使用jersey+spring构建RESTful服务，并将应用部署在不能连接外网的服务器上。部署时，报错信息如下，

WARNING: Ignored XML validation warning 
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document ‘http://www.springframework.org/schema/aop/spring-aop-3.0.xsd‘, because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

也就是，找不到如下的元素的声明

<aop:aspectj-autoproxy />

解决：

通过去除spring配置文件中schemaLocation的版本号（如2.0，3.0），让spring自己匹配版本。通常情况下，都是因为所依赖的spring版本号低于配置文件中指定的版本号。修改后如下

<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:context="http://www.springframework.org/schema/context" 
       xmlns:aop="http://www.springframework.org/schema/aop" 
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context.xsd 
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop.xsd">

如果希望保留spring配置文件中的schema版本号，而所依赖spring版本号不小于配置文件对应版本号，那么问题很有可能出在依赖其他库时没有去除这些库对于spring的依赖（通常它们会依赖于低版本的spring，从而导致整个项目的spring版本出问题）。可以通过在pom.xml中，对于这些库，剔除spring依赖。例如我使用的jersey-spring，则修改pom.xml后如下，
