Java org.springframework.beans.factory.BeanCreationException：

伙计们，当我启动我的spring应用程序时，我得到一个错误，Tomcat服务器没有启动。 下面是我在主应用程序中的工作，阅读部分和休眠部分工作正常

根据日志，您需要创建数据源bean来连接到您正在使用的数据库。例如，在您的配置中，您需要定义数据源bean：

@Bean
public DataSource dataSource() {
    ...
}

您尚未声明任何数据源。您有两个选择：

使用 配置您自己的数据源，例如，如下所示

@Bean
public DataSource dataSource(){
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("org.hsqldb.jdbcDriver");
    dataSource.setUrl("jdbc:hsqldb:hsql://localhost:");
    dataSource.setUsername("sa");
    dataSource.setPassword("");

    return dataSource;
};

@Bean
public DataSource dataSource() {
    ...
}

@Bean
public DataSource dataSource(){
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("org.hsqldb.jdbcDriver");
    dataSource.setUrl("jdbc:hsqldb:hsql://localhost:");
    dataSource.setUsername("sa");
    dataSource.setPassword("");

    return dataSource;
};
