Java 获取Teradata数据源的连接时发生异常

我试图在我的控制器中注入数据源，并使用我想要的连接对象（数据源）。我用的是弹簧靴 我已经编写了两个配置类，一个用于Oracle连接，另一个用于Teradata连接

对于oracle，一切正常，但对于创建teradata数据源，我无法完善任何好的示例，因此我的配置如下所示：

@Component
@Configuration
@ConfigurationProperties("application")
public class TeradataConfiguration {


@NotNull
    private String usernameTeradata;
@NotNull
private String passwordTeradata;

@NotNull
private String servernameTeradata;

@NotNull
private String charsetTeradata;

@NotNull
private String tmodeTeradata;

@NotNull
private String dsnameTeradata;

@NotNull
private String portTeradata;

@NotNull
private String timeoutTeradata;


public void setUsernameTeradata(String usernameTeradata) {
    this.usernameTeradata = usernameTeradata;
}


public void setPasswordTeradata(String passwordTeradata) {
    this.passwordTeradata = passwordTeradata;
}


public void setServernameTeradata(String servernameTeradata) {
    this.servernameTeradata = servernameTeradata;
}


public void setCharsetTeradata(String charsetTeradata) {
    this.charsetTeradata = charsetTeradata;
}


public void setTmodeTeradata(String tmodeTeradata) {
    this.tmodeTeradata = tmodeTeradata;
}


public void setDsnameTeradata(String dsnameTeradata) {
    this.dsnameTeradata = dsnameTeradata;
}


public void setPortTeradata(String portTeradata) {
    this.portTeradata = portTeradata;
}


public void setTimeoutTeradata(String timeoutTeradata) {
    this.timeoutTeradata = timeoutTeradata;
}


@Bean
DataSource teraDataSource() throws SQLException {

    TeraDataSource teraDataSource = new TeraDataSource();
    teraDataSource.setServerName(dsnameTeradata);
    teraDataSource.setuser(usernameTeradata);
    teraDataSource.setpassword(passwordTeradata);
    teraDataSource.setCharSet(charsetTeradata);
    teraDataSource.setTMODE(tmodeTeradata);
    teraDataSource.setDSName(dsnameTeradata);
    teraDataSource.setDbsPort(portTeradata);
    teraDataSource.setLoginTimeout(Integer.valueOf(timeoutTeradata));
    return teraDataSource;

}

}

在此之后，我将这个bean注入到我的控制器中，但当我执行以下操作时：

teraDataSource.getConnection();

我得到以下例外：

我能够使用Class.forName（“驱动程序名”）通过普通的jdbc连接到teradata，但面临数据源的问题

---

提前感谢

经过一些研发和Mark的帮助，我能够使配置正常工作。我张贴的解决方案，以便其他人可以受益于答案

如果您有如下teradata url:jdbc:teradata://server_name/database=database_nane，tmode=ANSI，charset=UTF8

数据源配置文件应如下所示：

@Component
@Configuration
@ConfigurationProperties("application")
public class TeradataConfiguration {

    @NotNull
    private String usernameTeradata;

    @NotNull
    private String passwordTeradata;

    @NotNull
    private String servernameTeradata;

    @NotNull
    private String charsetTeradata;

    @NotNull
    private String tmodeTeradata;

    @NotNull
    private String dsnameTeradata;

    @NotNull
    private String portTeradata;

    public void setUsernameTeradata(String usernameTeradata) {
        this.usernameTeradata = usernameTeradata;
    }


    public void setPasswordTeradata(String passwordTeradata) {
        this.passwordTeradata = passwordTeradata;
    }


    public void setServernameTeradata(String servernameTeradata) {
        this.servernameTeradata = servernameTeradata;
    }


    public void setCharsetTeradata(String charsetTeradata) {
        this.charsetTeradata = charsetTeradata;
    }


    public void setTmodeTeradata(String tmodeTeradata) {
        this.tmodeTeradata = tmodeTeradata;
    }


    public void setDsnameTeradata(String dsnameTeradata) {
        this.dsnameTeradata = dsnameTeradata;
    }


    public void setPortTeradata(String portTeradata) {
        this.portTeradata = portTeradata;
    }

    @Bean
    DataSource teraDataSource() throws SQLException {

        TeraDataSource teraDataSource = new TeraDataSource();
        //This is username
        teraDataSource.setuser(usernameTeradata);
        //This is password
        teraDataSource.setpassword(passwordTeradata);
        //Charset which could be UTF-8 or something else
        teraDataSource.setCharSet(charsetTeradata);
        //Tmode which could be ANSII or something else
        teraDataSource.setTMODE(tmodeTeradata);
        //This is your server name
        teraDataSource.setDSName(servernameTeradata);
        //This is teradata port which by default is 1025
        teraDataSource.setDbsPort(portTeradata);
        //This is your data base name
        teraDataSource.setDatabaseName(dsnameTeradata);
        return teraDataSource;

    }
}

在这之后，只需将这个bean注入到您的类中，然后执行以下操作

teraDataSource.getConnection()

---

这将为您提供teradata连接。

请发布完整的异常stacktrace；你现在张贴的东西似乎只是在StAcT迹中间的某个地方，这使得它没有信息。请修改格式：为您的属性使用代码块；很难阅读，因为您使用了引号块。@MarkRotterVeel我添加了完整的堆栈跟踪，请看一下：java.net.UnknownHostException:TEST_DB似乎表明您的连接配置有误；它尝试使用名称

TEST\u DB

连接到数据库服务器，而我认为您打算将其作为数据库名称，而不是服务器名称。您可能想查看

teradasource

的文档，看看应该如何映射属性。@MarkrotVeel感谢您指出了连接部分，也感谢我在文档中提出的建议，在测试了几个组合后，终于让代码正常工作了。这真的很有帮助，我想知道如果他们需要连接到三个不同的teradata数据库，他们会做些什么，或者使用datasourceName？

teraDataSource.getConnection()
