@Autowired - 找不到依赖项的限定bean [javax.servlet.http.HttpServletRequest]

标签: spring spring-mvc controller autowired

我有一个自动装配HttpServletRequest的Spring Rest Controller:

@Controller
public class AccountSummaryController {
    @Autowired 
    private  HttpServletRequest request;

在我的pom.xml文件中:

 <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
</dependency>

在我的web.xml文件中,

        <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>      
      <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/config/spring-context.xml</param-value>     
        </init-param>
        <init-param>
                <param-name>contextClass</param-name>
                <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
            </init-param>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>com.exelon.passport.ws.config.WebConfiguration</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>   
      </servlet>  
  <context-param>
        <param-name>contextClass</param-name>
        <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </context-param>

我的spring-context.xml文件,我将Spring告诉annotation-config:

<context:component-scan base-package="com.exelon.passport.ws" />

<mvc:annotation-driven />

<mvc:default-servlet-handler/>

<context:annotation-config />

我正在使用Spring 4.3.3.Release,Tomcat 9和java 8,Eclipse Neon 2.

我尝试了以下技巧但没有成功:

<bean class="org.springframework.mock.web.MockServletContext"/>

我也试过非自动装配的解决方案,进入更多错误:

无需自动装配HttpServletRequest。这是一个如何使用它的例子。

@Controller
public class AccountSummaryController {

    @RequestMapping(value = "/yourURL", method = RequestMethod.GET)
    public ModelAndView yourMethod(HttpServletRequest request) {
        ModelAndView mav = new ModelAndView("yourView");
        //Here you can access to the request normally
        return mav;
    }
}
