ws-client-demo

客户端调用远程服务

http://localhost:8280/services/HelloWorld?wsdl

spring + cfx 配置

maven

添加依赖包

<dependency>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-rt-frontend-jaxws</artifactId>
  <version>3.2.3</version>
</dependency>
<dependency>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-rt-transports-http</artifactId>
  <version>3.2.3</version>
</dependency>

wsdl2java

把 HelloWorld.wsdl 下载到 resources 当中

使用 maven 插件 cxf-codegen-plugin 生成代码

  <plugin>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-codegen-plugin</artifactId>
    <version>3.2.2</version>
    <executions>
      <execution>
        <id>generate-sources</id>
        <phase>generate-sources</phase>
        <configuration>
          <sourceRoot>${project.build.directory}/generated/cxf</sourceRoot>
          <wsdlOptions>
            <wsdlOption>
              <wsdl>${basedir}/src/main/resources/HelloWorld.wsdl</wsdl>
            </wsdlOption>
          </wsdlOptions>
        </configuration>
        <goals>
          <goal>wsdl2java</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

maven compile 任务完成之后在target\generated\cxf\com\example\demo\ws 下会有很多文件

    CurrentDate.java
    CurrentDateResponse.java
    HelloWorld.java
    HelloWorldImplService.java
    ObjectFactory.java
    package-info.java
    SayHi.java
    SayHiResponse.java

调用 WebService

使用 spring

把 HelloWorld.java 复制到 srcmainjavacomexampledemows 目录下

同时 HelloWorld.java 里面 @XmlSeeAlso({ObjectFactory.class})这行代码删掉

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

    <jaxws:client id="helloClient"
                  serviceClass="com.example.demo.ws.service.HelloWorld"
                  address="http://localhost:8280/services/HelloWorld" />
</beans>
package com.example.demo;

import com.example.demo.ws.service.HelloWorld;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import javax.xml.datatype.XMLGregorianCalendar;

public class Main {

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        HelloWorld client = (HelloWorld) context.getBean("helloClient");

        String resp1 = client.sayHi("小明");
        System.out.println(resp1);
        XMLGregorianCalendar resp2 = client.currentDate();
        System.out.println(resp2.toString());
    }
}
不使用 spring
package com.example.demo;

import com.example.demo.ws.service.HelloWorld;

import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import java.net.MalformedURLException;
import java.net.URL;

public class WithoutSpring {
    public static void main(String[] args) throws MalformedURLException {
        URL wsdlURL = new URL("http://localhost:8280/services/HelloWorld?wsdl");
        QName SERVICE_NAME = new QName("http://service.ws.demo.example.com/", "HelloWorldImplService");
        Service service = Service.create(wsdlURL, SERVICE_NAME);
        HelloWorld client = service.getPort(HelloWorld.class);
        String result = client.sayHi("小红");
        System.out.println(result);
    }
}

可以直接运行的demo

其他配置

demo 中是比较简单的情况,但是实际的情况会更复杂,下面介绍一下常用的配置

SSL Certificate and Proxy

参考 https://cxf.apache.org/docs/c...

在 applicationContext.xml 可以为web service client 配置proxy 和 ssl cert,完全不用写代码。

ssl 证书有两种形式 pkcs12、jks, 指定路径有三种形式 url、file、resource

cxf-codegen-plugin

cxf 的 maven 插件可以指定参数来解决一下常见的问题(<extraargs>下的<extraarg>可以选择所需的wsdl2java命令参数使用)

参考 http://cxf.apache.org/docs/ws...

  • 添加-autoNameResolution 解决wsdl中命名冲突
  • 添加-p packagename 指定自动生成的包名
      <plugin>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-codegen-plugin</artifactId>
        <version>3.2.2</version>

            <configuration>
