SpringBoot集成SAP的過程及本地IDEA啟動和Windows服務(wù)器部署

更新時間：2025年07月17日 15:01:41 作者：乘風(fēng)!

本文給大家介紹SpringBoot集成SAP的過程及本地IDEA啟動和Windows服務(wù)器部署的相關(guān)知識,本文給大家介紹的詳細,對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友參考下吧

網(wǎng)上有關(guān)Springboot集成SAP有各種各樣的說法，我這里提供一個我調(diào)通的方案。如下pom配置，sapjco3.dll 放在"%JAVA_HOME%\bin\",否則報nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.sap.conn.jco.JCo，服務(wù)器部署時也是這樣放置，

sapjco3.dll和sapjco3.jar放在resources\lib下
