sap-基于jco2.x的简单封装

公司引入一套基于 java 的 bpm系统，同时需要和 sap  系统集成，为了方便调用 bapi ,将 jco 做了简单的封装:

package com.hs.commUtil;import java.io.File;import java.io.FileInputStream;import java.io.InputStream;import java.util.Properties;import com.sap.mw.jco.IFunctionTemplate;import com.sap.mw.jco.IMetaData;import com.sap.mw.jco.JCO;import com.sap.mw.jco.JCO.Client;import com.sap.mw.jco.JCO.Function;import com.sap.mw.jco.JCO.Repository;import com.sap.mw.jco.JCO.Structure;import com.sap.mw.jco.JCO.Table;public class SapRfc {/** * 获取一个SAP的连接,并处于连接状态 * @return */public static Client createJcoConn(){Properties prop = new Properties();try{String currpath = new File("").getAbsolutePath()+"//plugs//SAP_HOST.jcoDestination";InputStream in = new FileInputStream(new File(currpath));if(in != null){prop.load(in);String ashost = prop.getProperty("jco.client.ashost");String clientnr = prop.getProperty("jco.client.client");String sysnr = prop.getProperty("jco.client.sysnr");String user = prop.getProperty("jco.client.user");String pwd = prop.getProperty("jco.client.passwd");String lang = prop.getProperty("jco.client.lang");//String poolCpt = prop.getProperty("jco.destination.pool_capacity");//String pealLmt = prop.getProperty("jco.destination.peak_limit");Client myConnection = JCO.createClient(clientnr, user, pwd, lang, ashost, sysnr);myConnection.connect();return myConnection;}}catch(Exception e){e.printStackTrace(System.err);}return null;}/*** * 关闭指定的 SAP 连接 * @param myConnection SAP 连接 */public static void closeJcoConn(Client myConnection){if(myConnection != null && myConnection.isAlive()){myConnection.disconnect();}}/*** * 获取SAP的对像仓库 * @param myConnection SAP连接 * @return */public static Repository getRepository(Client myConnection){Repository repository = new Repository("", myConnection);return repository;}/*** * 获取SAP的RFC函数(BAPI) * @param funName * @param myConnection * @return */public static Function getFunction(String funName,Client myConnection){Repository myRepository = getRepository(myConnection);return getFunction(funName, myRepository);}/** * 获取SAP的RFC函数(BAPI) * @param funName * @param myRepository * @return */public static Function getFunction(String funName,Repository myRepository){IFunctionTemplate template = myRepository.getFunctionTemplate(funName.toUpperCase());if (template != null) {Function fun = template.getFunction();return fun;}return null;}/** * 获取SAP的结构 * @param structureName * @param myRepository * @return */public static Structure getGeneralStructure(String structureName,Repository myRepository){IMetaData structureDefinition = myRepository.getStructureDefinition(structureName.toUpperCase());if (structureDefinition!=null){Structure myStructure = JCO.createStructure(structureDefinition);return myStructure;}return null;}/*** * 获取SAP的结构 * @param structureName * @param myConnection * @return */public static Structure getGeneralStructure(String structureName,Client myConnection){Repository myRepository = getRepository(myConnection);return getGeneralStructure(structureName,myRepository);}/*** * 获取SAP的表 * @param tableName * @param myRepository * @return */public static Table getGeneralTable(String tableName,Repository myRepository){IMetaData tableDefinition = myRepository.getTableDefinition(tableName.toUpperCase());if (tableDefinition!=null){Table myTable = JCO.createTable(tableDefinition);return myTable;}return null;}/*** * 获取SAP的表 * @param tableName * @param myConnection * @return */public static Table getGeneralTable(String tableName,Client myConnection){Repository myRepository = getRepository(myConnection);return getGeneralTable(tableName,myRepository);}/*** * 提交在这个连接上的操作 * @param myConnection */public static void commit(Client myConnection){Function fun = getFunction("BAPI_TRANSACTION_COMMIT", myConnection);if (fun!=null){myConnection.execute(fun);}}/*** * 回滚在这个连接上的操作 * @param myConnection */public static void rollback(Client myConnection){Function fun = getFunction("BAPI_TRANSACTION_ROLLBACK", myConnection);if (fun!=null){myConnection.execute(fun);}}}
