如果删除了组件扫描,则@Autowired不起作用

Question

我面临的问题是,如果从配置中删除组件扫描标记,注释@Autowired将不再起作用(在所有使用此批注的Java类中)

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

  <context:component-scan base-package="efco.auth" />

here are some beans...

efco.auth包中只有一个类,这个类与以下类EfcoBasketLogic无关.

和一个使用@Autowired的类:

package efco.logic;
    public class EfcoBasketLogic extends BasketLogicImpl {

        @Autowired
        private EfcoErpService erpService;

这个Bean在另一个spring配置文件中定义:

<bean id="BasketLogic" class="efco.logic.EfcoBasketLogic">
    <property name="documentLogic" ref="DocumentLogic" />
    <property name="stateAccess" ref="StateAccess" />
    <property name="contextAccess" ref="ContextAccess" />
  </bean>

如您所见,未定义erpService.其他三个属性在BasketLogicImpl上并且有setter.

我做错了什么？

As Tomasz says, you need <context:annotation-config/> for @Autowired to work. When you had <context:component-scan/>, it implicitly included annotation-config for you.
