Spring bean没有注入CXF Web服务,为什么?
作者:互联网
我正在编写一个RESTful服务(在JBoss上使用CXF),我在其中使用Spring(Autowired)注入另一个类.但是这个类没有被注入而且是空的.
Web服务接口和类(需要注入的地方)
package com.company.project.web;
@Path("/myws")
public interface IMyWebService {
@POST
@Path("/doSomething")
@Consumes("application/json")
@Produces("application/json")
MyResponse doSomething(MyRequest myRequest)
}
@Service("myWebService")
public class MyWebService implements IMyWebService {
@Autowired
private IMyCore myCore;
public MyResponse doSomething(MyRequest myRequest) {
....
}
}
那必须注入
package com.company.project.biz;
public interface IMyCore {
MyResponse doSomething(MyRequest myRequest);
}
@Component("myCore")
public class MyCore implements IMyCore {
public MyResponse doSomething(MyRequest myRequest) {
.....
}
}
beans.xml中
<?xml version="1.0" encoding="UTF-8"?>

<jaxrs:server id="myWebService" address="/">

<bean class="com.company.project.web.MyWebService" />
</jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="json" value="application/json" />
</jaxrs:extensionMappings>
</jaxrs:server>
</beans>
我的服务处于活动状态(http://localhost:8080/{warname}/myws/doSomething),但MyCore实例未被注入MyWebService(在myCore字段中).它始终为null,我的服务无法按预期工作,而是抛出NullPointerException
尝试通过谷歌收集的所有输入.没运气!非常感谢您的帮助.

解决方法:
尝试将以下方法添加到您的Web服务:
@PostConstruct
public void init() {
SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
}
当前的Web应用程序上下文(通常是ContextLoaderListener加载的上下文)将用于自动装配,因此IMyCore bean必须在上下文侦听器配置文件中定义,而不是在Web服务中定义.
