Playframework 2.2.x + Java +JPA - 单元测试和生产环境分离数据库

unit-testingplayframeworkplayframework-2.0jpa-2.0

我正在使用Java + Playframework + JPA开发应用程序，使用的是PlayFramework 2.3-M1版本。

我想在运行应用程序时使用MySQL数据库，但是当我使用测试时：

activator test

我想使用内存数据库H2。

怎么做呢？

以下是我的

conf/META-INF/persistence.xml

<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.*"

这是完成任务的最佳方法吗？

谢谢

所以我使用了一些混合/匹配方法来加快测试速度。

我为测试和生产使用了不同的配置文件
我在Prod和Testing中使用了两个不同的JPA持久性单元
在build.sbt中添加覆盖测试执行的配置文件
利用来生成测试模式
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

将以下选项添加到build.sbt文件中

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，我使用以下方式进行测试：

activator test

感谢play-framework谷歌组的用户提供了实现这一点的线索。
