java – Spring @Autowired构造函数给出没有找到默认构造函数

package com.service.schedule;

import org.springframework.stereotype.Component;

@Component("outroJob")
public class OutroJob {

    public void printMe() {
        System.out.println("running...");
    }

}

和

package com.service.schedule;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.stereotype.Component;

@Component("testeAutowired")
public class TesteAutowired {

    @Autowired
    public TesteAutowired(OutroJob outroJob) {
        outroJob.printMe();
    }

    public static void main(String[] args) {
        ClassPathResource res = new ClassPathResource("applicationContext.xml");
        XmlBeanFactory ctx = new XmlBeanFactory(res);

        OutroJob outroJob = (OutroJob) ctx.getBean("outroJob");
        outroJob.printMe(); // gives: running...

        ctx.getBean("testeAutowired");
    }
}

这些bean都不在applicationContext.xml上声明

所以,行outroJob.printMe();工作正常…打印“正在运行…”

但当我试图获得“testeAutowired”bean时,它说：

Could not instantiate bean class
[com.service.schedule.TesteAutowired]: No default constructor found;
nested exception is java.lang.NoSuchMethodException:
com.service.schedule.TesteAutowired.

问题是：为什么,如果Spring找到了“outroJob”bean,它不会在TesteAutowired构造函数上自动启动它？

它显然需要做什么……
