java - 无法将 JDBC-Hikari 连接到我的 Micronaut 应用程序

Question

运行 sudo ./gradlew run 后出现错误:

Task :run FAILED 12:03:13.440 [main] ERROR com.zaxxer.hikari.HikariConfig - Failed to load driver class com.mysql.jdbc.Driver from HikariConfig class classloader jdk.internal.loader.ClassLoaders$AppClassLoader@3d4eac69 12:03:13.445 [main] ERROR io.micronaut.runtime.Micronaut - Error starting Micronaut server: Bean definition [javax.sql.DataSource] could not be loaded: Error instantiating bean of type [javax.sql.DataSource]

我的 Application.yml 看起来如何:

<小时/>

micronaut:
  application:
    name: freshdb2

<小时/>

#datasources.default: {}

datasources:
  default:
    url: jdbc:mysql://localhost:3306/mydb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    username: root
    password: ""
    driverClassName: com.mysql.jdbc.Driver

Answer 1

您缺少驱动程序，您应该添加依赖项mysql-connector-java，对于gradle添加:

runtime group: 'mysql', name: 'mysql-connector-java', version: '8.0.13'
