WebService接口调用（CXF框架）

maven中添加cxf依赖：

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>3.4.4</version>
</dependency>

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-transports-http</artifactId>
    <version>3.4.4</version>
</dependency>

下载生成工具并解压：http://cxf.apache.org/download.html

版本请与依赖保持一直。

IDEA设置：

File -> Setting -> Tools -> Web Service设置CXF为生成工具根路径，如：C:\DevKit\apache-cxf-3.4.4

IDEA Project窗口选中要生成的包，工具栏点击Tools -> WebService -> Generate Java Code From Wsdl

填入WSDL地址、输出路径，Service Platform选择CXF，确定生成。

PS：IDEA 2019版本存在bug，没有Generate Java Code From Wsdl菜单，详见此文章或更换IDEA版本。

追加Header认证

首先添加自定义Header处理类：

static class ClientAuthInterceptor extends AbstractPhaseInterceptor<SoapMessage> {
    /**
    * 认证头格式：
    *    <tns:RequestSOAPHeader xmlns:tns="http://sys.webservice.client">
    *            <tns:user>user</tns:user>
    *            <tns:password>password</tns:password>
    *    </tns:RequestSOAPHeader>
    */

    private static final String USER = "user";
    private static final String PASSWORD = "password";

    public ClientAuthInterceptor() {
        super(Phase.PREPARE_SEND);
    }

    @Override
    public void handleMessage(SoapMessage message) throws Fault {
        List<Header> headers = message.getHeaders();
        Document doc = DOMUtils.createDocument();

        Element header = doc.createElement("tns:RequestSOAPHeader");
        header.setAttribute("xmlns:tns", "http://sys.webservice.client");

        Element user = doc.createElement("tns:user");
        user.setTextContent(USER);
        Element password = doc.createElement("tns:password");
        password.setTextContent(PASSWORD);

        header.appendChild(user);
        header.appendChild(password);
        headers.add(new Header(new QName(""), header));
    }
}

添加自定义Header处理器：

// 这两行是工具生成出来的接口
ISysNotifyTodoWebServiceService ss = new ISysNotifyTodoWebServiceService(wsdlURL, SERVICE_NAME);
ISysNotifyTodoWebService port = ss.getISysNotifyTodoWebServicePort();

// 创建接口时添加自定义Header处理器
Client client = ClientProxy.getClient(port);
client.getOutInterceptors().add(new ClientAuthInterceptor());
