@事务性注释springboot不起作用

Question

我正在使用MongoDB的springboot 2.3.0。@transactional注释对我不起作用。如果发生异常，则无法回滚事务。

任何帮助都将得到高度赞赏。

我的控制器类：

@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serviceImpl类

 @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);
     getCollection("employee").insertOne(mongoDocument);                
     System.out.println(7/0); //To throw an exception
 }  

我的MongoConfig类

@Configuration public class MongoDBConfig {

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

Answer 1

缺少@EnableTransactionManagement批注。
