无法获得驱动程序实例

标签： java spring spring-boot hsqldb hikaricp

我是Spring（Boot）的新手，并试图获得与HSQLDB服务器的池化数据库连接。

的pom.xml

myDataSource 

@Bean
@Profile("devel")
public DataSource myDataSource() {
    HikariConfig config = new HikariConfig();
    config.setJdbcUrl("org.hsqldb.jdbc.JDBCDataSource://localhost:9001/devel");
    config.setUsername("SA");
    HikariDataSource ds = new HikariDataSource(config);

当调试器到达最后一行时，它会抛出：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'myDataSource' defined in class path resource [com/pushforgo/config/AppConfigurationProd.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'myDataSource' threw exception; nested exception is java.lang.RuntimeException: Failed to get driver instance for jdbcUrl=org.hsqldb.jdbc.JDBCDataSource://localhost:9001/devel; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myDataSource' defined in class path resource [com/pushforgo/config/AppConfigurationProd.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'myDataSource' threw exception; nested exception is java.lang.RuntimeException: Failed to get driver instance for jdbcUrl=org.hsqldb.jdbc.JDBCDataSource://localhost:9001/devel

我已经检查过数据库，可以使用像Squirrel和给定的JDBC字符串这样的工具连接到数据库而没有任何问题。

修改

设置URL和driverClassName后我得到了这个

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'myDataSource' defined in class path resource [com/pushforgo/config/AppConfigurationProd.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'myDataSource' threw exception; nested exception is com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: connection exception: connection failure: java.io.EOFException; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myDataSource' defined in class path resource [com/pushforgo/config/AppConfigurationProd.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'myDataSource' threw exception; nested exception is com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: connection exception: connection failure: java.io.EOFException

3 个答案:

答案 0 :(得分：5)

您的网址似乎有误。据我记忆，它应该是：

jdbc:hsqldb:hsql://localhost:9001/devel

而且，您没有提供驱动程序类名称（org.hsqldb.jdbc.JDBCDriver）。

config.setDriverClassName("org.hsqldb.jdbc.JDBCDriver");

如果您使用的是Spring Boot 1.4，则在使用HikariCP时无需明确定义数据源。如documentation中所述。

答案 1 :(得分：1)

config.addDataSourceProperty("useSSL",false);可能有用。

答案 2 :(得分：0)

根据documentation，正确的行应为

config.setJdbcUrl("jdbc:hsqldb:hsql://localhost:9001/devel");
