当我启动spring应用程序时,我收到错误并且Tomcat服务器无法启动。 这是我下面的工作(在主应用程序中,阅读部分和hibernate部分工作正常)

答案 0 :(得分:1)
根据日志,您需要创建DataSource bean以连接到您正在使用的数据库。例如。在配置中的某个位置,您需要定义数据源bean:
@Bean
public DataSource dataSource() {
...
}
答案 1 :(得分:0)
您尚未声明任何DataSource
。您有两种选择:
配置您自己的DataSource
,例如如下()。
@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;
};
