package main.java.com.mycompany.bean; /** * Bean * @author Administrator * */ public class HelloWorld { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } /* * 输出信息 */ public void printHello(){ System.out.println("Spring 4 "+this.name); } }

12.HelloWorldTest类中的内容如下
package main.java.com.mycompany.bean; import main.java.com.mycompany.bean.HelloWorld; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class HelloWorldTest { @Test public void helloWorldTest(){ //获取配置文件上下文 ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); //通过上下文获取bean对象,并转换为具体的HelloWorld类 HelloWorld helloWorld = (HelloWorld)context.getBean("helloWorldBean"); //调用HelloWorld类中的打印信息方法 helloWorld.printHello(); } }
