java - 如何修复Java异常 "SQLSyntaxErrorException: Table ' x.y'不存在”

Question

我正在构建一个在线购物应用程序。在我添加支付模型、支付资源、支付服务、支付存储库之前，该应用程序运行良好。我尝试在创建支付模型后删除整个数据库，但仍然不起作用。我不知道似乎有什么问题。

Answer 1

您的错误清楚地表明您尚未创建数据库表:shopdb. payment。

因此，您的持久性流程会中断(错误:使用实体管理器创建 bean 与之相关)。

如果您不想为自动生成表进行任何配置，请手动创建，但如果您动态执行此操作，

运行时未创建数据库表有以下几个原因:

1. 自动配置无法正常工作。添加注解(给定的或spring提供的其他)，

@EnableAutoConfiguration

@PropertySource

@EntityScan

数据库配置和自动创建语句未正确放置在 application.configuration/application.yml 文件中。

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect

spring.jpa.generate-ddl=true

spring.jpa.hibernate.ddl-auto=create

spring.datasource.driverClassName=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/shopdb

spring.datasource.username=database_username

spring.datasource.password=database_password

在某些情况下，您需要创建数据库的默认架构。

在某些情况下，区分大小写会在您进行此类 Activity 时发挥理想的作用，

• 我强烈建议定义 @Table、@Column 注释或 Lombok 类型的库(如果您的版本支持)。

• 根据您的要求检查您的列名称(与错误无关)。

还要验证您的映射是否存在、放置并在私有(private)上下文中正常工作。
