弹簧启动时的多个liquibase配置

Question

我有使用2个数据库的spring启动应用程序。我定义了2个提供指定数据源的配置。我想要有由liquibase单独管理的数据源。我定义了2个独立的更新日志文件。

问题是我无法为liquibase定义2个独立的bean。

这里是我的配置类：

... 
public class CCSConfiguration { 
    ... 

    @Bean 
    @ConfigurationProperties("ccs.liquibase") 
    public LiquibaseProperties ccsLiquibaseProperties() { 
     return new LiquibaseProperties(); 
    } 

    @Bean 
    public SpringLiquibase ccsLiquibase(LiquibaseProperties liquibaseProperties) { 
     ... 
    } 
    ... 
} 



... 
public class CCAConfiguration { 
    ... 
    @ConfigurationProperties("cca.liquibase") 
    public LiquibaseProperties ccaLiquibaseProperties() { 
     return new LiquibaseProperties(); 
    } 

    @Bean 
    public SpringLiquibase ccaLiquibase(LiquibaseProperties liquibaseProperties) { 
     ... 
    } 
    ... 
} 

和属性：

cca: 
    liquibase: 
     change-log: classpath:config/liquibase/cca/master.xml 
ccs: 
    liquibase: 
     change-log: classpath:config/liquibase/ccs/master.xml 

有了这个配置，同时运行机应用我得到以下错误：

2017-04-11 14:26:55.664 WARN 34292 --- [ restartedMain] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'liquibase' available

Description: 

A component required a bean named 'liquibase' that could not be found. 


Action: 

Consider defining a bean named 'liquibase' in your configuration. 

那么，有没有可能为不同的数据源定义多个liquibase bean？

Answer 1

有两种选择：

1. 你定义一个bean命名liquibase让春天启动整合过程中你第一次DS更新架构。你必须处理手动第二个

2. 禁用liquibase自动更新在启动时

启用：假

，并确定自己的方式DS和liquibase豆更新你的两个数据库
