spring搭建webservice

Spring可以通过使用JAX-WS API和Spring-WS来搭建Web服务。下面是使用Spring搭建Web服务的步骤：

1.添加Spring Web Services依赖项，例如：

<dependency>
    <groupId>org.springframework.ws</groupId>
    <artifactId>spring-ws-core</artifactId>
    <version>3.0.7.RELEASE</version>
</dependency>

2.创建一个Endpoint类，该类将实现您的Web服务。例如：

@Endpoint
public class MyEndpoint {

    private static final String NAMESPACE_URI = "http://example.com/spring-ws";

    private MyService myService;

    @Autowired
    public MyEndpoint(MyService myService) {
        this.myService = myService;
    }

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "MyRequest")
    @ResponsePayload
    public MyResponse handleMyRequest(@RequestPayload MyRequest request) {
        // 处理请求并返回响应
    }
}

3.创建一个Spring配置文件，例如：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:sws="http://www.springframework.org/schema/web-services"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/web-services http://www.springframework.org/schema/web-services/web-services-2.0.xsd">

    <sws:annotation-driven/>
    <bean id="myService" class="com.example.MyServiceImpl"/>

    <bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>

    <bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
        <constructor-arg ref="marshaller"/>
    </bean>

    <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="contextPath" value="com.example"/>
    </bean>

    <sws:dynamic-wsdl id="myWsdl" portTypeName="MyPort" locationUri="/ws">
        <sws:xsd location="/WEB-INF/my.xsd"/>
    </sws:dynamic-wsdl>

    <sws:interceptors>
        <bean class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor"/>
    </sws:interceptors>

</beans>

4.在web.xml中添加Spring的DispatcherServlet，例如：

<servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/ws/*</url-pattern>
</servlet-mapping>

5.启动您的Web服务，例如：

public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

}
