Spring @AutoWired always null

Question

I'm trying to call SOAP service from another system on my program. I've generated the java classes needed from WSDL by using wsimport command.

Here's my program's configuration

<?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>

and here's my xml configuration file where i store the config location

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

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

         <!-- use this to enable @AutoWired -->
         <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>

and here's how i use the @AutoWired, to call the SOAP service topupWebService .. on the testCall() method

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");
        }
    }

when i run the testCall() method, i always get NullPointerException on the topupWebService variable. It looks like it's not injected properly..

what i'm missing here?

Answer 1

您应该在类ESCreditRunner上设置注释@Component

Answer 2

You can try to use:

 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = "cxf-servlet.xml")

If your xml isn't in classpath, then you can use classpath:**/cxf-servlet.xml

Answer 3

我已经解决了在类上使用@Component并将@Autowired设置为从控制器以级联方式调用的所有对象的问题，或者在类似spring mvc的设置中检查了程序包@Autowired错误类型不满足的“必需”依赖项
