Question

我的Spring Tool Suit项目存在问题。 @Transactional注释不起作用。

这是我的项目结构： -

web.xml中： -

console.log("clicked")

servlet的context.xml中： -

handleClickWithFunction

根context.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>

我使用DAOIMPL如下： -

<!-- 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" />

当我不使用@Transactional注释时，我的项目工作正常。但是当使用注释时，它不起作用。

我的servlet-context.xml或root-context.xml文件中是否有任何问题。

我试过移动 {strong}从 selvlet-context.xml  <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>  <tx:annotation-driven transaction-manager="transactionManager"/> <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>到 root-context.xml ，但这也不起作用。

请告诉我可能的错误。

Answer 1

请勿尝试自己打开/关闭休眠$new_array = array_intersect_key($your_array, /* main array*/ array_flip( /* to be extracted */ array('nickname', 'first_name','last_name') ) );，让session处理此问题：

spring-tx

将@Transactional public void addProfile(Profile p) { final Session session = sessionFactory.getCurrentSession(); session.save(p); }从<annotation-driven/>移至您的servlet-context.xml配置。

这可以解决您的问题。

Answer 2

以下是我找到的解决方案....只需将<tx:annotation-driven transaction-manager="transactionManager"/>从 root-context.xml 移动到 servlet-context.xml 即可。

@Transactional在我的Spring Tool Suit中不起作用
