在带有JPA和Spring 3的Spring MVC中，没有任何事务正在进行中

Question

我无法使用springmvc中注入的entitymgr将数据持久化到数据库中。我试过很多类似的问题，但似乎没有一个答案能解决我的问题。

我的配置如下：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="...">
<import resource="config-context.xml"/>
<context:annotation-config />
<tx:annotation-driven />
<context:component-scan base-package="org.springbyexample.orm.jpa.inheritance.dao" />

                <constructor-arg value="com.package..*"></constructor-arg>  
            </bean>
        </property>               
</bean>
<bean id="transactionInterceptorIkConf"  
        class="org.springframework.transaction.interceptor.TransactionInterceptor">

        </property>  
</bean> 
</beans>

在config-context.xml中：

<?xml  version="1.0" encoding="UTF-8"?>
<beans ...>
<context:property-placeholder location="..." 
        ignore-unresolvable="true" order="1" ignore-resource-not-found="true"/>       
<context:property-placeholder location="classpath:config.properties"                                    
        order="2"/> 
<context:component-scan base-package="com.package" >
    <context:exclude-filter type="regex" expression=".*controller.[^.]*"/>
</context:component-scan>

</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" p:entityManagerFactory-ref="emf" autowire="byName"/>
</beans>

在mvc-dispacher-servlet.xml 中

<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
<context:component-scan base-package="com.package" >
    <context:include-filter type="regex" expression=".*controller.[^.]*"/>
</context:component-scan>
<mvc:resources mapping="/resources/**" location="/WEB-INF/static/" />
<mvc:annotation-driven />
<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/pages/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>
</beans>

内部web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app ...>
<display-name>demo-app</display-name>
<!-- Spring context -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<!-- Spring MVC -->
<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        
    <init-param>
        <param-name>contextConfiglocation</param-name>
        <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>

现在我有一个控制器

@Controller
@RequestMapping("/main")
public class MainController {
    @Autowired
    private OneService service; //with getters and setters
    @RequestMapping(value = "/url", method = RequestMethod.POST, headers = { "Content-type=application/json" })
    public @ResponseBody Data move(@RequestBody Data data) {
        getService().doSomething(data);
    }
}

和服务

@Service
public class OneService {
    @Autowired
    private OneDao dao;

    @Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW, rollbackFor = { IkfBusinessException.class })
    public void doSomething(Data data) {
        //Do the actual logic inside transaction
    }
    @PersistenceContext(unitName = "conf-persistence")
    @Override
    protected void setEntityManager(EntityManager em) {
        this.em = em;
    }
}

我遇到了以下错误：javax.persistence.TransactionRequiredException：当我从控制器调用服务时，没有正在进行的事务。

但当我用Bootstrap类运行它时，它可以正常工作。

我想我的MVC配置有问题。

Answer 1

我有一个可能的解决方案：

我在mvc servlet中更改了组件扫描，如：

<context:component-scan base-package="com.package.controller"/>

只添加我的控制器，因为"context:include filter"不包括专门指定的包。

有了这个配置，它现在就可以工作了。也许还有更好的配置。

不管怎样，谢谢大家抽出时间，如果你还有什么建议可以回复。
