Spring WS - 快速指南

Spring WS - Overview

Spring Web Services（Spring-WS）是Spring社区开发的项目之一。 其主要重点是创建文档驱动的Web服务。 Spring Web Services项目促进了契约优先的SOAP Service Development ，提供了多种创建灵活Web服务的方法，可以通过多种方式处理XML有效负载。

Spring Web服务无缝地使用依赖注入和配置等Spring概念。 Spring-WS需要Spring 3.0版本。 通过契约优先开发，我们从WSDL Contract开始，然后使用JAVA来实现所需的合同。

与JAVA接口生成WSDL/XSD契约的契约最后方法相反。 基于WSDL的合同在合同优先方法中仍然独立于JAVA实施。 如果我们需要更改JAVA接口，则无需将现有WSDL合同中所做的更改传达给Web服务用户。 Spring-WS旨在提供WSDL契约与基于JAVA的实现之间的松散耦合。

特点 (Features)

以下是Spring Web Services的功能 -

• XML Mapping to Objects - 可以使用Message Payload，SOAP Action Header中存储的信息或使用XPath Expression将基于XML的请求映射到任何对象。

• Multiple API Support to parse XML - 除了用于解析传入XML请求的标准JAXP API（DOM，SAX，StAX）之外，还支持其他库，如JDOM，dom4j，XOM。

• Multiple API Support to marshal XML - Spring Web Services使用其Object/XML Mapping模块支持JAXB 1和2，Castor，XMLBeans，JiBX和XStream库。 Object/XML Mapping模块也可以用在非Web服务代码中。

• Spring based configurations - Spring Web Services将Spring Application Contexts用于具有与Spring Web MVC类似的体系结构的配置。

• Integrated WS-Security module - 使用WS-Security模块，您可以签名，加密，解密SOAP消息或对其进行身份验证。

• Support for Acegi Security - 使用Spring Web Services的WS-Security实现，Acegi配置可用于您的SOAP服务。

结构 (Architecture)

Spring-WS项目由五个主要模块组成，下面将对其进行说明。

• Spring-WS Core - 它是主要模块，提供WebServiceMessage和SoapMessage等中央接口，服务器端框架，强大的消息调度功能以及实现Web服务端点的支持类。 它还提供Web Service使用者客户端作为WebServiceTemplate 。

• Spring-WS Support - 该模块为JMS，电子邮件等提供支持。

• Spring-WS Security - 该模块负责提供与核心Web服务模块集成的WS-Security实现。 使用此模块，我们可以添加主要令牌，签名，加密和解密SOAP消息。 此模块允许使用现有的Spring Security Implementation进行身份验证和授权。

• Spring XML - 此模块为Spring Web Services提供XML支持类。 该模块由Spring-WS框架内部使用。

• Spring OXM - 此模块提供XML与对象映射的支持类。

Spring WS - Environment Setup

在本章中，我们将了解在基于Windows和Linux的系统上设置Spring-WS的过程。 Spring-WS可以通过几个简单的步骤轻松安装并与您当前的Java environment和MAVEN集成，而无需任何复杂的设置过程。 安装时需要用户管理。

系统需求 (System Requirements)

下表列出了系统要求，后续步骤将指导我们完成环境设置过程。

JDK	Java SE 2 JDK 1.5或以上版本
Memory	1 GB RAM（推荐）
磁盘空间	没有最低要求
操作系统版本	Windows XP或更高版本，Linux

现在让我们继续安装Spring-WS的步骤。

第1步:验证Java安装

首先，您需要在系统上安装Java软件开发工具包（SDK）。 要验证这一点，请根据您正在使用的平台执行以下两个命令中的任何一个。

如果Java安装已正确完成，那么它将显示Java安装的当前版本和规范。 下表给出了示例输出。

平台	命令	样本输出
Windows	打开命令控制台并输入 - \> java -version	Java版“1.7.0_60” Java（TM）SE运行时环境（版本1.7.0_60-b19） Java Hotspot（TM）64位服务器VM（内置24.60-b09，混合模式）
Linux	打开命令终端并输入 - $ java -version	java版“1.7.0_25” 打开JDK运行时环境（rhel-2.3.10.4.el6_4-x86_64） 打开JDK 64位服务器VM（内置23.7-b01，混合模式）

• 我们假设本教程的读者在他们的系统上安装了Java SDK版本1.7.0_60。

• 如果您没有Java SDK，请从https://www.oracle.com/technetwork/java/javase/downloads/index.html下载其当前版本并安装它。

