使用 Jhipster 连接到 Mysql

Question

我已经生成了一个 spring boot + angular 应用程序。使用 jdl 导入实体。与 h2 正常工作。我是新手，想使用 mysql。我在 application-dev.yml 中配置了数据源，代码如下。

datasource:
    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false
    username: name
    password:pass
h2:
    console:
        enabled: false
     hikari:
            data-source-properties:
                cachePrepStmts: true
                prepStmtCacheSize: 250
                prepStmtCacheSqlLimit: 2048
                useServerPrepStmts: true
    jpa:
        database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
    database: mysql
    show-sql: true

2) 我已使用以下代码将我的 pom 配置从 h2 更新为 mysql。

问题当我运行我的项目时出现以下错误。

编辑 git repository link

yo-rc.json 文件

Answer 1

这不是答案，但我需要比 cmets 更多的空间。

我已经使用您的 .yo-rc.json 文件和 jhipster 4.10.2 生成了一个应用程序，它工作正常。我也有 Class-Path 清单警告，但它是无害的，并且应用程序可以正常工作。

所以，我猜你没有粘贴真正的错误。 究竟是什么症状？

Answer 2

尝试新建一个jhipster应用，在创建的时候选择Mysql。这需要几分钟，您可以检查和比较。

Answer 3

通常在 application-dev.yml 中的间距在密码中被认为是这样的

你的， 数据源： 类型：com.zaxxer.hikari.HikariDataSource 网址：jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false 用户名：姓名 密码：通过 要做的是，

数据源： 类型：com.zaxxer.hikari.HikariDataSource 网址：jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false 用户名：姓名 密码：通过

去看看

Answer 4

当我尝试使用 Mysql 安装 JHipster 项目时，我遇到了同样的问题，当我更改时我的问题得到了解决

datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/blogdb?useUnicode=true&characterEncoding=utf8&useSSL=false
username: name
password:pass

到

datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/blogdb /*Removed the parameters*/
username: name
password:pass

Answer 5

如果你使用 docker 我也有同样的错误，所以将 localhost 替换为你的 docker IP

type: com.zaxxer.hikari.HikariDataSource
        url: jdbc:mysql://192.168.99.100:3306/library
        username: root
