Spring WS - I / O错误：null;嵌套异常是org.apache.http.client.ClientProtocolException

Question

我可以使用soap ui请求soap web服务服务器，但是在使用java时我发现了一些问题，比如ClientProtocolException，请帮助我，我不知道我的代码有什么问题，我准备好了配置代理和验证，但仍然是这样的错误，请帮助我 这是我的代码

package com.muf.ws.client;

@Configuration
public class ClientConfig {
    @Value("${client.default-uri}")
    private String defaultUri;

    @Bean
    Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath("com.creditinfo.cb5");

        return marshaller;
    }

    @Bean
    public WebServiceTemplate webServiceTemplate() {
        WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
        UsernamePasswordCredentials user = new
                UsernamePasswordCredentials("username", "pass");
        webServiceTemplate.setMarshaller(marshaller());
        webServiceTemplate.setUnmarshaller(marshaller());
        webServiceTemplate.setDefaultUri(defaultUri);
        HttpHost host = new HttpHost("proxy", port);
        HttpComponentsMessageSender messageSender = new
                HttpComponentsMessageSender();
        webServiceTemplate.setMessageSender(messageSender);

        messageSender.setHttpClient(HttpClients.custom().setProxy(host).build());
        messageSender.setCredentials(user);
        return webServiceTemplate;
    }
    ...
}

这是错误

Answer 1

您可以添加一个拦截器以删除Content-Length标头。请尝试以下操作：

HttpClients
.custom()
.setProxy(host)
.addInterceptorFirst(new HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
.build();
