cxf和spring集成的一些事

阅读更多

环境：
cxf-2.1.3，jdk6，jboss7.0.2，spring3.0.6

用cxf+spring开发web service程序很简单，不过有一些集成问题要注意。在此把这几天发现的一些总结一下，最后有一个遗留的问题

1、关于bean的声明

要发布或者要调用的web service接口，需要用@WebService注解声明。不过要注意的是，@WebService注解不会把类声明为spring的bean

可以声明为bean的方式有以下4个：




@Component

写了一个类来证明这一点：

protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {

		ServletContext context = request.getServletContext();

		WebApplicationContext wc = WebApplicationContextUtils
				.getWebApplicationContext(context);

		String[] beans = wc.getBeanDefinitionNames();

		for (String beanName : beans) {
			System.out.println(beanName);
		}
		
		RemedyWebServiceCM remedy = (RemedyWebServiceCM) wc.getBean("remedy");
		
		AcknowledgeRequest message = new AcknowledgeRequest();
		remedy.acknowledge(message);

	}

在控制台可以看到以下几个bean：
20:02:24,120 INFO  [stdout] (http--0.0.0.0-8888-2) helloWorldImpl
20:02:24,120 INFO  [stdout] (http--0.0.0.0-8888-2) helloWorld
20:02:24,120 INFO  [stdout] (http--0.0.0.0-8888-2) remedy

以上3个bean，就分别是由、、生成的

2、如果要在的实现类中注入bean的话，要注意：

错误的写法：

用这种写法，虽然HelloWorldImpl类已经被声明成bean了，但是注入是失败的

准确来说，在spring容器中存在有HelloWorldImpl对应的bean，并且相关的依赖也已经注入了。但是cxf框架得到的HelloWorldImpl，与上述的bean不是同一个对象，这个HelloWorldImpl对象可能是用反射或者其他机制创建出来的，没有任何组件被注入

正确的写法：

在implementor属性中，用#beanName，这样的话，cxf框架得到的HelloWorldImpl，就是spring容器持有的那个bean。当然这有个前提，就是系统中已经存在这个bean。用或者@Component都是OK的，这里支持注解

3、上面说的是，比较简单。但是就比较麻烦

我目前感觉，声明的bean，没办法在别的bean里用@Autowired注入，只能用的方式来注入

@WebService
public interface RemedyWebServiceCM {

	RemedyResponse acknowledge(AcknowledgeRequest arg0);

	RemedyResponse close(CloseRequest arg0);

	RemedyResponse notify(NotifyRequest arg0);

}

public class HelloWorldImpl implements HelloWorld {

	private RemedyWebServiceCM remedy;

	public String sayHi(User theUser) {
		
		AcknowledgeRequest message = new AcknowledgeRequest();
		remedy.acknowledge(message);
		
		return "Hello " + theUser.getName() + " ,your age is "
				+ theUser.getAge();
	}

	public void setRemedy(RemedyWebServiceCM remedy) {
		this.remedy = remedy;
	}
	
}

用这种的方式就可以

@Controller
public class HelloWorldImpl implements HelloWorld {

	@Autowired
	private RemedyWebServiceCM remedy;

	public String sayHi(User theUser) {
		
		AcknowledgeRequest message = new AcknowledgeRequest();
		remedy.acknowledge(message);
		
		return "Hello " + theUser.getName() + " ,your age is "
				+ theUser.getAge();
	}
	
}

用@Autowired加@Component的方式来做，就不行，报以下异常：

说自动注入失败，因为找不到RemedyWebServiceCM类型的bean

试了很久，完全搞不定。也想不通是为啥，因为RemedyWebServiceCM这个类型的bean，明明已经用声明了，而且用配置文件的方式也是能搞定的
