Java开发或调用WebService的几种方式总结

作者：小袁搬码

java开发过程中,很多地方都会遇到数据传递,远程获取数据问题,这篇文章主要介绍了Java开发或调用WebService的几种方式的相关资料,文中通过代码介绍的非常详细,需要的朋友可以参考下

一.JDK自带的 JAX-WS 方式开发WebService服务

1.服务端开发与发布

@WebService
public interface JaxWsDemo {
    String helloJaxWS(String userName);
}

@WebService
public class JaxWsDemoImpl implements JaxWsDemo {
    @WebMethod
    @WebResult(name = "jaxWSResult")
    @Override
    public String helloJaxWS(@WebParam(name = "userName")String userName) {
        return "hello," + userName + "This is a Web Service developed through JAX-WS";
    }
}

public class JAXWSPublishMain {
    public static void main(String[] args) {
        String address = "http://127.0.0.1:8888/JaxWSTest";
        Endpoint.publish(address, new JaxWsDemoImpl());
        System.out.println("WebService 服务已发布！");
    }
}

打开浏览器输入http://127.0.0.1:8888/JaxWSTest?wsdl访问，如下面内容

浏览器中输入wsdl文档中的 http://127.0.0.1:8888/JaxWSTest?xsd=1可查看绑定的参数等信息看如下图：

</xs:schema>

-encoding : 指定编码格式

-keep：是否生成java源文件

-d：指定.class文件的输出目录

-s：指定.java文件的输出目录,   此目录必须存在

-p：定义生成类的包名，不定义的话有默认包名

-verbose：在控制台显示输出信息

-b：指定jaxws/jaxb绑定文件或额外的schemas

-extension：使用扩展来支持SOAP1.2
# 举例
wsimport -encoding utf-8 -keep -d D:\temp -p com.lawyer.user -verbose http://IP:port/serverName?wsdl 

2.客户端开发与测试

切换到要生成客户端源码的路径下，如下：

cd F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client>

根据wsdl文档地址生成源码信息：

F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client>
wsimport -d F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client
-keep -verbose http://127.0.0.1:8888/JaxWSTest?wsdl

参数说明：

wsimport : 导入命令,如果使用cxf就换成 wsdl2java  命令 

package demoOne.client;

import demoone.JaxWsDemoImplService;

/**

 **/
public class ClientTest {
    public static void main(String[] args) {
        demoone.JaxWsDemoImplService implService = new JaxWsDemoImplService();
       demoone.JaxWsDemoImpl jaxWsDemo = (demoone.JaxWsDemoImpl)implService.getJaxWsDemoImplPort();
       String aa = jaxWsDemo.helloJaxWS("Tom ");
        System.out.println("调用WebService执行结果："+aa);
    }
}

执行结果：

调用WebService执行结果：hello,Tom This is a Web Service developed through JAX-WS

二.Axis1.4调用.Net返回值为DataSet类型的WebService接口

1.相关说明

2. Axis1.4客户端WebService服务

1.Axis1.4下载

4.maven环境的话，在pom.xml中添加下面的依赖即可

<!--Axis1.4 及其依赖 begin-->

        }
    }

        try {
            call = (Call) service.createCall();
            call.setTargetEndpointAddress(new URL("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"));//WSURL，注意不要带?wsdl
            //调用方法方法前设置相关参数
            call.setOperationName(new QName("http://WebXml.com.cn/", "getSupportDataSet"));
            call.setReturnType(XMLType.XSD_SCHEMA);//返回类型，这里一定要传入 XMLType.XSD_SCHEMA 类型
            call.setUseSOAPAction(true);
            call.setSOAPActionURI("http://WebXml.com.cn/getSupportDataSet");//soapAction
            Object obj = call.invoke((Object[]) null);
            Schema schema = (Schema) obj;
            MessageElement[] messageElements = schema.get_any();
            List messageHead = messageElements[0].getChildren();//消息头,DataSet对象
            List messageBody = messageElements[1].getChildren();//消息体信息,DataSet对象,最终需要解析的数据
            if (messageBody.size() > 0) {
                String head = messageHead.get(0).toString();//消息头,DataSet对象

三. CXF 开发WebService接口

1. jax-ws实现

场景：CXF结合Spring实现发布与调用简单的WebService

package com.ssm.webservice;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

/**
 * Created by IntelliJ IDEA.
 * User: jinshengyuan
 * Date: 2018-11-09
 * Time: 9:04
 * description:
 **/
@WebService
public interface Hello {
     @WebMethod
     @WebResult(name = "result") String sayHello(@WebParam(name = "name") String name);
}


package com.ssm.webservice.impl;

import com.ssm.dao.sysManagement.ComLogMapper;
import com.ssm.model.ComLog;
import com.ssm.service.sysManagement.ComLogService;
import com.ssm.utils.CommonsUtil;
import com.ssm.webservice.Hello;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * Created by IntelliJ IDEA.
 * User: jinshengyuan
 * Date: 2018-11-09
 * Time: 9:06
 * description:
 **/
public class HelloImpl implements Hello {

    //这里跟controller中调用Service一样，使用@Autowired注解自动注入service
    @Autowired
    ComLogService comLogService;
    @Override
    public String sayHello(String name) {
        //从数据库中获取当前系统日期
        Date date = comLogService.getCurrentDatetime();
        String currentDateTime = null;
        if(date != null){
            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            currentDateTime = dateFormat.format(date);
            System.out.println("系统日期："+currentDateTime);
        }

        return "hello," + name + ",当前时间为："+currentDateTime;
    }
}
 <!-- 引入CXF配置文件，低版本(3.0以下)还需引入其他两个文件 -->
    <import resource="classpath:META-INF/cxf/cxf.xml" />

    <!-- 配置方式1   注意：serviceClass为接口类并非接口的实现类 -->
    <jaxws:server serviceClass="com.ssm.webservice.Hello" address="/webServiceTestA"></jaxws:server>
    <!--访问地址：http://localhost:8080/ssm/webService/webServiceTestA?wsdl-->

    <!-- 配置方式2    注意：implementor为接口的具体实现类,与springmvc整合时，推荐使用这种方式，如果使用配置方式1，则会在访问时，提示如下错误：
     org.apache.cxf.interceptor.Fault: Could not instantiate service class com.ssm.webservice.Hello because it is an interface.
     -->
    <jaxws:endpoint implementor="com.ssm.webservice.impl.HelloImpl" address="/webServiceTest"></jaxws:endpoint>
    <!--访问地址：http://localhost:8080/ssm/webService/webServiceTest?wsdl-->

 <!-- cxf服务启动servlet -->
    <servlet>
        <servlet-name>CXFServlet</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFServlet</servlet-name>
        <!--工程名(ssm)后面紧跟的 url-->
        <url-pattern>/webService/*</url-pattern>
    </servlet-mapping>

2. CXF-RESTFul服务实现

JAX-RS是Java提供用于开发RESTful Web服务基于注解(annotation)的API。JAX-RS旨在定义一个统一的规范，使得Java程序员可以使用一套固定的接口来开发REST应用，避免了依赖第三方框架。同时JAX-RS使用POJO编程模型和基于注解的配置并集成JAXB，可以有效缩短REST应用的开发周期。JAX-RS只定义RESTful API，具体实现由第三方提供，如Jersey、Apache CXF等。

JAX-RS包含近五十多个接口、注解和抽象类：

JAX-RS常用注解：
