【中文标题】没有找到适合“jdbc:oracle:thin:@****”oracle/jdbc/driver/OracleDriver”的驱动程序；

【英文标题】：No suitable driver found for "jdbc:oracle:thin:@**** "oracle/jdbc/driver/OracleDriver";

【问题描述】：

这是我的java代码

public static Map<String,String> propertyFileReader() 
    Map<String, String> map=new HashMap<String, String>();
    Properties prop = new Properties();
    try 
        InputStream inputStream = Util.class.getClassLoader().getResourceAsStream("jdbc.properties");
        prop.load(inputStream);

        final String DB_DRIVER= prop.getProperty("DB_DRIVER");
        final String DB_CONNECTION = prop.getProperty("DB_CONNECTION2");
        final String DB_USER = prop.getProperty("DB_USER");
        final String DB_PASSWORD = prop.getProperty("DB_PASSWORD");

        map.put("DB_DRIVER",DB_DRIVER);
        map.put("DB_CONNECTION",DB_CONNECTION);
        map.put("DB_USER",DB_USER);
        map.put("DB_PASSWORD",DB_PASSWORD);

     catch (IOException e) 
        e.printStackTrace();
    

    return map;


private static Connection getDBConnection() 
    Map<String , String > map=new HashMap<String, String>();
    map=propertyFileReader();
    String DB_DRIVER=map.get("DB_DRIVER");
    String DB_CONNECTION= map.get("DB_CONNECTION");
    String DB_USER=map.get("DB_USER");
    String DB_PASSWORD=map.get("DB_PASSWORD");
    Connection dbConnection = null;
    try 
        Class.forName(DB_DRIVER);
     catch (ClassNotFoundException e) 
        System.out.println(e.getMessage());
    
    try 
        dbConnection = DriverManager.getConnection(DB_CONNECTION,DB_USER,DB_PASSWORD);
        return dbConnection;
     catch (SQLException e) 
        System.out.println(e.getMessage());
    
    return dbConnection;

这是我的属性文件

DB_DRIVER = "oracle.jdbc.driver.OracleDriver";
DB_CONNECTION2 = "jdbc:oracle:thin:@10.2.5.23:1521:dbslic";
DB_USER = "TSR_MOBILE";
DB_PASSWORD = "TSR_MOBILE";

我将 ojdbc6.jar 添加到我的构建路径 [也尝试使用 ojdbc14.jar]

但有如下错误提示

No suitable driver found for "jdbc:oracle:thin:@10.2.5.23:1521:dbslic";
"oracle/jdbc/driver/OracleDriver";
No suitable driver found for "jdbc:oracle:thin:@10.2.5.23:1521:dbslic";

请帮我解决这个问题

【问题讨论】：

你将它添加到你的构建路径中，这很好地满足了编译时依赖，如果你有的话。您是否也将它打包在您的 tomcat 的 lib 文件夹中，以便在运行时使用该驱动程序？

【参考方案1】：

您使用了错误的包来引用 OracleDriver 类 改变

oracle.jdbc.driver.OracleDriver  

到

oracle.jdbc.OracleDriver  

From oracle docs类定义

public class OracleDriver
              extends oracle.jdbc.driver.OracleDriver

实现java.sql.Driver 接口的Oracle JDBC 驱动程序类。

【参考方案2】：

将其用作 Oracle 驱动程序

oracle.jdbc.OracleDriver 

而不是

oracle.jdbc.driver.OracleDriver

【参考方案3】：

这个答案“有点”晚了，但接受的答案不正确，所以我将这个答案发布给那些不幸尝试复制/粘贴代码并想知道出了什么问题的人。

接受的答案到目前为止是正确的

oracle.jdbc.driver.OracleDriver

已弃用，但在 2020 年仍然可以使用。发布代码的问题是属性文件使用了分号和引号，即not valid。所以从

更改属性文件

DB_DRIVER = "oracle.jdbc.driver.OracleDriver";
DB_CONNECTION2 = "jdbc:oracle:thin:@10.2.5.23:1521:dbslic";
DB_USER = "TSR_MOBILE";
DB_PASSWORD = "TSR_MOBILE";

到

DB_DRIVER = oracle.jdbc.driver.OracleDriver
DB_CONNECTION2 = jdbc:oracle:thin:@10.2.5.23:1521:dbslic
DB_USER = SR_MOBILE
DB_PASSWORD = TSR_MOBILE

使错误消失。
