java - 使用tomcat启动服务器时创建bean时出错

Question

我在intellij上启动了一个tomcat服务器（未部署任何东西），但出现以下错误。我一直在寻找它，但是没有运气。你能帮我么？

提前谢谢了。

错误是以下之一：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.liquibase.LiquibaseAutoConfiguration$LiquibaseConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.liquibase.LiquibaseAutoConfiguration$LiquibaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Answer 1

正如@ ivan-pronin所说，您需要对类路径的依赖。例如，如果要使用H2，则将其添加到您的pom.xml文件中。

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
</dependency>

如果使用gradle，则将其添加到 build.gradle。这适用于在类路径上具有自动发现功能的可嵌入数据库。如果要使用其他数据库（例如Mysql），则必须配置application.properties或application.yml。

spring:
    datasource:
        url: jdbc:mysql://myserver:3306/mydb?autoReconnect=true&useSSL=false
        username: foo
        password: bar
        driver-class-name: com.mysql.jdbc.Driver
