 Packagecom.zyz.db;ImportCom.zyz.dao.PersonDao;ImportOrg.springframework.context.ApplicationContext;ImportOrg.springframework.context.support.ClassPathXmlApplicationContext;ImportOrg.springframework.context.support.FileSystemXmlApplicationContext;ImportOrg.springframework.jdbc.datasource.DriverManagerDataSource;/*** Created by Zyz on 2016-8-5.*/ Public classActest { Public Static voidMain (string[] args) {//Method 1: Use FilesystemxmlapplicationcontextApplicationContext ac1=NewFilesystemxmlapplicationcontext ("Src/main/webapp/web-inf/applicationcontext-jdbc.xml"); Drivermanagerdatasource DataSource= (Drivermanagerdatasource) ac1.getbean ("DataSource"); System.out.println (Datasource.getusername ());//Method 2: Use ClasspathxmlapplicationcontextApplicationContext ac2=NewClasspathxmlapplicationcontext ("Beans.xml"); Persondao Persondao= (Persondao) ac2.getbean ("Persondao");

System.out.println (Persondao.getversion ());

System.out.println (Persondao.getpersons (). Get (0). GetName ());} }

Method 1: Simply specify the relative position of the XML file in the project

You can put the XML file into the Resources folder and then add the Resources folder to Classpath, in idea:
"File", "Project Structure", the dialog box appears, add Resources folder, the system will copy the XML file into the classes folder after compiling and running
