is not mapped问题,SPRing加载jar中配置文件错误如下:
org.hibernate.hql.ast.QuerySyntaxException: Content is not mapped [select new Content (t.id,t.name,t.values,t.systemType,t.type,t.sortnumber) from Content t where 1=1 and t.type = ? and t.systemType = ? order by t.sortnumber desc ]at org.hibernate.hql.ast.util.sessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:158)at org.hibernate.hql.ast.tree.FromElementFactory.addFromElement(FromElementFactory.java:87)at org.hibernate.hql.ast.tree.FromClause.addFromElement(FromClause.java:70)at org.hibernate.hql.ast.HqlSqlWalker.createFromElement(HqlSqlWalker.java:255)at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromElement(HqlSqlBaseWalker.java:3056)at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromElementList(HqlSqlBaseWalker.java:2945)at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromClause(HqlSqlBaseWalker.java:688)
场景描述:
Content 在A项目打包的jar文件中,单独在A项目中使用没有任何问题.
B项目的Spring配置如下:
<property name="mappingDirectoryLocations"><list><value>classpath:/com/mythink/entity/</value></list></property>
上网查找原因,在使用spring加载jar包中的配置文件时，不支持通配符，需要一个一个引入.
为验证,将配置改成如下:
<property name="mappingResources"> <list> <value>com/mythink/entity/common/Content.hbm.xml</value> </list></property>
重启访问,,果然没问题..但是这样要一个一个加载配置文件,,超级麻烦..继续搜索!!
嘿嘿,,还真找到了好方法,更改配置如下:
<!-- 加载jar包中的配置文件,解决is not mapped 问题 --><property name="mappingJarLocations"> <list> <value>/WEB-INF/lib/xxx.jar</value> </list> </property> <property name="mappingDirectoryLocations"><list><value>classpath:/com/mythink/entity/</value></list></property>
重启,,可以正常加载Hibernate配置文件了..
