SpringBoot发布web service接口，并使用ABAP调用web service

1、引入依赖

　　　　<!-- CXF webservice -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
            <version>3.2.5</version>
        </dependency>

关于cxf的版本，要针对不同的spring boot版本选择对应的版本，否则可能会导致容器启动失败：

spring boot的<version>1.5.6.RELEASE</version>版本，可选择cxf的<version>3.1.11</version>版本；

spring boot的<version>2.1.3.RELEASE</version>版本，可选择cxf的<version>3.2.5</version>版本；

2、编写web service接口类：CommonService.java

package com.ybin.webservice.webservice;

import com.ybin.webservice.beans.AjaxResult;
import com.ybin.webservice.po.MaterialInfo;
import com.ybin.webservice.po.SapSecurityInfo;

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

/**
 * @Author: bingy
 * @Date: 2020.11.9 23:11
 * @Version: 1.0
 * @Description:
 **/

@WebService(name = "CommonService", 　　　　　　　　　　// 暴露服务名称
        targetNamespace = "http://fabric.ribo.com/"　// 命名空间,一般是接口的包名倒序
)
public interface CommonService {
    /**
     * 测试web service
     * @param name
     * @return
     */
    @WebMethod
    @WebResult(name = "String", targetNamespace = "")
    public String sayHello(@WebParam(name = "userName") String name);

    /**
     * 获取sap物料信息
     * @param sapSecurityInfo
     * @param materialInfo
     * @return
     */
    @WebMethod(action = "putMaterialData")
    public @WebResult
    AjaxResult putMaterialData(
            @WebParam(name = "sapSecurityInfo") SapSecurityInfo sapSecurityInfo,
            @WebParam(name = "materialInfo") MaterialInfo materialInfo
    );
}

3、编写web service实现类：CommonServiceImpl.java

package com.ybin.webservice.webservice;

import com.alibaba.fastjson.JSONObject;
import com.ybin.webservice.beans.AjaxResult;
import com.ybin.webservice.po.MaterialInfo;
import com.ybin.webservice.po.SapSecurityInfo;
import com.ybin.webservice.service.MaterialService;
import com.ybin.webservice.util.LogUtils;
import org.slf4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.jws.WebService;
import javax.xml.ws.BindingType;

/**
 * @Author: bingy
 * @Date: 2020.11.9 23:27
 * @Version: 1.0
 * @Description:
 **/

@WebService(serviceName = "CommonService", 　　　　　　　　　　　　　   　     // 与接口中指定的name一致
        targetNamespace = "http://webservice.ybin.com/", 　　　　　　　　    // 与接口中的命名空间一致,一般是接口的包名倒
        endpointInterface = "com.ybin.webservice.webservice.CommonService"// 接口地址
)
@BindingType(value = "http://www.w3.org/2003/05/soap/bindings/HTTP/")
@Component
public class CommonServiceImp implements CommonService {
    Logger logger = LogUtils.getBussinessLogger();
    @Autowired
    MaterialService materialService;

    @Override
    public String sayHello(String name) {
        return "Hello , " + name;
    }

    @Override
    public AjaxResult putMaterialData(SapSecurityInfo sapSecurityInfo, MaterialInfo materialInfo) {
        logger.info("sapSecurityInfo->" + JSONObject.toJSONString(sapSecurityInfo));
        logger.info("materialInfo->" + JSONObject.toJSONString(materialInfo));
        AjaxResult ajaxResult = new AjaxResult();
        try {
            ajaxResult = materialService.saveFromWebService(sapSecurityInfo, materialInfo.getMaterialHeader());
        } catch (Exception e) {
            e.printStackTrace();
            String errMsg = e.getMessage() != null ? e.getMessage() : "操作失败";
            ajaxResult.setRetcode(AjaxResult.FAILED);
            ajaxResult.setRetmsg(errMsg);
        }
        logger.info("ajaxResult->" + JSONObject.toJSONString(ajaxResult));
        return ajaxResult;
    }
}

省略业务相关service层代码...

