JRT实现原生Webservice发布

之前准备试试Java发布Webservice，开始以为很简单，因为C#发布很简单。后面发现太费劲了，依赖一堆包，下面几种都试了一下：

JAX-WS (Java API for XML Web Services)：这是Java EE平台的标准，用于创建和发布Web服务。JAX-WS提供了一种简单的方法来发布和调用Web服务，它基于SOAP协议。
Apache CXF：这是一个开源框架，用于构建和开发Web服务和RESTful服务。它支持多种协议，包括SOAP和REST。
Axis2：这是另一个开源框架，用于构建和发布SOAP和RESTful Web服务。Axis2是Apache的一个项目，具有高度的可配置性和灵活性。
Spring Boot + Spring Web Services：如果你使用Spring Boot框架，你可以通过集成Spring Web Services来轻松创建和发布Web服务。
Jersey：这是另一个用于构建RESTful Web服务的开源框架。它是JAX-RS规范的一个实现，并且是Java EE 7的一部分。

依赖太多，补了一个又报一个，最终决定放弃算了，反正对外提供Post也行，调别人的服务自己按soapui的串Post就行了。欢哥业余搞了个基础版的soap协议，支持基础类型，这样也不错。我之前介绍过http的本质就是TCP协议上约束发送和响应格式的TCP，并且用C#和M写过测试。

c语言发布http

Cache实现http

Webservice的本质就是基于http的传输协议约定了请求和响应格式，服务器按请求体执行方法，按响应格式组装响应体。没有那么玄乎，任何有TCP协议的语言自己可以比较简单的实现常规http协议，并且在http基础上实现常规的Webservice协议，当然，要实现全套协议还是很费劲的，但是常用的就是最基本的类型。

下面是欢哥实现的Webservice协议：

首先定义服务的注解，服务实现类申明此注解

package JRT.WebService.WS.Annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * WebService特性，作用类，标识该类可以对外发布服务
 */
@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface WebServer
{
    /**
     * 服务名称
     * @return
     */
    public String ServiceName() default "WebServer";

    /**
     * 命名空间
     * @return
     */
    public String XmlNameSpace() default "";
}

然后定义方法注解，要公布Webservice的方法加上此注解

package JRT.WebService.WS.Annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * WebService方法特性，作用于方法，标识方法可对外发布服务,没标识该注解的方法不生成soap文档
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface WebMethod
{
}

让后定义参数注解，可以指定参数名

package JRT.WebService.WS.Annotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * 标识要发布Webservice的方法的参数对外名称
 */
@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
public @interface WebParam
{
    /**
     * 参数名称
     * @return
     */
    public String Name() default "";
}

然后抽取Webservice调用接口

package JRT.WebService.Http;

import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;

/**
 * 抽取的Webservice请求处理接口，WebService基类实现该接口供主请求按接口调用
 */
public interface IBaseWebServiceHandler {
    /**
     * Http get请求，根据请求处理生成wsdl文档
     *
     * @param request  请求对象
     * @param response 响应对象
     * @throws Exception
     */
    void DealGet(HttpServletRequest request, HttpServletResponse response) throws Exception;

    /**
     * Http post请求，解析处理请求的soap文档，反射执行调用方法，并生成项目的soap文档
     *
     * @param request  请求对象
     * @param response 响应对象
     * @throws Exception
     */
    void DealPost(HttpServletRequest request, HttpServletResponse response) throws Exception;
}

实现Webservice基类，返回soap协议和执行请求体，soap协议就在这里面

package JRT.WebService.Http;

import JRT.Core.Util.JsonUtil;
import JRT.Core.Util.LogUtils;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import org.w3c.dom.*;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.transform.stream.StreamResult;
import java.io.BufferedInputStream;
import java.io.ByteArrayInputStream;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.lang.reflect.Method;
import java.nio.charset.Charset;

/**

 */
public class BaseWebServiceHandler implements JRT.WebService.Http.IBaseWebServiceHandler {

     * @throws Exception
     */
    public void DealGet(HttpServletRequest request, HttpServletResponse response) throws Exception {
        response.setCharacterEncoding("UTF-8");   //设置响应内容编码UTF-8
        response.setContentType("text/xml");   //设置响应mime类型为text/xml
        //获取请求的url，wsdl问了里面需要使用该url
        String url = request.getRequestURL().toString();
        //获取当前类名称
        Class clz = this.getClass();
        //根据类名称和请求url生成wsdl文档
        String xml = JRT.WebService.WS.Wsdl.WsdlXmlUtil.GetWsdlXml(clz, url);
        response.getWriter().print(xml);
    }

    /**

        try {

            BufferedInputStream bis = new BufferedInputStream(request.getInputStream());
            //将请求的内容转换成文本，使用utf-8编码
            String req = new String(bis.readAllBytes(), Charset.forName("UTF-8"));
            //简单清理一些格式化字符

访问查询soap

用soapui测试

用我以前包的动态调用Webservice工具测试

用VS生成的代理类测试

能调到后台，但是取不到返回结果，比较奇怪，应该是实现不全的事，无所谓了，一般也不这么弄

这篇的代码能很好的体现Webservice的本质，服务器按Post的约定格式的xml执行方法后按约定格式的xml返回
