soap-ws獲取ws中的所有的接口方法

soap-ws獲取wsdl中的所有的接口方法

示例wsdl文件如下，生成的過程可以參考https://www.cnblogs.com/chenyun-/p/11502446.html：

<definitions xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsp="http://www.w3.org/ns/ws-policy" xmlns:wsp1_2="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.chenyun.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://impl.chenyun.com/" name="WsImplService">

<xsd:import namespace="http://impl.chenyun.com/" schemaLocation="http://localhost:8081/Webservice?xsd=1"/>
</xsd:schema>
</types>
<message name="sayname2">

</message>
<message name="sayname2Response">

<message name="sayname">

</message>
<message name="saynameResponse">

</message>
<portType name="WsImpl">

<output wsam:Action="http://impl.chenyun.com/WsImpl/sayname2Response" message="tns:sayname2Response"/>
</operation>
<operation name="sayname">
<input wsam:Action="http://impl.chenyun.com/WsImpl/saynameRequest" message="tns:sayname"/>
<output wsam:Action="http://impl.chenyun.com/WsImpl/saynameResponse" message="tns:saynameResponse"/>
</operation>
</portType>
<binding name="WsImplPortBinding" type="tns:WsImpl">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="sayname2">
<soap:operation soapAction=""/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>
<operation name="sayname">

<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>
</binding>
<service name="WsImplService">
<port name="WsImplPort" binding="tns:WsImplPortBinding">
<soap:address location="http://localhost:8081/Webservice"/>
</port>
</service>
</definitions>

通過wsdl地址獲取的所有方法，也就是operations，在wsdl文件中定義這些operation的地方是有兩處，一處在portType節點，一處是在binding節點處，兩處均可以獲取到所有的方法，具體有什么差別暫時還沒有發現，這里使用的是在binding節點處獲取，在portType處獲取暫時沒有測試，后續可能會更新。

在Readme中可以找到Quick-start，根據里面的講解，我們需要使用的部分需要添加一個依賴和一個倉庫(添加倉庫是因為還沒有添加進maven的核心倉庫，文檔中有介紹)

pom.xml

至此，准備已經大概完成，下面是介紹核心代碼：

getList.java

/*
 * @author:陳雲
 * @date：2019/9/10
 * @description:返回接口列表
 */
package com.chenyun;

import org.reficio.ws.builder.SoapBuilder;
import org.reficio.ws.builder.SoapOperation;
import org.reficio.ws.builder.core.Wsdl;

import javax.xml.namespace.QName;
import java.util.ArrayList;
import java.util.List;

public class getList {
    /**
     *
     * @param wsdlUrl
     * @return  List<String>接口列表
     */
    public static List<String> getBindingOperations(String wsdlUrl) {
        List<String> operationList = new ArrayList();
        List<SoapOperation> soapOperationList = new ArrayList();
        //解析指定的wsdl文件，生成一個wsdl對象
        Wsdl parser = Wsdl.parse(wsdlUrl);
        //類Wsdl中提供了獲取所有binding的方法getBindings()
        List<QName> bindQnames = parser.getBindings();
        //接口SoapBuilder，定義了獲取operation的方法，獲取的是binding節點的所有operation。
        for (QName qName : bindQnames) {
            SoapBuilder soapBuilder = parser.binding().localPart(qName.getLocalPart()).find();
            soapOperationList.addAll(soapBuilder.getOperations());
        }
        for (SoapOperation soapOperation : soapOperationList) {
            operationList.add(soapOperation.getOperationName());
        }
        return operationList;
    }
}

WebserviceTestV5Application.java

package com.chenyun;

import org.apache.log4j.BasicConfigurator;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import static com.chenyun.getList.getBindingOperations;

@SpringBootApplication
public class WebserviceTestV5Application {

    public static void main(String[] args) {
        SpringApplication.run(WebserviceTestV5Application.class, args);
        //提供wsdl的值，調用getBindingOperations()
        String wsdl = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl";
        System.out.println("=====================================");
        System.out.println("接口列表：");
        for(int i=0;i<getBindingOperations(wsdl).size();i++){
            System.out.println("接口" + i + ":"+ getBindingOperations(wsdl).get(i));
        }
        System.out.println("=====================================");
        System.out.println("接口查詢結束");
    }
}

運行主函數即可獲取到結果。
