WSDL

definitions 为根节点，属性为

name：WS 名称，默认为“实现类 + Service”

targetNamespace：WS 目标命名空间，默认为“WS 实现类对应包名倒排后构成的地址”

definitions的5个子节点

types：描述了 WS 中所涉及的数据类型

portType：定义了 WS 接口名称portType.name（endpointInterface默认为“WS 实现类所实现的接口”），及其操作名称，以及每个操作的输入与输出消息

message：对相关消息进行了定义（供 types 与 portType 使用）

binding：提供了对 WS 的数据绑定方式

service：WS 名称及其端口名称service_port.name（portName默认为“WS 实现类 + Port”），以及对应的 WSDL 地址

SOAP

header

body

`一`、产品

soap风格 (JAX-WS规范JSR-224)

JAX-WS RI：https://jax-ws.java.net/ Oracle 官方提供的实现

Axis：http://axis.apache.org/

CXF：http://cxf.apache.org/

rest风格 (JAX-RS规范JSR-339)

Jersey：https://jersey.java.net/ Oracle 官方提供的实现

Restlet：http://restlet.com/

RESTEasy：http://resteasy.jboss.org/

CXF：http://cxf.apache.org/

`二`、JDK发布与调用

`1`.发布

定义接口

//此注解必须
@WebService
public interface HelloService {
    String say();
}

实现接口

@WebService(serviceName = "HelloService",
        portName = "HelloServicePort",
        endpointInterface = "org.sllx.practice.jdkws.HelloService")
public class HelloServiceImpl implements HelloService {
    @Override
    public String say() {
        return "helloWorld";
    }
}

发布服务

public class Server {
    public static void main(String[] args){
        String address = "http://localhost:8081/ws/soap/hello";
        HelloService helloService = new HelloServiceImpl();
        Endpoint.publish(address, helloService);
        System.out.println("ws is published [" + address + "?wsdl]");
    }
}

访问http://localhost:8081/ws/soap/hello?wsdl即可查看详情

`2`.调用

静态客户端

wsimport http://localhost:8080/ws/soap/hello?wsdl//通过 WSDL 地址生成 class 文件

jar -cf client.jar . //通过 jar 命令将若干 class 文件压缩为一个 jar 包

rmdir /s/q demo //删除生成的 class 文件（删除根目录即可）

public static void main(String[] args){
     HelloService_Service hss = new HelloService_Service();
     HelloService hs = hss.getHelloServicePort();
     System.out.println(hs.say());
}

动态代理客户端

只需提供HelloService接口，无需jar

public static void main(String[] args){
    try {
        URL wsdl = new URL("http://localhost:8081/ws/soap/hello?wsdl");
        QName serviceName = new QName("http://jdkws.practice.sllx.org/", "HelloService");
        QName portName = new QName("http://jdkws.practice.sllx.org/", "HelloServicePort");
        Service service = Service.create(wsdl, serviceName);
        HelloService helloService = service.getPort(portName, HelloService.class);
        String result = helloService.say();
        System.out.println(result);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

`三`、CXF

User为自定义的POJO类

web发布示例集成spring

`1.`SOAP风格

定义接口

package top.rainynight.sitews.user.ws;

import top.rainynight.sitews.user.entity.User;
import javax.jws.WebService;

@WebService
public interface UserWS {

    User lookOver(int id);
}

实现接口

package top.rainynight.sitews.user.ws;

import top.rainynight.sitews.user.entity.User;
import org.springframework.stereotype.Component;

@Component("userWS")
public class UserWSImpl implements UserWS {

    @Override
    public User lookOver(int id) {
        return new User();
    }
}

调用服务

①静态客户端

public class JaxWsClient {

    public static void main(String[] args) {
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setAddress("http://localhost:8080/ws/user");
        factory.setServiceClass(UserWS .class);

        UserWS userWS = factory.create(UserWS .class);
        User result = userWS .lookOver(1);
        System.out.println(result);
    }
}

②动态代理客户端

public class JaxWsDynamicClient {

    public static void main(String[] args) {
        JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();
        Client client = factory.createClient("http://localhost:8080/ws/user?wsdl");

        try {
            Object[] results = client.invoke("lookOver", 1);
            System.out.println(results[0]);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

③通用动态代理客户端

既可调用 JAX-WS 服务，也可调用 Simple 服务

public class DynamicClient {

    public static void main(String[] args) {
        DynamicClientFactory factory = DynamicClientFactory.newInstance();
        Client client = factory.createClient("http://localhost:8080/ws/user?wsdl");

        try {
            Object[] results = client.invoke("lookOver", 1);
            System.out.println(results[0]);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

④Spring客户端

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"

                  address="http://localhost:8080/ws/user"/>

</beans>

public class UserWSClient{

        UserWS userWS= context.getBean("userWSClient", UserWS.class);
        User result = userWS.lookOver(1);
        System.out.println(result);
    }
}

`2`.REST风格

定义接口

!REST 规范允许资源类没有接口

请求方式注解，包括：@GET、@POST、@PUT、@DELETE

请求路径注解，包括：@Path ，其中包括一个路径参数

数据格式注解，包括：@Consumes（输入）、@Produces（输出），可使用 MediaType 常量

相关参数注解，包括：@PathParam（路径参数）、@FormParam（表单参数），此外还有 @QueryParam（请求参数）

package top.rainynight.sitews.user.ws;

import top.rainynight.sitews.user.entity.User;
import javax.jws.WebService;

@WebService
@Path("/")
public interface UserWS {

    @GET
    @Path("{id:[1-9]{1,9}}")
    @Produces(MediaType.APPLICATION_JSON)
    User lookOver(@PathParam("id") int id);
}

实现接口

package top.rainynight.sitews.user.ws;

import top.rainynight.sitews.user.entity.User;
import org.springframework.stereotype.Component;

@Component("userWS")
public class UserWSImpl implements UserWS {

allowOrigins 设置客户端域名

IE8 中使用 jQuery 发送 AJAX 请求时，需要配置 $.support.cors = true

`～～`警告`～～`

!warning 极重要，cxf在wsdl中发布的targetNamespace是实现类路径，而被调用时却只接受接口路径。所以，请将接口与实现类放在同一路径下，或者在实现类中指定targetNamespace为接口的路径；否则客户端将抛出 ..common.i18n.UncheckedException: No operation was found with the name … 异常
