wildfly standalone.xml 配置文件：

xa-datasource：

<xa-datasource jndi-name="java:jboss/datasources/sqlserver" pool-name="sqlserver" enabled="true" use-java-context="true">
<xa-datasource-property name="URL">jdbc:sqlserver://211.100.75.235:1433;databaseName=IPTV;</xa-datasource-property>
<driver>sqlserver</driver>
<xa-pool>
<min-pool-size>1</min-pool-size>
<initial-pool-size>5</initial-pool-size>
<max-pool-size>100</max-pool-size>
<prefill>true</prefill>
</xa-pool>
<security>
<user-name>xxx</user-name>
<password>xxx</password>
</security>
</xa-datasource>

执行后遇到报错：

 javax.persistence.PersistenceException: org.hibernate.MappingException: No Dialect mapping for JDBC type: -9

原因：Hibernate框架的方言（Dialect ）没有数据库中数据类型nvarchar的映射，只有varchar类型的映射。所以在启动时出现此异常。

解决方法：

select  cast(area as varchar(200)) as area from xxx;

把不符合列的类型强制转换。
