[Java知识库]seata分布式XA模式-nacoa环境

前提：invoke调用order和store，因为是一个demo没有做太细的处理，有一些重复maven依赖其实可以创建一个父类统一管理。

invoke.serviceImpl

@Service
public class InvokeServiceImpl implements InvokeService {

    @Autowired
    private OrderClientApi orderClientApi;

    @Autowired
    private StoreClientApi storeClientApi;

    @GlobalTransactional
    @Transactional
    @Override
    public int invokeHandler() {
        System.out.println("invokeHandler" + RootContext.getXID());
        String s = orderClientApi.addOrder();
        int i = 1 / 0;
        String s1 = storeClientApi.addStore();
        if ("success".equals(s) && "success".equals(s1)){
            return 1;
        }
        return 0;
    }
}

invoke的application.yml

server:
  port: 8001

spring:
  application:
    name: zongdapao-invoke
  cloud:
    nacos:
      discovery:
        group: SEATA_GROUP

seata:
  data-source-proxy-mode: XA
  registry:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      username: nacoa
      password: nacos
      group: SEATA_GROUP
      application: seata-server
  tx-service-group: seata-zzx
  service:
    vgroup-mapping:
      seata-zzx: default
  enabled: true
  config:
    type: nacos
    nacos:
      data-id: seataServer.properties
      server-addr: 127.0.0.1:8848
      group: SEATA_GROUP
      username: nacos
      password: nacos

order和store的application.yml

server:
  port: 8801

spring:
  application:
    name: zongdapao-order
  datasource:
    url: jdbc:mysql://localhost:3306/zzxmysql01?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
  cloud:
    nacos:
      discovery:
        group: SEATA_GROUP

mybatis:
  mapper-locations:
    - classpath:dao/*.xml
    - classpath*:com/**/dao/*.xml

seata:
  data-source-proxy-mode: XA
  registry:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      username: nacoa
      password: nacos
      group: SEATA_GROUP
      application: seata-server
  tx-service-group: seata-zzx
  service:
    vgroup-mapping:
      seata-zzx: default
  enabled: true
  config:
    type: nacos
    nacos:
      data-id: seataServer.properties
      server-addr: 127.0.0.1:8848
      group: SEATA_GROUP
      username: nacos
      password: nacos

接下来配置一下seata，我用的版本是1.4.2，需要向nacos上传两个配置文件


注意一下，第一张图更改为seata-zzx之后，要创建一个Data ID为service.vgroupMapping.seata-zzx的配置文件，配置内容是后面的default，也就是第二个配置文件。
下面说一下我遇到的问题：

java.lang.NoSuchMethodError: org.springframework.beans.factory.ListableBeanFactory.getBeanProvider(Ljava/lang/Class;Z)Lorg/springframework/…

这个错是jar包冲突；

java.lang.NoSuchMethodException: PropertySet.getBooleanReadableProperty(java.lang.Stri)

这个是mysql的版本问题，要选择8.0.11，我选择了以上的也不行。

XID为null问题

加依赖

<dependency>
	<groupId>com.alibaba.cloud</groupId>
	<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
	<version>2.2.5.RELEASE</version>
</dependency>

打印一下XID是否不为null或者不相等

System.out.println("store" + RootContext.getXID());

～有写错的或者有更优雅的写法记得@ 我～
