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 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" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 注解支持 --> <mvc:annotation-driven/> <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 --> <context:component-scan base-package="com.woods.seller"> </context:component-scan> </beans>
