Question

关于Java中Spring IOC的配置问题

Answer 1

.java代码：
package ioc.first;

import ioc.first.service.StoreService;

import java.util.Map;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

public static void main(String[] args) {
// FileSystemResource("D:/a.txt");
// Resource resource=new ClassPathResource("ioc/first/applicationContext.xml");
// BeanFactory context=new XmlBeanFactory(resource);

ApplicationContext context=new ClassPathXmlApplicationContext("ioc/first/applicationContext_autowire.xml");
StoreService service=(StoreService)context.getBean("storeService") ;
service.submitOrder();

// Map env=(Map)context.getBean("env");
// System.out.println(env.get("JAVA_HOME"));
//
// System.out.println(context.getBean("env2"));
}

}

applicationContext_autowire.xml 代码：

<?xml version="1.0" encoding="UTF-8"?>
<beans default-autowire="byType"
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-2.0.xsd">

<bean id="itemDao" class="ioc.first.dao.ItemDaoImpl"/>
<bean id="orderDao" class="ioc.first.dao.OrderDaoImpl"/>
<bean id="oDao1" class="ioc.first.dao.OrderDaoImpl"/>

<bean id="storeService"
class="ioc.first.service.StoreServiceImpl"
autowire="autodetect">
</bean>

</beans>

上面java代码中的//后面是注释。可以不用管 是我用来做测试的.
