我似乎找不到关于如何使用Play Framework2.5+的Hibernate搜索的好教程。

谢谢你！

你的配置好像少了一些东西。这里是我使用的工作配置的一个例子（只是替换了真实的名称）。请注意，没有使用hibernate.cfg.xml。

build.sbt：

val hibernateVersion = "4.3.10.Final"
val mySqlConnectorVersion = "5.1.36"

libraryDependencies ++= Seq(
  javaJpa
)
...
libraryDependencies ++= Seq(
    ...
    "org.hibernate" % "hibernate-entitymanager" % hibernateVersion,
    "mysql" % "mysql-connector-java" % mySqlConnectorVersion
    ...

application.conf：

# ~~~~~
# MySql 5.6
db.default.driver=com.mysql.jdbc.Driver
db.default.username="user" - put here your DB user name
db.default.password="password" - put here your DB user password
dbhosts="hostip:port" - put here your host and DB port
dbschema="dbschema" - put here the exact case-sensitive name of the DB schema
dbproperties="?autoReconnect=true"
db.default.url="mysql://"${db.default.username}":"${db.default.password}"@"${dbhosts}"/"${dbschema}${dbproperties}
db.default.jndiName=MyDS
jpa.default=myDbPersistanceUnit

<persistence-unit name="myDbPersistanceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<non-jta-data-source>MyDS</non-jta-data-source>
    <!--Model mapping (optional) like below-->
    <!--class>persistence.models.SomeEntityClass</class>-->
    ....
<properties>
    <!--Hibernate properties -->
    <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
    <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
</properties>
