Struts 2 - 升级后控制器映射错误

Question

从 Struts 版本 2.1.8.1 升级到 2.3.16.3 后，某些控制器的映射出现问题.升级前一切正常，但现在 60 多个控制器中有 3 个出现下一个错误：

ERROR [ActionComponent] Could not execute action: //vendor-tree!index There is no Action mapped for namespace / and action name vendor-tree!index. - [unknown location]

此操作必须在 /vendor-tree!index 中而不是在 //vendor-tree!index 中，但我不明白为什么 Struts 只在错误的位置查找这 3 个控制器。我根据

的每个请求都将其称为所有这些控制器

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

<constant name="struts.enable.DynamicMethodInvocation" value="true" /> it doesn't change anything

Struts2: method attribute in <s:submit> button doesn't work is a different case, which not resolve this one

}

自定义映射器是

public class HierarchicalRestActionMapper extends RestActionMapper {

    protected void parseNameAndNamespace(String uri, ActionMapping mapping, ConfigurationManager configManager) {

        Set<String> actions = new HashSet<String>();
        PackageConfig packageConfig;

        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();
            actions.addAll(packageConfig.getActionConfigs().keySet());
        }

        // 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);
        }
    }
}

你知道为什么吗？

Answer 1

当我在没有 input 方法的情况下执行动作标记时

<@s.action name="vendor-tree" executeResult="true"/>

Struts 抛出缺少 execute 方法错误。我将我的 input 方法重命名为 execute 现在一切正常。
