sql-server - 使用 Jhipster 设置 MSSQL 时出现问题

Question

我正在尝试将 jhipster 用于我的后端项目，要求之一是使用 mssql。根据我之前的问题: https://github.com/jhipster/generator-jhipster/issues/4612#issuecomment-265076842

@ruddel 确实建议我使用这个

datasource:
        type: com.zaxxer.hikari.HikariDataSource
        url: jdbc:sqlserver://localhost:1433;database=msqltest
        username: SA
        password: yourStrong(!)Password
        hikari:
                  .........
    jpa:
        database-platform: org.hibernate.dialect.SQLServer2012Dialect
        database: SQL_SERVER
                  .........   

设置此后，我需要运行 maven 命令，以便可以按照 jhipster 的指南使用此命令通过 liquibase 为网关项目和微服务生成 Jhipster 初始实体

liquibase:diff

并遇到此错误:

所以我回头引用 jhipster，他们确实提到要更改 pom.xml 中的设置，我也是这样做的:

        <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.zaxxer.hikari.HikariConfig</driver>
            <url>jdbc:sqlserver://localhost:1433;database=IASDB</url>
            <defaultSchemaName>IASDB</defaultSchemaName>
            <username>devuser</username>
            <password>CIATopSecret</password>
            <referenceUrl>hibernate:spring:com.mbb.ias.domain?dialect=org.hibernate.dialect.SQLServer2012Dialect&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>

它会按照上面的消息抛出错误或这个:

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.3:diff (default-cli) on project ias-gateway: Error setting up or running Liquibase: liquibase.exception.DatabaseExceptionnot find database driver: com.zaxxer.hikari.HikariConfig cannot be cast to java.sql.Driver -> [Help 1]

我确实尝试更改我的 pom 以使用 com.microsoft.SQLServerDriver，但它让我失望

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.3:diff (default-cli) on project ias-gateway: Error setting up or running Liquibase: liquibase.exception.DatabaseExceptionnot find database driver: com.microsoft.SQLServerDriver -> [Help 1]

有人建议如何更改我的 pom 吗？如果我想使用子生成器，我需要一一生成实体吗？抱歉这个菜鸟问题。这是我的 Jhipster 信息:

要获得完整的 MSSQL 支持，您应该使用 v3.12.1 - 在我们支持该数据库之前，您的项目是使用 v3.12.0 生成的。您也不应该最初运行 liquibase:diff (在应用首次运行 liquibase 之前它会失败)。

以下代码是来自新生成的项目的 MSSQL liquibase 的 pom 配置，我看到的主要区别是驱动程序标记:

            <configuration>
                <changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
                <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
                <driver></driver>
                <url>jdbc:sqlserver://localhost:1433;database=databaseName</url>
                <defaultSchemaName></defaultSchemaName>
                <username>SA</username>
                <password>yourStrong(!)Password</password>
                <referenceUrl>hibernate:spring:com.mycompany.myapp.domain?dialect=org.hibernate.dialect.SQLServerDialect&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>
