java - 首次运行 jhipster 应用程序失败，启动 tomcat 上下文时出错

标签 java maven jhipster

我正在使用 JHipster 构建一个 Java 应用程序。

我单独创建了一个 mysql 数据库，我想我已经通过将其连接信息粘贴到 pom.xml 文件的 liquibase 插件部分(注意:这是一个虚构的 IP)将其连接到应用程序):

<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://108.10.10.10:3306/calc</url>

                <version>${project.parent.version}</version>
            </dependency>
        </dependencies>
    </plugin>

当我运行应用程序时:

mvn spring-boot:run

...它很好地完成了 npm 和 bower 任务，但是当需要执行 java 方面的事情时，它会失败并出现一个大错误:

最佳答案

liquibase 连接信息仅用于数据库重构。

实际应用程序的数据库(开发)连接信息应设置为:

src/main/resources/config/application-dev.yml

更新后，它启动时没有错误。

连接信息文档:http://jhipster.github.io/creating_an_app.html

注意:

  1. 您必须创建一个以 appname 命名的新架构。
  2. 首次运行时，确保该架构中没有表
  3. 在 pom.xml 中填写 liquibase 配置，并在 application-dev.yml 文件中设置该配置。
  4. 使用 mvn spring-boot:run 运行您的应用
