Spring 应用程序运行失败

Question

嘿，我遇到了这个错误，我无法解决，谢谢你的帮助

ERROR 7924 --- [main] o.s.boot.SpringApplication : 应用程序运行失败

在类路径资源中定义名称为“dataSourceScriptDatabaseInitializer”的 bean 创建时出错

这是我的 pom.xml

还有我的 application.properties：

# mySQL configuration
spring.datasource.url=jbdc:mysql://localhost:3306/employeemanager
spring.datasource.username=root 
spring.datasource.password=letmein 
spring.jpa.show-sql=true 
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Answer 1

我记得，我在集成过程中遇到了类似的问题。

请您验证您的 pom.xml 和 application.properties/application.yaml 配置，如下所示。

示例 - Maven Pom.xml 4.0.0

    <groupId>com.example</groupId>
    <artifactId>spring-boot-security-oauth2</artifactId>

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.4</version>
    </parent>

    <dependencies>
        <dependency>

            </plugin>
        </plugins>
    </build>
</project>

应用程序属性 - application.yaml

spring:
 datasource:
  url: jdbc:mysql://localhost:3306/bootdb
  username: root
  password: admin
 jpa: 
  hibernate.ddl-auto: update
  show-sql: true
 user.datasource.driver-class-name: com.mysql.jdbc.Driver

有关更多详细信息，您可以查看以下工作示例：

2. https://thebasictechinfo.com/java-8/spring-boot-spring-security-with-database-authentication-mysql-rest-api-example/

另外，您能否尝试以下属性。

spring.datasource.jdbcUrl=jdbc:mysql://localhost/bootdb?useSSL=false
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

享受:)

Answer 2

# mySQL configuration
spring.datasource.url=jbdc:mysql://localhost:3306/employeemanager

有一个错字，应该是 jdbc 而不是 jbdc

Answer 3

在 Spring Boot 2.5.X 上，data.sql 脚本现在在 Hibernate 初始化之前运行。如果您想使用 data.sql 填充 Hibernate 创建的架构，请尝试将以下内容添加到您的 application.properties spring.jpa.defer-datasource-initialization=true。
