JHipster

Question

在 JHipster 中向实体添加字段时，最后一步（使用 MySQL 时）是运行

./mvnw compile liquibase:diff

根据 https://jhipster.github.io/development/

上的文档

然而，这对我相当简单的安装不起作用，因为该过程没有使用正确的 MySQL 用户并通过。我的应用程序在开发配置文件中运行良好，但不是这样。

Liquibase 从哪里获得凭证？

下面你可以看到输出。

首先似乎使用了正确的设置。我的数据库名为 "imicloud"，但后来的错误是：

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: NO)

显然我正在为 MySQL 使用密码。

如何解决这个问题？

我想我错过了一个重要的设置步骤，因为这是我第一次使用 liquibase:diff 命令。

Answer 1

mvn liquibase 命令使用的凭据在您 pom.xml 的 liquibase 插件配置标签中找到。 pom.xml 的部分看起来像：

        <plugin>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-maven-plugin</artifactId>
            <version>${liquibase.version}</version>
            <configuration>
                <changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
                <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
                <driver>com.mysql.jdbc.Driver</driver>
                <url>jdbc:mysql://localhost:3306/ng2</url>
                <defaultSchemaName>ng2</defaultSchemaName>
                <username>root</username>
                <password></password>
                <referenceUrl>hibernate:spring:com.mycompany.myapp.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&amp;hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&amp;hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy</referenceUrl>
                <verbose>true</verbose>
                <logging>debug</logging>
            </configuration>
            ...

Answer 2

在 src/main/resources/config/application-.yml 或应用程序-.properties 文件

中相应地配置 Spring 启动属性

像这样用您的数据库 URL 添加结尾。

url: jdbc:mysql://localhost:3306/imicloud?u‌seSSL=false

JHipster - 运行 liquibase:diff 由于 "Access denied" 而失败

JHipster - Running liquibase:diff fails due to "Access denied"

mysql

liquibase
