我的弹簧工具套装中的项目有问题。 @Transactional注释不起作用。@Transactional不能在我的弹簧工具套装中工作
这里是我的项目结构: -
web.xml中: -
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>
<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Processes application requests -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
的servlet-context.xml中: -
<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />
<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
<context:component-scan base-package="com.project.dateandcrud" />
根上下文。 xml: -
<!-- Root Context: defines shared resources visible to all other web components -->
<context:property-placeholder location="classpath:datasource-cfg.properties" />
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${ds.driverClassName}" />
<property name="url" value="${ds.url}" />
<property name="username" value="${ds.username}" />
<property name="password" value="${ds.password}" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.project.dateandcrud.entity" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">validate</prop>
</props>
</property>
</bean>
<!-- Transaction Manager to make Transaction Support-->
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
我已经使用了DAOIMPL如下: - 当我不使用@Transactional注解我的项目工作正常
@Repository
public class ProfileDaoImpl implements ProfileDao {
@Autowired
private SessionFactory sessionFactory;
private Session session;
@Override
@Transactional
public void addProfile(Profile p) {
session = sessionFactory.openSession();
// session.beginTransaction();
session.save(p);
// session.getTransaction().commit();
session.close();
}
。但是当使用注释时它不起作用。
在我的servlet-context.xml或root-context.xml文件中是否有任何问题。
我曾尝试 <context:component-scan base-package="com.project.dateandcrud" />
这从selvlet-context.xml的迁入根的context.xml但也不能工作。
请建议我可能的错误。
这是什么意思它不工作?是否有任何异常弹出? –
@MaciejKowalski没有错误弹出窗口,只是它没有插入数据到数据库... – Space
