JBoss/Wildfly 配置SQLserver服务器
http://blog.csdn.net/haitaolang/article/details/60467118
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>
<datasource jndi-name="java:jboss/datasources/sqlserver" pool-name="sqlserver" enabled="true" use-java-context="true">
<connection-url>jdbc:sqlserver://211.100.75.235:1433;databaseName=IPTV;</connection-url>
<driver>sqlserver</driver>
<security>
<user-name>xxx</user-name>
<password>xxx</password>
</security>
</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。
java.sql.Types对应的值请参考http://blog.sina.com.cn/s/blog_4f925fc30102ep0v.html java.sql.Types对应的sql server2008中的一些值： public final static int BIT = -7; public final static int TINYINT = -6; public final static int SMALLINT = 5; public final static int INTEGER = 4; public final static int BIGINT = -5; public final static int FLOAT = 6; public final static int REAL = 7; public final static int DOUBLE = 8; public final static int NUMERIC = 2; public final static int DECIMAL = 3; public final static int CHAR = 1; public final static int VARCHAR = 12; public final static int LONGVARCHAR = -1; public final static int DATE = 91; public final static int TIME = 92; public final static int TIMESTAMP = 93; public final static int BINARY = -2; public final static int VARBINARY = -3; public final static int LONGVARBINARY = -4; public final static int NULL = 0; public final static int OTHER = 1111; public final static int JAVA_OBJECT = 2000; public final static int DISTINCT = 2001; public final static int STRUCT = 2002; public final static int ARRAY = 2003; public final static int BLOB = 2004; public final static int CLOB = 2005; public final static int REF = 2006; public final static int DATALINK = 70; public final static int BOOLEAN = 16; public final static int ROWID = -8; public static final int NCHAR = -15; public static final int NVARCHAR = -9; public static final int LONGNVARCHAR = -16; public static final int NCLOB = 2011; public static final int SQLXML = 2009;
