Question

我有SpringMVC / Hibernate Web应用程序。当我尝试更新其中一个条目时没有任何反应。我尝试使用以下代码更新条目：org.hibernate.Session.merge(object) 我没有任何例外。我启用mysql来记录收到的所有请求，在日志中我发现有更新语句，但在此之后有一个rollback显然取消了更新。这是mysql日志

168 Query SET sql_mode='STRICT_TRANS_TABLES' 168 Query SET autocommit=0 156 Query SET autocommit=0 156 Query select tasks0_.id as id1_0_0_, tasks0_.assigneeId as assignee7_0_0_, tasks0_.description as descript2_0_0_, tasks0_.dueDate as dueDate3_0_0_, tasks0_.name as name4_0_0_, tasks0_.shortName as shortNam5_0_0_, tasks0_.status as status6_0_0_ from tasks tasks0_ where tasks0_.id=2 156 Query select user0_.id as id1_1_0_, user0_.email as email2_1_0_, user0_.fullName as fullName3_1_0_, user0_.password as password4_1_0_, user0_.username as username5_1_0_ from users user0_ where user0_.id=1 156 Query update tasks set assigneeId=1, description='task1 desc', dueDate='2012-01-01', name='nameaddsaqqq1111111', shortName='task 1 shrt name', status='READY' where id=2 156 Query rollback 156 Query SET autocommit=1 168 Query commit 168 Query SET autocommit=1

我不知道什么可能导致回滚。有没有人有想法？

控制器的代码：

@Controller
public class TaskController {

@Autowired
private TasksService tasksService;

@RequestMapping(value = "/task/update", method = RequestMethod.POST)
    public ModelAndView editTask(@Valid Tasks task, BindingResult result) {

        if (result.hasErrors()) {
            return new ModelAndView("owners/createOrUpdateOwnerForm");
        } else {
            Tasks t = tasksService.findTaskById(task.getId());
            update(task, t);
            t.setName("addsaasddsa");

            tasksService.update(t);
            ModelAndView modelAndView = new ModelAndView("task/editOrCreate");
            modelAndView.addObject("task",
                    tasksService.findTaskById(task.getId()));
            return modelAndView;

        }
    }

服务代码：

public interface TasksService {

    public void update(Tasks task);

}

服务实施的代码：

@Transactional
@Service
public class TasksServiceImpl implements TasksService {

    @Autowired
    TaskDAO taskDao;


    @Override
    public void update(Tasks task) {
        taskDao.updates(task);
    }

}

DAO的代码：

public interface TaskDAO {

    public void updates(Tasks task);

}

DAO实施代码：

@Repository
public class TaskDAOImpl extends DbDaoImpl<Tasks> implements TaskDAO {


    @Override
    public void updates(Tasks task) {
        update(task);
    }
}

DbDaoImpl的代码：

import org.hibernate.SessionFactory;
import org.hibernate.Session;

public abstract class DbDaoImpl<T> implements Dao<T> {

@Autowired
    private SessionFactory factory;

    protected Session getSession() {
        return factory.getCurrentSession();
    }

@Override
    @SuppressWarnings("unchecked")
    public T update(final T entity) {
        return (T) getSession().merge(entity);
    }
}


public interface Dao<T> extends Serializable {

    T update(final T entity);
}

hibernate配置属性：

dataSource.driverClassName=com.mysql.jdbc.Driver
dataSource.url=jdbc\:mysql\://localhost\:3306/qwerty
dataSource.username=root
dataSource.password=root

hibernate.dialect=org.hibernate.dialect.MySQLDialect

JPA配置的代码：

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "com.task.tracker.DAO", "my.pack" } /*
                                                                             * basePackageClasses
                                                                             * =
                                                                             * Application

        config.setConnectionProperties(hibernateConfiguration());

        return config;

安全配置的代码：

@Configuration
@EnableWebMvcSecurity
class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public UserService userService() {
        return new UserService();
    }

    @Bean
    public TokenBasedRememberMeServices rememberMeServices() {
        return new TokenBasedRememberMeServices("remember-me-key",
                userService());
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new StandardPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.eraseCredentials(true).userDetailsService(userService());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/", "/favicon.ico", "/resources/**", "/signup")
                .permitAll().anyRequest().authenticated().and().formLogin()
                .loginPage("/signin").permitAll().failureUrl("/signin?error=1")
                .loginProcessingUrl("/authenticate").and().logout()
                .logoutUrl("/logout").permitAll()
                .logoutSuccessUrl("/signin?logout").and().rememberMe()
                .rememberMeServices(rememberMeServices())
                .key("remember-me-key");
        http.csrf().disable();
    }
}

应用程序配置：

@Configuration
@ComponentScan(basePackages = { "com.task.tracker.services", "com.task.tracker.DAO.impl" }, excludeFilters = @Filter({
        Controller.class, Configuration.class }))
class ApplicationConfig {

    @Bean
    public static PropertyPlaceholderConfigurer propertyPlaceholderConfigurer() {
        PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer();
        ppc.setLocation(new ClassPathResource("/persistence.properties"));
        return ppc;
    }

}

问题在于JpaConfig我有两个bean返回PlatformTransactionManager一个返回JpaTransactionManager而另一个返回HibernateTransactionManager。解决方案是删除JpaTransactionManager。

感谢所有评论此问题的人。
