二:建项目
1.新建普通的java项目
2.新建lib文件夹,并将jar包复制粘贴进去
3.将lib包进行buid path
然后将需要的jar从firstSpring中导入
然后reply和ok
4.这时的效果
5.新建包
类包:
XML包
6.新建类
第一个接口
1 package main.java.com.sommer.learn;
2
3 public interface HelloWorld {
4 public String sayHi();
5 }
实现类
1 package main.java.com.sommer.learn;
2
3 public class HelloWorldImpl implements HelloWorld{
4 @Override
5 public String sayHi() {
6 return "hahahahahha";
7 }
8
9 }
7.新建xml文件
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans
3 xmlns="http://www.springframework.org/schema/beans"
4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5 xsi:schemaLocation="http://www.springframework.org/schema/beans
6 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
7
8 <bean id="helloWorld" class="main.java.com.sommer.learn.HelloWorldImpl"></bean>
9 </beans>
8.新建主函数
1 package main.java.com.sommer.learn;
2 import org.springframework.context.ApplicationContext;
3 import org.springframework.context.support.ClassPathXmlApplicationContext;
4
5 public class Main {
6 public static void main(String[] args) {
7 ApplicationContext apc = new ClassPathXmlApplicationContext("springXML/HelloWorld.xml");
8 HelloWorld hello = apc.getBean("helloWorld",HelloWorld.class);
9 System.out.println(hello.sayHi());
10 }
11 }
9.运行
