Question

从Struts版本 2.1.8.1 升级到 2.3.16.3 后，我对某些控制器的映射存在问题。一切都在升级前工作，但现在60多个控制器中有3个出现下一个错误：

错误[ActionComponent]无法执行操作：//vendor-tree!index 没有针对命名空间/和操作名称vendor-tree!index映射的操作。 - [未知位置]

此操作必须位于/vendor-tree!index而不是//vendor-tree!index，但我不明白为什么Struts只在错误的地方寻找这3个控制器。我在

的每个请求中都称它为所有这些控制器

 <#escape x as x?html>
    <@s.action name="vendor-tree!index" executeResult="true" /> 
 </#escape>

<constant name="struts.enable.DynamicMethodInvocation" value="true" />它不会改变任何内容

Struts2: method attribute in <s:submit> button doesn't work是另一种情况，无法解决此问题

        Configuration configuration = configManager.getConfiguration();

        // get the current set of action names in our packages of interest
        Map<String, PackageConfig> packageConfigs = configuration.getPackageConfigs();
        for (Map.Entry<String, PackageConfig> packageEntry : packageConfigs.entrySet()) {
            packageConfig = packageEntry.getValue();

        }

        // parse the uri into namespace, action, method and id
        Map<String, String> params = URIActionMethodParser.process(uri, actions);

        if (params != null) {
            // update the mapping
            mapping.setNamespace(params.get("namespace"));
            params.remove("namespace");
            mapping.setName(params.get("action"));
            params.remove("action");
            mapping.setParams((Map) params);
        }
    }
}

你知道为什么会这样吗？
