spring xml中的propery 的name属性名自来源
今天在运用spring的PropertyPlaceholderConfigurer时发现一个有意思的内容,当你在applicationContext中配置一个PropertyPlaceholderConfigurer的bean时,有location和locations的属性,不明思意location对应一个.properties文件,
locations对应多个.properties文件,冲着想看一下PropertyPlaceholderConfigurer的实现机制,于是查看了spring的源码,发现在PropertyPlaceholderConfigurer中并没有location和locations的属性,于是一路向上在父类PropertiesLoaderSupport中找到了locations的属性,但是没有location属性,奇怪?但在PropertiesLoaderSupport中却有setLocation和setLocations两个方法:
/**
* Set a location of a properties file to be loaded.
* <p>Can point to a classic properties file or to an XML file
* that follows JDK 1.5's properties XML format.
*/
public void setLocation(Resource location) {
this.locations = new Resource[] {location};
}
/**
* Set locations of properties files to be loaded.
* <p>Can point to classic properties files or to XML files
* that follow JDK 1.5's properties XML format.
*/
public void setLocations(Resource[] locations) {
this.locations = locations;
}
这样看来applicationContext.xml中的bean的property的name属性的值,并不是和对应类类中的属性内容是一致的

(注意:看代码的时候留意一下节点的用法:myXML.childNodes[0].childNodes[0].childNodes[0]....xml节点的地方。)
一、建立XML对象:
var myXML = new XML();
二、引用XML文件:
myXML.load("data.xml");
