Spring MVC项目中CXF webservice @Autowired实战爬坑

项目环境：
Spring 4.2.3
apache cxf 3.1.11
jdk 7
tomcat 7

关键：
(1)导入正确的包
(2)application.xml，x-servlet.xml 和 web.xml

（1）导入正确的包

• maven方式：注意国内目前可用的镜像有阿里云maven，其中的cxf版本比官网落后几个小版本。

<dependency>        <groupId>org.apache.cxf</groupId>        <artifactId>apache-cxf</artifactId>        <version>${国内镜像支持的版本号}</version>        <type>pom</type>  </dependency>

• 官网下载jar包方式：http://cxf.apache.org/download.html

（2）application.xml，x-servlet.xml 和 web.xml

两个重点：

1. 把controller相关的自动注解扫描配置在x-servlet，把其他类的注解扫描配置在application.xml。否则，会出现@Webservice类中使用@Autowired的实例为null的问题。
2. 用@Webservice修饰接口，实现类继承这个接口。那么实现类不能用@Component、@Controller、@Service、@Repository等注释，但是可以在xml中配置bean的方式实现spring注入。这是个bug，目前4.2.3版本还存在这个bug。

具体代码：
application.xml
