在apache-tomcat-7.0.109中运行Structs2碰到几个问题，
1， No result defined for action and result input
2， java.lang.NoSuchFieldException: resourceEntries
进行了解决。

问题

No result defined for action and result input

日志报以下错误：

浏览器中输出以下错误：

Struts Problem Report
Struts has detected an unhandled exception:

You are seeing this page because development mode is enabled. mode, or devMode, enables extra debugging behaviors and reports to assist developers. disable this mode, set:

  struts.devMode=false
in your WEB-INF/classes/struts.properties file.

这个解决的办法比较直接简单，参考​​StackOverflow: No result defined for action and result input​​ ， result name="input"没有定义，将

<action name="fileConvert"
      class="cn.hxex.struts.core.convert.action.FileConverterAction">
      <result name="input">/convert/fileConvertOutput.jsp</result>
    </action>

改为：

<action name="fileConvert"
      class="cn.hxex.struts.core.convert.action.FileConverterAction">
      <result>/convert/fileConvertOutput.jsp</result>
      <result name="input">/convert/fileConvertOutput.jsp</result>
    </action>

问题就解决了。

从输出的日志可以看出，在​​LocalizedTextUtil.java​​​这个源代码中，使用反射来找​​org.apache.catalina.loader.WebappClassLoader​​​这个类，再调用​​clearMap​​方法:

private static void clearTomcatCache() {
        ClassLoader loader = getCurrentThreadContextClassLoader();
        // no need for compilation here.
        Class cl = loader.getClass();

            }
        } catch (Exception e) {
            if (LOG.isWarnEnabled()) {
                LOG.warn("Couldn't clear tomcat cache", e, cl.getName());
            }
        }
    }

在​​clearMap​​​方法中，有一个​​cl.getDeclaredField(name)​​​调用，但是在​​org.apache.catalina.loader.WebappClassLoader​​这个类里没有这个属性，所以这里返回java.lang.NoSuchFieldException: resourceEntries错误。

private static void clearMap(Class cl, Object obj, String name)
            throws NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {

        Field field = cl.getDeclaredField(name);
        field.setAccessible(true);

        Object cache = field.get(obj);

        synchronized (cache) {
            Class ccl = cache.getClass();
            Method clearMethod = ccl.getMethod("clear");
            clearMethod.invoke(cache);
        }
    }

问题是：​​public class WebappClassLoader extends WebappClassLoaderBase {​​​是继承自​​WebappClassLoaderBase ​​​父类，在​​WebappClassLoaderBase ​​​父类里有​​resourceEntries​​这个属性（WebappClassLoaderBase.java）:

/**
     * The cache of ResourceEntry for classes and resources we have loaded,
     * keyed by resource path, not binary name. Path is used as the key since
     * resources may be requested by binary name (classes) or path (other
     * resources such as property files) and the mapping from binary name to
     * path is unambiguous but the reverse mapping is ambiguous.
     */
    protected final Map<String, ResourceEntry> resourceEntries =
            new ConcurrentHashMap<>();

解决办法：
参考​struct2在tomcat运行报错–java.lang.NoSuchFieldException resourceEntries​ 和
​​Github: /java/org/apache/catalina/loader/WebappClassLoader.java​​​​Struts2:java.lang.NoSuchFieldException: resourceEntries at java.lang.Class.getDeclaredField(Class.j​​ 以及
反射 getDeclaredField 报错java.lang.NoSuchFieldException

我这里使用的Tomcat版本是​​apache-tomcat-7.0.109​​​，如果使用​​apache-tomcat-7.0.64​​​之前的版本不会有这个问题，经过测试，我使用了​​apache-tomcat-7.0.63​​这个版本问题就解决了。

java.lang.NoSuchMethodError: com.opensymphony.xwork2.ActionContext.get(Ljava/lang/String;)Ljava/lang/Object;

错误：java.lang.NoSuchMethodError: org.apache.jasper.runtime.JspRuntimeLibrary.releaseTag

这个问题是由于从Tomcat版本​​apache-tomcat-7.0.109​​​，改为Tomcat版本​​apache-tomcat-7.0.63​​​，没有把​​workDir="C:\Users\HuiLin_Xiong\workspace\StrutsCore\work​​这个目录里的东西清除掉，版本冲突导致这个问题，进行清除后问题就解决了。

参考​​C:\apache-tomcat-7.0.63\conf\server.xml​​的配置：

<Context path="/StrutsCore" reloadable="true" docBase="C:\Users\HuiLin_Xiong\workspace\StrutsCore" workDir="C:\Users\HuiLin_Xiong\workspace\StrutsCore\work" />

很多地方都说是Jar包的版本不匹配，更换了多个版本，没有解决问题，最后放弃。
