弹簧@AutoWired始终为空

Question

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

这是我的程序配置

网络.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"

<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>

这是我的XML配置文件，我在其中存储了配置位置

更新：在下面添加了ESCreditRunner类作为bean，但仍然得到相同的错误

cxf-servlet.xml

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

这是我如何使用@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变量上得到NullPointerException。看起来没有正确注射。.

我在这里错过了什么？

Answer 1

您应该在类ESCreditRunner上设置注释@Component

Answer 2

您可以尝试使用：

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

如果您的 xml 不在类路径中，则可以使用classpath:**/cxf-servlet.xml

Answer 3

我已经在我的类上使用@Component解决了问题，并将@Autowired设置为从控制器级联调用的所有对象，或者在诸如弹簧 mvc @Autowired错误的设置中检查您的包 类型不满足的"必需"依赖项
