Java使用JCO實現調用SAP接口（建立采購單）

運行效果 

一、配置連接

1、在自己電腦配置Java的開發環境（ jdk、tcomcat、sapjco3），

在項目中引入sapjco3.jar包,工具包下載地址：https://mvnrepository.com/artifact/com.sap.conn.jco/sapjco3

http://maven.mit.edu/nexus/content/repositories/public/com/sap/conn/jco/sapjco3/3.0.14/

 

2、創建Java類，配置連接

import java.io.File;
import java.io.FileOutputStream;
import java.util.Properties;

import com.sap.conn.jco.JCoDestination;
import com.sap.conn.jco.JCoDestinationManager;
import com.sap.conn.jco.JCoException;
import com.sap.conn.jco.ext.DestinationDataProvider;

public class SAPConn {
    
    private static final String ABAP_AS_POOLED = "ABAP_AS_WITH_POOL";    
    static {
        Properties connectProperties = new Properties();
        connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "192.168.XXX.XX"); //服務器
        connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "00"); //系統編號
        connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "202"); //SAP環境
        connectProperties.setProperty(DestinationDataProvider.JCO_USER, "XXX"); // SAP用戶名
        connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "XXX"); // 密碼
        connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "ZF"); // 登錄語言:ZH ZF EN
        connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, "3"); // 最大連接數
        connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT, "10"); // 最大連接線程
        //connectProperties.setProperty(DestinationDataProvider.JCO_SAPROUTER, ""); //外網訪問SAP需設置此參數

        createDataFile(ABAP_AS_POOLED,"jcoDestination",connectProperties);
    }
    
    /**
     * 創建SAP接口屬性文件
     * @param name
     *             ABAP管道名稱
     * @param suffix
     *             屬性文件后綴
     * @param properties
     *             屬性文件內容
     */

    private static void createDataFile(String name, String suffix, Properties properties) {
        // TODO Auto-generated method stub
        File cfg = new File(name + "." + suffix);
        if    (cfg.exists()) {
            cfg.deleteOnExit();
        }
        try {
            FileOutputStream fos = new FileOutputStream(cfg,false);
            properties.store(fos, "for test only!");
        } catch (Exception e) {
            // TODO: handle exception
//            System.out.println("Create Data file fault,error msg:" + e.toString());
            throw new RuntimeException("無法創建目標文件" + cfg.getName());
        }
    }
    
    public static JCoDestination connect() {
        JCoDestination destination = null;
        try {
            destination = JCoDestinationManager.getDestination(ABAP_AS_POOLED);
//            System.out.println(destination.getAttributes());
        } catch (JCoException e) {
            // TODO: handle exception
//            System.out.println("連接SAP失敗，錯誤: " + e.toString());
        }
        return destination;
    }
    
}

 

二、接口調用

import com.sap.conn.jco.JCoDestination;
import com.sap.conn.jco.JCoException;
import com.sap.conn.jco.JCoFunction;

import com.sap.conn.jco.JCoRepository;
import com.sap.conn.jco.JCoStructure;
import com.sap.conn.jco.JCoTable;
import com.util.SAPConn;

public class Test2 {
    public static void main(String[] args) throws JCoException {
        
        //獲取連接
        JCoDestination destination = SAPConn.connect();
    
        //獲取接口
        JCoFunction function = destination.getRepository().getFunction("BAPI_PO_CREATE1");
        
        //Import
        
        //參數
        //function.getImportParameterList().setValue("NO_MESSAGING", "");

        //表格
        JCoTable poItemTabe = function.getTableParameterList().getTable("POITEM");
        poItemTabe.appendRow();
        poItemTabe.setValue("PO_ITEM", "10");                     //采購單項次
