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,
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-spring</artifactId>
<version>1.17.1</version>
<exclusions>
<exclusion>
