Question

我正在使用JHipster，当我运行https://other-domain.com/path/to/service-worker.js时，我收到以下错误

sudo mvn liquibase:diff

我不知道为什么[INFO] Settings ---------------------------- [INFO] driver: org.postgresql.Driver [INFO] url: jdbc:postgresql://localhost/gastos8 [INFO] username: gastos8 [INFO] password: ***** [INFO] use empty password: false [INFO] properties file: null [INFO] properties file will override? false [INFO] prompt on non-local database? true [INFO] clear checksums? false [INFO] changeLogFile: src/main/resources/config/liquibase/master.xml [INFO] context(s): null [INFO] label(s): null [INFO] referenceDriver: null [INFO] referenceUrl: hibernate:spring:com.cboujon.domain?dialect=org.hibernate.dialect.PostgreSQL82Dialect [INFO] referenceUsername: null [INFO] referencePassword: null [INFO] referenceDefaultSchema: null [INFO] diffChangeLogFile: src/main/resources/config/liquibase/changelog/20150807132702_changelog.xml [INFO] ------------------------------------------------------------------------ [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 9.554s [INFO] Finished at: Fri Aug 07 13:27:12 ART 2015 [INFO] Final Memory: 18M/179M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.3.2:diff (default-cli) on project gastos8: Error setting up or running Liquibase: liquibase.exception.DatabaseException: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "gastos8" -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

这是我的配置文件：

应用dev.yml

[INFO]     username: gastos8

我做错了什么？

Answer 1

Liquibase maven插件无法读取application.yml以了解如何连接到您的数据库，它在您的pom.xml中有自己的配置。所以你必须把它放在那里。

你为什么要用sudo执行maven？现在，您可能拥有root拥有的项目文件，这通常是一个坏主意。

Answer 2

正如在接受的答案中所说，maven没有阅读application.yml。

但是，如果您对maven liquibase插件定义中的数据库配置感到不舒服，则可以使用maven属性和liquibase配置文件。

1 - 在liquibase-maven-plugin配置中，添加propertyFile：

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>${liquibase.version}</version>
    <configuration>
        <propertyFileWillOverride>true</propertyFileWillOverride>
        <propertyFile>src/main/resources/liquibase.properties</propertyFile>
    </configuration>
    (...)
</plugin>

2 - 在src / main / resources下的任何位置创建liquibase属性文件。例如，src / main / resources / config / liquibase：

contexts:${liquibase.contexts}
changeLogFile:src/main/resources/config/liquibase/master.xml
driver:${dataSource.project.driverClass}
url:${dataSource.project.jdbcURL}
username:${dataSource.project.user}
password:${dataSource.project.password}
verbose:true
dropFirst:false

3 - 告诉maven过滤你的liquibase属性文件，以便用maven属性替换值。在<build>中，请求maven过滤您的liquibase配置文件：

<build>
    <resources>
        <resource>
            <directory>src/main/resources/config/liquibase</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    (...)
</build>

4 - 为允许启动liquibase目标的每个配置文件添加maven属性：

<profile>
    <id>dev</id>
    (...)
    <properties>
        <liquibase.contexts></liquibase.contexts>
        <dataSource.project.driverClass>org.mariadb.jdbc.Driver</dataSource.project.driverClass>
        <dataSource.project.jdbcURL>jdbc:mariadb://localhost:3306/yourDatabaseName</dataSource.project.jdbcURL>
        <dataSource.project.user>${datasource.username}</dataSource.project.user>
        <dataSource.project.password>${datasource.password}</dataSource.project.password>
    </properties>
</profile>

5 - 使用maven启动liquibase目标并在命令行中设置凭据：

mvn resources:resources liquibase:update -Pdev -Ddatasource.username=root -Ddatasource.password=root

Answer 3

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

中

datasource:
        driver-class-name: com.mysql.jdbc.jdbc2.optional.MysqlDataSource
        url: jdbc:mysql://localhost:3306/DBNAME?useUnicode=true characterEncoding=utf8
        name: DBNAME
        username: USERNAME 
        password: PWD

你必须改变：

DBNAME
USERNAME 
PWD

不要忘记改变生产

src/main/resources/config/application-prod

url中的

和localhost：jdbc：mysql：// localhost：3306到你的网址

Answer 4

datasource:
        driver-class-name: com.mysql.jdbc.jdbc2.optional.MysqlDataSource
        url: jdbc:mysql://database hosting address:3306/database Name?useUnicode=true characterEncoding=utf8
        name: database Name
        username: database user name 
        password: and put here database user password
