1、關(guān)于spring中配置hibernate申明事務(wù)無(wú)效的問(wèn)題在spring配置hibernate的申明事務(wù)的時(shí)候,發(fā)覺(jué)事務(wù)控制向來(lái)都不好使，關(guān)鍵配置如下： spring的mvc的配置如下： contt:component-scan base-package= com.going / context:annotation-config / !- to requestmap process on type level and method level - bean ' target='_blank'>mvc.annotation.defaultannotationhan

2、dlermapping / bean > property name= messageconverters list ref bean= marshallingconverter / ref bean= jsonconverter / ref bean= atomconverter / /list /property /bean !- xml converter - bean = marshallingconverter > consuctor-arg ref= jaxbmarshaller / property name= pportmediatypes value= appli

3、ion/xml / /bean bean id= jaxbmarshaller > property name= classestobebound list value com.going.sample.domain.employee /value value com.going.sample.domain.employeelist /value /list /property /bean !- json converter - bean id= jsonconverter > property name= supportedmediatypes value= applicatio

4、n/json / /bean !- atom converter - bean id= atomconverter > property name= supportedmediatypes value= application/atom+xml / /bean !- client - bean id= resttemplate > property name= messageconverters list ref bean= marshallingconverter / ref bean= jsonconverter / ref bean= atomconverter / /lis

5、t /property /bean !- viewer - !- xmlview - bean id= xmlview > constructor-arg ref= jaxbmarshaller / /bean !- jsonview - bean id= jsonview > bean > property name= mediatypes map entry key= json value= application/json / entry key= xml value= application/xml / entry key= html value= text/html

6、 / /map /property property name= viewresolvers list bean > bean > bean id= viewresolver ' target='_blank'>sedviewresolver property name= viewclass value= org.springframework.web.servlet.view.jstlview / property name= prefix value= /web-inf/view/jsp/ / property name= suffix value

7、= .jsp / /bean /list /property /bean applicationcontext.xml的配置如下： !- 數(shù)據(jù)源的配置 - bean id= datasource ' target='_blank'>cp.basicdatasource destroy-method= close p:driverclassname= $jdbc.driverclassname p:url= $jdbc.databaseurl p:username= $jdbc.username p:password= $jdbc.password / !- hib

8、ernate工廠類的配置 - bean id= sessionfactory ' target='_blank'>rm.hibernate3.localsessionfactorybean property name= datasource ref= datasource / property name= configlocation value classpath:hibernate.cfg.xml /value /property property name= configurationclass value org.hibernate.cfg.annotat

9、ionconfiguration /value /property property name= hibernateproperties props prop key= hibernate.dialect $jdbc.dialect /prop prop key= hibernate.show_sql true /prop prop key= hibernate.jdbc.fetch_size 25 /prop prop key= hibernate.jdbc.batch_size 50 /prop !- dev - prop key= hibernate.show_sql true /pro

10、p prop key= hibernate.format_sql true /prop prop key= hibernate.generate_istic fae /prop !- cache - !-代表是否用法查詢緩存，這里不用法，由于普通而言查詢緩存的命中率并不是很高，所以我們沒(méi)有 須要為每一個(gè)用戶的查詢緩存它的數(shù)據(jù)，所以這里設(shè)為false- prop key= hibernate.cache.use_query_cache false /prop !-代表用法hibernate的二級(jí)緩存- prop key= hibernate.cache.use_second_level_cach

11、e false /prop !- create db table - prop key= hibernate.hbm2l.auto up /prop /props /property /bean bean id= transactionmanager > property name= sessionfactory ref= sessionfactory / /bean 在以上配置的狀況下，無(wú)論我的service怎么配置transactional注解，都無(wú)效，如： service transactional public class contactserviceimpl implement

12、s contactservice autowired private contactrepository contactrepository; public contactrepository getcontactrepository() return contactrepository; public void contactrepository(contactrepository contactrepository) this.contactrepository = contactrepository; transactional(propagation=propagation.requi

13、red) public void addcontact(contact contact) contactrepository.addcontact(contact); public list contact listcontact() return contactrepository.listcontact(); transactional(readonly = true) public void removecontact(string id) contactrepository.removecontact(id); 即使我在removecontact辦法中添加只讀控制readonly =

14、true,相關(guān)刪除實(shí)體操作一樣能夠正常執(zhí)行。 后面在網(wǎng)上搜了一些信息，問(wèn)題在于spring在實(shí)例化controller類時(shí)，spring會(huì)自動(dòng)把關(guān)聯(lián)的service（此service已做了transaction事務(wù)注解）類實(shí)例化，此時(shí)事務(wù)并未生效，導(dǎo)致transaction注解無(wú)效，事務(wù)未被注冊(cè)。解決方法如下： 將spring的mvc配置中的以下信息： context:component-scan base-package= com.going / 修改為： context:component-scan base-package= com.going context:ilude-filter type= annotation ession= org.springframework.stereotype.controller / context:exclude-filter type= annotation expression= org.springframework.stereotype.service / /context:component-scan 表示容器在用法注解加載控制層時(shí),不實(shí)例化控制層以外的組件。 除此以外，也將applicationcontext.xml文件中添加如下的配置： context:
