Spring Boot - MySQL 设置不起作用

Question

我正在尝试使用 Spring Boot 和 MySQL 开发应用程序。正如文档所说，首先我使用Intelij Idea使用Spring initializr创建了项目，配置了application.properties文件，并编写了schema-mysql.sql文件和data-mysql.sql文件。跑完项目，发现MySQL数据库中没有表，也没有数据。我的配置有什么问题？请帮忙。

application.properties 文件，

spring.datasource.url=jdbc:mysql://localhost:3306/testdb?useSSL=false
spring.datasource.username=root
spring.datasource.password=password

spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql = true
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

spring.datasource.schema=schema-mysql.sql
spring.datasource.data=data-mysql.sql

pom.xml 文件中的依赖项，

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

schema-mysql.sql 文件，

CREATE TABLE IF NOT EXISTS `SOL16_USERS` (
  `USERNAME` VARCHAR(200) NOT NULL,
  'PASSWORD' VARCHAR(200) NOT NULL,
  PRIMARY KEY (`USERNAME`)
);

CREATE TABLE IF NOT EXISTS 'SOL16_PRIVILEGES' (
  'PRIVILEGE_ID' INT(2)      NOT NULL,
  'PRIVILEGE'    VARCHAR(15) NOT NULL,
  PRIMARY KEY ('PRIVILEGE_ID')
);

CREATE TABLE IF NOT EXISTS 'SOL16_USER_PRIVILEGES' (
  'USERNAME'     VARCHAR(200) NOT NULL,
  'PRIVILEGE_ID' VARCHAR(2)   NOT NULL,
  PRIMARY KEY ('USERNAME')
);

文件/目录结构是，

src
|----main
|    |----java
|    |----resources
|    |    |----static
|    |    |----templates
|    |    |----application.properties
|    |    |----data-mysql.sql
|    |    |----schema-mysql.sql

Answer 1

随着春天的启动文件中提到的，有固定我的问题是增加spring.datasource.platform的application.properties。这就是我使用schema-{platform}.sqland初始化架构时所缺少的data-{platform}.sql。

{平台} = 价值 spring.datasource.platform

所以我的最终 application.properties 文件是，

spring.datasource.url = jdbc:mysql://localhost:3306/testdb?useSSL=false
spring.datasource.username = root
spring.datasource.password = password

spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto = validate
spring.jpa.show-sql = true
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

spring.datasource.platform=mysql
spring.datasource.schema=schema-mysql.sql
spring.datasource.data=data-mysql.sql
spring.datasource.initialize=true
spring.datasource.continue-on-error=true
