[转载]The content of element type "struts-config" must match

 完全解决struts启动时报错:The content of element type "struts-config" must match "(data-sources?,form-beans?,global-exceptions?,global-forwards?,action-mappings?,controller?,message-resources* 

最近新建一个项目,发现tomcat启动的时候时,控制台一直报告异常信息:

10 12 22 09:49:016,306  ERROR Digester:1463 - Parse Error at line 21 column 17: The content of element type "struts-config" must match "(data-sources?,form-beans?,global-exceptions?,global-forwards?,action-mappings?,controller?,message-resources*,plug-in*)".
org.xml.sax.SAXParseException: The content of element type "struts-config" must match "(data-sources?,form-beans?,global-exceptions?,global-forwards?,action-mappings?,controller?,message-resources*,plug-in*)".
。。。。。。

虽然这不影响系统的运行,但看到每次启动就报这一堆异常信息,心里也很不爽。

在网上搜索了下解决办法,但是大部分都是只有提问,没有结果,或者就是解决办法不管用。于是,下决心自己去解决。认真查看异常信息,发现如下重要信息:

at org.apache.struts.action.ActionServlet.parseModuleConfigFile(ActionServlet.java:738)
 at org.apache.struts.action.ActionServlet.initModuleConfig(ActionServlet.java:687)

于是,找到对应源代码:ActionServlet中的方法initConfigDigester()

 

if (configDigester != null) {
            return (configDigester);
        }

        // Create a new Digester instance with standard capabilities
        configDigester = new Digester();
        configDigester.setNamespaceAware(true);
        configDigester.setValidating(this.isValidating());//注意此处!!!
        configDigester.setUseContextClassLoader(true);
        configDigester.addRuleSet(new ConfigRuleSet());

        for (int i = 0; i < registrations.length; i += 2) {
            URL url = this.getClass().getResource(registrations[i + 1]);

            if (url != null) {
                configDigester.register(registrations[i], url.toString());
            }
        }

        this.addRuleSets();
 

注意标注【注意的代码行】,其调用的代码如下:

 

 private boolean isValidating() {
        boolean validating = true;
        String value = getServletConfig().getInitParameter("validating");

        if ("false".equalsIgnoreCase(value) || "no".equalsIgnoreCase(value)
            || "n".equalsIgnoreCase(value) || "0".equalsIgnoreCase(value)) {
            validating = false;
        }

        return validating;
    }
 

分析到此处,大家相信都知道怎么回事了。赶紧前往web.xml配置org.apache.struts.action.ActionServlet的地方加上

 

<init-param>
	<param-name>validating</param-name>
	<param-value>false</param-value>
</init-param>
 

启动服务器,果然搞定!
