Question

我是网络服务新手。经过大量的谷歌搜索并尝试了有关从端点访问SoapHeader的所有内容，我仍然无法让它工作。我收到以下错误：

java.lang.IllegalStateException：添加时没有端点适配器 SoapHeader在处理方法的方法签名中。

如果删除SoapHeader参数，我没有任何问题。

端点类：

package endpoints;

import javax.annotation.Resource;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ws.server.endpoint.annotation.Endpoint;

@Endpoint
public class PostBackServiceEndpoint {
    private static final String TARGET_NAMESPACE = 
        "http://services/cfPostBack/2015/";

    @Resource(name="postBackService")

    @Autowired                                                                             
    public PostBackServiceEndpoint(PostBackService postBackService) {
        this.postBackService = postBackService;
    }

    @PayloadRoot(localPart = "postBackRequest", namespace = TARGET_NAMESPACE)
    @ResponsePayload
    public PostBackResponseDocument getPostBackResponse(
        @RequestPayload PostBackRequestDocument request, SoapHeader soapHeader) 
        throws Exception {

        PostBackResponseDocument response = 
            postBackService.processPostBackRequest(request);

        return response;
    }

    public void setPostBackService(PostBackService postBackService) {
        this.postBackService = postBackService;
    }
}

Answer 1

您可能需要将org.springframework.ws.soap.server.endpoint.adapter.method.SoapMethodArgumentResolver bean添加到methodArgumentResolvers列表中。

Answer 2

实际上，安德烈亚斯，你是对的。将SoapMethodArgumentResolver bean添加到methodArgumentResolvers列表确实有效。我试图访问端点中的MessageContext而不是SoapHeader。对于MessageContext，我添加了MessageContextMethodArgumentResolver。

仍然无法从端点访问SoapHeader
