Question

这是关于java项目中的xml文件的问题。我有一个spring 4项目，可以从这里下载 - http://www.perfmath.com/spring/soba_zip/soba4_download_1.zip

在src＆gt;下主要＆gt; webapp＆gt; web-inf＆gt; lib，soba-webflow.xml文件给了我很多错误。我用Google搜索并看到类似的错误，但我没有找到一种方法来纠正它。请帮忙。

错误1 -

Multiple annotations found at this line:
    - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'webflow:flow-registry'.
    - schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.4.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>.

错误2 -

cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'webflow:flow-executor'.

xml文件中的代码段 -

Answer 1

我下载了soba4_download_1.zip并观察到在pom.xml元素中你引用的是2.3.3版本的webflow：

    <spring.webflow.version>2.3.3.RELEASE</spring.webflow.version>

但是在你的soba-webflow.xml中，你指的是spring-webflow-config-2.4.xsd的模式位置。

要解决此问题，您有两个选择：

选项1：

由于您已拥有2.3.3 webflow版本，请将spring-webflow-config架构位置更改为：

    http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd

选项2：

升级到webflow 2.4版本。在spring-webflow-2.4.0.RC1.jar中，您包含了spring-webflow-config-2.4.xsd文件。

Answer 2

如果从IDE中收到这些错误，请确保可以从中访问架构文档http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd（网络连接，代理设置等）。我可以在Eclipse中成功加载XML。
