1、这是版本问题，参见此问题的Answer
https://www.e-learn.cn/content/wangluowenzhang/287437
版本符合后，又出现error
org.springframework.orm.hibernate4.HibernateSystemException: getFlushMode is not valid without active transaction; nested exception is org.hibernate.HibernateException: getFlushMode is not valid without active transaction org.springframework.orm.hibernate4.SessionFactoryUtils.convertHibernateAccessException(SessionFactoryUtils.java:218) org.springframework.orm.hibernate4.HibernateTemplate.doExecute(HibernateTemplate.java:344) org.springframework.orm.hibernate4.HibernateTemplate.executeWithNativeSession(HibernateTemplate.java:309) org.springframework.orm.hibernate4.HibernateTemplate.save(HibernateTemplate.java:618) com.test3.dao.impl.UserDaoImpl.save(UserDaoImpl.java:13) com.test3.service.impl.UserServiceImpl.save(UserServiceImpl.java:17) com.test3.action.UserAction.add(UserAction.java:25) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) java.lang.reflect.Method.invoke(Method.java:498) ognl.OgnlRuntime.invokeMethod(OgnlRuntime.java:870)
2、参考该链接第二种方法
https://blog.csdn.net/maoyuanming0806/article/details/61417995
若此时无error最好不过了，现实很残酷
又一error
org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.
3、检查spring的配置文件，查看事务启动
使用注解的情况
<tx:annotation-driven transaction-manager="transactionManager"/>
参考https://blog.csdn.net/yu0_zhang0/article/details/77938009
没有使用注解
检查配置切入点路径是否正确
个人是因为路径写错，修改后无错误。
记录一次error三连。
