今天在做ssh项目开发的时候遇到一个问题,保存数据的时候报错: Write operations are not allowed in read-only mode (FlushMode.NEVER/ 后参考这篇文章才知道出了什么问题:http://www.aichengxu.com/view/37412 原来在Spring事务管理中save类的方法都没有read-only=true,但是我的方法是add*,所以就出现开头讲的问题,把add*方法改成save*就可以了. <!-- 配置事务策略…

使用Spring提供的Open Session In View而引起Write operations are not allowed in read-only mode (FlushMode.NEVER) 错误解决: 在没有使用Spring提供的Open Session In View情况下,因需要在service(or Dao)层里把session关闭,所以lazy loading 为true的话,要在应用层内把关系集合都初始化,如 company.getEmployees(),否则Hiber…

(转+作者个人理解) 最近在配置 Structs, Spring 和Hibernate整合的问题: 开启OpenSessionInViewFilter来阻止延迟加载的错误的时候抛出了这个异常: org.springframework.dao.InvalidDataAccessApiUsageException错误 但是在我们开启OpenSessionInViewFilter这个过滤器的时候FlushMode就已经被默认设置为了MANUAL! 如果FlushMode是MANUAL或NEVEL,在操…

最近学习ssh框架,总是出现这问题,后查证是没有开启事务. 如果采用注解方式,直接在业务层加@Transactional 并引入import org.springframework.transaction.annotation.Transactional; 详细信息,可以参考下面博客: 参考资料:http://blog.csdn.net/longxia1987/article/details/7819242 org.springframework.dao.InvalidDataAccessApi…

© 版权声明:本文为博主原创文章,转载请注明出处 1.问题描述 搭建SSH框架后,为测试事务配置是否生效,因此在事务配置中取消了保存方法,然后再保存方法中手动抛出异常(已测试配置事务后没有保存成功),查看是否保存成功,如果保存成功则说明事务配置生效.但是测试保存时报错如下: org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (…

这个异常我在网上查看了很多资料,一般都说是hibernate的session问题,让重新两个方法,但是我以前用的时候没问题啊,所以一直找问题,终于这个bug让我找到了,就是因为我插入操作的时候用的是别的实体类的service层,而且插入的实体类也没有写业务层Service和Dao层,然后就用实体类service的父层,就是BaseService(方法都在里面封装的),利用它条用save方法进行保存,写了service层和dao层,结果就好了...…
