配置SAP集成开发环境
windows
librfc32.dll,sapjcorfc.dll 放到c:\windows\system32下面
sapjco.jar 放到当前项目的\web-inf\lib下面
linux
librfccm.so、libsapjcorfc.so放到jdk所安装的路径下的jre/lib/amd64下面
sapjco.jar 放到当前项目的WEB-INF\lib下面
代码示例
// sap连接属性 Properties logonProperties = new Properties(); logonProperties.put("jco.client.ashost", "192.168.255.256"); logonProperties.put("jco.client.client", "800"); logonProperties.put("jco.client.sysnr", "12"); logonProperties.put("jco.client.user", "username"); logonProperties.put("jco.client.passwd", "password"); logonProperties.put("jco.client.lang", "zh"); logonProperties.put("jco.client.CodePage", "8400"); JCO.Client client = JCO.createClient(logonProperties); // 建立连接 client.connect(); // 建立repository JCO.Repository repository = new JCO.Repository("myRepository", client); // 获取函数模版 IFunctionTemplate functionTemplate = repository.getFunctionTemplate("Y_FUNCTION_NAME"); // 获取函数对象 JCO.Function function = functionTemplate.getFunction(); // 输入参数列表 JCO.ParameterList parameterList = function.getImportParameterList(); // 输入结构赋值 JCO.Structure oaidStructure = parameterList.getStructure("IS_OAID"); oaidStructure.setValue("12", "OAID"); oaidStructure.setValue("23", "MATNR"); // client 执行函数 client.execute(function); // 获取输出参数列表 ParameterList exportParameterList = function.getExportParameterList(); // 根据参数名获取参数值 System.out.println("EX_TYPE : " + exportParameterList.getString("EX_TYPE")); System.out.println("EX_MESSAGE : " + exportParameterList.getString("EX_MESSAGE")); // 获取表 ParameterList tableParameterList = function.getTableParameterList(); Table etOaid = tableParameterList.getTable("ET_OAID"); for (int i = 0; i < etOaid.getNumRows(); i++) { etOaid.setRow(i); // 设置游标 System.out.print("MANDT : " + etOaid.getString("MANDT")); System.out.print(" MATNR : " + etOaid.getString("MATNR")); System.out.print(" OAID : " + etOaid.getString("OAID")); System.out.println(" CONFX : " + etOaid.getString("CONFX")); }- 1

如图,RFC函数包括:
* 导入-输入参数(普通参数,结构)
* 导出-输出参数(普通参数,结构)
* 表-不区分导入导出,同一个表可作为导入表,也可作为导出表,甚至可以同时作为导入导出表
