SpringJpa事务巨坑被踩下 The given id must not be null!

[rent] 2019-02-22 18:09:41,751 ERROR [DubboServerHandler-172.20.30.57:20880-thread-18] com.company.rent.platform.service.dubbo.RentDubboExceptionHandler.aroudMethod(63) | dubbo service has a rentDubboException that is The given id must not be null!; nested exception is java.lang.IllegalArgumentException: The given id must not be null!.

上面这段错误是dubbo的接口的service在save时总数报错，而同样的接口在一般rest接口的service的save保存可以成功。

Connection is read-only. Queries leading to data modification are not allowed

当我解决dubbo的事务没有办法提交时，发现一般的rest的service的save保存一致提示上面的错误。

到此刻：一头两个大；

原因就是事务配置这块有问题，怎么搞呢？

为了调试dubbo接口顺便查找了dubbo如何本地调试，在reference中加入：url="dubbo://localhost:20881"，就能解决。原本的dubbo2.5.3被我升级到了2.6.0。

搞了3天终于解决这两块问题，一定要记录一下此次踩的坑；

场景

把一个传统tomcat方式运行的项目改造成了springboot方式运行，需要重新配置数据源、事务、dubbo、spring、springmvc等等工作。

项目最终运行环境：springboot1.5.2\dubbo2.6.0\spring4.3.5\springdatajpa1.10.5。

最终代码配置

SpringApplication配置

@SpringBootApplication
@Import(SpringContextHolder.class)
@ComponentScan(basePackages = {"com.company"},excludeFilters = { @ComponentScan.Filter(value = Controller.class)})
@ServletComponentScan({"com.company.rent.platform"})
@PropertySource(value = "classpath:application.properties",ignoreResourceNotFound = true)
@ImportResource({"classpath:dubbo-consumer.xml","classpath:dubbo-producer.xml"})
@EnableTransactionManagement
public class RentApplication extends SpringBootServletInitializer {

    static ConfigurableApplicationContext cac;

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(RentApplication.class);
    }

    public static void main(String[] args){
        SpringApplication app = new SpringApplicationBuilder(RentApplication.class).build();
        cac = app.run(args);
    }
}
