Question

在JHipster中向实体添加字段时，最后一步（使用MySQL时）正在运行

./ mvnw编译liquibase：diff

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

的文档

但是，这对我相当简单的安装不起作用，因为该进程不使用正确的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从哪里获得证书？

下面你可以看到输出。

首先出现使用正确的设置。我的数据库被称为“imicloud”，但后来错误是：

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

显然我使用的是MySQL密码。

如何解决这个问题？

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

mvn liquibase命令使用的凭据可在liquibase插件的配置标记中的pom.xml中找到。 pom.xml的部分如下所示：

        <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 Boot属性

使用这样的数据库URL添加结尾。

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