在maven中下載spring的jar包,地址爲:http://maven.springframework.org/release/org/springframework/spring/spring
能夠下載spring各個版本的jar包。app
以4.3.9示例,下載dist的壓縮包maven
在解壓縮後須要用到的核心jar包,有工具
spring-aop.jar (開發AOP特性時須要的JAR), ...beans(處理Bean的jar), ... context(處理spring上下文的jar),...core(spring核心jar),...expersion(spring表達式)測試
還須要第三方的commons-logging.jar https://mvnrepository.com/artifact/commons-logging/commons-logging/1.1.1spa
須要自動提示的時候,須要安裝spring插件 sts插件
地址 https://spring.io/tools/sts/all 下載對應的版本3d
或者直接使用官方提供的sts工具 https://spring.io/tools/stscode
安裝好sts以後,在項目中 新建一個bean configuration 命名叫applicationContext.xmlxml
在xml文件能夠配置bean
以測試Bean Student類來舉例(有三個屬性stuName、stuAge、stuNo)
xml:
<?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="com.beans.Student"> <property name="stuNo" value="2"></property> <property name="stuName" value="ls"></property> <property name="stuAge" value="20"></property> </bean> </beans>
測試類:
package com.test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.beans.Student; public class Test { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); Student student = (Student) context.getBean("student"); System.out.println(student); } }
