如何在现有的 Web 项目中集成 Web 服务? [英] How to integrate Web-service in existing Web project?

问题描述

我是 Web 服务的新手，我想将 Web 服务集成到我现有的 Web 项目中，但我很困惑如何去做.谁能告诉我怎么做?

对于我正在使用的项目:

• Spring 框架
• 休眠
• 基于 Pojo(不使用 ant builder，hibernate.cfg.xml)
• 日蚀

假设我有包含 getTenderTitleForSecurityDeposit() 函数的 SecurityDepositServiceImpl 类，那么我如何为此做网络服务?

解决方案

实现 Web 服务的快速方法如下:

• 确保以下 jars 可用于您的 web 应用程序:jaxws-rt.jar;jaxb-impl.jar;流缓冲.jar;政策.jar;jaxws-api.jar;stax-ex.jar;gmbal-api-only.jar;管理api.jar

• 在您的 WEB-INF 文件夹中创建一个sun-jaxws.xml"文件，并填写以下内容:

<块引用>

• 在您的 web.xml 中添加以下代码段:

<块引用>

 <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class></监听器><小服务程序><servlet-name>WebServices</servlet-name><servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class><启动时加载>1</启动时加载><servlet-mapping><servlet-name>WebServices</servlet-name><url-pattern>/ws/*</url-pattern></servlet-mapping>

• 创建您的类 com.foo.ws.MyWebServiceClass 并注释您喜欢提供的内容:

<块引用>

@WebService(serviceName="MyServices")公共类 MyWebServiceClass 扩展 SpringBeanAutowiringSupport {@WebMethod公共列表<字符串>myMethodExposed(字符串用户名){列表<字符串>toret = new ArrayList();toret.add("你好世界");toret.add("美丽人生");返回 toret;}}

等等:您的网络服务已准备就绪.

I am new to Web-Services, I want to integrate Web-service in my existing web project, but I am confused how to do it. Can any one tell me how to do it?

For my project I am using:

• Spring Framework
• Hibernate
• Pojo based (not using ant builder, hibernate.cfg.xml)
• Eclipse

Suppose I have SecurityDepositServiceImpl class that contain getTenderTitleForSecurityDeposit() function, then how I do web-service for that?

解决方案

A quick way to implement a web service is the following one:

• Be sure that the following jars will be available to your webapp: jaxws-rt.jar; jaxb-impl.jar; streambuffer.jar; policy.jar; jaxws-api.jar; stax-ex.jar; gmbal-api-only.jar; management-api.jar

• Create a "sun-jaxws.xml" file on your WEB-INF folder and fill it with the following:

<?xml version="1.0" encoding="UTF-8"?>
<endpoints version="2.0" xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime">
  <endpoint 
      implementation="com.foo.ws.MyWebServiceClass"

      name="MyServices" 
      url-pattern="/ws/theUrlILikeTheMost"
      />
</endpoints>

• Add in your web.xml the following snippet:

    <listener>
      <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>WebServices</servlet-name>
        <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

• Create your class com.foo.ws.MyWebServiceClass and annotate what you like to provide:

@WebService(serviceName="MyServices")
public class MyWebServiceClass extends SpringBeanAutowiringSupport {
    @WebMethod
    public List<String> myMethodExposed(String username) {
      List<String> toret = new ArrayList<String>();
      toret.add("Hello world");
      toret.add("Life id beautiful");
      return toret;
    }
}

et voila: your web service is ready.
