Java 使用rfc调用sap函数

1. 首先准备 sapjco3.jar sapjco3.dll两个文件
2. 链接sap 创建 JcoDestination对象

public static JCoDestination getJcoDestination(SapConnInfo sapConnInfo, String destinationName) throws IOException, JCoException {
        Properties properties = new Properties();
        properties.setProperty(DestinationDataProvider.JCO_USER, sapConnInfo.getJcoUser()); // SAP连接名
        properties.setProperty(DestinationDataProvider.JCO_PASSWD, sapConnInfo.getJcoPassword());// 连接密码
        properties.setProperty(DestinationDataProvider.JCO_LANG, sapConnInfo.getJcoLang());// 语言"ZF"
        properties.setProperty(DestinationDataProvider.JCO_CLIENT, sapConnInfo.getJcoClient());// 集团号
        properties.setProperty(DestinationDataProvider.JCO_SYSNR, sapConnInfo.getJcoSysnr());// 系统编号，默认写00 "00"
        properties.setProperty(DestinationDataProvider.JCO_ASHOST, sapConnInfo.getJcoAshost());// SAP服务器地址"10.134.28.98"
//        String name = "ABAP_AS_BOOL";
        String fileName = destinationName;
        File cfg = new File(fileName + ".jcoDestination");
        if (cfg.exists()) {
            cfg.deleteOnExit();
        }else {
            FileOutputStream fos = new FileOutputStream(cfg, false);
            properties.store(fos, "create file");
        }

        return JCoDestinationManager.getDestination(fileName);
    }

3.调用sap 函数

JCoDestination jCoDestination = DbConnection.getJcoDestination(sapConnInfo, destinationName);
//sap 方法返回的table名
String resultTableName = "ZPOGR";
//创建 JCoFunction对象
JCoFunction jCoFunction = jCoDestination.getRepository()
                        .getFunctionTemplate("ZRFC_CTBS_CFA_POGR_01").getFunction();
//配置函数执行参数
JCoParameterList param = jCoFunction.getImportParameterList();
param.setValue("BSI011", dec.getBsi011());
param.setValue("BSI02", dec.getBsi02());
//调用sap 函数
jCoFunction.execute(jCoDestination);
//获取sap 函数返回的JcoTable
JCoTable jCoTable = jCoFunction.getTableParameterList().getTable(resultTableName);
//然后可以遍历JcoTable获取需要的值
