Struts2框架有两个核心配置文件：struts.xml和Struts2默认属性文件default.properties(在struts2-core-2.3.20.jar中)
default.properties可以通过自己在classpath下写一个struts.properties文件进行定制改写
为什么是struts.properties，这可以看org.apache.struts2.config下的DefaultSettings和PropertiesSettings源码
DefaultSettings.java
public DefaultSettings() {
ArrayList list = new ArrayList();
// stuts.properties, default.properties
try {
list.add(new PropertiesSettings("struts"));
} catch (Exception e) {
log.warn("DefaultSettings: Could not find or error in struts.properties", e);
}
PropertiesSettings.java
public PropertiesSettings(String name) {
URL settingsUrl = ClassLoaderUtil.getResource(name + ".properties", getClass());
if (settingsUrl == null) {
if (LOG.isDebugEnabled()) {
LOG.debug(name + ".properties missing");
}
settings = new LocatableProperties();
return;
}
也可以把你想写在struts.properties的自定义配置写在struts.xml文件下
在strut源码StrutsConstants.class包含了所有可配置项

其中

保存了不由struts2处理的路径,我们在struts.properties或者struts.xml中配置即可.
struts.action.excludePattern=/dwr/.*,/dwr/test/.*
正则表达式，并非URL匹配地址
