使用maven打包jar后 执行jar包问题，Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefi

    本人第一次发帖写的不是很好。希望大家体谅体谅。。。
最近研究maven，然后用maven管理项目，打包项目后发现执行就报错，上网差了很久终于解决了。
废话不多说了，看下面。
很多人使用maven打包后执行jar出现一个错误；

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/context]

在打包时后面的会把前面的覆盖，使得这两个文件中永远只保存最后一个spring依赖的schema和handler。

主要把这两个加上就没问题了

	META-INF/spring.handlers


META-INF/spring.schemas

这是maven的shade打包

	org.apache.maven.plugins
	maven-shade-plugin
	 1.7.1
	
		
			package
			
				shade
			
			
				
					
						META-INF/spring.handlers
					
					
						META-INF/spring.schemas
					
					
						com.chenzhou.test.Main
					
				
			
		
	

 这是maven的assemby打包

        
           

            
                org.apache.maven.plugins
                maven-shade-plugin
                2.1
                
                    
                        package
                        
                            shade
                        
                        
                            
                                
                                    META-INF/spring.handlers
                                
                                
                                    META-INF/spring.schemas
                                
                            
                        
                    
                
            
        
    

然后重新打包 mvn package就没问题了。
