在Spring Boot中为liquibase配置dataSource
我有一个spring boot应用程序,我想为其添加liquibase配置更改日志。
我创建了一个LiquibaseConfig类来配置liquibase:
@Configurationpublic class LiquibaseConfiguration {
@Value("${com.foo.bar.liquibase.changelog}")
private String changelog;
@Autowired
MysqlDataSource dataSource;
@Bean
public SpringLiquibase liquibase() {
SpringLiquibase liquibase = new SpringLiquibase();
liquibase.setDataSource(dataSource);
liquibase.setChangeLog(changelog);
return liquibase;
}
}
并且我已经在属性文件中配置了数据源信息:
spring.datasource.url=jdbc:mysql://localhost:3306/dmsspring.datasource.username=root
spring.datasource.password=test
spring.datasource.testWhileIdle = true
spring.jpa.show-sql = true
#liquibase
com.foo.bar.liquibase.changelog=classpath:/db/changelog/db.changelog.xml
当我运行我的应用程序时,我收到此错误:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'liquibaseConfiguration': Unsatisfied dependency expressed through field 'dataSource': No qualifying bean of type [com.mysql.jdbc.jdbc2.optional.MysqlDataSource] found for dependency [com.mysql.jdbc.jdbc2.optional.MysqlDataSource]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mysql.jdbc.jdbc2.optional.MysqlDataSource] found for dependency [com.mysql.jdbc.jdbc2.optional.MysqlDataSource]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
现在我知道这意味着应用程序无法自动连接,MysqlDataSource dataSource;
但是我需要将数据源传递给liquibase
bean。我怎样才能做到这一点?
回答:
这是将liquibase集成到Spring Boot中的简单步骤
回答:
添加liquibase依赖
摇篮
runtime "org.liquibase:liquibase-core"
马文
<dependency> <groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<scope>runtime</scope>
</dependency>
回答:
在以下位置添加liquibase changelog文件路径 application.yml
liquibase: enabled: true #this is optional as enabled by default
change-log: classpath:/liquibase/db-changelog.xml
通知物业 我指的路径
,所以你应该有一个文件名 中
步骤3
将更改集添加到文件上,并在启动Spring-Boot应用程序(spring-boot:run
)时加载您的更改集。
这将使用dataSource
您的应用程序使用的默认值。

更新资料
对于@veben在注释使用中指出的Spring Boot 2.0
spring: liquibase:
change-log: #path
