一。在eclipse新建项目，导入jar包
二 在XML内的配置
<context-param> <param-name>contextConfigLocation</param-name>
//或都 这样 <param-value>classpath*:config/spring*.xml</param-value> <param-value>classpath:</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
三。创建一个bean
public class UserDemo { private int id; private String name; public UserDemo(int id, String name) { super(); this.id = id; this.name = name; } public UserDemo() { super(); // TODO Auto-generated constructor stub } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
四。在applicationContext.xml下的写法
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean id="user" class="test.UserDemo"> <property name="id" value="12"></property> <property name="name" value="name"></property> </bean> </beans>
五 测试连接是否成功
import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class test { private ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml"); @Test public void test(){ UserDemo userDemo=(UserDemo) ac.getBean("user"); System.out.println(userDemo.getId()+userDemo.getName()); } }
