Spring MVC + hibernate service层和dao层

Spring MVC + hibernate service层和dao层 方法头上都加上@Transactional会识别哪个

service层:
@Override
@Transactional
public Future save(UserVO userVO) {
this.myUserDao().saveUser(user);
...

dao层:
@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public void saveUser(User user) {
save(user);
...

1个回答

这个无关识别哪个问题。 比如你上面的service层 propagation为Propagation.REQUIRED,而dao层的propagation=Propagation.REQUIRES_NEW。dao层执行的时候重新生成一个新的事务,service层的事务将会挂起,当dao层方法执行完后,service挂起的事务将被激活。
实际中,不会dao层和service层都加事务,一般都加载service层。

关于MVC中的Service层能不能写查询条件给Dao层

学校里的项目都是很规矩的在Dao层写很多很细碎的方法,实习的时候发现公司的dao层 很神奇的全部继承一个base类,baseImpl类中提供了oid sql hql qbc的查询方法 但是所有这些 都没有具体的查询条件,需要service层将hql sql 的查询语句 以及oid和qbc的条件对象通过参数的 形式传给Dao,乍一看这样的方法比在学校写的时候简便太多了,但是细想好像破坏了封装的 特性,不知道service层写查询条件这样的做做法是否妥当呢?

hibernate Spring save指令无法保存

使用了save指令 但是控制台没有输出insert语句 也没有报错 没有保存数据 ```@Entity public class Payroll{ @Id @GeneratedValue private long pid; private long sid; //结账日期 private Timestamp date; //累结 private double totalSum; //结余 private double balance; //伙食费用 private double boardWages; //扣款 private double deduct; //欠款 private double debt; ///预支 private double advance; //薪水细则 @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="pid") private List<PayrollRow> payrollRow = new ArrayList<PayrollRow>(); //省略GETTER SETTER } ``` ``` @Entity public class PayrollRow { @Id @GeneratedValue private long prid; private String style_number; private String process; private int count; private double cost; private double amount; // } ``` DAO层 ``` @Repository public class PayrollDAOImpl implements PayrollDAO{ @Autowired SessionFactory sessionFactory; public boolean save(Payroll p) { // TODO Auto-generated method stub try { System.out.println("info"+sessionFactory.getCurrentSession().save(p)); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); return false; } return true; } public boolean saveRow(PayrollRow pr){ // TODO Auto-generated method stub try { System.out.println("info"+sessionFactory.getCurrentSession().save(pr)); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); return false; } return true; } } ``` service层 ``` @Service @Transactional public class PayrollServiceImpl implements PayrollService { @Autowired PayrollDAOImpl payrollDAO ; public boolean save(Payroll payroll){ List<PayrollRow> pwl = payroll.getPayrollRow(); for (int i = 0;i<pwl.size();i++) { payrollDAO.saveRow(pwl.get(i)); System.out.println("info "+i); } return payrollDAO.save(payroll); } } ``` 配置文件 ``` <!-- 支持注解 --> <mvc:annotation-driven /> <!--自动装配DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter --> <mvc:default-servlet-handler /> <!-- 设置自动扫描的路径,用于自动注入bean 这里的路径与自己的项目目录对应--> <!-- 扫描controller路由控制器 --> <context:component-scan base-package="pres.uiiooo.controller" /> <context:component-scan base-package="pres.uiiooo.daoimpl,pres.uiiooo.serviceimpl" /> <!-- 视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="suffix" value=".jsp" /> <!-- 视图文件类型 --> <property name="prefix" value="/WEB-INF/views/" /> <!-- 视图文件的文件夹路径 --> </bean> </beans> ``` ``` <!-- JNDI(通过Tomcat)方式配置数据源 --> <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> --> <!-- 引入属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- 配置数据源 这里class可以使用不同的驱动--> <bean name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc_driverClassName}" /> <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> </bean> <!-- 配置hibernate session工厂 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="hibernateProperties"> <props> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="current_session_context_class">thread</prop> </props> </property> <!-- 自动扫描注解方式配置的hibernate类文件 --> <property name="packagesToScan"> <list> <!-- 此处与entity实体路径对应 --> <value>pres.uiiooo.model</value> </list> </property> </bean> <!-- 配置事务管理器 --> <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 注解方式配置事物 --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans> ``` 其他的DAO层save是可用的 但是这个不行 应该是涉及到事务管理配置 还有一对多配置方面的问题 求大佬解决 谢谢谢谢了!!!

