【汇智学堂】-SpringMVC Hello

运行成功后控制台：
步骤：
新建三个文件：

TestDao

package dao;

public interface TestDao {
    public void sayHello();
}

TestDaoImpl

package dao;

public class TestDaoImpl implements TestDao {
    @Override
    public void sayHello(){
        System.out.println("hello springmvc");
    }
}

Test

package test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import dao.TestDao;

public class Test {

    public static void main(String[] args){
        //初始化Spring容器ApplicationContext,加载配置文件
        ApplicationContext appCon=new ClassPathXmlApplicationContext("applicationContext.xml");
        TestDao tt=(TestDao)appCon.getBean("test");
        tt.sayHello();
    }

}

设置资源文件路径

运行Test.main()
就成功了。
