您可以在项目中进行一个简单的测试，以确保类“org.postgresql.Driver”位于类路径上

try {
  Class.forName("org.postgresql.Driver");
  //on classpath
} catch(ClassNotFoundException e) {
  // not on classpath
}

您是否在pom.xml中添加了postgres依赖项

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.3-1100-jdbc41</version>
</dependency>


org.postgresql
postgresql
9.3-1100-jdbc41

您好，欢迎来到SO。请尝试提供复制错误的简明代码片段。你包含的无关信息越多，别人就越难帮助你。好吧！我放置了我的测试类。检查postgresql.jar是否在您的类路径中？jar C:\Users\Joel Victor\。M2\repository\postgresql\postgresql\9.1-901.jdbc4\postgresql-9.1-901.jdbc4.jar在类路径中找到该类，但在org.postgresql.Driver中找不到该类。您可能需要删除提供的。可以在Maven存储库中查找最新版本：

try {
  Class.forName("org.postgresql.Driver");
  //on classpath
} catch(ClassNotFoundException e) {
  // not on classpath
}
