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<Settings> list = new ArrayList<Settings>(); // 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<constant>节点中，java培训如果同时都在两个文件配置了,一个相同的项目, 先加载 struts.xml,再加载struts.properties也就是说 struts.properties 是可以覆盖 struts.xml里面的配置的

在strut源码StrutsConstants.class包含了所有可配置项

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.