4、编写cxf配置类：CxfConfig.java

package com.ybin.webservice.config;

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

import javax.xml.ws.Endpoint;

/**
 * @Author: bingy
 * @Date: 2020.11.9 23:45
 * @Version: 1.0
 * @Description:
 **/

@Configuration
public class CxfConfig {

    @Autowired
    private Bus bus;
    @Autowired
    CommonService commonService;

    /**
     * JAX-WS
     **/
    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint = new EndpointImpl(bus, commonService);
        endpoint.publish("/CommonService");
        return endpoint;
    }
}

5、启动项目，查看wsdl

web service默认发布在 http://localhost:8081/services/ 路径下：

6、用soapUI测试没有问题

7、用ABAP调用web service

*&---------------------------------------------------------------------*
*& FORM fm_call_http_client
*&---------------------------------------------------------------------*
FORM fm_call_http_client.
  DATA is_zweb_config TYPE zweb_config.
SELECT SINGLE * INTO CORRESPONDING FIELDS OF is_zweb_config FROM zweb_config
    WHERE sysname = 'YBIN_SERVICE'
      AND ifname = '/services/CommonService?'.
  IF is_zweb_config IS INITIAL.
    PERFORM fm_write_log USING '[ERROR]: There is no configurtion about host and port in table [ZWEB_CONFIG]...'.
    RETURN.
  ENDIF.

  soapaction = 'http://' && is_zweb_config-host && ':' && is_zweb_config-port && is_zweb_config-ifname.
  CONDENSE soapaction NO-GAPS.
  PERFORM fm_write_log USING soapaction.

*      lv_xml = lv_xml && '</web:putMaterialData>'.
*   lv_xml = lv_xml && '</soap:Body>'.
*lv_xml = lv_xml && '</soap:Envelope>'.

*  创建http_client对象
  CALL METHOD cl_http_client=>create_by_url
    EXPORTING

  CALL METHOD http_client->request->set_header_field
    EXPORTING
      name  = 'SOAPAction'
      value = soapaction.

  CALL METHOD http_client->request->set_header_field
    EXPORTING
      name  = 'User-Agent'
      value = 'compatible; MSIE 5.0;'.

*  将此实体的HTTP主体设置为char
  CALL METHOD http_client->request->set_cdata
    EXPORTING
      data = lv_xml.

*  发送http请求
  CALL METHOD http_client->send
    EXCEPTIONS
      http_communication_failure = 1
      http_invalid_state         = 2.

*  接收http响应
  CALL METHOD http_client->receive
    EXCEPTIONS
      http_communication_failure = 1
      http_invalid_state         = 2
      http_processing_failed     = 3.

*  返回此实体的HTTP正文作为字符数据
  CLEAR lv_log.
  lv_log = http_client->response->get_cdata( ).

  CLEAR xmldata.
  xmldata = http_client->response->get_data( ).

*  关闭http连接
  CALL METHOD http_client->close.

*解析响应返回的数据
  CLEAR lt_return[].
  CALL FUNCTION 'SMUM_XML_PARSE'
    EXPORTING
      xml_input = xmldata
    TABLES
      xml_table = lt_retable
      return    = lt_return.


  PERFORM fm_write_log USING '===== 日志 ======'.
  DATA iv_log TYPE string.
  PERFORM fm_write_log USING '[RETLOG]: Returned log:'.
  WHILE lv_log NE ''.
    SPLIT lv_log AT '>' INTO iv_log lv_log.
    iv_log = iv_log && '>'.
    PERFORM fm_write_log USING iv_log.
  ENDWHILE.
PERFORM fm_write_log USING 'Http Response:'.
  LOOP AT lt_retable.
    CLEAR iv_log.

    PERFORM fm_write_log USING iv_log.
  ENDLOOP.

ENDFORM.

此处有一点，用ABAP调用web service需要在事务代码：SICF 中配置启用web service。
