要在Spring Boot应用程序中直连SAP,你可以使用SAP提供的连接库,如JCo (Java Connector)。以下是一个简化的步骤和示例代码,展示如何在Spring Boot项目中配置和使用JCo来连接SAP。
- 添加JCo库依赖到你的
pom.xml
中:
<dependency>
<groupId>com.sap.conn.jco</groupId>
<artifactId>sapjco3</artifactId>
<version>你的版本号</version>
</dependency>
- 配置JCo连接属性,通常在
application.properties
或application.yml
中:
# SAP连接配置
sap.jco.client.client=
sap.jco.client.language=EN
sap.jco.client.passwd=
sap.jco.client.user=
sap.jco.destination.host=sap_host
sap.jco.destination.client=
sap.jco.destination.sysnr=00
sap.jco.destination.sysid=SID
sap.jco.destination.user=SAP_USER
- 创建配置类来加载JCo属性并初始化连接:
import com.sap.conn.jco.ext.DestinationDataProvider;
import com.sap.conn.jco.JCoDestination;
import com.sap.conn.jco.JCoDestinationManager;
import com.sap.conn.jco.JCoException;
import com.sap.conn.jco.JCoDestination;
@Configuration
public class SapConfiguration {
@Value("${sap.jco.destination.name}")
private String destinationName;
@Bean
public DestinationDataProvider destinationDataProvider() {
return () -> {
Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "host");
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "systemNumber");
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "client");
connectProperties.setProperty(DestinationDataProvider.JCO_USER, "username");
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "password");
connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "EN");
return connectProperties;
};
}
@Bean
public JCoDestination destination() throws JCoException {
return JCoDestinationManager.getDestination(destinationName);
}
}
- 创建服务类来执行SAP RFC调用:
import com.sap.conn.jco.JCoFunction;
import com.sap.conn.jco.JCoDestination;
import com.sap.conn.jco.JCoContext;
@Service
public class SapService {
@Autowired
private JCoDestination destination;
public String executeRfc() throws Exception {
JCoFunction function = destination.getRepository().getFunction("RFC_NAME");
JCoContext.begin(destination);
try {
function.execute(destination);
// 获取输出参数
