java - Spring @AutoWired 始终为 null

Question

我正在尝试从我的程序上的另一个系统调用 SOAP 服务。我已经使用 wsimport 命令从 WSDL 生成了所需的 java 类。

这是我的程序的配置

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">

    <display-name>PTDAM Promo Engine</display-name>
    <description>Promo Engine using Elastic Search</description>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/cxf-servlet.xml</param-value>

    </context-param>

    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value>promoengine</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <display-name>CXF Servlet</display-name>
        <servlet-class>
            org.apache.cxf.transport.servlet.CXFServlet
        </servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>


</web-app>

这是我存储配置位置的 xml 配置文件

更新:将 ESCreditRunner 类添加为下面的 bean，但仍然出现相同的错误

cxf-servlet.xml

    <beans xmlns="http://www.springframework.org/schema/beans"

         <context:annotation-config />
         <context:component-scan base-package="ptdam.emoney.webservice.transactions" />

         <import resource="classpath:META-INF/cxf/cxf.xml" />
         <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
         <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

        <!-- Client -->
        <jaxws:client id="topupWebService"
            serviceClass="ptdam.emoney.webservice.transactions.TopupWebService"
            address="http://localhost:8080/ecash-core-engine-dev-mitigasi/services/emoneytopup"

<!-- Beans -->
    <bean id="esCreditRunner" class="com.ptdam.promo.services.ESCreditRunner" />
        />      
    </beans>

以下是我如何使用 @AutoWired 在 testCall() 方法上调用 SOAP 服务 topupWebService..

ESCreditRunner.java

package ptdam.emoney.webservice.transactions;    
public class ESCreditRunner {
        private File statusFile;
        private Properties status;
        private static final Logger logger = Logger.getLogger(ESCreditRunner.class);


        @Autowired
        private TopupWebService topupWebService;
        public void setTopupWebService(TopupWebService topupWebService) {
            this.topupWebService = topupWebService;
        }

        // testing 04/07/2017
        public void testCall(){
            topupWebService.echoTest("Luki");
        }
    }

当我运行 testCall() 方法时，我总是在 topupWebService 变量上收到 NullPointerException。看起来没有正确注入(inject)..

我在这里缺少什么？

您应该在类ESCreditRunner上设置注释@Component
