多个表上的Spring事务和回滚

Question

我正在使用DAO进行事务管理。场景是创建包含quote_line和客户列表的新报价。如果客户不存在，它将把它插入表客户中。我的代码是如下架构：

    @Entity
    @Table(name = "quote")
    public class Quote {
      @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
       //....properties
       @ManyToOne(fetch = FetchType.EAGER)
        @JoinColumn(name = "customer_id", nullable = true)
        private Customer customer;


        @OneToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH}, mappedBy = "quote")
        @Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
                org.hibernate.annotations.CascadeType.DELETE,
                org.hibernate.annotations.CascadeType.MERGE,
                org.hibernate.annotations.CascadeType.PERSIST,
                org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
        private Set<QuoteLine> quoteLines;

        //... methods
    }

    @Entity
    @Table(name = "quote_line")
    public class QuoteLine {

        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;

        //....properties


        @ManyToOne(fetch = FetchType.EAGER)
        @JoinColumn(name = "quote_id", nullable = false)
        private Quote quote;
        //... methods
    }

    public interface QuoteDao extends CrudRepository<Quote, Long> {
        //... methods
    }

    public interface QuoteLineDao extends CrudRepository<QuoteLineDao, Long> {
        //... methods
    }

    public interface CustomerDao extends CrudRepository<CustomerDao, Long> {
        //... methods
    }

    @Service
    public class QuoteService{

        @Autowired
        private QuoteDao quoteDao;

        @Autowired
        private QuoteLineDao quoteLineDao;

        @Autowired
        private CustomerDao customerDao;

        @Transactional(propagation=Propagation.REQUIRED, rollbackFor=Exception.class)
        public Quote save(Quote quote) {

            try{
                quoteLineDao.delete(new Long(44));
                System.out.println("°°°°°°°°°°°°°°°°°°Line 44 deleted");
                return  quoteDao.save(quote); 
            } catch(Exception e){
                Logger.getLogger(QuoteService.class).log(Logger.Level.FATAL, e);
            }
            return null;
        }
    }

//Application.java

public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

//StatelessAuthenticationSecurityConfig.java

                                .antMatchers("/api/**").hasRole("USER")
                                .antMatchers("/api/invoice/**").permitAll()

                                //defined Admin only API area
                .antMatchers("/api/admin/**").hasRole("ADMIN")

                                //defined Admin only API area
                .antMatchers("/api/superadmin/**").hasRole("SUPER_ADMIN")

                //allow anonymous GETs to API
                //.antMatchers(HttpMethod.GET, "/api/**").permitAll()



                //all other request need to be authenticated
                .anyRequest().hasRole("USER").and()             

                // custom JSON based authentication by POST of {"username":"<name>","password":"<password>"} which sets the token header upon authentication
                .addFilterBefore(new StatelessLoginFilter("/api/login", tokenAuthenticationService, userDetailsService, authenticationManager()), UsernamePasswordAuthenticationFilter.class)

                // custom Token based authentication based on the header previously given to the client
                .addFilterBefore(new StatelessAuthenticationFilter(tokenAuthenticationService), UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
                //auth.jdbcAuthentication().dataSource(null).usersByUsernameQuery("").authoritiesByUsernameQuery("");

    }

    @Override
    protected UserDetailsService userDetailsService() {
        return userDetailsService;
    }
}

在调试模式下，我只有两个变量：1-这（QuoteService）2-quote

这是th日志：

您可以注意到，消息“第44行删除”已打印，但没有从hibernate查询中删除的痕迹。

这段代码不起作用:使用customerDao和quoteLineDao的事务不会将对象持久化到数据库中。我以为传播=传播。REQUIRED将强制所有Dao使用相同的会话，因此将执行不同的事务，如果发生错误，所有事务都将回滚。我发现的唯一解释是自动连接的Dao使用不同的会话。我试过繁殖=繁殖。支持-

你能解释一下为什么这不起作用吗？我该如何纠正？

任何帮助将不胜感激！

谢谢！

Answer 1

更新我的答案：

1. 您希望您的“公共报价保存（报价报价）”方法是事务性的
2. 调用此方法时，事务在TransactionInterceptor中开始，并从代理中调用“公共报价保存（报价报价）”。
3. 行“quoteLineDao.delete（新长（44））工作正常
4. “系统输出打印”行（“删除第44行中的“°°”或“°”）工作正常
5. 行“quoteDao.save（quote）；”给出了约束冲突异常。事务被标记为回滚。
6. 您正在捕获并使用此异常，而不是传播此异常。
7. 方法“PublicQuote save（Quote Quote）”将返回null，因为行“return null；”
8. 现在代码到达事务拦截器，由于该拦截器没有异常，它尝试提交，但事务已经标记为回滚，因此失败

解决方案:-由于您的事务需要，您不能消费异常，而是传播异常。

改为以下内容。添加了throw语句。

try{
      quoteLineDao.delete(new Long(44));
      System.out.println("°°°°°°°°°°°°°°°°°°Line 44 deleted");
      return  quoteDao.save(quote); 
} catch(Exception e){
      Logger.getLogger(QuoteService.class).log(Logger.Level.ERROR, e);
      throw e;
}
