📜 Spring WS-第一个应用程序

📅 最后修改于: 2020-11-11 06:42:39 🧑 作者: Mango

让我们开始使用Spring-WS Framework编写实际的基于SOAP的Web服务。在开始使用Spring-WS框架编写第一个示例之前，我们必须确保按照Spring Web Services-Environment Setup一章中的说明正确设置Spring-WS环境。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 Application，它将公开一个Web服务方法以在HR门户中预订假期。

合同优先法

Spring-WS使用“合同优先”方法，这意味着在编写任何基于JAVA的实现代码之前，我们应该准备好XML结构。我们正在定义一个LeaveRequest对象，该对象具有子对象– Leave和Employee。

以下是必需的XML结构-

离开.xml

Employee.xml

创建项目

现在让我们打开一个命令控制台，进入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.tutorialspoint.hr
-DartifactId = leaveService

Maven将开始处理并将创建完整的Java应用程序项目结构。

现在转到C：/ MVN目录。我们将看到一个创建的Java应用程序项目，名为LeaveService (在artifactId中指定)。更新pom.xml并在以下文件夹中添加HumanResourceService.java和HumanResourceServiceImpl.java – C：\ MVN \ leaveService \ src \ main \ java \ com \ tutorialspoint \ hr \ service文件夹。完成后，在以下文件夹中添加LeaveEndpoint.java – C：\ MVN \ leaveService \ src \ main \ java \ com \ tutorialspoint \ hr \ ws文件夹。

建立项目

现在让我们打开命令控制台，进入C：\ MVN \ leaveService目录并执行以下mvn命令。

C:\MVN\leaveService>mvn clean package

Maven将开始构建该项目。

在Eclipse中导入项目

请按照下面给出的步骤在Eclipse中导入项目。

打开Eclipse。
选择文件→导入→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在其中创建了叶子服务项目。
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。右键单击该应用程序，使用“导出”→“ WAR文件”选项，然后将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。
