【中文标题】只读模式下不允许写操作 (FlushMode.MANUAL)【英文标题】：Write operations are not allowed in read-only mode (FlushMode.MANUAL) 【发布时间】：2015-12-18 23:13:33 【问题描述】：我是使用 Spring 的新手 我正在使用 JSF+Hibernate+Spring 开发一个简单的 JEE 应用程序 尝试更新 DAO 上的值时遇到一些问题 我确定问题与 Spring 配置 xml 文件有关，但我不知道是什么。
这是我的配置文件：

【问题讨论】：
【参考方案1】：我认为你应该添加一个事务管理器 bean。
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
和
为应该是事务的方法添加@Transactional注解。
希望这会有所帮助。
【讨论】：
我已经按你说的配置了，但是我现在有另一个问题......上面发布了 我要添加的一个限定符是将 readOnly 设置为 false。@Transactional(readOnly = false) 并确保您正在导入正确的注释 org.springframework.transaction.annotation.Transactional，而不是 javax.transaction.Transactional。希望这可以节省一些时间。【参考方案2】：
尝试改变这一点：
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
与：
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
【讨论】：
【参考方案3】：一旦更改了 xml 配置文件和 DAO 我收到以下错误：
Grave: Exception while loading the app
Grave: Undeployment failed for context /JSFHibernateSpring
Grave: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'alumnoBO' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.sun.proxy.$Proxy273 implementing com.javarevolutions.jdbc.dao.IfaceAlumno,org.springframework.beans.factory.InitializingBean,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised' to required type 'com.javarevolutions.jdbc.dao.ImplAlumno' for property 'alumnoDAO'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.sun.proxy.$Proxy273 implementing com.javarevolutions.jdbc.dao.IfaceAlumno,org.springframework.beans.factory.InitializingBean,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [com.javarevolutions.jdbc.dao.ImplAlumno] for property 'alumnoDAO': no matching editors or conversion strategy found

【讨论】：
【参考方案4】：您可以通过以下方式解决问题：
-
在保存时检查 Bean/Model 类提供的所有强制性数据。
检查是否遵循唯一约束的概念，如果没有在唯一列中添加不同的数据。
如果问题仍未解决，则在方法上方添加@Transaction 注解，但要使用@Transaction 方法创建 HibernateTransactionManager 的对象
@Bean
public HibernateTransactionManager transactionManager()
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(getLocalSessionFactoryBean().getObject());
return txManager;
【讨论】：
【参考方案5】：如果你使用Java配置，只需添加@EnableTransactionManagement (org.springframework.transaction.annotation.EnableTransactionManagement)
