jax-ws和jax-rs_带有JAX-WS和Spring的Web服务应用程序

jax-ws和jax-rs

1.简介

这是一个漫长的等待，但是我最终要发布有关使用Spring创建第一个基于SOAP的Web服务应用程序的教程。 JAX-WS （用于XML Web服务的Java API）是用于以XML格式创建Web服务的一组API，我们最常将其称为基于SOAP的Web服务 ，希望大家都了解基本架构。

2.实施

首先，让我们检查一下pom文件的配置–

pom.xml

<!-- Spring dependencies -->
<dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.2.1.RELEASE</version>
</dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.2.1.RELEASE</version>
</dependency><!-- JAX-WS -->
<dependency><groupId>org.jvnet.jax-ws-commons.spring</groupId><artifactId>jaxws-spring</artifactId><version>1.9</version>
</dependency><dependency><groupId>com.sun.xml.ws</groupId><artifactId>jaxws-rt</artifactId><version>2.2.8</version>
</dependency>

web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>SOAPWebServiceExample</display-name><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>customer</servlet-name><servlet-class>com.sun.xml.ws.transport.http.servlet.WSSpringServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>customer</servlet-name><url-pattern>/customer</url-pattern></servlet-mapping></web-app>

让我们为我们的应用程序创建客户实体。

客户.java

package com.jcombat.entity;public class Customer {private int id;private String name;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}
}

现在让我们创建服务接口及其对应的服务实现类。

CustomerService.java

package com.jcombat.services.customers;import com.jcombat.entity.Customer;public interface CustomerService {public Customer getCustomerById(String customerId);
}

CustomerServiceImpl.java

package com.jcombat.services.customers;import com.jcombat.entity.Customer;public class CustomerServiceImpl implements CustomerService {public Customer getCustomerById(String customerId) {Customer customer = new Customer();customer.setId(123);customer.setName("Abhimanyu");return customer;}
}

下面是applicationContext的外观。

applicationContext.xml

<?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:ws="http://jax-ws.dev.java.net/spring/core"xmlns:wss="http://jax-ws.dev.java.net/spring/servlet"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://jax-ws.dev.java.net/spring/core http://jax-ws.java.net/spring/core.xsdhttp://jax-ws.dev.java.net/spring/servlet http://jax-ws.java.net/spring/servlet.xsd"><bean id="customerService" class="com.jcombat.services.customers.CustomerServiceImpl"></bean><bean id="customerEndpoint" class="com.jcombat.ws.CustomerEndpoint"><property name="service" ref="customerService" /></bean><wss:binding url="/customer"><wss:service><ws:service bean="#customerEndpoint" /></wss:service></wss:binding></beans>

请注意，URL模式（ / customer ）绑定到了Web服务端点实现类（ customerEndpoint ），如上面的代码片段所示。下面是我们的customerEndpoint bean实现类的样子。

CustomerEndpoint.java

package com.jcombat.ws;import javax.jws.WebMethod;
import javax.jws.WebService;import com.jcombat.entity.Customer;
import com.jcombat.services.customers.CustomerService;@WebService(serviceName = "customerService")
public class CustomerEndpoint {private CustomerService service;@WebMethod(exclude = true)public void setService(CustomerService service) {this.service = service;}@WebMethod(operationName = "getCustomer")public Customer getCustomerById(String customerId) {Customer customer = service.getCustomerById(customerId);return customer;}}

请注意，@ WebService批注指示服务器运行时环境将该类的所有公共方法公开为Web服务方法。如果要防止将任何方法公开为Web服务方法，则需要使用@WebMethod（exclude = true）注释该方法，如上面的代码片段所示。同样，如果我们想将Web服务方法命名为与类中指定的实际方法名称不同的名称（ getCustomerById（） ），则需要在@WebMethod批注中添加operationName属性。
