Spring XML configuration-based transactions (14)

Refer to the previous declarative transaction example: http://www.cnblogs.com/caoyc/p/5632198.html

We have made the corresponding changes. In DAO and in each class in the service, remove all annotation labels. Then provide a setxxx () method for each field

Finally, configure the Applicationcontext.xml file. The contents are as follows:

1<?XML version= "1.0" encoding= "UTF-8"?>2<Beansxmlns= "Http://www.springframework.org/schema/beans"3Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"4Xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"5Xmlns:context= "Http://www.springframework.org/schema/context"6Xmlns:tx= "Http://www.springframework.org/schema/tx"7Xsi:schemalocation= "Http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd8Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd9Http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd10Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd ">111213<!--Read Db.properties configuration information-14<Context:property-placeholderLocation= "Classpath:db.properties"/>1516<!--Configuring a C3P0 data source-17<BeanId= "DataSource"Class= "Com.mchange.v2.c3p0.ComboPooledDataSource">18<PropertyName= "User"Value= "${jdbc.user}"/>19<PropertyName= "Password"Value= "${jdbc.password}"/>20<PropertyName= "Driverclass"Value= "${jdbc.driverclass}"/>21st<PropertyName= "Jdbcurl"Value= "${jdbc.jdbcurl}"/>22</Bean>2324<!--Configure a JdbcTemplate to manipulate the database-25<BeanId= "JdbcTemplate"Class= "Org.springframework.jdbc.core.JdbcTemplate">26<PropertyName= "DataSource"Ref= "DataSource"/>27</Bean>2829<!--Configure DAO-30<BeanId= "Bookdao"Class= "Com.proc.dao.BookDao">31<PropertyName= "JdbcTemplate"Ref= "JdbcTemplate"/>32</Bean>33<BeanId= "Storedao"Class= "Com.proc.dao.StoreDao">34<PropertyName= "JdbcTemplate"Ref= "JdbcTemplate"/>35</Bean>36<BeanId= "Userdao"Class= "Com.proc.dao.UserDao">37<PropertyName= "JdbcTemplate"Ref= "JdbcTemplate"/>38</Bean>3940<!--Configure Service-41<BeanId= "Bookshopservice"Class= "Com.proc.service.BookShopServiceJdbcImps">42<property name= "Bookdao" ref= "Bookdao"/>43 <property name= "Storedao" ref= " Storedao "/>44 <property name=" Userdao "ref=" Userdao "/>45 </bean>46 <!--configuration transaction manager-->48 <bean Id= "TransactionManager" class= "Org.springframework.jdbc.datasource.DataSourceTransactionManager" >49 < Property Name= "DataSource" ref= "DataSource" ></property>50 </bean>51 <!--Configure transaction properties-->53 <TX: Advice id= "Advice" >54 <tx:attributes>55 <tx:method name= "get*" read-only= "true"/>56 <tx:method name = "find*" read-only= "true"/>57 <tx:method name= "*"/>58 </tx:attributes>59 </tx:advice>60 --Configure the entry point for the transaction: AOP cut-in-->62 <aop:config>63 <!--configuration Cut-in expression-->64 <aop:pointcut expression= "Execution (* Com.proc.service.*.* (..)) " Id= "Pointcut"/>65 <aop:advisor pointcut-ref= "pointcut" advice-ref= "Advice" ></aop:advisor>66 </ aop:config>67 </beans> 

This way, the XML-based transactions are well-configured.

Code Analysis:

Transactions take the form of AOP. So you need to configure an AOP pointcut. Specify which classes and methods to adopt for transactions
