Question

我从春天开始。我得到了一个提供的@ RestController-Application，我知道我得到了它。现在我尝试使用POJO并且无法使@Autowire工作。这是我的环境：

The Bean：

package mybeans;

import org.springframework.stereotype.Repository;

@Repository
public class User {
    private String surname;
    private String lastname;
    public String getSurname() {
        return surname;
    }
    public void setSurname(String surname) {
        this.surname = surname;
    }
    public String getLastname() {
        return lastname;
    }
    public void setLastname(String lastname) {
        this.lastname = lastname;
    }
}

守则

package mycode;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;

import mybeans.User;

@Component
public class Main {

    private User user;

    @Autowired
    public void setUser(User user) {
        this.user=user;
    }

    public Main() {
        System.out.println("autowired user is instantiated true/false: " + !(user==null));
    }

    public static void main(String[] args) {
        ApplicationContext context =
                new ClassPathXmlApplicationContext("applicationContext.xml");
//      User user=(User) context.getBean("user");
//      System.out.println("explicit user is instantiated true/false: " + !(user==null));
        new Main();

    }

}

Context-xml

<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/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- enable autowire -->
    <context:annotation-config />

    <context:component-scan base-package="mybeans" />

    <!--  
    <bean id="user" class="mybeans.User" autowire="byName">
        <property name="surname" value="Ulrich" />
        <property name="lastname" value="Schmidt" />
    </bean>
    -->

</beans>

bean＆＃34;用户＆＃34;永远不会变成实例化，即使是明确定义bean（现在是注释）。有人看到了，这里有什么不对吗？非常感谢
