使用CXF service 時容易出現的異常

 

問題一：Could not find destination factory for transport

 

需要加入cxf-rt-transports-http-jetty的jar包，以下是maven中的配置

<dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http-jetty</artifactId>
            <version>2.3.3</version>
</dependency>

 

 

問題二：No operation was found with the name {。。。} ，原因是在當前默認的命名空間中找不到請求的操作方法；

 

解決方法：如果報的是找不到接口，那麼在實現類上配置

@WebService(endpointInterface = "com.cxf.hello.IHelloService",targetNamespace = "http://hello.cxf.com/" ) 
public class HelloServiceImpl implements IHelloService{
  ......
}

 其中targetNamespace中的路徑爲包名的逆序排列；如果報的是找不到相關的javabean類，那麼在相關的類上配置

@XmlType(name = "Hello",namespace = "bean.cxf.com") 
public class Hello{
 ......
}

 該命名空間指向在客戶端調用的時候的對應的bean所在包的逆序（用於將當前的命名空間指向接口，需要重新發布公共接口）

 

問題三：A cycle is detected in the object graph. This will cause infinitely deep XML，原因是在兩個對象中又互相引用了彼此，比如：

public  class UserLogin{
   private int userId;
   private String userName;
   private String userPassword;
   private UserInfo info;
   .........
 }

public class UserInfo {
   private int userId;
   private String sex;
   private String address;
   private UserLogin login;
   .......
 }

 此時需要在類的一端調用中使用@XmlTransient註解（用於get方法上），該註解的作用是不將該屬性解析成Xml文件中的元素

 

問題四：java.net.SocketTimeoutException: Read timed out 

官網解釋：https://cwiki.apache.org/CXF20DOC/client-http-transport-including-ssl-support.html

在客戶端的spring中的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://cxf.apache.org/transports/http/configuration
         http://cxf.apache.org/schemas/configuration/http-conf.xsd"
       default-autowire="byName">

    <http-conf:conduit name="{http://investigation.cxf.spiss.sh.org/}CxfInvestServiceImplService.http--conduit">
         <http-conf:client ConnectionTimeout="500000" ReceiveTimeout="600000"/>
    </http-conf:conduit>

</beans>

 然後在客戶端創建了client之後，接着鍵入如下代碼：

            HTTPConduit http = (HTTPConduit) client.getConduit();
            HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
            httpClientPolicy.setConnectionTimeout(600000);//連接超時時間
            httpClientPolicy.setAllowChunking(false);
            httpClientPolicy.setReceiveTimeout(600000);//接收超時時間
            http.setClient(httpClientPolicy);

 即可解決
