soap转换rest协议，cxf

Apache CXF是一个开源的Web服务框架，它提供了一个开发和部署SOAP和RESTful Web服务的工具。CXF支持SOAP协议，但也可以将SOAP服务转换为RESTful服务。

要将SOAP服务转换为RESTful服务，可以使用CXF的JAX-RS支持。JAX-RS是Java API for RESTful Web Services的缩写，它是Java EE 6规范的一部分。JAX-RS提供了一种简单的方式来创建RESTful Web服务。

以下是将SOAP服务转换为RESTful服务的基本步骤：

1. 在CXF中创建一个新的JAX-RS Web服务。

2. 在新的Web服务中添加适当的注释和方法，以将SOAP请求转换为RESTful请求。

3. 在新的Web服务中添加RESTful响应，以将SOAP响应转换为RESTful响应。

4. 部署新的Web服务并测试它是否按预期工作。

需要注意的是，SOAP和RESTful服务之间存在一些差异。SOAP服务使用XML格式进行通信，而RESTful服务使用JSON或XML格式。此外，SOAP服务通常需要使用WSDL文件来定义服务接口，而RESTful服务通常使用HTTP方法和URL来定义接口。因此，在将SOAP服务转换为RESTful服务时，需要考虑这些差异，并相应地修改代码。

使用Apache CXF编写一个REST到SOAP或SOAP到REST的转换程序

Apache CXF是一个流行的Java Web Services框架，它支持REST和SOAP协议，并且提供了丰富的功能和工具，可以帮助开发者快速开发Web Services应用程序。

以下是使用Apache CXF编写一个REST到SOAP或SOAP到REST的转换程序的示例：

1. 添加依赖

首先需要在项目中添加Apache CXF的依赖，可以在项目的pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-core</artifactId>
    <version>3.4.0</version>
</dependency>
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-transports-http</artifactId>
    <version>3.4.0</version>
</dependency>
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxrs</artifactId>
    <version>3.4.0</version>
</dependency>
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>3.4.0</version>
</dependency>

2. 编写接口

定义一个接口，包含需要暴露的方法，例如：

@Path("/user")
public interface UserService {

    @GET
    @Path("/{id}")
    @Produces("application/json")
    User getUserById(@PathParam("id") String id);

    @POST
    @Path("/")
    @Consumes("application/json")
    void addUser(User user);

}

3. 实现接口

实现接口，并使用CXF提供的注解将其暴露为REST或SOAP服务，例如：

public class UserServiceImpl implements UserService {

    @Override
    public User getUserById(String id) {
        // 从数据库或其他数据源获取用户信息
        User user = new User();
        user.setId(id);
        user.setName("Alice");
        user.setAge(20);
        return user;
    }

    @Override
    public void addUser(User user) {
        // 将用户信息保存到数据库或其他数据源
        System.out.println("Add user: " + user);
    }

}

4. 配置CXF

使用CXF提供的配置方式，将实现类暴露为REST或SOAP服务，例如：

<jaxrs:server id="restUserService" address="/">
    <jaxrs:serviceBeans>
        <ref bean="userService"/>
    </jaxrs:serviceBeans>
</jaxrs:server>

<jaxws:endpoint id="soapUserService" address="/UserService">
    <jaxws:serviceBean>
        <ref bean="userService"/>
    </jaxws:serviceBean>
</jaxws:endpoint>

5. 测试

启动应用程序，并使用浏览器或SOAP客户端发送请求，测试REST或SOAP服务的功能。例如：

REST服务：http://localhost:8080/user/1

SOAP服务：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:user="http://example.com/user">
   <soapenv:Header/>
   <soapenv:Body>
      <user:getUserById>
         <user:id>1</user:id>
      </user:getUserById>
   </soapenv:Body>
</soapenv:Envelope>

以上就是使用Apache CXF编写REST到SOAP或SOAP到REST的转换程序的示例。需要注意的是，该示例仅用于演示，实际应用中还需要进行更多的配置和调整，以满足实际需求。

好的，我可以为您提供一些思路和参考代码，但是需要您提供更具体的需求和条件。

        Service service = new Service();
        service.put(QName.class, qname);
        service.put(BindingInfo.class, bindingInfo);
        service.setInvoker(new HelloInvoker(soapBody));
        EndpointInfo ei = new EndpointInfo(service.getServiceInfos().get(0), "");
        ei.setAddress("http://localhost:8080/hello");
        bindingOperationInfo.setEndpoint(ei);
        SoapMessage soapMsg = new SoapMessage(bindingOperationInfo);
        soapMsg.setContent(Object.class, soapBody);
        soapMsg.setVersion(Soap11.getInstance());
        soapMsg.setExchange(new HelloExchange());

        // create a JAX-WS client
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(Hello.class);
        factory.setAddress("http://localhost:8080/hello");
        Hello client = (Hello) factory.create();

        // invoke the JAX-WS client and get the SOAP response
        SOAPMessage soapResponse = client.sayHello(name);

        // convert the SOAP response to a string and return it
        return soapMessageToString(soapResponse);
    }

    private String soapMessageToString(SOAPMessage soapMessage) throws SOAPException {
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        soapMessage.writeTo(out);
        return new String(out.toByteArray());
    }

    public static void main(String[] args) {
        // create a JAX-RS server
        JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
        factory.setResourceClasses(RestToSoapConverter.class);
        factory.setResourceProvider(RestToSoapConverter.class, new SingletonResourceProvider(new RestToSoapConverter()));
        factory.setAddress("http://localhost:8080/");
        factory.create();

        // create a JAX-WS server
        JAXRSServiceFactoryBean serviceFactory = new JAXRSServiceFactoryBean();
        serviceFactory.setResourceClasses(Hello.class);
        serviceFactory.setResourceProvider(Hello.class, new SingletonResourceProvider(new HelloImpl()));
        serviceFactory.setAddress("http://localhost:8080/hello");
        serviceFactory.create();

        // start the servers
        System.out.println("Server ready...");
        System.in.read();
        System.out.println("Server shutting down...");
        System.exit(0);
    }

    private static class HelloExchange extends org.apache.cxf.message.ExchangeImpl {
    }

    private static class HelloInvoker extends org.apache.cxf.service.invoker.AbstractInvoker {
        private final SOAPBody soapBody;

        public HelloInvoker(SOAPBody soapBody) {
            super(null);
            this.soapBody = soapBody;
        }

        @Override
        public Object invoke(org.apache.cxf.message.Message message, Object... params) throws Exception {
            SOAPMessage soapMessage = message.getContent(SOAPMessage.class);
            soapBody.addDocument(soapMessage.getSOAPBody().extractContentAsDocument());
            return null;
        }
    }

    public static interface Hello {
        public SOAPMessage sayHello(String name);
    }

    public static class HelloImpl implements Hello {

                SOAPFactory soapFactory = SOAPFactory.newInstance();
                SOAPMessage soapMessage = soapFactory.createMessage();
                SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();
                SOAPBody soapBody = soapEnvelope.getBody();
                QName qname = new QName("http://example.com/", "helloResponse", "ns");

                return soapMessage;
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    }

}

以上程序将REST请求转换为SOAP请求，并将SOAP响应转换为字符串返回。您可以根据您的实际需求进行修改和扩展。
