spring打包到jar包的问题解决
今天把spring打包到一个jar包中，jar运行时抛异常

查看spring文件
没有问题，
可以连接外网访问到http://www.springframework.org/schema/beans/spring-beans-4.3.xsd可以正常运行，在项目中也正常运行，就是打包为jar时，放到服务器上，不能直接连外网时才出现问题。
排查spring.schemas文件，发现jar包中META-INF\spring.schemas文件内容缺失，应该是打包时造成的
解开jar包，找到spring.schemas文件，添加：
http\://www.springframework.org/schema/beans/spring-beans-2.0.xsd=org/springframework/beans/factory/xml/spring-beans-2.0.xsd http\://www.springframework.org/schema/beans/spring-beans-2.5.xsd=org/springframework/beans/factory/xml/spring-beans-2.5.xsd http\://www.springframework.org/schema/beans/spring-beans-3.0.xsd=org/springframework/beans/factory/xml/spring-beans-3.0.xsd http\://www.springframework.org/schema/beans/spring-beans-3.1.xsd=org/springframework/beans/factory/xml/spring-beans-3.1.xsd http\://www.springframework.org/schema/beans/spring-beans-3.2.xsd=org/springframework/beans/factory/xml/spring-beans-3.2.xsd http\://www.springframework.org/schema/beans/spring-beans-4.0.xsd=org/springframework/beans/factory/xml/spring-beans-4.0.xsd http\://www.springframework.org/schema/beans/spring-beans-4.1.xsd=org/springframework/beans/factory/xml/spring-beans-4.1.xsd http\://www.springframework.org/schema/beans/spring-beans-4.2.xsd=org/springframework/beans/factory/xml/spring-beans-4.2.xsd http\://www.springframework.org/schema/beans/spring-beans-4.3.xsd=org/springframework/beans/factory/xml/spring-beans-4.3.xsd http\://www.springframework.org/schema/beans/spring-beans.xsd=org/springframework/beans/factory/xml/spring-beans-4.3.xsd
问题解决。
原因：
使用maven-assembly-plugin打包，由于spring多个jar包中都包含spring.schemas，而assembly只会把第一次遇到的schemas文件打入jar包。
放弃assembly，使用shade把包，指定schemas文件append方式添加进来。
org.apache.maven.plugins maven-shade-plugin 1.7 package shade true jar-with-dependencies META-INF/spring.handlers META-INF/spring.schemas META-INF/spring.tooling
