请教老师问题

请教老师一个 webservice+cxf 问题

ServiceConfig

package com.imooc.passbook.webservice;

import org.apache.cxf.Bus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.xml.ws.Endpoint;

@Configuration
public class CxfWebServiceConfig {

    @Autowired
    private Bus bus;

    @Autowired
    private HelloWebService helloWebService;

    /**
     *  配置cxf服务器发布，默认地址port/service/HelloWebService 路径下
     * @return Endpoint endpoint
     */
    @Bean
    public Endpoint endpoint(){

        EndpointImpl endpoint = new EndpointImpl(bus, helloWebService);
        endpoint.publish("/HelloWebService");
        return endpoint;
    }
}

Service接口

package com.imooc.passbook.webservice;

import org.springframework.stereotype.Component;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService(name = "HelloWebService", // 暴露服务名称
            targetNamespace = "http://webservice.com.imooc.passbook") // 命名空间
public interface HelloWebService {

    @WebMethod
   String hello(@WebParam(name = "id") String id);
}

Service

package com.imooc.passbook.webservice;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import javax.jws.WebService;

@WebService(name = "HelloWebService", // 暴露服务名称
        targetNamespace = "http://webservice.com.imooc.passbook",
        endpointInterface = "com.imooc.passbook.webservice.HelloWebService") // 命名空间
@Service(value = "HelloWebService")
public class HelloWebServiceImpl implements HelloWebService {

    @Autowired
    private MerchantsMapper merchantsMapper;

    @Override
    public String hello(String id) {

        Merchants merchants = merchantsMapper.SelectMerchants(id);

        return "hello webservice" + id;
    }
}

这时我在postman中请求
图片描述Content-Type：application/xml

然后成功返回为图片描述

现在我想用xml请求，但是服务端获取不到请求数据

eg：

service接口改为

package com.imooc.passbook.webservice;

import org.springframework.stereotype.Component;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;

@WebService(name = "HelloWebService", // 暴露服务名称
            targetNamespace = "http://webservice.com.imooc.passbook") // 命名空间
public interface HelloWebService {

    @WebMethod
   String hello(String id);
}

其他没动

请求改为图片描述

服务端报错

同学你好：

    我个人是没有用过 webservice+cxf 的，所以，对这个问题不是很懂。但是，看这个异常，似乎是你的请求头不对，导致 Spring 无法解析你的请求参数报错。

    

    欢迎来 QQ 群随时交流、讨论，也非常感谢同学的支持！
