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 行执行成功并且第 19 行执行出现异常，则应回滚由于第 18 行引起的更改。我该怎么做。？
改变了::
@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。请帮我解决这个问题......
最佳答案
只是抛出异常。当抛出异常时，JTX代理将捕获它并标记事务以进行回滚。
此行为在 AnnotationTxAdvice 中定义class，虽然这不是你真正应该关心的事情 :)
编辑
快速概览告诉我发生异常是因为您有重复的主键条目:
Duplicate entry '1' for key 'PRIMARY'
这是预期的行为。现在，你问这个:
if line 18 is executed successfully and there is exception on line 19 execution then changes due to line 18 should be rollback. how can I do that?
这是这里发生的事情:
@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 那么如果没有事务启动，代码将在非事务上下文中运行。这意味着，如果第 19 行抛出异常，第 18 行将不会回滚(假设之前未启动事务)。
如果您希望第 18 行和第 19 行都在一个事务中，您应该将传播更改为默认值(即 PROPAGATION_REQUIRED)，如果尚未开始，这将创建新的事务。只有那个变化，如果第 19 行抛出异常，第 18 行也会回滚。
所以只要改变传播:)
关于java - jodd框架使用@transaction注解时如何回滚事务？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31881825/
