I have two Maven projects called "common" & "member". I put my MySQL connection config file(application.properties) in common project.

spring.datasource.url=jdbc:mysql://localhost:3306/train?serverTimezone=Asia/Shanghai&characterEncoding=UTF8
spring.datasource.username=train
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

And I put "common" Maven dependency in "member" project, but when I started "member" project, it can't read application.properties in "common" project. So it appears:

37.677 WARN  o.s.b.w.s.c.AnnotationConfigServletWebServerApplicationContext:592  restartedMain                    Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

I'm sure something necessary have already add in "common" & "member":

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

So, how my "member" can't read the application.properties in "common"?

  • In your member project, do you have another application.properties? Honestly I am not sure if Spring Boot is going to load application.properties from dependencies or is loading only from the application jar itself – Adrian Shum Jul 19 '23 at 07:24
