一、配置環境：?
1.下載sapjco3.dll插件置放在JDK、bin文件夾下?
2.下載sapjco3.jar置放工程中

二、配置訪問屬性文件?
SAPConnectionPool.properties

#sap服務器IP地址，如果是外網訪問，則在內網IP前加/H/外網IP/H/192.168.0.10 jco.client.ashost=192.168.0.10 #系統編號 jco.client.sysnr=01 #配置client jco.client.client=999 jco.client.user=likb jco.client.passwd=330330 jco.destination.pool_capacity=3 jco.destination.peak_limit=10 jco.client.lang=ZH

三、封裝獲取鏈接池鏈接Java類，以便接口使用時調用?
SAPConnectionPool類:

@Service("SAPConnectionPool") public class SAPConnectionPool {private static final String SAP_CONN="SAP_CONN";public static JCoDestination getSAPDestination(){try {JCoDestination dest = JCoDestinationManager.getDestination(SAP_CONN);return dest;} catch (JCoException ex) {System.out.println(ex);System.out.println("連接失敗");//重新連接return RegetJocodestination();} } /****** @author :QZC* @createDate :2015年8月27日 上午11:08:47* 函數功能描述：重新獲取JCODestination* @return*****/public static JCoDestination RegetJocodestination(){try{Properties properFile = new Properties();ClassLoader cl=Thread.currentThread().getContextClassLoader();String filePath=cl.getResource("").toString()+"SAPConnectionPool.properties";filePath=filePath.replace("file:", "");FileInputStream inputFile = new FileInputStream(filePath);properFile.load(inputFile);inputFile.close();Properties connectProperties = new Properties();connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, properFile.getProperty("jco.client.ashost"));connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, properFile.getProperty("jco.client.sysnr"));connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, properFile.getProperty("jco.client.client"));connectProperties.setProperty(DestinationDataProvider.JCO_USER, properFile.getProperty("jco.client.user"));connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, properFile.getProperty("jco.client.passwd"));connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, properFile.getProperty("jco.destination.pool_capacity"));connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT, properFile.getProperty("jco.destination.peak_limit"));connectProperties.setProperty(DestinationDataProvider.JCO_LANG, properFile.getProperty("jco.client.lang"));CustomDestinationDataProvider provider = new CustomDestinationDataProvider();provider.addDestinationProperties(SAP_CONN, connectProperties);Environment.registerDestinationDataProvider(provider);try {JCoDestination dest = JCoDestinationManager.getDestination(SAP_CONN);return dest;} catch (JCoException ex) {System.out.println(ex);System.out.println("重新連接失敗");} }catch(Exception e){e.printStackTrace();}return null; }}

獲取鏈接的輔助處理類:CustomDestinationDataProvider.java

public class CustomDestinationDataProvider implements DestinationDataProvider {private Map providers = new HashMap();@Overridepublic Properties getDestinationProperties(String destName) {if (destName == null)throw new NullPointerException("請指定目的名稱");if (providers.size() == 0)throw new IllegalStateException("請加入一個目的連接參數屬性給提供者");return (Properties)providers.get(destName);}// 沒有實現事件處理@Overridepublic boolean supportsEvents(){return false;}@Overridepublic void setDestinationDataEventListener(DestinationDataEventListener listener) {throw new UnsupportedOperationException();}public void addDestinationProperties(String destName, Properties provider) {providers.put(destName, provider);} }
