1.Bean的配置项：
2.Bean的作用域：
例子：
package com.wuyonghu.insert; public class BeanScope { public void printMes(String meString){ System.out.println("参数的数据是:"+meString); } } 12345678 12345678 <?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <bean id="beanScope" class="com.wuyonghu.insert.BeanScope" scope="prototype"></bean> </beans> 1234567891011121314 1234567891011121314 @Test public void testHello4() { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml"); BeanScope bean = (BeanScope) context.getBean("beanScope"); BeanScope bean1 = (BeanScope) context.getBean("beanScope"); System.out.println(bean==bean1); } 1234567 1234567从测试中的结果我们就可以看到是否该容器中存在的是同一个实例的bean
