代码是这样的：
import static jodd.jtx.JtxPropagationBehavior.PROPAGATION_SUPPORTS;
@PetiteBean
public class FooService {
@PetiteInject
AppDao appDao;
@Transaction(propagation = PROPAGATION_SUPPORTS, readOnly = false)
public void storeUser(User user) {
appDao.store(user);
}
@Transaction(propagation = PROPAGATION_SUPPORTS)
public User findUserById(long id) {
return appDao.findById(User.class, Long.valueOf(id));
}
@Transaction(propagation = PROPAGATION_SUPPORTS)
public void updateDetails(User user) {
appDao.updateUserName(user); //line no 18
appDao.updateAddress(user); //line no 19
}
}
如果第18行成功执行并且第19行执行存在异常，那么由于第18行引起的更改应该是回滚。我怎么能这样做。？
已更改::
@Transaction
public void updateDetails(User user) throws DatabaseException {
try {
appDao.updateUserName(user); //line no 18
appDao.updateAddress(user); //line no 19
} catch (DatabaseException e) {
e.printStackTrace();
System.out.println("Throwing Exception" );
throw new DatabaseException(e.getMessage());
}
}
实际代码::
@Transaction
public void updateCategory(CategoryData categoryData) throws DatabaseException {
try {
Category category = DataConvertionUtil.prepareCategory(categoryData);
userDao.updateCategory(category);
userDao.updateCategory1(category);
} catch (DatabaseException e) {
e.printStackTrace();
System.out.println("Throwing Exception" );
throw new DatabaseException(e.getMessage());
}
}

我正在使用mysql数据库。请帮帮我...
答案 0 :(得分：1)
抛出异常。抛出异常时，JTX代理将捕获它并标记事务以进行回滚。
此行为在AnnotationTxAdvice类中定义，虽然这不是您应该非常关心的事情：）
快速概述告诉我发生异常是因为您有主键的重复条目：
Duplicate entry '1' for key 'PRIMARY'
这是预期的行为。现在，你问了这个：
如果第18行成功执行并且第19行执行存在异常，那么由于第18行引起的更改应该是回滚。我怎么能这样做？
这就是这里发生的事情：
@Transaction(propagation = PROPAGATION_SUPPORTS)
public void updateDetails(User user) {
appDao.updateUserName(user); //line no 18
appDao.updateAddress(user); //line no 19
}
如果您使用PROPAGATION_SUPPORTS，那么如果没有启动任何事务，代码将在非事务性上下文中运行。这意味着，如果第19行抛出异常，第18行将不会回滚（假设事务未在之前启动）。
如果您希望第18行和第19行都在一个事务中，则应将传播更改为默认值（即PROPAGATION_REQUIRED），如果尚未启动，则会创建新事务。仅使用该更改，如果第19行引发异常，则第18行也将回滚。
所以只需改变传播：）
