Spring事务和多表回滚
Spring事务和多表回滚
我在使用DAO进行事务管理方面遇到了困难。情景是创建一个包含报价行列表和一个客户的新报价。如果客户不存在,它将在客户表中插入。我的代码结构如下:
@Entity @Table(name = "quote") public class Quote { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //....属性 @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 SetquoteLines; //... 方法 } @Entity @Table(name = "quote_line") public class QuoteLine { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //....属性 @ManyToOne(fetch = FetchType.EAGER) @JoinColumn(name = "quote_id", nullable = false) private Quote quote; //... 方法 } public interface QuoteDao extends CrudRepository { //... 方法 } public interface QuoteLineDao extends CrudRepository{ //... 方法 } public interface CustomerDao extends CrudRepository { //... 方法 } @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; } } @EnableAutoConfiguration @Configuration @EnableTransactionManagement @ComponentScan public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } @EnableWebSecurity @Configuration @EnableTransactionManagement @Order(1) public class StatelessAuthenticationSecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Autowired private TokenAuthenticationService tokenAuthenticationService; public StatelessAuthenticationSecurityConfig() { super(true); } @Override protected void configure(HttpSecurity http) throws Exception { http .exceptionHandling().and() .anonymous().and() .servletApi().and() .headers().cacheControl().and() .authorizeRequests() //允许匿名资源请求 .antMatchers("/").permitAll() .antMatchers("/favicon.ico").permitAll() .antMatchers("/resources/**").permitAll() //允许匿名登录POST请求 .antMatchers(HttpMethod.POST, "/api/login").permitAll() //允许匿名客户POST请求 //.antMatchers(HttpMethod.POST, "/api/customer/**").permitAll() .antMatchers("/api/**").hasRole("USER") .antMatchers("/api/invoice/**").permitAll() //定义只有管理员才能访问的API区域 .antMatchers("/api/admin/**").hasRole("ADMIN") //定义只有超级管理员才能访问的API区域 .antMatchers("/api/superadmin/**").hasRole("SUPER_ADMIN") //允许匿名GET请求的API //.antMatchers(HttpMethod.GET, "/api/**").permitAll() //其他请求需要身份验证 .anyRequest().hasRole("USER").and() //自定义基于JSON的身份验证 .addFilterBefore(new StatelessLoginFilter("/api/login", tokenAuthenticationService, userDetailsService, authenticationManager()), UsernamePasswordAuthenticationFilter.class) //自定义基于令牌的身份验证 .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- this(QuoteService)
2- quote
以下是日志:

正如您所注意到的,消息“°°°°°°°°°°°°°°°°°°Line 44 deleted”被打印出来,但没有关于DELETE FROM hibernate查询的痕迹。
这段代码无法工作:使用customerDao和quoteLineDao的事务不会将对象持久化到数据库中。
我认为propagation=Propagation.REQUIRED会强制所有DAO使用相同的会话,因此不同的事务将被执行,如果发生错误,所有事务都将被回滚。
我找到的唯一解释(关于结果)是自动装配的DAO使用不同的会话。
我尝试了propagation=Propagation.SUPPORTS --> 事务被执行,但我无法回滚,因为SUPPORTS强制使用不同的会话。
您能解释为什么这不起作用,以及如何更正这个问题吗?
非常感谢!
(Spring事务和多表回滚)
在更新我的答案时:
- 您希望"public Quote save(Quote quote)"方法具有事务性。
- 当调用此方法时...事务在TransactionInterceptor中开始,并从代理中调用"public Quote save(Quote quote)"。
- 行"quoteLineDao.delete(new Long(44));"工作正常。
- 行"System.out.println("°°°°°°°°°°°°°°°°°°Line 44 deleted");"工作正常。
- 行"quoteDao.save(quote);"出现约束违规异常。事务标记为回滚。
- 您捕获并消耗了此异常,而不是传播异常
- 方法"public Quote save(Quote quote)"将返回null,因为行"return null;"
- 现在代码到达事务拦截器,因为此拦截器没有异常,它尝试提交,但事务已标记为回滚,因此失败。
解决方案:您不应该消耗异常,而应传播异常,因为您的事务需求。
更改如下,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; }

感谢您的回答。我尝试过了,但仍然不起作用。我编辑了我的问题,添加了有关application.java和StatelessAuthenticationSecurityConfig.java的更多说明,以及日志。谢谢。
您能贴出完整的堆栈跟踪吗?
是的,它正在工作。注意。在类被**注释时,没有必要添加**。我认为这是在内部方法调用时自动完成的(!需要检查!)。再次感谢。
是的,由于Spring Boot的原因,我之前没有注意到。如果这个答案对您有用,请接受并点赞吗?
我正在使用Spring Boot创建一个API,用于更新两个表,因此如果更新之一失败,我需要一个回滚的方法。然而,如果在异常处理程序中消耗异常,意味着事务失败,我还需要API向用户返回错误消息。在这种情况下,我该怎么办?
我的问题的解决方案可以在这里找到。它与异常处理程序无关,而是与Spring无法拦截内部方法调用有关。
