postgresql - How can I use liquibase in Spring Project -

i trying learn liquibase. couldn't apply steps in samples. can tell me step step how can add table or column database , see changes ?

my project spring mvc project , use maven, hibernate, postgresql , change database programmatically.

you need liquibase , hibernate jars. consider have pojo class person id,name,gender properties. create getters , setters of these properties.

you need create liquibase file (db-changelog.xml)

for example :

<?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-2.0.xsd">      <changeset author="rover" id="123456789-1">         <createtable tablename="person">             <column autoincrement="true" name="person_id" type="bigint">                 <constraints nullable="false" primarykey="true" />             </column>             <column name="name" type="varchar(255)" />             <column name="gender" type="varchar(2)" />                    </createtable>     </changeset> </databasechangelog> 

don't forget add liquibase bean in bean

<bean id="liquibaseupdater" class="liquibase.integration.spring.springliquibase">     <property name="datasource" ref="datasource" />     <property name="changelog" value="classpath:db-changelog.xml" /> </bean> 

you need add spring/hibernate beans.