第2步:设置Java环境

将环境变量JAVA_HOME为指向计算机上安装Java的基本目录位置。

S.No.	平台和描述
1	Windows 将JAVA_HOME设置为C:\ProgramFiles\java\jdk1.7.0_60
2	Linux 导出JAVA_HOME =/usr/local/java-current

将Java编译器位置的完整路径附加到系统路径。

S.No.	平台和描述
1	Windows 将字符串“C:\Program Files\Java\jdk1.7.0_60\bin”附加到系统变量PATH的末尾。
2	Linux 导出PATH = $ PATH:$ JAVA_HOME/bin/

如上所述，从命令提示符执行命令java -version 。

第3步:下载Maven存档

从https://maven.apache.org/download.cgi下载Maven 3.3.3

OS	存档名称
Windows	apache-maven-3.3.3-bin.zip
Linux	apache-maven-3.3.3-bin.tar.gz
Mac	apache-maven-3.3.3-bin.tar.gz

第4步:提取Maven存档

将存档解压缩到要安装Maven 3.3.3的目录。 将从存档创建子目录apache-maven-3.3.3。

OS	位置（根据您的安装可能会有所不同）
Windows	C:\Program Files\Apache Software Foundation\apache-maven-3.3.3
Linux	/usr/local/apache-maven
Mac	/usr/local/apache-maven

第5步:设置Maven环境变量

将M2_HOME，M2和MAVEN_OPTS添加到环境变量中。

OS	output
Windows	使用系统属性设置环境变量。 M2_HOME = C:\Program Files\Apache Software Foundation\apache-maven-3.3.3 M2 =％M2_HOME％\ bin中 MAVEN_OPTS = -Xms256m -Xmx512m
Linux	打开命令终端并设置环境变量。 export M2_HOME =/usr/local/apache-maven/apache-maven-3.3.3 出口M2 = $ M2_HOME/bin 导出MAVEN_OPTS = -Xms256m -Xmx512m
Mac	打开命令终端并设置环境变量。 export M2_HOME =/usr/local/apache-maven/apache-maven-3.3.3 出口M2 = $ M2_HOME/bin 导出MAVEN_OPTS = -Xms256m -Xmx512m

步骤6:将Maven bin目录位置添加到系统路径

现在将M2变量附加到系统路径。

OS	output
Windows	将字符串;％M2％附加到系统变量Path的末尾。
Linux	export PATH = $ M2:$ PATH
Mac	export PATH = $ M2:$ PATH

第7步:验证Maven安装

现在打开控制台，执行以下mvn命令。

OS	任务	命令
Windows	打开命令控制台	c:\> mvn --version
Linux	打开命令终端	$ mvn --version
Mac	开放式终端	机器:

最后，验证上述命令的输出，这些命令应如下所示 -

OS	output
Windows	Apache Maven 3.3.3（7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T17:27:37 + 05:30） Maven home:C:\Program Files\Apache Software Foundation\apache-maven-3.3.3 Java版本:1.7.0_75，供应商:Oracle Corporation Java home:C:\Program Files\Java\jdk1.7.0_75\jre 默认语言环境:en_US，平台编码:Cp1252
Linux	Apache Maven 3.3.3（7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T17:27:37 + 05:30） Maven home:/usr/local/apache-maven/apache-maven-3.3.3 Java版本:1.7.0_75，供应商:Oracle Corporation Java home:/usr/local/java-current/jdk1.7.0_75/jre
Mac	Apache Maven 3.3.3（7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T17:27:37 + 05:30） Maven home:/usr/local/apache-maven/apache-maven-3.3.3 Java版本:1.7.0_75，供应商:Oracle Corporation Java home:/Library/Java/Home/jdk1.7.0_75/jre

第8步:安装Eclipse IDE

本教程中的所有示例都是使用Eclipse IDE编写的。 建议读者在其计算机上安装最新版本的Eclipse。 要安装Eclipse IDE，请从以下链接https://www.eclipse.org/downloads/下载最新的Eclipse二进制文件。 下载安装后，将二进制分发包解压缩到方便的位置。

例如，在Windows上的C:\eclipse或Linux/Unix上的/usr/local/eclipse ，最后适当地设置PATH变量。 可以通过在Windows机器上执行以下命令来启动Eclipse，或者只需双击eclipse.exe即可。

