unit-testing - Playframework 2.2.x + Java +JPA - 用于单元测试和生产的单独数据库

Question

我正在使用 Java + Playframework + JPA 使用 PlayFramework 2.3-M1 来开发应用程序。

我想在运行应用程序时使用 MySQL 数据库，但是当我运行测试时使用

activator test

我想在内存数据库 H2 中使用。

如何才能做到这一点 ？

下面是我的

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>

配置文件/应用程序.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/匹配方法来进行更快的测试

我使用单独的配置文件进行测试和生产

我为生产和测试使用了两种不同的 JPA 持久性单元

在 build.sbt

中添加了覆盖测试执行的配置文件

用于生成测试模式

利用进化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

配置文件/应用程序.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

然后将以下选项添加到 build.sbt 文件

生成.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>

最后我测试它使用

activator test

感谢 play-framework google group 的用户为实现这一目标提供了线索。
