JAVA调用SAP端接口
JAVA调用SAP端接口
1、这里我们不讲述SAP端接口的开发，sap端接口已经写好了，java端只是调用sap的接口名；
2、调用过程中所需要的包及配置文件，在“java连接sap接口包sapjco3”中可以直接下载使用。
本博文中提供两个例子：
1、检查SAP商品SN码;
2、查询SAP采购单 。
SAPConn.java即JAVA与sap连接代码
-
package com.pcmall;

-
import java.io.File;
-
import java.io.FileOutputStream;
-
import java.util.Properties;
-
-
import org.apache.log4j.Logger;

public
class SAPConn {
-
private
static
final String ABAP_AS_POOLED =
"ABAP_AS_WITH_POOL";
-
static{
-
Properties connectProperties =
new Properties();
-
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST,
"xxx.xxx.xxx.xxx");
//服务器
-
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR,
"xxx");
//系统编号
-
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT,
"xxx");
//SAP集团
-
connectProperties.setProperty(DestinationDataProvider.JCO_USER,
"xxx");
//SAP用户名
-
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD,

//密码

-
}

/**

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){
-
log.error(

-
throw
new RuntimeException(

-
}
-
}

-
/**

*/

public static JCoDestination connect(){
-
JCoDestination destination =
null;
-
try {
-
destination = JCoDestinationManager.getDestination(ABAP_AS_POOLED);
-
}
catch (JCoException e) {
-
log.error(

-
}
-
return destination;
-
}
-
private
static Logger log = Logger.getLogger(SAPConn.class);
// 初始化日志对象
-
}
检查SAP商品SN码
调用接口代码如下
-
package com.pcmall;
-
-
import com.sap.conn.jco.JCoDestination;
-
import com.sap.conn.jco.JCoFunction;
-
import com.sap.conn.jco.JCoParameterList;
-
import com.sap.conn.jco.JCoTable;
-
-
public
class CheckSnFromSAP {
-
public static void main(String[] args) {
-
JCoFunction function =
null;
-
JCoDestination destination = SAPConn.connect();
-
String result=
"";
//调用接口返回状态
-
String message=
"";
//调用接口返回信息
-
try {
-
//调用ZRFC_GET_REMAIN_SUM函数
-
function = destination.getRepository().getFunction(
"ZFMPOS_SN_CHECK");
-
JCoParameterList input = function.getImportParameterList();
-
//发出扫码仓库
-
input.setValue(
"ZSNWERKS",
"1000");
-
//发出扫码库位
-
input.setValue(
"ZSNLGORT",
"0001");
-
//采购凭证号
-
input.setValue(
"EBELN",
"1");
-
-
//获取传入表参数SN_ITEM
-
JCoTable SN_ITEM = function.getTableParameterList().getTable(
"SN_ITEM");
-
SN_ITEM.appendRow();
//增加一行
-
//给表参数中的字段赋值，此处测试，就随便传两个值进去
-
//商品编码
-
SN_ITEM.setValue(
"MATNR",
"1");
-
//商品序列号
-
SN_ITEM.setValue(
"ZSERIAL",
"1");
-
function.execute(destination);
-
result= function.getExportParameterList().getString(
"RESULT");
//调用接口返回状态
-
message= function.getExportParameterList().getString(
"MESSAGE");
//调用接口返回信息
-
System.out.println(
"调用返回状态--->"+result+
";调用返回信息--->"+message);
-
SN_ITEM.clear();
//清空本次条件，如果要继续传入值去或者还要循环，那得将之前的条件清空
-
}
catch (Exception e) {
-
e.printStackTrace();
-
}
-
}
-
}
查询SAP采购单
调用接口代码如下
-
package com.pcmall;
-
-
import com.sap.conn.jco.JCoDestination;
-
import com.sap.conn.jco.JCoFunction;
-
import com.sap.conn.jco.JCoParameterList;
-
import com.sap.conn.jco.JCoTable;
-
-
public
class GetPoFromSAP {
-
public static void main(String[] args) {
-
JCoFunction function =
null;
-
JCoDestination destination = SAPConn.connect();
-
String result=
"";
//调用接口返回状态
-
String message=
"";
//调用接口返回信息
-
try {
-
//调用ZRFC_GET_REMAIN_SUM函数
-
function = destination.getRepository().getFunction(
"ZFMPOS_PO_QUERY");
-
JCoParameterList input = function.getImportParameterList();
-
//采购凭证号
-
input.setValue(
"EBELN",
"4500004135");
-
//单据类型
-
input.setValue(
"BSART",
"TR");
-
//制单日期从
-
input.setValue(
"AEDATF",
"");
-
//制单日期到
-
input.setValue(
"AEDATT",
"");
-
//出入库标识
-
input.setValue(
"INOUT",
"I");
-
//地点库位权限值
-
input.setValue(
"AUTHORITY",
"");
-
-
function.execute(destination);
-
result= function.getExportParameterList().getString(
"RESULT");
//调用接口返回状态
-
message= function.getExportParameterList().getString(
"MESSAGE");
//调用接口返回信息
-
-
if(result.equals(
"E")){
-
System.out.println(
"调用返回状态--->"+result+
";调用返回信息--->"+message);
-
return;
-
}
else{
-
System.out.println(
"调用返回状态--->"+result+
";调用返回信息--->"+message);
-
JCoParameterList tblexport = function.getTableParameterList();
-
//JCoParameterList tblexport = function.getTableParameterList().getTable("QUERY_H");
-
String msg = tblexport.toXML();
-
System.out.println(
"调用返回表XML--->"+msg);
-
}
-
}
catch (Exception e) {
-
e.printStackTrace();
-
}
-
}
-
}
具体的XML文本内容如下，发现返回有两张表，分别为QUERY_H、QUERY_I主从表，，得到该XML内容，则JAVA端可以对此解析，得到所需要业务信息。
