java - Perl 客户端到 JAX-WS java 服务器问题

Question

我有一个发布 Web 服务的 JAX-WS java 服务器

@WebService(endpointInterface="calculator.operation.Calculator")
public class CalculatorWs implements Calculator{

public String[] add(String a) {

    System.out.println(a);

    String[] test = {"this", "that"};
    System.out.println(test);
    return test;
}

}

和

@WebService
@SOAPBinding(style=SOAPBinding.Style.DOCUMENT)
public interface Calculator {
    String[] add(String a);
}

并且有一个 perl 客户端

use SOAP::Lite +trace => 'all';
$SOAP::Constants::PREFIX_ENV = 'soapenv';
$SOAP::Constants::PREFIX_ENC = "SOAP-ENC";
my $soap = SOAP::Lite
->service('http://localhost:8080/tomcat/calculator?wsdl')
->soapversion('1.1');
my $var = {'a' => "test"};
my $result = $soap -> add($var);

我遇到的问题是，尽管客户端接收并识别了 Java 服务器返回的值，但 Java 服务器没有接收 Perl 客户端传递的参数。

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsp="http://www.w3.org/ns/ws-policy" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsam="http://www.w3.org/2
007/05/addressing/metadata" xmlns:wsp1_2="http://schemas.xmlsoap.org/ws/2004/09/
policy" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="ht
tp://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://operation.calculator/
" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soapenv:Body><tns:add><c-gensym3
><a xsi:type="xsd:string">test</a></c-gensym3></tns:add></soapenv:Body></soapenv
:Envelope>

这是 Perl 客户端发送的 SOAP 请求。我认为这应该归咎于其构建 SOAP 请求的方式。但如果有人能帮助我解决这个问题，我将不胜感激。谢谢。

(编辑)下面是 JAX-WS 生成的 WSDL:

显示 java 函数对于 java 程序员来说非常有用，您需要显示 WSDL 或示例 SOAP(读取 XML)调用...我猜，您需要的一切

my $result = $soap -> add( 'test');

您应该知道 SOAP::Simple 在 wsdl 方面比 SOAP::Lite 更好
