(一)通过JAVA连接SAP调用接口 (sapjco3.jar在Windows和MacOS上的配置)
一、sapjoc3.jar获取
由于sap官网提供的链接需要合作公司提供账号密码，如果商用请索要正确的用户名密码下载，如果只是想做测试使用，可以使用我这里提供的链接，资源失效请及时提醒我，谢谢
密码:1u0t
密码:7zuv
密码:lafl
二、测试项目环境准备
-
新建项目
这个就不多谈了，直接上图，我这里新建了一个空的测试项目，新建lib文件夹，准备把需要用到的jar包丢进来
-
windows和macOS环境配置
- windows 直接把 sapjco3.jar sapjco3.dll sapjco3.pdb 拷贝至lib下，然后add library把他们都添加进去
- macOS 把 sapjco3.jar 和 libsapjco3.jnilib 拷贝至lib下，同样add libray添加进去，这里只需要add sapjco3.jar 即可。
WARNING: 这里很多博客讲到需要添加classpath在变量里面，这是参照了官方提供的安装方式，这里的话我们只需要将上述文件拷贝至lib文件夹下即可。
三、源码编写及测试
首先编写用来放置sap连接信息的SapConn实体类
SapConn
/** * Created by gang.xu01@hand-china.com on 2018/12/6 */public class SapConn { // SAP服务器 private String JCO_ASHOST; // SAP系统编号 private String JCO_SYSNR; // SAP集团 private String JCO_CLIENT; // SAP用户名 private String JCO_USER; // SAP密码 private String JCO_PASSWD; // SAP登录语言 private String JCO_LANG; // 最大连接数 private String JCO_POOL_CAPACITY; // 最大连接线程 private String JCO_PEAK_LIMIT; // SAP ROUTER private String JCO_SAPROUTER; public SapConn(String JCO_ASHOST, String JCO_SYSNR, String JCO_CLIENT, String JCO_USER, String JCO_PASSWD, String JCO_LANG, String JCO_POOL_CAPACITY, String JCO_PEAK_LIMIT, String JCO_SAPROUTER) { this.JCO_ASHOST = JCO_ASHOST; this.JCO_SYSNR = JCO_SYSNR; this.JCO_CLIENT = JCO_CLIENT; this.JCO_USER = JCO_USER; this.JCO_PASSWD = JCO_PASSWD; this.JCO_LANG = JCO_LANG; this.JCO_POOL_CAPACITY = JCO_POOL_CAPACITY; this.JCO_PEAK_LIMIT = JCO_PEAK_LIMIT; this.JCO_SAPROUTER = JCO_SAPROUTER; } public SapConn() {} public String getJCO_ASHOST() { return JCO_ASHOST; } public void setJCO_ASHOST(String JCO_ASHOST) { this.JCO_ASHOST = JCO_ASHOST; } public String getJCO_SYSNR() { return JCO_SYSNR; } public void setJCO_SYSNR(String JCO_SYSNR) { this.JCO_SYSNR = JCO_SYSNR; } public String getJCO_CLIENT() { return JCO_CLIENT; } public void setJCO_CLIENT(String JCO_CLIENT) { this.JCO_CLIENT = JCO_CLIENT; } public String getJCO_USER() { return JCO_USER; } public void setJCO_USER(String JCO_USER) { this.JCO_USER = JCO_USER; } public String getJCO_PASSWD() { return JCO_PASSWD; } public void setJCO_PASSWD(String JCO_PASSWD) { this.JCO_PASSWD = JCO_PASSWD; } public String getJCO_LANG() { return JCO_LANG; } public void setJCO_LANG(String JCO_LANG) { this.JCO_LANG = JCO_LANG; } public String getJCO_POOL_CAPACITY() { return JCO_POOL_CAPACITY; } public void setJCO_POOL_CAPACITY(String JCO_POOL_CAPACITY) { this.JCO_POOL_CAPACITY = JCO_POOL_CAPACITY; } public String getJCO_PEAK_LIMIT() { return JCO_PEAK_LIMIT; } public void setJCO_PEAK_LIMIT(String JCO_PEAK_LIMIT) { this.JCO_PEAK_LIMIT = JCO_PEAK_LIMIT; } public String getJCO_SAPROUTER() { return JCO_SAPROUTER; } public void setJCO_SAPROUTER(String JCO_SAPROUTER) { this.JCO_SAPROUTER = JCO_SAPROUTER; } @Override public String toString() { return "SapConn{" + "JCO_ASHOST='" + JCO_ASHOST + '\'' + ", JCO_SYSNR='" + JCO_SYSNR + '\'' + ", JCO_CLIENT='" + JCO_CLIENT + '\'' + ", JCO_USER='" + JCO_USER + '\'' + ", JCO_PASSWD='" + JCO_PASSWD + '\'' + ", JCO_LANG='" + JCO_LANG + '\'' + ", JCO_POOL_CAPACITY='" + JCO_POOL_CAPACITY + '\'' + ", JCO_PEAK_LIMIT='" + JCO_PEAK_LIMIT + '\'' + ", JCO_SAPROUTER='" + JCO_SAPROUTER + '\'' + '}'; }}
