为什么Eclipse不能解析spring-dwr架构？ [英] Why can't Eclipse resolve the spring-dwr schema?
问题描述
Eclipse在我的Spring的applicationContext.xml 中显示以下错误：
Eclipse is showing the following errors in my Spring's applicationContext.xml:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:configuration'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 23 XML Problem
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:controller'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 21 XML Problem
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:remote'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 41 XML Problem
我将鼠标悬停在行项目错误中，它还说：
When I hover my mouse over the line-item error, it also says:
- schema_reference.4: Failed to read schema document 'http://www.directwebremoting.org/
schema/spring-dwr-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>.
我确认根元素实际上是< xsd：schema> 。当我使用自动填充键入< dwr：时，Eclipse正确地显示了各种选项，如< dwr：configuration> ，< dwr：controller> em>等。Eclipse如何知道这一点，而不需要阅读模式？
I confirmed that the root element is in fact <xsd:schema>. When I use autocomplete by typing <dwr: Eclipse correctly shows me the various options like <dwr:configuration>, <dwr:controller>, etc. How can Eclipse know this without reading the schema?
我利用许多不同的命名空间没有问题; DWR架构是唯一没有解决的模式。这是声明：
I make use of many different namespaces without issue; the DWR schema is the only one that isn't being resolved. Here is the declaration:
<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.directwebremoting.org/schema/spring-dwr
http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd"
default-autowire="byName">
我的类路径中有最新的DWR 3.0.0.116.rc1。如果我破解了DWR jar，我发现包含以下内容的META-INF / spring.handlers
I have the latest DWR 3.0.0.116.rc1 in my classpath. If I crack open the DWR jar, I find META-INF/spring.handlers containing:
http\://www.directwebremoting.org/schema/spring-dwr=org.directwebremoting.spring.DwrAnnotationNamespaceHandler
$ b $包含：
and META-INF/spring.schemas containing:
http\://www.directwebremoting.org/schema/spring-dwr-2.0.xsd=org/directwebremoting/spring/spring-dwr-2.0.xsd
http\://www.directwebremoting.org/schema/spring-dwr-3.0.xsd=org/directwebremoting/spring/spring-dwr-3.0.xsd
转义的冒号扔了我一点，但我认为这是正确的，否则每个人的DWR将被打破。
The escaping of the colon threw me off a bit, but I assume it's all correct, otherwise everyone's DWR would be broken.
在我从实时抓取这个特定的模式之前DWR网站，但是当我的制作系统因为DWR网站关闭而崩溃时，我很有帮助。
Before I was grabbing this particular schema in real time from the DWR website, but I got bit by this when my production system crashed because the DWR site was down.
推荐答案
你可以尝试添加用户指定ca talog对Eclipse的贡献。在窗口 - >首选项 - > XML-> XML目录下，选择用户指定条目，然后选择添加按钮。
You could try adding a user specified catalog contribution to Eclipse. Under Window->Preferences->XML->XML Catalog select User Specified Entries and then the Add button.
然后，您可以添加模式的详细信息（您可以在丢弃连接的情况下在本地复制文件）。然后，Eclipse将在验证期间访问模式。
You can then add the details for the schema (you could copy the file locally in case of dropped connection). Eclipse will then have access to the schema during validation.
