多個表上的Spring事務和回滾

Question

我正在努力使用 DAO 進行交易管理。 該場景是創建包含 quote_line 和客戶列表的新報價。 如果客戶不存在，則將其插入表客戶中。 我的代碼架構如下：

    @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
@EnableAutoConfiguration
@Configuration
@EnableTransactionManagement
@ComponentScan
public class Application {

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

}

//StatelessAuthenticationSecurityConfig.java
@EnableWebSecurity

public class StatelessAuthenticationSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    public StatelessAuthenticationSecurityConfig() {
        super(true);
    }

                .headers().cacheControl().and()
                .authorizeRequests()

                                .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;
    }
}

在調試模式下，我只有兩個變量：1- this（QuoteService）2-quote

這是日志：

    ...

如您所見，打印了消息“°°°°°°°°°°°°°°°°°°°行 44 已刪除”，但沒有 DELETE FROM hibernate 查詢的蹤跡。

此代碼不起作用：使用 customerDao 和 quoteLineDao 的事務不會將對象保留在數據庫中。 我認為propagation=Propagation.REQUIRED 將強制所有DAO 使用相同的會話，因此將執行不同的事務，如果發生錯誤，所有事務都將回滾。 我發現的唯一解釋（根據結果）是自動裝配的 DAO 使用不同的會話。 我嘗試了propagation=Propagation.SUPPORTS --> 事務已執行但我無法回滾，因為SUPPORTS 強制使用不同的會話。

你能解釋為什么這不起作用，我該如何糾正？

任何幫助將不勝感激！！！

謝謝！

Answer 1

更新我的答案：

1. 您希望您的“public Quote save(Quote quote)”方法是事務性的。
2. 當這個方法被調用時......交易開始於 TransactionInterceptor 並從代理“public Quote save(Quote quote)”被調用
3. 行“quoteLineDao.delete(new Long(44));” 工作正常
4. Line "System.out.println("°°°°°°°°°°°°°°°°°°°第 44 行刪除");" 工作正常
5. 行“quoteDao.save(quote);” 給出約束違反異常。 事務被標記為回滾
6. 您正在捕獲此異常並使用它而不是傳播異常
7. 方法“public Quote save(Quote quote)”將返回null，因為“return null;”行
8. 現在代碼到達事務攔截器，並且由於該攔截器沒有異常，它嘗試提交但事務已被標記為回滾，因此失敗。

解決方案：- 由於您的事務需要，您不能使用異常而是傳播異常。

改為跟隨。 添加了 throw 語句。

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;
}
