基于jws的webservice客户端调用方法时出现中文乱码

中文乱码通常是由于字符编码不一致导致的。解决方法如下：

1. 在客户端中设置字符编码为UTF-8（或与服务端相同的编码），例如：

String encoding = "UTF-8";
BindingProvider provider = (BindingProvider) port;
Map<String, Object> requestContext = provider.getRequestContext();
requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpoint);
requestContext.put(BindingProvider.USERNAME_PROPERTY, username);
requestContext.put(BindingProvider.PASSWORD_PROPERTY, password);
requestContext.put(BindingProvider.SESSION_MAINTAIN_PROPERTY, true);
requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
requestContext.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, 3000);
requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_RESPONSE_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_CLIENT_ALLOW_CHUNKING, true);
requestContext.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
requestContext.put(JAXWSProperties.CONNECT_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.REQUEST_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_RESPONSE_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_CLIENT_ALLOW_CHUNKING, true);
requestContext.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, 3000);
requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_RESPONSE_TIMEOUT, 3000);
requestContext.put(JAXWSProperties.HTTP_CLIENT_ALLOW_CHUNKING, true);
requestContext.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192);
//设置字符编码
requestContext.put(BindingProviderProperties.ENCODING, encoding);

2. 在服务端中设置字符编码为UTF-8（或与客户端相同的编码），例如：

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns:tns="http://localhost:8080/HelloWorld"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             targetNamespace="http://localhost:8080/HelloWorld">
    <types>
        <xsd:schema>
            <xsd:import namespace="http://localhost:8080/HelloWorld"
                        schemaLocation="http://localhost:8080/HelloWorld?xsd=1"/>
        </xsd:schema>
    </types>
    <message name="sayHello">
        <part name="name" type="xsd:string"/>
    </message>
    <message name="sayHelloResponse">
        <part name="return" type="xsd:string"/>
    </message>
    <portType name="HelloWorld">
        <operation name="sayHello">
            <input message="tns:sayHello"/>
            <output message="tns:sayHelloResponse"/>
        </operation>
    </portType>
    <binding name="HelloWorldSoapBinding" type="tns:HelloWorld">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
        <operation name="sayHello">
            <soap:operation soapAction=""/>
            <input>
                <soap:body use="literal"/>
            </input>
            <output>
                <soap:body use="literal"/>
            </output>
        </operation>
    </binding>
    <service name="HelloWorldService">
        <port name="HelloWorldPort" binding="tns:HelloWorldSoapBinding">
            <soap:address location="http://localhost:8080/HelloWorld"/>
        </port>
    </service>
</definitions>

在这个例子中，我们在WSDL文件头部设置了编码为UTF-8，并在SOAP消息的body元素中使用了use="literal"来指定使用XML文本格式。这样可以确保服务端和客户端使用相同的字符编码，避免中文乱码问题。
