ly3too opened a new issue #3756: URL: https://github.com/apache/incubator-dolphinscheduler/issues/3756
*For better global communication, please give priority to using English description, thx! * *Please review https://dolphinscheduler.apache.org/en-us/docs/development/issue.html when describe an issue.* **Describe the question** 1. spring-boot support mysql connection off the shelf. you don't need to install mysql driver mannually and specify the driver class. 2. spring-boot manages the dependencies' version automatically. No need to specify lots of dependency version, which may lead to version conflict **What are the current deficiencies and the benefits of improvement** 1. if you use mysql driver, just configure datasoure.properities like so: ``` # spring.datasource.driver-class-name=com.mysql.jdbc.Driver No need to specify spring.datasource.url=jdbc:mysql://host:3306/dolphinscheduler?characterEncoding=UTF-8&allowMultiQueries=true spring.datasource.username=user spring.datasource.password=pass ``` change the dependency config to ``` <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> ``` 2. import spring-boot dependencies to top pom, you can save lots of spring related depency management ``` <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>${spring.boot.version}</version> <type>pom</type> <scope>import</scope> </dependency> ``` **Which version of DolphinScheduler:** -[1.3.2-preview] **Describe alternatives you've considered** No ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