%C:\eclipse\eclipse.exe

可以通过在UNIX（Solaris，Linux等）计算机上执行以下命令来启动Eclipse -

$/usr/local/eclipse/eclipse

成功启动后，如果一切正常，那么它应显示以下屏幕 -

第9步:设置Apache Tomcat

我们可以从https://tomcat.apache.org/下载最新版本的Tomcat。 下载安装后，将二进制分发包解压缩到方便的位置。 例如，在Windows机器上的C:\apache-tomcat-7.0.59 ，或在Linux/Unix机器上的/usr/local/apache-tomcat-7.0.59 ，然后设置CATALINA_HOME环境变量指向安装地点。

可以通过在Windows机器上执行以下命令来启动Tomcat，也可以只需双击startup.bat即可

%CATALINA_HOME%\bin\startup.bat
or
C:\apache-tomcat-7.0.59\bin\startup.bat

可以通过在UNIX（Solaris，Linux等）机器上执行以下命令来启动Tomcat -

$CATALINA_HOME/bin/startup.sh
or
/usr/local/apache-tomcat-7.0.59/bin/startup.sh

成功启动后，Tomcat附带的默认Web应用程序将通过访问 - http://localhost:8080/ 。 如果一切正常，那么它应该显示以下屏幕 -

有关配置和运行Tomcat的更多信息，请参阅此处包含的文档以及Tomcat网站 - https://tomcat.apache.org

可以通过在Windows机器上执行以下命令来停止Tomcat -

%CATALINA_HOME%\bin\shutdown
or
C:\apache-tomcat-7.0.59\bin\shutdown

可以通过在UNIX（Solaris，Linux等）计算机上执行以下命令来停止Tomcat -

$CATALINA_HOME/bin/shutdown.sh
or
/usr/local/apache-tomcat-7.0.59/bin/shutdown.sh

完成最后一步后，我们准备继续进行第一个Web服务示例，我们将在下一章中讨论。

Spring WS - First Application

让我们开始使用Spring-WS Framework编写一个基于SOAP的实际Web服务。 在我们开始使用Spring-WS框架编写第一个示例之前，我们必须确保正确设置Spring-WS环境，如Spring Web Services - Environment Setup一章中所述。 我们假设读者具有Eclipse IDE的一些基本工作知识。

因此，让我们继续编写一个简单的Spring WS应用程序，它将公开一个Web服务方法来预订HR门户中的休假。

Contract-first Approach

Spring-WS使用契约优先方法，这意味着我们应该在编写任何基于JAVA的实现代码之前准备好XML Structures 。 我们正在定义一个LeaveRequest对象，它有子对象 - Leave和Employee。

以下是必需的XML构造 -

Leave.xml

<Leave xmlns = "http://iowiki.com/hr/schemas">
   <StartDate>2016-07-03</StartDate>
   <EndDate>2016-07-07</EndDate>
</Leave>

Employee.xml

<Employee xmlns = "http://iowiki.com/hr/schemas">
   <Number>404</Number>
   <FirstName>Mahesh</FirstName>
   <LastName>Parashar</LastName>
</Employee>

LeaveRequest.xml

<LeaveRequest xmlns = "http://iowiki.com/hr/schemas">
   <Leave>
      <StartDate>2016-07-03</StartDate>
      <EndDate>2016-07-07</EndDate>
   </Leave>
   <Employee>
      <Number>404</Number>
      <FirstName>Mahesh</FirstName>
      <LastName>Parashar</LastName>
   </Employee>
</LeaveRequest>

hr.xsd

<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema"
   xmlns:hr = "http://iowiki.com/hr/schemas"
   elementFormDefault = "qualified"
   targetNamespace = "http://iowiki.com/hr/schemas">
   <xs:element name = "LeaveRequest">
      <xs:complexType>
         <xs:all>
            <xs:element name = "Leave" type = "hr:LeaveType"/>
            <xs:element name = "Employee" type = "hr:EmployeeType"/>
         </xs:all>
      </xs:complexType>
   </xs:element>
   <xs:complexType name = "LeaveType">
      <xs:sequence>
         <xs:element name = "StartDate" type = "xs:date"/>
         <xs:element name = "EndDate" type = "xs:date"/>
      </xs:sequence>
   </xs:complexType>
   <xs:complexType name = "EmployeeType">
      <xs:sequence>
         <xs:element name = "Number" type = "xs:integer"/>
         <xs:element name = "FirstName" type = "xs:string"/>
         <xs:element name = "LastName" type = "xs:string"/>
      </xs:sequence>
   </xs:complexType>
</xs:schema>

创建项目

现在让我们打开命令控制台，转到C:\MVN目录并执行以下mvn命令。

C:\MVN>mvn archetype:generate -DarchetypeGroupId = org.springframework.ws
-DarchetypeArtifactId = spring-ws-archetype -DgroupId = com.iowiki.hr
-DartifactId = leaveService

