springmvc多事務(wù)提交和回滾問題
更新時間:2024年09月27日 10:10:28 作者:正怒月神
本文介紹了Spring MVC中如何配置和使用多事務(wù)管理及回滾,重點內(nèi)容包括配置jdbc.properties文件,使用Spring Framework 5.3版本新增的CompositeTransactionManager,以及如何在相關(guān)方法上添加@Transactional注解
springmvc多事務(wù)提交和回滾
1.jdbc.properties
# mysql jdbc.driver=com.mysql.cj.jdbc.Driver jdbc.jdbcUrl=jdbc:mysql://192.168.1.xxx:3306/kintech_bo jdbc.user=root jdbc.password=root jdbc.initialPoolSize=3 jdbc.miniPoolSize=3 jdbc.maxPoolSize=200 jdbc.maxIdleTime=20 jdbc.idleConnectionTestPeriod=60 jdbc.sqlserver.initialPoolSize=1 jdbc.sqlserver.miniPoolSize=1 jdbc.sqlserver.maxPoolSize=200 jdbc.sqlserver.maxIdleTime=20 jdbc.sqlserver.idleConnectionTestPeriod=60 # sqlserver sqlserver.gica.driver= com.microsoft.sqlserver.jdbc.SQLServerDriver sqlserver.gica.jdbcUrl= jdbc:sqlserver://192.168.1.xxx:1433;DatabaseName=logisoft;useSSL=false sqlserver.gica.user= sa sqlserver.gica.password= sasa #hibernate config hibernate.dialect=org.hibernate.dialect.MySQLDialect hibernate.show_sql=false hibernate.format_sql=true #hibernate.hbm2ddl.auto =update hibernate.hbm2ddl.auto=none hibernate.cache.use_second_level_cache=false hibernate.cache.use_query_cache=false hibernate.cache.provider_class=net.sf.ehcache.hibernate.EhCacheProvider hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory
2.spring配置
重點:<!-- 配置ChainedTransactionManager -->
從Spring Framework 5.3版本開始,Spring提供了一個新的事務(wù)管理器實現(xiàn)類CompositeTransactionManager

3.添加@Transactional
相關(guān)方法都記得加上@Transactional
