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
