method gets called
2.Sees @Transactional and @Custom
3.Transaction gets created (propagate this transaction to @Custom)
4.As @Custom is intercepted by around advice, it first executes code before invocation of method
5.invocationContext.proceed()
6.Actual method runs
7.Back …在我的应用程序中运行集成测试时，我在我的集成测试之一的故障安全测试报告中收到以下错误消息：
