playframework 2.X JPA to MSSQL无法构建Hibernate SessionFactory

Question

我想使用JPA连接到MSSQL，使用示例计算机-database-jpa可以访问h2 sql，但是当我更改为mssql时，它会输出错误消息“PersistenceException：[PersistenceUnit：defaultPersistenceUnit]无法构建Hibernate SessionFactory”谁能帮我谢谢！

我的application.conf

# Database configuration
# ~~~~~ 
# You can declare as many datasources as you want.
# By convention, the default datasource is named `default`
db.default.driver=net.sourceforge.jtds.jdbc.Driver
db.default.url="jdbc:jtds:sqlserver://127.0.0.1:1433;DatabaseName=TCGW;SelectMethod=cursor:sendStringAsUnicode=true"
db.default.user=qqqq
db.default.password=qqqq
#db.default.driver=org.h2.Driver
#db.default.url="jdbc:h2:mem:play"
db.default.jndiName=DefaultDS
applyEvolutions.default=true
hibernate.use_sql_comments=true

我的persistence.xml

<persistence-unit name="defaultPersistenceUnit" >
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <non-jta-data-source>DefaultDS</non-jta-data-source>
