Spring之环境搭建、STS工具和第一个Spring程序

一、下载spring的jar包:

地址:https://repo.spring.io/webapp/#/artifacts/browse/tree/General/libs-milestone

 

 下载完后,所需jar包:

 

 

 

 

 导入项目中,并添加到类路径:

 

 还需要一个日志jar包:commons logging.jar

下载地址:https://mvnrepository.com/artifact/commons-logging/commons-logging/1.1.1

 然后下载Spring-tools工具:

下载地址:http://download.springsource.com/release/STS/3.7.2.RELEASE/dist/e4.5/spring-tool-suite-3.7.2.RELEASE-e4.5.1-win32-x86_64.zip。

下载完解压:打开sts。

将之前的那5个jar包导入javaproject里。

创建Spring Bean Configuration File。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
	
	<bean id="student" class="org.ruangong.entity.Student">
		<property name="stuNo" value="20173681"></property>
		<property name="stuName" value="靳晨晨"></property>
		<property name="stuAge" value="21"></property>
	</bean>

</beans>

  创建entity类,创建test类:

package org.ruangong.test;

import org.ruangong.entity.Student;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
	public static void main(String[] args){
//		Student student = new Student();
//		student.setStuNo(20173681);
//		student.setStuName("靳晨晨");
//		student.setStuAge(21);
//		System.out.println(student.toString());
		
		ApplicationContext conext = new ClassPathXmlApplicationContext("applicationContext.xml");
		Student student = (Student)conext.getBean("student");
		System.out.println(student);
	}
}

  

完成第一个Spring程序。

Springioc帮助我们New了对象,并且赋了值。
