Spring 配置文件getter/setter注入入门

第一步：

类ExternalBatch：

public class ExternalBatch{

//定义一个需要注入的属性

          private File mouFile = null;

 

          public File getMouFile () {
                return mouFile;
          }

          public void setMouFile (File mouFile) {
                this.mouFile = mouFile;
          }

 

}

 

第二步：

配置文件beans.xml (颜色标注为配置内容，蓝色为类名，紫色为注入属性的值):

<?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: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-2.5.xsd 
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context-2.5.xsd 
           http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.5.xsd 
           http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
       
    <bean id="command " class="com.pse.musd.common.ExternalBatch ">
        <property name="mouFile " value="D:\\a.txt "></property>
    </bean>
   
</beans>

 

第三步：

调用注入值类TestSpring：

import org.springframework.context.ApplicationContext;

public class TestSpring{

   public static void main(){

        ApplicationContext ctx = new FileSystemXmlApplicationContext("beans.xml ");       

        ExternalBatch mouCommand = (ExternalBatch)ctx.getBean("command ");
        File mouFile = mouCommand.getMouFile ();

//mouFile的值为文件D:\\a.txt

   }

 

}
