Spring2.0事务配置问题（重写父类方法后出错）
由于一些功能模块用到的Service和DAO层的方法类似，现将类似的方法进行重构，提出基本的Service和DAO，真正用到的Service和DAO只要实现或者继承即可。在重构后遇到事务配置问题，具体如下。
?
抛出异常：
org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.
?at org.springframework.orm.hibernate3.HibernateTemplate.checkWriteOperationAllowed(HibernateTemplate.java:1085)
?at org.springframework.orm.hibernate3.HibernateTemplate$12.doInHibernate(HibernateTemplate.java:624)
?at org.springframework.orm.hibernate3.HibernateTemplate.execute(HibernateTemplate.java:362)
?at org.springframework.orm.hibernate3.HibernateTemplate.save(HibernateTemplate.java:622)
?

Spring2.0配置：
<aop:config><aop:advisorpointcut="execution(* aumy2008.service.impl..*.*(..)) "advice-ref="txAdviceRet" /></aop:config><tx:advice id="txAdviceRet"transaction-manager="transactionManager"><tx:attributes><tx:method name="get*" read-only="true"propagation="REQUIRED" /><tx:method name="load*" read-only="true"propagation="REQUIRED" /><tx:method name="find*" read-only="true"propagation="REQUIRED" /><tx:method name="*" propagation="REQUIRED" /></tx:attributes></tx:advice>
?
重构后的基本接口和实现类的部分代码：?
public interface IBaseService<T> {public Long add(T t);public void modify(T t);public void addOrModify(T t);......}?
public class BaseService<T> implements IBaseService<T> {private IRBaseDao<T> irBaseDao;private boolean isSwitchCharsetTranslate;public BaseService(IRBaseDao<T> irBaseDao, boolean isSwitchCharsetTranslate)throws Exception {if (irBaseDao == null) {throw new Exception("irBaseDao may not be null");}this.irBaseDao = irBaseDao;this.isSwitchCharsetTranslate = isSwitchCharsetTranslate;}public Long add(T t) {return (Long) this.irBaseDao.save(t);}public void addOrModify(T t) {this.irBaseDao.saveOrUpdate(t);}public void modify(T t) {this.irBaseDao.update(t);}......}?
public interface IRBaseDao<T> {public Serializable save(Object o);public void update(Object o);public void saveOrUpdate(Object o);......}?public class RBaseDao<T> extends HibernateDaoSupport implements IRBaseDao<T> {public Serializable save(Object o) {Serializable id = getHibernateTemplate().save(o);this.flush();return id;}public void update(Object o) {getHibernateTemplate().update(o);this.flush();}public void saveOrUpdate(Object o) {getHibernateTemplate().saveOrUpdate(o);this.flush();}......}?具体业务的接口和实现类的部分代码：
public interface ITypeService extends IBaseService<Type> {}?
public class TypeService extends BaseService<Type> implements ITypeService {private IRBaseDao<Type> typeDAO;public boolean isSwitchCharsetTranslate;public TypeService(IRBaseDao<Type> typeDAO, boolean isSwitchCharsetTranslate)throws Exception {super(typeDAO, isSwitchCharsetTranslate);this.typeDAO = typeDAO;this.isSwitchCharsetTranslate = isSwitchCharsetTranslate;}public void addOrModify(Type t) {typeDAO.saveOrUpdate(toDBValue(t));}public Long add(Type t) {return (Long) typeDAO.save(toDBValue(t));}public void modify(Type t) {typeDAO.update(toDBValue(t));}private Type toDBValue(Type type) {......return type;}}?public interface ITypeDAO extends IBaseDao<Type> {}?public class TypeDAO extends RBaseDao<Type> implements ITypeDAO {}
如果TypeService不重写父类的方法，运行正常
代码如：
public class TypeService extends BaseService<Type> implements ITypeService {public TypeService(IRBaseDao<Type> typeDAO, boolean isSwitchCharsetTranslate)throws Exception {super(typeDAO, isSwitchCharsetTranslate);}}?
我现在就是想在TypeService类中实现字符集的转换，需要重写add等三个方法，当重写后，运行就报开始给出的异常。 5. </aop:config>org.springframework.transaction.interceptor.TransactionProxyFactoryBean2 楼 aumy2008 2008-01-09 谢谢 xly_971223 ！
