导入资源不起作用

Question

我刚刚开始学习Spring，它很容易就能生成几个类，并通过construtor arg或setter传递Spring配置文件中的值。

如果我将一个属性引用给另一个配置文件怎么办，考虑我的两个类User和Vehical的简单程序和两个Spring COnfiguration文件FirstBean.xml和SecondBean.xml以及一个带有main方法的App类，如下所示 - < / p>

目录结构 -

User.java -

package com.common;

    public class User {

public String username;
public Vehical vehical;

public User() {
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public Vehical getVehical() {
    return vehical;
}

public void setVehical(Vehical vehical) {
    this.vehical = vehical;
}
}

Vehical.java -

package com.common;

public class Vehical {

public String vehicalname;

public Vehical() {
}

public Vehical(String vehicalname) {
    super();
    this.vehicalname = vehicalname;
}

}

App.java -

package com.main;
import com.common.User;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {

public static void main(String[] args) throws InterruptedException{
    // TODO Auto-generated method stub
    ApplicationContext context=new ClassPathXmlApplicationContext("com/bean/FirstBean.xml");
    User user =(User) context.getBean("userClass");
    String s= user.toString();
    System.out.println(s);
}

}

FirstBean.xml -

    <?xml version="1.0" encoding="UTF-8"?>
    <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.xsd">

    <import resource="com/bean/SecondBean.xml"/>

    <bean id="userClass" name="User" class="com.common.User">
        <property name="username" value="Sushant"></property>
        <property name="vehical" ref="vehicalClass"></property>
    </bean>



</beans>

SecondBean.xml -

?xml version="1.0" encoding="UTF-8"?>
<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.xsd">


<bean id="vehicalClass" name="Vehical" class="com.common.Vehical">
    <constructor-arg value="pulser"></constructor-arg>
</bean>
</beans>

在FirstBean.xml中，我导入了SecondBean.xml资源，并使用ref引用了它，但它没有得到它。我怎么解决这个问题？我不确定我想做的事情是否可能。

Answer 1

替换<import resource="com/bean/SecondBean.xml"/>

<import resource="SecondBean.xml"/>
