Question

我正在尝试使用现有数据库（在MySQL上）中的liquibase（3.5.5）。

我已经使用了generateChangeLog命令来生成db.changelog.xml文件。

C：/liquibase-3.5.5/liquibase.bat --driver = com.mysql.jdbc.Driver ^ --classpath = C：/Libraries/mysql-connector-java-5.1.37-bin.jar ^ --changeLogFile = db.changelog.xml ^ --url =“ jdbc：mysql：// vbalder / izalerting” ^ --username = * ^ --password = * ^ generateChangeLog

结果：Liquibase 'generateChangeLog' Successful

生成的db.changelog.xml文件包含具有作者BGADEYNE (generated)和ID（由1533645947580-开头）的changeSet。例如1533645947580-1

向数据库ChangeLog标记中添加了logicalFilePath="db.changelog.xml"
我使用了changelogSync命令来创建和填充DATABASECHANGELOG和DATABASECHANGELOGLOCK表。它们确实包含每个changeSet的行。

C：/liquibase-3.5.5/liquibase --driver = com.mysql.jdbc.Driver ^ --classpath = C：/Libraries/mysql-connector-java-5.1.37-bin.jar ^ --changeLogFile = db.changelog.xml ^ --url =“ jdbc：mysql：// vbalder / izalerting” ^ --username = izalerting ^ --password = alfa ^ changelogSync

结果：Liquibase 'changelogSync' Successful

创建了一个CDI组件，以在应用程序启动时执行db.changelog.xml。

添加了maven依赖项：

<dependency>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-cdi</artifactId>
    <version>3.5.5</version>
</dependency>

添加了CLI组件：

@Dependent
public class LiquibaseProducer {
    @Resource(name="java:/izalerting")
    private DataSource dbConnection;

    @Produces @LiquibaseType
    public CDILiquibaseConfig createConfig() {
        CDILiquibaseConfig config = new CDILiquibaseConfig();
        config.setChangeLog("be/uzgent/iz/alerting/liquibase/db.changelog.xml");
        config.setContexts("non-legacy");
        return config;
    }

    @Produces @LiquibaseType
    public DataSource createDataSource() throws SQLException {
        return dbConnection;
    }

    @Produces @LiquibaseType
    public ResourceAccessor create() {
        return new ClassLoaderResourceAccessor(getClass().getClassLoader());
    }
}

将应用程序部署到WildFly时，我可以看到

DATABASECHANGELOG表包含每个changeSet的一行。

有人知道我在这里做错什么吗？

Answer 1

代替

@Resource(name="java:/izalerting")

我需要使用

@Resource(lookup="java:/izalerting")

在野蝇9上

liquibase会忽略已经执行的changeSets
