Question

我想为每个REST查询创建一个事务，REST查询由Jackson 2动态解析的JSON数据组成。在从JSON数据“解析”对象实例化期间，我通过Spring Repository对数据库进行一些输入。当一些数据库约束不被尊重时，一切都正常工作@Transactional不捕获异常并且不回滚。我怎么能解决这个问题，上面你找到了代码：

UploadData类包含一些实体类，以便解析JSON数据，并将数据保存在数据库中。

Controller.java

@Transactional(rollbackFor=Exception.class)
@RequestMapping(value = "/uploaddata", method = RequestMethod.POST, consumes = "application/json; charset=UTF-8")
public Reponse uploaddata(@RequestBody UploadData post) throws JsonProcessingException {
    if (messages != null) {
        return new Reponse(-1, messages);
    }

    try {
        return new Reponse(0, post);
    } catch (Exception e) {
        return new Reponse(1, Static.getErreursForException(e));
    }
}

AppConfig.java

@EnableAutoConfiguration
@ComponentScan(basePackages = { "com.test" })
@EnableJpaRepositories(basePackages = { "com.test.repositories" })
@EntityScan(basePackages = { "com.test.entities" })
@EnableTransactionManagement
public class AppConfig {


    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
         HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean();
         factory.setEntityManagerFactory(emf);
         return factory;
    }
}

UploadData.java

public class UploadData {
    @JsonProperty("ADDEDDATA")
    private AddedData ADDEDDATA;

}

@Transactional不会在Spring Boot中捕获Jackson异常
