spring - grails.gorm.transactions.Transactional不回滚

Question

我在使用以下内容回滚服务层中的事务时遇到问题:

Grails 3.3.8

GORM 6.1.10。发布

我有以下服务方法:

import grails.gorm.transactions.Transactional

@Transactional(rollbackFor = Exception.class)
class TestingService {

    void testServiceMethod(List<Factory> factories) {
        try {
            factories.each {
                if (it.name == 'second') {
                    throw new Exception('second')
                }
                it.testField = 'Edited'
                it.save()
                println(it.name + ' saved')
            }
        } catch (Exception e) {
            println('Exception Caught ' + e)
        }
    }
}

我还创建了以下集成测试:

@Integration
@Rollback
class TestServiceIntSpec extends Specification {

    @Autowired
    TestingService testingService

    def setup() {
    }

    def cleanup() {
    }

    void "test something"() {
        when:
        Factory factoryOne = new Factory(name: "first").save(flush: true)
        Factory factoryTwo = new Factory(name: "second").save(flush: true)
        List<Factory> factories = [factoryOne, factoryTwo]
        testingService.testServiceMethod(factories)

        then:
        factoryOne.testField == null
        factoryTwo.testField == null
    }
}

我也有以下 Controller 方法:

class TestController {

    TestingService testingService

    def index() {
        Factory factoryOne = new Factory(name: "first").save(flush: true)
        Factory factoryTwo = new Factory(name: "second").save(flush: true)
        List<Factory> factories = [factoryOne, factoryTwo]
        testingService.testServiceMethod(factories)
        println "First Factory: $factoryOne.testField"
        println "First Factory: $factoryTwo.testField"
        render 'Check Console'
    }
}

我本以为测试会通过，因为我认为在抛出新异常后，事务将回滚，但是it.testField仍然存在吗？另外，当我对TestController执行ping操作时，它会将factoryOne.testField输出为“已编辑”。我是否从文档中正确地理解了这一点？

“服务启用事务划分，这是定义将哪些方法变为事务性的声明方式。要在服务上启用事务，请使用事务转换:
结果是所有方法都包装在事务中，并且如果方法抛出异常(包括Checked或Runtime异常)或Error，则会发生自动回滚。”

我也看不到我在做什么，而与此其他Stackoverflow答案不同:

可以通过拉出以下Github项目并运行/factory/factory/src/integration-test/groovy/com/mycompany/myapp/TestServiceIntSpec.groovy或ping / factory / factory / grails-app / controllers / com /来重新创建此问题。 mycompany / myapp / TestController.groovy

在您的catch块中，您需要重新引发异常。

catch (Exception e) {
        println('Exception Caught ' + e)
        throw e;
}

我所看到的问题是，异常永远不会逸出该方法。
