grails回滚db操作时出现某些错误
|
我有一项将大量数据保存到db的服务。
使用MYSQL
我已经习惯了
Domain1.withTransaction {text->
def domain1=//Create my domain object to save
if(!domain1.save()){
domain1.errors.each {
println it
}
throw new RuntimeException(\'unable to save domain1\')
}
Domain2.withTransaction {text->
def domain2=//Create my domain object to save
if(!domain2.save()){
domain2.errors.each {
println it
}
throw new RuntimeException(\'unable to save domain2\')
}
没有找到相关结果

class SomeService { static transactional = false def serviceMethod() { def domain1=//Create my domain object to save def domain2=//Create my domain object to save domain1.save(failOnError:true) domain2.save(failOnError:true) } }中配置的dataSource { dialect= org.hibernate.dialect.MySQLInnoDBDialect ... }盛虱

闭包放入闭包中，因此Domain2事务中的错误将回滚Domain1和Domain2事务 像这样Domain1.withTransaction { //.... Domain2.withTransaction { //.... } }购藏盗码韦
Domain1.withTransaction {text-> def domain1=//Create my domain object to save if (!domain1.save()) { domain1.errors.each { println it } throw new RuntimeException(\'unable to save domain1\') } def domain2=//Create my domain object to save if (!domain2.save()) { domain2.errors.each { println it } throw new RuntimeException(\'unable to save domain2\') } }
