Spring WS(Web Services)是一款基于Spring开发的轻量级服务框架,它支持SOAP(简单对象访问协议)和WSDL(Web服务描述语言),能够帮助开发者快速开发 WebService 风格的应用程序。
在使用 Spring WS 开发之前,需要满足以下环境要求:
在 pom.xml 文件中添加以下依赖:
<dependencies>
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-ws-core</artifactId>
<version>3.0.7.RELEASE</version>
</dependency>
</dependencies>
创建 Spring WS 的配置文件 spring-ws-config.xml,并添加以下内容:
<?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:sws="http://www.springframework.org/schema/web-services"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/web-services
http://www.springframework.org/schema/web-services/web-services-2.0.xsd">
<!-- 添加命名空间 -->
<sws:annotation-driven />
<!-- 配置 WebService 消息处理器 -->
<bean id="messageDispatcher"
class="org.springframework.ws.server.MessageDispatcher">
<property name="endpointMappings">
<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
<property name="mappings">
<props>
<prop key="{http://www.example.com/demo}foo">fooEndpoint</prop>
</props>
</property>
</bean>
</property>
</bean>
<!-- 配置 WebService 端点 -->
<bean id="fooEndpoint"
class="com.example.demo.endpoint.FooEndpoint">
</bean>
</beans>
上述配置文件主要完成以下几个功能:
创建 FooEndpoint 类,并实现 WebService 端点的逻辑:
package com.example.demo.endpoint;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import org.springframework.ws.server.endpoint.annotation.ResponsePayload;
import com.example.demo.domain.FooRequest;
import com.example.demo.domain.FooResponse;
@Endpoint
public class FooEndpoint {
@PayloadRoot(namespace = "http://www.example.com/demo", localPart = "fooRequest")
@ResponsePayload
public FooResponse processFooRequest(@RequestPayload FooRequest request){
FooResponse response = new FooResponse();
response.setMessage("Hello " + request.getName() + "!");
return response;
}
}
在 Spring 配置文件中添加 WsConfigurerAdapter 类型的 Bean,并实现其 addInterceptors 和 addEndpoints 方法,发布 WebService:
package com.example.demo.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.config.annotation.WsEndpointRegistry;
import org.springframework.ws.config.annotation.WsInterceptors;
import org.springframework.ws.server.EndpointInterceptor;
import com.example.demo.endpoint.FooEndpoint;
@EnableWs
@Configuration
@WsInterceptors
public class WebServiceConfig extends WsConfigurerAdapter {
@Override
public void addInterceptors(List<EndpointInterceptor> interceptors) {
// 添加 WebService 拦截器
}
@Override
public void addEndpoints(WsEndpointRegistry registry) {
registry.registerEndpoint("/demo", new FooEndpoint());
}
@Bean
public WsdlDefinitionHandlerAdapter wsdlDefinitionHandlerAdapter(){
//配置 WSDL 定义处理器适配器
return new WsdlDefinitionHandlerAdapter();
}
}
以上便是使用 Spring WS 开发 WebService 的基本流程,通过配置 Spring WS,实现 WebService 的发布和调用。希望这篇文章对你有所帮助。
