如何在Spring Boot中以默认模式以编程方式配置Oracle DataSource？

@Bean
public DataSource getDataSource() throws SQLException {
    OracleDataSource d = new OracleDataSource();
    d.setURL(Secrets.get("DB_URL"));
    d.setUser(Secrets.get("DB_USER"));
    d.setPassword(Secrets.get("DB_PASS"));
    // d.setSchema(System.getenv("DB_SCHEMA")); ???
    return d;
}

Answer 1

您无法在OracleDataSource或使用连接URL中更改架构，需要执行

ALTER SESSION SET CURRENT_SCHEMA=targetschema;

声明，如this answer中所述。根据{{3}}，初始模式没有驱动程序属性。

Answer 2

尝试将sql执行添加到数据源创建方法中

@Bean
public DataSource getDataSource() throws SQLException {
    OracleDataSource d = new OracleDataSource();
    d.setURL(Secrets.get("DB_URL"));
    d.setUser(Secrets.get("DB_USER"));
    d.setPassword(Secrets.get("DB_PASS"));

    Resource initSchema = new ClassPathResource("scripts/schema-alter.sql");
    DatabasePopulator databasePopulator = new ResourceDatabasePopulator(initSchema);
    DatabasePopulatorUtils.execute(databasePopulator, dataSource);

    return d;
}

在scripts / schema-alter.sql中将是此代码

ALTER SESSION SET CURRENT_SCHEMA=targetschema;

Answer 3

完整示例：

@Bean
public DataSource getDataSource() throws SQLException {
    OracleDataSource oracleDs = new OracleDataSource();
    oracleDs.setURL(Secrets.get("DB_URL"));
    oracleDs.setUser(Secrets.get("DB_USER"));
    oracleDs.setPassword(Secrets.get("DB_PASS"));
    // other Oracle related settings...

    HikariDataSource hikariDs = new HikariDataSource();
    hikariDs.setDataSource(oracleDs);
    hikariDs.setConnectionInitSql("ALTER SESSION SET CURRENT_SCHEMA = MY_SCHEMA");

    return hikariDs;
}

Answer 4

在Spring Boot 2中，可以在application.properties文件中使用以下属性设置所需的模式：

spring.datasource.hikari.connection-init-sql=ALTER SESSION SET CURRENT_SCHEMA = MY_SCHEMA

HikariCP是Spring Boot 2中的默认连接池。要在日志文件中查看所有HikariCP设置（包括“ connectionInitSql”），请在application.properties中添加以下内容：

logging.level.com.zaxxer.hikari=DEBUG

使用默认架构在Spring Boot中以编程方式配置OracleDataSource