Maven将开始处理并将创建完整的Java Application Project Structure。

在Eclipse中导入项目

按照下面给出的步骤在Eclipse中导入项目。

• 打开Eclipse。

• 选择File → Import →选项。

• 选择Maven项目选项。 单击“下一步”按钮。

• 选择项目位置，其中使用Maven创建了leaveService project 。

• 单击完成按钮。

运行项目

完成创建源文件和配置文件后，导出应用程序。 右键单击应用程序，使用Export→WAR File选项并将leaveService.war文件保存在Tomcat的webapps文件夹中。

启动Tomcat服务器并确保我们能够使用标准浏览器从webapps文件夹访问其他网页。 尝试访问URL - http:// localhost:8080/leaveService/leave.wsdl，如果Spring Web Application一切正常，我们应该看到以下屏幕。

Spring WS - Static WSDL

在上一章Spring -WS - First Application中 ，我们使用Spring WS Configuration自动生成了WSDL。 在这种情况下，我们将展示如何使用Spring WS公开现有的WSDL。

步	描述
1	在Spring WS-First Application章节中解释，在com.iowiki包下创建一个名为leaveService的项目。
2	在/ WEB-INF/wsdl子文件夹下创建WSDL leave.wsdl。
3	更新/ WEB-INF子文件夹下的spring-ws-servlet.xml。 我们在这里使用static-wsdl标记而不是dynamic-wsdl。
4	最后一步是创建所有源文件和配置文件的内容，并导出应用程序，如下所述。

/WEB-INF/spring-ws-servlet.xml

运行项目

完成创建源文件和配置文件后，我们应该导出应用程序。 右键单击应用程序，使用Export→WAR File选项并将leaveService.war文件保存在Tomcat的webapps文件夹中。

现在，启动Tomcat服务器并确保我们可以使用标准浏览器从webapps文件夹访问其他网页。 尝试访问URL - http:// localhost:8080/leaveService/leave.wsdl，如果Spring Web Application一切正常，我们将看到以下屏幕。

Spring WS - Writing Server

在本章中，我们将了解如何使用Spring WS创建Web应用程序服务器。

步	描述
1	在Spring WS-First Application章节中解释，在com.iowiki包下创建一个名为countryService的项目。
2	按照以下步骤中的说明创建countries.xsd，域类，CountryRepository和CountryEndPoint。
3	更新/ WEB-INF子文件夹下的spring-ws-servlet.xml。
4	最后一步是为所有源文件和配置文件创建内容并导出应用程序，如下所述。

countries.xsd

<xs:schema xmlns:xs = "http://www.w3.org/2001/XMLSchema" 
   xmlns:tns = "http://iowiki/schemas"

         <xs:enumeration value = "INR"/>
      </xs:restriction>
   </xs:simpleType>
</xs:schema>

创建项目

让我们打开命令控制台，转到C:\MVN目录并执行以下mvn命令。

C:\MVN>mvn archetype:generate -DarchetypeGroupId = org.springframework.ws 
-DarchetypeArtifactId = spring-ws-archetype -DgroupId = com.iowiki 
-DartifactId = countryService

Maven将开始处理并将创建完整的Java Application Project Structure。

创建域类

将countries.xsd复制到C:\mvn\countryService\src\main\resources文件夹中。 让我们打开命令控制台，转到C:\mvn\countryService\src\main\resources目录并执行以下xjc命令以使用countries.xsd生成域类。

C:\MVN\countryService\src\main\resources>xjc -p com.iowiki countries.xsd

Maven将开始处理并将在com.iowiki包中创建域类。

com\iowiki\Country.java
com\iowiki\Currency.java
com\iowiki\GetCountryRequest.java
com\iowiki\GetCountryResponse.java
com\iowiki\ObjectFactory.java

      uk.setCurrency(Currency.GBP);
      uk.setPopulation(63705000);
      countries.add(uk);
   }
   public Country findCountry(String name) {
      Assert.notNull(name);
      Country result = null;
      for (Country country : countries) {
         if (name.trim().equals(country.getName())) {
            result = country;
         }
      }
      return result;
   }
}

运行项目

创建源文件和配置文件后，将countryService.war文件导出到Tomcat的webapps文件夹中。

现在，启动Tomcat服务器并确保我们是否可以使用标准浏览器从webapps文件夹访问其他网页。 对URL发出POST请求 - http:// localhost:8080/countryService /并使用任何SOAP客户端发出以下请求。