然后编写用来建立sap连接的SapConn作为连接类
编写连接类SAPConnUtils 下面是源码
/** * Created by gang.xu01@hand-china.com on 2018/12/4 */public class SAPConnUtils { private static final String ABAP_AS_POOLED = "ABAP_AS_WITH_POOL"; /** * 创建SAP接口属性文件。 * @param name ABAP管道名称 * @param suffix 属性文件后缀 * @param properties 属性文件内容 */ private static void createDataFile(String name, String suffix, Properties properties){ File cfg = new File(name+"."+suffix); if(cfg.exists()){ cfg.deleteOnExit(); } try{ FileOutputStream fos = new FileOutputStream(cfg, false); properties.store(fos, "for tests only !"); fos.close(); }catch (Exception e){ System.out.println("Create Data file fault, error msg: " + e.toString()); throw new RuntimeException("Unable to create the destination file " + cfg.getName(), e); } } /** * 初始化SAP连接 */ private static void initProperties(SapConn sapConn) { Properties connectProperties = new Properties(); // SAP服务器 connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, sapConn.getJCO_ASHOST()); // SAP系统编号 connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, sapConn.getJCO_SYSNR()); // SAP集团 connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, sapConn.getJCO_CLIENT()); // SAP用户名 connectProperties.setProperty(DestinationDataProvider.JCO_USER, sapConn.getJCO_USER()); // SAP密码 connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, sapConn.getJCO_PASSWD()); // SAP登录语言 connectProperties.setProperty(DestinationDataProvider.JCO_LANG, sapConn.getJCO_LANG()); // 最大连接数 connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, sapConn.getJCO_POOL_CAPACITY()); // 最大连接线程 connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT, sapConn.getJCO_PEAK_LIMIT()); // SAP ROUTER connectProperties.setProperty(DestinationDataProvider.JCO_SAPROUTER, sapConn.getJCO_SAPROUTER()); createDataFile(ABAP_AS_POOLED, "jcoDestination", connectProperties); } /** * 获取SAP连接 * @return SAP连接对象 */ public static JCoDestination connect(SapConn sapConn){ System.out.println("正在连接至SAP..."); JCoDestination destination = null; initProperties(sapConn); try { destination = JCoDestinationManager.getDestination(ABAP_AS_POOLED); destination.ping(); System.out.println("已成功建立sap的连接"); } catch (JCoException e) { System.out.println("Connect SAP fault, error msg: " + e.toString()); } return destination; }}
接下来编写一个简单的测试类test
/** * Created by gang.xu01@hand-china.com on 2018/12/9 */public class testCon { public static void main(String[] args) { SapConn con = new SapConn( "127.0.0.1", "123", "456", "abc", "abc", "abc", "123", "321", "123456" ); // 测试连接 SAPConnUtils.connect(con); }}
如果出现如下结果表明连接失败，请检查连接类。
此时如果调用结果如下则表明建立连接成功。
四、常见报错
- 缺少build path
这个错误是因为缺少了上述提到的文件，请按照文中提到的顺序将其加入项目中即可。
