使用 SpringBoot Hibernate 和 Maven 的 Oracle 数据库连接错误答案

【问题标题】：Oracle Database connection error using SpringBoot Hibernate and Maven使用 SpringBoot Hibernate 和 Maven 的 Oracle 数据库连接错误
【发布时间】：2019-03-01 19:22:01
【问题描述】：

我是 maven 新手，我在我的项目中使用 SpringBoot 和 Hibernate。现在，当我尝试使用以下 maven 依赖项连接 Oracle 数据库时

<dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc</artifactId>
        <version>11.2.0</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/lib/ojdbc6-11.2.0.3.jar</systemPath>
    </dependency>

而连接Oracle db的java代码是

public class HibernateConfig {

    @Autowired
    Environment environment;

        @Bean(name = "dataSource")
        public DataSource getDataSource() {
            DataSource dataSource = DataSourceBuilder
                    .create()
                    .username("ALERTTEST")
                    .password("ALERTTEST")
                    .url("jdbc:oracle:thin:@192.168.0.198:1521:FCUBS")  
                    .driverClassName("org.hibernate.dialect.Oracle9iDialect")
                    .build();
            return dataSource;
        }
}

【问题讨论】：

您是否校对过您的问题？请更正错误（提示：部分代码在普通文本中）。

标签： hibernate maven spring-boot

【解决方案1】：

驱动类名错误。请改成“oracle.jdbc.OracleDriver”

DataSource dataSource = DataSourceBuilder
                .create()
                .username("ALERTTEST")
                .password("ALERTTEST")
                .url("jdbc:oracle:thin:@192.168.0.198:1521:FCUBS")  
                .driverClassName("oracle.jdbc.OracleDriver")
                .build();

【讨论】：

感谢您抽出宝贵时间 Vaibhav，现在错误已经消失。我没有使用“oracle.jdbc.OracleDriver”，而是使用“oracle.jdbc.driver.OracleDriver”。

【解决方案2】：

我使用类似的设置，这就是我声明数据源的方式

@PropertySource({ "classpath:application-example.properties"})
@EntityScan(basePackages = "com.org")

public class YourProjectLauncher extends SpringBootServletInitializer {

@Value("${your.db.url}")
private transient String dataSourceUrl;

@Value("${your.db.username}")
private transient String userName;

@Value("${your.db.password}")
private transient String password;

@Value("${your.db.driver-class-name}")
private transient String driverClass;

public static void main(String... args) {

    SpringApplication.run(YourProjectLauncher.class, args);
}

@Override
protected SpringApplicationBuilder configure(
        SpringApplicationBuilder application) {
    return application.sources(YourProjectLauncher.class);
}

@Bean(name = "dataSource")
@Primary
@ConfigurationProperties(prefix = "spring.datasource")
public OracleDataSource oracleDataSource() throws SQLException {
    OracleDataSource dataSource = new OracleDataSource();
    dataSource.setUser(userName);
    dataSource.setPassword(password);
    dataSource.setURL(dataSourceUrl);
    dataSource.setImplicitCachingEnabled(true);
    dataSource.setFastConnectionFailoverEnabled(true);
    dataSource.setDriverType(driverClass);

    return dataSource;
}

在属性文件中，我有如下条目

your.db.url=jdbc:oracle:thin:@//example.com:1521/YOURSIDNAME
your.db.username=yourusername
your.db.password=yourpassword
your.db.driver-class-name=oracle.jdbc.OracleDriver

希望这会有所帮助，如果您仍然遇到问题，请告诉我。
