I have a IDEA project using maven2.
I want to use hibernate + mysql, what dependancies do 开发者_运维百科I need?
first of all, I separate the versions from the artifacts:
<properties>
<spring.version>3.0.3.RELEASE</spring.version>
<hibernate.version>3.5.3-Final</hibernate.version>
<mysql.version>5.1.13</mysql.version>
<junit.version>4.7</junit.version>
</properties>
then I reference them like this:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql.version}</version>
<!-- perhaps using scope = provided, as this will often
be present on the app server -->
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<!-- or hibernate-entitymanager if you use jpa -->
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
That way you keep the versions all in one place and can easily update them, especially if you reference e.g. multiple spring artifacts.
BTW: these should be the current versions, but you can always look up current versions using MvnRepository.com
Pasting these dependencies into pom.xml
after <depdendencies>
should work:
<!-- MySQL database driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.9</version>
</dependency>
<!-- Hibernate framework -->
<dependency>
<groupId>hibernate</groupId>
<artifactId>hibernate3</artifactId>
<version>3.2.3.GA</version>
</dependency>
<!-- Hibernate library dependecy start -->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>3.2.1</version>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency>
<!-- Hibernate library dependecy end -->

You may want to tweak the version numbers on the dependencies.
IntelliJ IDEA 9 can find Maven dependencies based on class name. If you start using a class which isn't available in the current dependencies you can get IntelliJ to help find it by using Alt-Enter.
I used this to great effect with a Java-base Subversion hook implementation I am building at work. I was able to get SVNKit and Google Guice dependencies into my project fairly easily this way.
MySQL in your case may be trickier since it is more of a runtime dependency when using Hibernate.
