Spring-boot整合liqiubase

1.配置所需的依賴包

<parent>
        <groupId> org.springframework.boot </groupId >
        <artifactId> spring-boot-starter-parent </artifactId>
        <version>1.4.1.RELEASE</version>
    </parent >
    <dependencies>
        <!--liquibase依賴-->
        <dependency>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-core</artifactId>
            <version>3.5.3</version>
        </dependency>
        <dependency>
            <groupId> org.springframework.boot</groupId >
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
            <scope>runtime</scope>
        </dependency>
    </dependencies>

注意，spring-boot-starter-data-jpa這個包也要引入，否則在配置liqiubase的配置類的時候，無法注入Datasource；

2.配置application.yml文件

這裏使用了單獨的數據源，並沒有在liqiubase直接配置數據庫

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/liqiubase?useUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=Asia/Shanghai&allowMultiQueries=true
    username: root
    password: <your password>
    driver-class-name: com.mysql.jdbc.Driver
liquibase:
  change-log: classpath:liquibase/master.xml
  enabled: true
  drop-first: false

3.添加liqiubase的配置類

import liquibase.integration.spring.SpringLiquibase;
import org.springframework.boot.autoconfigure.liquibase.LiquibaseProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
@EnableConfigurationProperties(LiquibaseProperties.class)
public class LiquibaseConfig {


    @Bean
    public SpringLiquibase liquibase(DataSource dataSource,LiquibaseProperties liquibaseProperties) {
        SpringLiquibase springLiquibase = new SpringLiquibase();
        springLiquibase.setDataSource(dataSource);
        springLiquibase.setChangeLog(liquibaseProperties.getChangeLog());
        springLiquibase.setShouldRun(liquibaseProperties.isEnabled());
        springLiquibase.setDropFirst(liquibaseProperties.isDropFirst());
        return springLiquibase;
    }
}

注意，這裏使用的直接啓用了LiquibaseProperties的配置類，該類聲明瞭部分配置的默認值，需要覆蓋的話就在application裏面配置覆蓋即可，注意，該類是直接以liqiubase開頭的配置，並非在spring的第二級，這裏需注意下：

4.啓動類

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }

}
