spring4笔记----spring4设值注入
2个接口
package com.ij34.servce; public interface people { public void cut(); }
package com.ij34.servce; public interface root { public String chop(); }
实现上面的接口
package com.ij34.web; import com.ij34.servce.people; import com.ij34.servce.root; public class chinese implements people{ private root dog; public root getDog() { return dog; } public void setDog(root dog) { this.dog = dog; }
package com.ij34.web; import com.ij34.servce.root; public class stonechop implements root{ @Override public String chop() { // TODO Auto-generated method stub return "使用石头"; } }
package com.ij34.web; import com.ij34.servce.root; public class ironchop implements root{ @Override public String chop() { // TODO Auto-generated method stub return "使用铁斧"; } }
beans
<?xml version="1.0" encoding="GBK"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd"> <bean id="chinese" class="com.ij34.web.chinese"> // 是chinese不是people <property name="dog" ref="iron"></property> </bean> <bean id="stone" class="com.ij34.web.stonechop"></bean> <bean id="iron" class="com.ij34.web.ironchop"></bean> </beans>
加载bean,实现调用实例
package com.ij34.bean; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.ij34.servce.people; public class test { public static void main(String[] args) throws Exception{ // TODO Auto-generated method stub @SuppressWarnings("resource") ApplicationContext app=new ClassPathXmlApplicationContext("beans.xml"); people p= app.getBean("chinese",people.class); p.cut(); } }
