@H_301_8@org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema documen
t 'http://www.springframework.org/schema/beans/spring-beans-3.1.xsd',because 1)
could not find the document; 2) the document could not be read; 3) the root ele
ment of the document is not <xsd:schema>.
分析:@H_301_8@
@H_301_8@参考http://www.jb51.cc/article/p-kovsojxe-sp.html@H_301_8@
@H_301_8@这篇文章分析的比较深入,具体原因为:
@H_301_8@根据xx.jar\Meta-INF\spring.schemas文件,先在本地查找相关xsd文件,如果本地没有,则通过网络去获取,实际上上面问题往往出现在没有网络的服务器上@H_301_8@(本地正常,传到服务器上,而服务器一般是不能访问外网的)
但该文章并没有讲清楚更具体的处理措施,只是说了最好用maven的shade打包插件而不是assembly
处理:@H_301_8@
<transformerimplementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>Meta-INF/spring.handlers</resource>
</transformer>
<resource>Meta-INF/spring.schemas</resource>
</transformer>
@H_301_8@才会出现“shade能够将所有jar里的spring.schemas文件进行合并,在最终生成的单一jar包里,spring.schemas包含了所有出现过的版本的集合!”@H_301_8@的效果
