求大神帮忙解决！！！

[whos2002110]

@Query 里面的sql怎么写的？ 把from的表名改为CAApplay

[业余草]

贴上你的代码看看

[S117]

caapplay is not mapped

[a353041396]

package com.sgl.repository; import com.sgl.model.CAApplay; //import org.springframework.data.jpa.repository.Query; import org.springframework.data.repository.CrudRepository; import org.springframework.data.repository.PagingAndSortingRepository; import org.springframework.stereotype.Repository; /** * @author: john * @version: 1.0 2014-05-29 13:38 */ @Repository public interface CAApplayRepository extends CrudRepository<CAApplay, String>, PagingAndSortingRepository<CAApplay, String> { //@Query("select org_code from caapplay where org_code=?") CAApplay findByOrgCode(String orgCode); //@Query("select ca_company from caapplay where ca_company=?") CAApplay findByCaCompany(String caCompany); } 这个是代码，请参考

[whos2002110]

CAApplay 没有被映射为表caapplay， hibernate配置出问题了吧

[a353041396]

找不到hibernate配置在那，把表名改了结果还是一样

[a353041396]

引用 5 楼 whos2002110 的回复:

CAApplay 没有被映射为表caapplay， hibernate配置出问题了吧

检查了下 我没用配置文件 我用的全是注解不过 确实是注解没有映射相应的数据表，谢谢拉

[luanpenggg]

楼主解决了吗，我用的全注解 但是还是说找不到实体映射
