熟悉Spring 3的同学,来帮帮忙呀
刚开始捣鼓Spring,用Spring MVC,但给controller里装配一个service接口的实现类时,死活装不上,麻烦帮忙看下。
用注解的方式,可以正常装配,就是在controller类的属性前注解@Autowired,在服务实现类前注解@Service,这样是可以的,但用XML方式,却不能装配。

这是web.xml文件:
XML code

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

    <!-- 配置Spring配置文件的位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>
    <!-- 使用ContextLoaderListener初始化Spring容器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <!-- 定义Web应用的首页 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>


    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
        
</web-app>
        



这是spring配置文件applicationContext.xml
XML code

<?xml version="1.0" encoding="GBK"?>
<!-- 指定Spring配置文件的Schema信息 -->
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <bean id="productService" class="com.woods.seller.service.impl.ProductServiceImpl">
    </bean>

    <bean id="productController" class="com.woods.seller.controller.ProductController">
    <property name="productSvc" ref="productService"/>
    </bean>


</beans>



这是Spring MVC的配置文件:

XML code

<?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:aop="http://www.springframework.org/schema/aop"
