升级到struts-2.3.32, 发现无法调用getter方法
public class Action { private Map<String, String> yTypeList = new LinkedHashMap<String, String>(); // getYtypeList public Map<String, String> getYTypeList() { yTypeList.put("a", "invalid yTypeList a"); yTypeList.put("b", "invalid yTypeList b"); return yTypeList; } }经研究，发现是老代码不符合JavaBean的规范，导致ognl-3.0.19无法读取getter方法。
后来修改了ognl的源码， 修复了两个bugs， 问题解决。
修改了OgnlRuntime的方法
/** * cache get methods */ public static Method getGetMethod(OgnlContext context, Class targetClass, String propertyName) throws IntrospectionException, OgnlException { // Cache is a map in two levels, so we provide two keys (see comments in ClassPropertyMethodCache below) Method method = cacheGetMethod.get(targetClass, propertyName); if (method != null) return method; // By checking key existence now and not before calling 'get', we will save a map resolution 90% of the times if (cacheGetMethod.containsKey(targetClass, propertyName)) { if (method != null) { return method; } } method = _getGetMethod(context, targetClass, propertyName); // will be null if not found - will cache it anyway if (method == null) { method = getReadMethod(targetClass, propertyName, 0); } cacheGetMethod.put(targetClass, propertyName, method); return method; }ognl修改后的版本在: https://github.com/547825809/ognl
