添加依赖

<dependency>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-core</artifactId>
</dependency>

添加配置

yml 复制代码

spring:
  liquibase:
    contexts: dev,test
    enabled: true

编写liquibase配置类

java 复制代码

@Configuration
@EnableConfigurationProperties(LiquibaseProperties.class)
public class LiquibaseConfig {
    @Bean
    public SpringLiquibase liquibase(DataSource dataSource, LiquibaseProperties properties) {
        SpringLiquibase liquibase = new SpringLiquibase();
        liquibase.setDataSource(dataSource);
        //指定changelog的位置，这里使用的一个master文件引用其他文件的方式
        liquibase.setChangeLog("classpath:liquibase/master.xml");
        liquibase.setContexts(properties.getContexts());
        liquibase.setDefaultSchema(properties.getDefaultSchema());
        liquibase.setDropFirst(properties.isDropFirst());
        liquibase.setShouldRun(properties.isEnabled());
        liquibase.setChangeLogParameters(properties.getParameters());
        liquibase.setRollbackFile(properties.getRollbackFile());
        liquibase.setShouldRun(true);
        return liquibase;
    }
}

编写master.xml文件(注意includeAll配置的路径与changelog文件的路径)

xml 复制代码

<?xml version="1.0" encoding="utf-8"?>
<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd">
    <property name="now" value="now()" dbms="h2"/>
    <property name="now" value="now()" dbms="mysql"/>
    <property name="floatType" value="float4" dbms="postgresql, h2"/>
    <property name="floatType" value="float" dbms="mysql, oracle, mssql, mariadb"/>
    <property name="clobType" value="clob" dbms="h2"/>
    <property name="clobType" value="clob" dbms="mysql, oracle, mssql, mariadb, postgresql"/>
    <property name="uuidType" value="varchar(36)" dbms="h2, mysql, mariadb"/>
    <includeAll path="liquibase/changelog/"/>
</databaseChangeLog>

编写changelog文件 00000000000000_init_schema.xml

xml 复制代码

<?xml version="1.0" encoding="utf-8"?>
<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd
                        http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">
    <property name="autoIncrement" value="true"/>
    <changeSet author="system" id="00000000000001" context="dev">
        <createTable tableName="hello_date_time_wrapper">
            <column  name="id" type="BIGINT">
                <constraints primaryKey="true" primaryKeyName="hello_date_time_wrapperPK"/>
            </column>
            <column name="instant" type="timestamp"/>
            <column name="local_date_time" type="timestamp"/>
            <column name="offset_date_time" type="timestamp"/>
            <column name="zoned_date_time" type="timestamp"/>
            <column name="local_time" type="time"/>
            <column name="offset_time" type="time"/>
            <column name="local_date" type="date"/>
        </createTable>
    </changeSet>
</databaseChangeLog>
