我一直在使用嵌入式服务器(使用 spring boot 应用程序运行)和添加到类路径的外部 jar(数据库驱动程序 Postgis)在 Spring boot 1.2 上很好地工作。但是当我尝试在 eclipse 中的 TomCat 8 上部署和运行它时。我收到此错误 Cannot load driver class: org.postgis.DriverWrapper
请帮忙

最佳答案
如果您在构建类路径中有该库，并不意味着您在运行应用程序的类路径中也有它。一种方法(从我的角度来看是更好的方法)是 geogeek 描述的并将库打包到 war 文件的方法。另一种方法是将 jar 库复制到 Tomcat 的/lib 文件夹中。
希望对您有所帮助!