<x:Envelope xmlns:x = "http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns:tns = "http://iowiki/schemas">
   <x:Header/>
   <x:Body>
      <tns:getCountryRequest>
         <tns:name>United States</tns:name>
      </tns:getCountryRequest>
   </x:Body>
</x:Envelope>

您将看到以下结果。

Spring WS - Unit Test Server

在本章中，我们将了解如何对使用Spring WS创建的Web应用程序服务进行单元测试。

步	描述
1	更新在Spring WS - Write Server章节中创建的项目countryService。 添加src/test/java文件夹。
2	在-src/test/java/com/iowiki/ws文件夹下创建CustomerEndPointTest.java，然后更新POM.xml，如下所述。
3	在src/main/resources子文件夹下添加spring-context.xml。
4	最后一步是为所有源文件和配置文件创建内容并测试应用程序，如下所述。

Spring WS - Writing Client

在本章中，我们将学习如何使用Spring WS为在Spring WS中创建的Web应用程序服务器创建客户端。

步	描述
1	按照Spring WS-Writing Server一章中的说明，在com.iowiki包下更新项目countryService。
2	在com.iowiki包下的com.iowiki.client包和MainApp.java下创建CountryServiceClient.java，如以下步骤所述。

CountryServiceClient.java

package com.iowiki.client;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;
import com.iowiki.GetCountryRequest;
import com.iowiki.GetCountryResponse;
public class CountryServiceClient extends WebServiceGatewaySupport {
   public GetCountryResponse getCountryDetails(String country){
      String uri = "http://localhost:8080/countryService/";
      GetCountryRequest request = new GetCountryRequest();
      request.setName(country);
      GetCountryResponse response =(GetCountryResponse) getWebServiceTemplate()
         .marshalSendAndReceive(uri, request);
      return response;
   }
}

MainApp.java

package com.iowiki;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import com.iowiki.client.CountryServiceClient;
public class MainApp {
   public static void main(String[] args) {
      CountryServiceClient client = new CountryServiceClient();
      Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
      marshaller.setContextPath("com.iowiki");
      client.setMarshaller(marshaller);
      client.setUnmarshaller(marshaller);
      GetCountryResponse response = client.getCountryDetails("United States");
      System.out.println("Country : " + response.getCountry().getName());
      System.out.println("Capital : " + response.getCountry().getCapital());
      System.out.println("Population : " + response.getCountry().getPopulation());
      System.out.println("Currency : " + response.getCountry().getCurrency());
   }
}

启动Web服务

启动Tomcat服务器并确保我们可以使用标准浏览器从webapps文件夹访问其他网页。

测试Web服务客户端

右键单击Eclipse下应用程序中的MainApp.java，并使用run as Java Application命令。 如果应用程序一切正常，它将打印以下消息。

Country : United States
Capital : Washington
Population : 46704314
Currency : USD

在这里，我们为基于SOAP的Web服务创建了一个Client - CountryServiceClient.java 。 MainApp使用CountryServiceClient对Web服务进行命中，发出post请求并获取数据。

Spring WS - Unit Test Client

在本章中，我们将学习如何对Spring WS中创建的客户端进行单元测试-为Spring WS创建的Web应用程序服务器编写客户端 -使用Spring WS 编写服务器 。

步	描述
1	按照Spring WS-Writing Server一章中的说明，在com.iowiki包下更新项目countryService。
2	在文件夹SRC→Test→Java下的com.iowiki包下创建CountryServiceClientTest.java，如下面给出的步骤中所述。

CountryServiceClientTest.java

package com.iowiki;
import static org.junit.Assert.*;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import com.iowiki.client.CountryServiceClient;
public class CountryServiceClientTest {
   CountryServiceClient client;
   @Before
   public void setUp() throws Exception {
      client = new CountryServiceClient();
      Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
      marshaller.setContextPath("com.iowiki");
      client.setMarshaller(marshaller);
      client.setUnmarshaller(marshaller);
   }
   @Test
   public void test() {
      GetCountryResponse response = client.getCountryDetails("United States");
      Country expectedCountry = new Country();
      expectedCountry.setCapital("Washington");
      Country actualCountry = response.getCountry();
      Assert.assertEquals(expectedCountry.getCapital(), actualCountry.getCapital());
   }
}

启动Web服务

启动Tomcat服务器并确保我们能够使用标准浏览器从webapps文件夹访问其他网页。

单元测试Web服务客户端

让我们打开命令控制台，转到C:\MVN\countryService目录并执行以下mvn命令。

C:\MVN\countryService>mvn test

Maven将开始构建和测试项目。
