从Struts版本2.1.8.1升级到2.3.16.3后，某些控制器的映射存在问题。升级之前所有设备都在工作，但是现在60个以上的控制器中有3个出现了下一个错误：
错误[ActionComponent]无法执行操作：//vendor-tree!index
没有为名称空间/和操作名称vendor-tree!index映射的操作。 -[未知位置]
此操作必须在/vendor-tree!index中而不是在//vendor-tree!index中，但是我不明白为什么Struts只在错误的位置寻找这3个Controller。
我在每次请求时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" />它没有任何改变Struts2: method attribute in <s:submit> button doesn't work是另一种情况，无法解决此情况

自定义映射器为
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？
最佳答案
当我在没有输入方法<@s.action name="vendor-tree" executeResult="true"/>的情况下执行动作标签时，Struts会抛出缺少的执行方法错误。我重命名了我的输入法来执行，现在一切正常。
