oracle 数据源 java.sql.SQLException：字符串索引超出范围：-1 in spring

Question

我有一个 spring 引导 1.5.22 应用程序，我正在尝试使用 tomcat-jdbc 和 ojdbc6 连接到 oracle 10g。
我有连接到我的数据库的数据源 getproperties() 函数：

DataSource dataSourceProperties()  {
     DataSource ds=null;
    try {
    ds = DataSourceBuilder.create()
            .driverClassName("oracle.jdbc.OracleDriver")
            .url("jdbc:oracle:thin:@//host:port/DBname")
            .username("xxx")
            .password("xxx")
            .build();
    }catch (Exception e) {
        System.out.println(e.toString());}

当 url 使用此 SID 格式时：jdbc:oracle:thin:@host:port:DBname 我收到一个 oracle 错误：refused:ROR=(code=12505)(EMFI=4) 当我将其更改为 jdbc:oracle:thin:@host:port/DBname 我得到 java.sql.SQLException: String index out of范围：-1 最后这种格式 jdbc:oracle:thin:@//host:port/DBname 并且仍然得到 java.sql.SQLException: String index超出范围：-1

这就是我在 getConnection 函数中调用该函数的方式：

public Connection getConnection() throws SQLException
    {  
        
        Connection conn=null;
            try {
                this.ds=this.dataSourceProperties();
                conn=ds.getConnection();
            }catch (SQLException e ) {
                System.out.println(e.toString());
                
            }
            return conn;}

这里有一些错误日志：

2021-08-16 18:33:59.926 ERROR 22476 --- [bio-8080-exec-1] o.a.tomcat.jdbc.pool.ConnectionPool      : Unable to create initial connections of pool.

这是将 url 修改为正确格式后的新错误日志 jdbc:oracle:thin://xx:1509/xxx

已解决：这个对我有用:)

jdbc:oracle:thin://host:port/ServiceName

一个例子：

jdbc:oracle:thin://主机名:1509/ServiceName（或数据库名称）
