Twitter Storm使用笔记

1、发布storm程序需要使用到Maven Assembly plugin. 如果项目中有引用spring的多个包一起使用，那么就会在打包的后丢失部分jar,表现如下：

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/p]

其原因是：

The issue is that, to make the application work outside Eclipse, we use the Maven Assembly plugin. It expands all the dependent JARs into the final JAR. This means it cannot put several files with the same name in the package and it has to choose one of the spring.handlers files.

解决方式：

再添加plugin:[code]
org.apache.maven.plugins
maven-shade-plugin


package

shade




at.seresunit.lecturemanager_connector.App


META-INF/spring.handlers


META-INF/spring.schemas





[/code]且在resources下面添加文件夹：

META-INF

spring.handlers

spring.schemas

spring.handlers内容：[code]http\://www.springframework.org/schema/p=org.springframework.beans.factory.xml.SimplePropertyNamespaceHandler
http\://www.springframework.org/schema/util=org.springframework.beans.factory.xml.UtilNamespaceHandler
http\://www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler

http\://www.springframework.org/schema/jee=org.springframework.ejb.config.JeeNamespaceHandler
http\://www.springframework.org/schema/lang=org.springframework.scripting.config.LangNamespaceHandler[/code]spring.schemas内容：[code]http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
