@Transactional 注释不起作用springboot

Question

我正在使用带有 mongodb 的 springboot 2.3.0。 @Transactional注释对我不起作用。 如果出现任何异常，它无法回滚事务。 ps：使用 mongoTemplate 它正在工作。

任何帮助将不胜感激。

我的 controller class：

@PostMapping(value = "/employee/{employeeId}")
public String createEmployee(@PathVariable(value = "employeeId") String employeeId, @RequestBody EmployeePayload payload) {
    
    employeeService.createEmployee(employeeId, payload);
    return "employee successfully added";
}

我的服务Impl class

 @Override @Transactional(rollbackFor = {ArithmeticException.class}) public void createEmployee(String employeeId, EmployeePayload payload) { Employee employee = new Employee("1", "Robert", "24"); Document mongoDocument = new Document(); mongoTemplate.getConverter().write(employee, mongoDocument); MongoDatabaseFactory mongoDatabaseFactory = new SimpleMongoClientDatabaseFactory(properties.getUri() + properties.getDataBase() + properties.getDbFilter()); MongoDatabaseUtils.getDatabase(properties.getDataBase(), mongoDatabaseFactory).getCollection("employee").insertOne(mongoDocument); System.out.println(7 / 0); //To throw an exception }

我的 MongoConfig class

@Configuration public class MongoDBConfig {

    @Bean
    MongoTransactionManager transactionManager(MongoDatabaseFactory dbFactory) {
        return new MongoTransactionManager(dbFactory);
    } 
}

您缺少@EnableTransactionManagement注释。
