我想将spring boot app（github）部署到tomcat 8.5应用服务器（本地运行）。我正在关注this tutorial，但我收到了错误

Tomcat 8.5
这是我在tomcat服务器上的context.xml中的JNDI配置
<Resource name="jdbc/test.sqlite"
auth="Container"
type="javax.sql.DataSource"
maxActive="100"
maxIdle="30"
maxWait="10000"
driverClassName="org.sqlite.JDBC"
url="jdbc:sqlite:/${catalina.home}/databases/test.sqlite"
factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory">
</Resource>
春季启动
此处配置DataSource bean：
@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer
{
private static Class<DemoApplication> applicationClass = DemoApplication.class;
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
@Bean
public DataSource dataSource()
{
JndiObjectFactoryBean jndiObjectFB = new JndiObjectFactoryBean();
jndiObjectFB.setJndiName("jdbc/test.sqlite");
jndiObjectFB.setResourceRef(true);
jndiObjectFB.setProxyInterface(javax.sql.DataSource.class);
return (DataSource) jndiObjectFB.getObject();
}
}
DataSource
CartDao
public interface CartDao extends CrudRepository<Cart, Long> {
Cart getById(long id);
}
应用程序属性为空。

答案 0 :(得分：0)
听起来正如您所发生的那样，Spring无法实例化与数据源的连接。 可能的原因可能是：
为了进一步确定问题，我首先尝试确定为什么spring无法通过启用调试日志记录来实例化数据存储区：
