Playframework 2.2.x + Java + JPA - 用于单元测试和生产的独立数据库

Question

我使用Java + Playframework + JPA使用PlayFramework 2.3-M1开发应用程序.

我想在运行应用程序时使用MySQL数据库,但是当我运行test时使用

activator test

我想在内存数据库H2中使用.

如何才能做到这一点 ？

以下是我的

CONF/META-INF/persistence.xml中

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
             http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">

    <persistence-unit name="prod" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>prodDS</non-jta-data-source>
        <properties>
            <property name="hibernate.dialect" 
                      value="org.hibernate.dialect.MySQL5Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
            <property name="hibernate.show_sql" value="true"></property>
            <property name="hibernate.format_sql" value="true"></property>
        </properties>
    </persistence-unit>

    <persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>TestDS</non-jta-data-source>
        <properties>
            <property name="hibernate.dialect" 
                      value="org.hibernate.dialect.H2Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
            <property name="hibernate.show_sql" value="true"></property>
            <property name="hibernate.format_sql" value="true"></property>
        </properties>
    </persistence-unit>

</persistence>

CONF/application.conf

# Database configuration
# ~~~~~ 
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
#
db.test.driver=org.h2.Driver
db.test.url="jdbc:h2:mem:play"
db.test.user=sa
db.test.password=""

db.test.jndiName=TestDS

jpa.test=testPersistenceUnit

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://X.X.X.X/lb"
db.default.user=lb
db.default.password="lb"

#
# You can expose this datasource via JNDI if needed (Useful for JPA)
db.default.jndiName=DefaultDS


jpa.default=defaultPersistenceUnit


# Evolutions
# ~~~~~
# You can disable evolutions if needed
evolutionplugin=disabled

# Ebean configuration
# ~~~~~
# You can declare as many Ebean servers as you want.
# By convention, the default server is named `default`
#
ebean.default="models.*"

这是完成它的最佳方法吗？

谢谢

Answer 1

所以我使用了一些混合/匹配方法来加快测试速度

1. 我使用单独的配置文件进行测试和生产
2. 我使用两种不同的JPA持久单元进行产品和测试
3. 添加了overrode配置文件,以便在build.sbt中执行测试
4. 利用 生成测试模式
5. 利用evolution将测试数据夹具加载到测试数据中

以下是我的文件:

CONF/test.conf

db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:lb"
db.default.user=lb
db.default.password=""

#
# You can expose this datasource via JNDI if needed (Useful for JPA)
db.default.jndiName=DefaultDS


jpa.default=testPersistenceUnit


# Evolutions
# ~~~~~
# You can disable evolutions if needed
#evolutionplugin=disabled

CONF/application.conf

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://X.X.X.X/lb"
db.default.user=lb
db.default.password="lb"

#
# You can expose this datasource via JNDI if needed (Useful for JPA)
db.default.jndiName=DefaultDS

jpa.default=defaultPersistenceUnit

# Evolutions
# ~~~~~
# You can disable evolutions if needed
evolutionplugin=disabled

然后在build.sbt文件中添加以下选项

build.sbt

javaOptions in Test += "-Dconfig.file=conf/test.conf"

最后是persistence.xml文件

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">

    <!--Persistence Unit for Production-->

    <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>DefaultDS</non-jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
            <property name="hibernate.show_sql" value="true"></property>
            <property name="hibernate.format_sql" value="true"></property>
        </properties>
    </persistence-unit>

    <!--Persistence Unit for Testing-->

    <persistence-unit name="testPersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>DefaultDS</non-jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
            <property name="hibernate.show_sql" value="false"></property>
            <property name="hibernate.format_sql" value="true"></property>
        </properties>
    </persistence-unit>
</persistence>

最后我用它来测试它

activator test

感谢play-framework google group的用户获得了实现这一目标的线索.
