cvc-elt.1: Cannot find the declaration of element 'beans'

@(编程)

现象描述

导入的一个eclipse项目报错,各种方法都无法解决,报错信息如下:

cvc-elt.1: Cannot find the declaration of element 'beans'

报错文件是applicationContext-ehcache.xml

原因分析

是因为引用的spring包与声明的头文件版本号不一致,改成一致就好了。

解决方法

原来的头文件声明是:

<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd"
default-autowire="byName" default-lazy-init="false">

查看引用jar文件,spring-core是3.2.9的版本,因此修改如下:

<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.2.xsd"
default-autowire="byName" default-lazy-init="false">

去以下三个地址查了一下:

http://www.springframework.org/schema/beans/
http://www.springframework.org/schema/context/
http://www.springframework.org/schema/cache/

仍然不行

按照以上步骤修改之后,仍然报错,即使clean在compile也出错。

修改以上内容变成最简单,eclipse不再报错,然后再改回来。最简单的版本如下:

<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:cache="http://www.springframework.org/schema/cache"
