今天在写webservice例子时，遇到一个问题就是在接口实现类中想注入Bean实例，发现不能注入，得到的对象为空。后来经过查找，发现是如果要在webservice接口实现中可以使用注解式注入Bean，与平常写的配置有点不同，代码如下：

view plaincopy to clipboardprint?
@WebService(serviceName="UserService",targetNamespace="http://channel.service.teedry.com",portName="UserServicePort",endpointInterface="com.teedry.webservices.channel.UserService")   
@Features(features = "org.apache.cxf.feature.LoggingFeature")   
public class UserServiceImpl implements UserService {   
  
   
    @Autowired  
    private UserManager userManager;   
      
    public List<User> finAllUser() {   
           
        List<User> list = null;   
        try{   
            if(userManager == null){   
                System.out.println("为空对象");   
  
            }   
           list = userManager.findAllUser();   
        }catch (Exception e) {   
           e.printStackTrace();   
        }finally{   
            return list;   
        }   
         
    }   
  
    @Override  
    public OperatorResult insert(String name, String password) {   
        OperatorResult operatorResult = new OperatorResult();   
        try{   
           User user =  new User();   
           user.setName(name);   
           user.setPassword(password);   
           userManager.insertUser(user);   
            
           operatorResult.setRetCode(1);   
           operatorResult.setRetMsg("操作成功");   
       }catch (Exception e) {   
           operatorResult.setRetCode(0);   
           operatorResult.setRetMsg("操作失败");   
           e.printStackTrace();   
    }finally{   
        return operatorResult;   
    }   
         
    }   
  
}  
@WebService(serviceName="UserService",targetNamespace="http://channel.service.teedry.com",portName="UserServicePort",endpointInterface="com.teedry.webservices.channel.UserService")
@Features(features = "org.apache.cxf.feature.LoggingFeature")
public class UserServiceImpl implements UserService {


    @Autowired
    private UserManager userManager;
   
    public List<User> finAllUser() {
        
        List<User> list = null;
        try{
            if(userManager == null){
                System.out.println("为空对象");

            }
           list = userManager.findAllUser();
        }catch (Exception e) {
           e.printStackTrace();
        }finally{
            return list;
        }
      
    }

    @Override
    public OperatorResult insert(String name, String password) {
        OperatorResult operatorResult = new OperatorResult();
        try{
           User user =  new User();
           user.setName(name);
           user.setPassword(password);
           userManager.insertUser(user);
         
           operatorResult.setRetCode(1);
           operatorResult.setRetMsg("操作成功");
       }catch (Exception e) {
           operatorResult.setRetCode(0);
           operatorResult.setRetMsg("操作失败");
           e.printStackTrace();
    }finally{
        return operatorResult;
    }
      
    }

}

刚开始的配置：

view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>  
  
<!-- START SNIPPET: beans -->  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:jaxws="http://cxf.apache.org/jaxws"  
    xsi:schemaLocation="   
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd   
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">  
  
    <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" />  
  
    <jaxws:endpoint id="userService"   address="/UserService"　implementor="com.teedry.webservices.channel.UserServiceImpl"  />  
<!-- END SNIPPET: beans -->  
<?xml version="1.0" encoding="UTF-8"?>

<!-- START SNIPPET: beans -->
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

<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" />

<jaxws:endpoint id="userService"   address="/UserService"　implementor="com.teedry.webservices.channel.UserServiceImpl"  />
<!-- END SNIPPET: beans -->


经过运行，发现Bean实体不能注入，后改为如下配置，Bean实例可以注入

view plaincopy to clipboardprint?
<?xml version="1.0" encoding="UTF-8"?>  
  
<!-- START SNIPPET: beans -->  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:jaxws="http://cxf.apache.org/jaxws"  
    xsi:schemaLocation="   
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd   
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">  
  
    <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" />  
  
    <jaxws:endpoint id="userService"   address="/UserService" >  
      <jaxws:implementor ref="UserService" />  
    </jaxws:endpoint>  
         
      <!-- 实现WebService的bean -->  
    <bean id="UserService" class="com.teedry.webservices.channel.UserServiceImpl" />  
</beans>  
<!-- END SNIPPET: beans -->
