spring bean 加载多个配置文件 <import>

第一步： 新建工程 SecondSpring

工程目录结构如下：

第二步：导入响应的jar包

 <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.3.1.RELEASE</version>
    </dependency>
    
     <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-beans</artifactId>  
            <version>4.3.1.RELEASE</version>  
            <type>jar</type>  
        </dependency>  
  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-webmvc</artifactId>  
            <version>4.3.1.RELEASE</version>  
            <type>jar</type>  
        </dependency>  
  
        <dependency>  
            <groupId>org.springframework</groupId>  
            <artifactId>spring-orm</artifactId>  
            <version>4.3.1.RELEASE</version>  
            <type>jar</type>  
        </dependency>  

第三步： 新增类

Frult.java

package com.xuzhiwen.spring1;

public class Frult {
    private String name;
    private int age;
    
    public void setName(String name) {
        this.name = name;
    }
    
    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Frult [name=" + name + ", age=" + age + "]";
    }
}

第四步：新增配置文件

common.xml

<beans 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-2.5.xsd">
    
    <import resource="xmlfolder/app1.xml" />
</beans>    

第五步： 在 xmlfolder文件夹下新增app1.xml文件

app1.xml

<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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
    
    <bean id="frult" class="com.xuzhiwen.spring1.Frult" 
    p:name="apple" p:age="30"    />    
</beans>    

第六步：编写测试类

Test.java

package com.xuzhiwen.spring1;

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

public class Test {
    public static void main(String[] args) {
        ApplicationContext app = new ClassPathXmlApplicationContext("common.xml");
        Frult f = (Frult) app.getBean("frult");
        System.out.println(f);
    }
}

第七步：运行结果如下

注意
在Spring3，所述替代解决方案是使用 JavaConfig @Import.
