使用@ImportResource和@Value注解进行资源文件读取

package com.imooc.beanannotation.javabased;import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;@Configuration
@ImportResource("classpath:config.xml")
public class StoreConfig {@Value("${url}")private String url;@Value("${username}")private String username;@Value("${password}")private String password;@Beanpublic MyDriverManager myDriverManager(){return new MyDriverManager(url,username,password);}/*@Bean(name="stringStore",initMethod="init",destroyMethod="destroy")public Store stringStore(){return new StringStore();}*/
}

package com.imooc.beanannotation.javabased;public class MyDriverManager {public MyDriverManager(String url,String userName,String password){System.out.println("url:"+url);System.out.println("userName:"+userName);System.out.println("password:"+password);}
}

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><context:property-placeholder location= "classpath:/config.properties"/></beans>

注意：config.properties要在classpath目录下。

package com.imooc.test.beanannotation;import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;import com.imooc.beanannotation.javabased.MyDriverManager;
import com.imooc.beanannotation.javabased.Store;
import com.imooc.ioc.interfaces.UnitTestBase;@RunWith(BlockJUnit4ClassRunner.class)
public class TestJavabased extends UnitTestBase {public TestJavabased(){super("classpath*:spring-beanannotation.xml");
}@Testpublic void test(){Store store=super.getBean("stringStore");System.out.println(store.getClass().getName());;}@Testpublic void testMyDriverManager(){MyDriverManager manager=super.getBean("myDriverManager");System.out.println(manager.getClass().getName());;}
}

运行结果：

注意：username是当前登录操作系统的用户名

要不重复，修改：

运行结果：
