web.xml中通过contextConfigLocation的读取spring的配置文件

博客分类:

web.xml

contextConfigLocationcontextparamxmlvalue

公司的考勤系统程序,有5个spring配置文件:bean-edu.xml,bean-pub.xml,db-edu.xml,db-pub.xml,timer-system.xml,均放置于src目录下,在web.xml中配置这些文件的代码如下:

Java代码



<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:/db-pub.xml,

classpath:db-edu.xml,

classpath:bean*.xml,

classpath*:timer-system.xml

</param-value>

</context-param>

注意:部署程序启动tomcat之后,log4j显示出 [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [db-pub.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [db-edu.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from file [E:\apache-tomcat-6.0.33-windows-x86\apache-tomcat-6.0.33\webapps\DigitalCampus\WEB-INF\classes\bean-edu.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from file [E:\apache-tomcat-6.0.33-windows-x86\apache-tomcat-6.0.33\webapps\DigitalCampus\WEB-INF\classes\bean-pub.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from URL [file:/E:/apache-tomcat-6.0.33-windows-x86/apache-tomcat-6.0.33/webapps/DigitalCampus/WEB-INF/classes/timer-system.xml]

Java代码



<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:/db-pub.xml,

classpath:db-edu.xml,

classpath*:bean*.xml,

/WEB-INF/classes/timer-system.xml

<!-- classpath*:timer-system.xml-->

</param-value>

</context-param>

[main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [db-pub.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [db-edu.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from file [E:\apache-tomcat-6.0.33-windows-x86\apache-tomcat-6.0.33\webapps\DigitalCampus\WEB-INF\classes\bean-edu.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from file [E:\apache-tomcat-6.0.33-windows-x86\apache-tomcat-6.0.33\webapps\DigitalCampus\WEB-INF\classes\bean-pub.xml] [main] INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from ServletContext resource [/WEB-INF/classes/timer-system.xml]
根据以上两个例子: 1 classpath和classpath*的区别是:前者from class path resource,后者from URL。classpath:只会到你的class路径中查找找文件; classpath*:不仅包含class路径,还包括jar文件中(class路径)进行查找. 2 带不带有/,没有区别。 3 bean*.xml查找的是以bean开头的配置文件,from file 4 classpath*:bean*.xml 为from file. 5 /WEB-INF/classes/timer-system.xml 为from ServletContext resource。

另外: "**/" 表示的是任意目录; "**/applicationContext-*.xml" 表示任意目录下的以"applicationContext-"开头的XML文件。 程序部署到tomcat后,src目录下的配置文件会和class文件一样,自动copy到应用的 WEB-INF/classes目录下