tomcat + hibernate + spring 运行 内存溢出

本人最近做的一个项目中,需要使用hiberante映射将近400张表,相应的spring也要配置400个dao manger,tomcat启动后内存占用非常大,页面上有的时候随便点两下服务就挂了,请问有什么解决的方法?

@RequestMapping(params = "executeSearch") @Transactional public String executeSearch(HttpServletRequest request) { //测试事物控制。 infoService.test(); return "info/search"; } ServiceImpl.java public void test(){ try { infoDAO.test(); } catch (Exception e) { e.printStackTrace(); } } Service.java @Transactional public void test(); DaoImpl.java @Transactional public void test() { try { String sql =

!conditions.get(i).equals("")){ query.setParameter(i, conditions.get(i)); } } } return query.executeUpdate(); } catch (RuntimeException e) { throw e; }finally{ System.out.println(getSessionFactory().getCurrentSession().beginTransaction().isActive()); } } 整体代码是这样的,在运行daoImpl.java中test()方法的时候执行第一条SQL时会提交事物,直接修改数据库中的值,执行第二条SQL时会报错,理论上应该都不提交事物。但实际上第一条执行了之后就提交事物了,不知道是我框架问题还是我写的问题,求大神帮忙指出问题所在。万分感谢! ```

在Spring MVC框架下 一个@Repository的dao中 可以同时注入hibernateTemplate和jdbcTemplate吗

在java timer定时器中调用dao层会报错

现在在做一个web项目,使用spring+springMVC+hibernate框架, 问题描述: 项目中有一个扫描的功能,分即时任务、定时任务、周期任务三种,即时任务已经实现了,现在使用java.util.Timer、java.util.TimerTask类做定时任务,重写TimerTask的run方法,在run方法中调用之前已经没有问题的即时任务扫描方法。每次运行定时任务时,会卡在dao层方法的调用上,因为在即时任务的扫描方法中调用了dao层的数据操作方法,报错“No Session found for current thread”。 即时任务的执行流程:前台提交即时任务扫描请求->控制器调用service层的立即扫描方法startImmediateTask(); 定时任务的执行流程:前台提交定时任务扫描请求->控制器调用service层的定时扫描方法startTimerTask()->调用立即扫描方法startImmediateTask()。 下面附上代码和配置文件,请各位大牛帮忙解决啊! service层代码 ```java /** * 开始定时扫描任务 * @param blTask */ public void startTimerTask(final BLTask blTask) { Date startDate = blTask.getStartTime(); TimerTask task = new TimerTask() { @Override public void run() { // 调用扫描方法 startImmediateTask(blTask); } }; Timer timer = new Timer(); timer.schedule(task, startDate); } /** * 开始即时扫描任务 * @param blTask */ public void

spring+hibernate+atomikos 实现JTA分布式事务时自定义事务隔离级别无效

因为需要对两个数据库同时操作并且放在同一个事务中,所以采用了atomikos去实现JTA分布式事务。数据库用的是SQL Server2014 . 现在的问题是,事务提交回滚,一切都正常,但是没有按照设定好的事务隔离级别给数据库表加锁。比如service中的save方法 设定的是SERIALIZABLE隔离级别,测试时查询数据库表隔离级别,并未按照预期加锁。 以下是配置文件,请大神给解惑一下。
