2. 业务服务

pom.xml 相关 Maven包

    <dependencies>
      <dependency>
        <groupId>com.codingapi.txlcn</groupId>
        <artifactId>txlcn-tc</artifactId>
	    <version>5.0.2.RELEASE</version>

        <artifactId>txlcn-txmsg-netty</artifactId>
	    <version>5.0.2.RELEASE</version>
      </dependency>
    </dependencies>

基本配置

/** 环境文件 application.properties*/

# hystrix time out 
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=18000
ribbon.ConnectTimeout=16000
ribbon.ReadTimeout=16000
#Mysql

# 是否启动LCN负载均衡策略(优化选项，开启与否，功能不受影响)
tx-lcn.ribbon.loadbalancer.dtx.enabled=true
# 默认之配置为TM的本机默认端口
tx-lcn.client.manager-address=127.0.0.1:8070
# 开启日志,默认为false

tx-lcn.logger.driver-class-name=${spring.datasource.driver-class-name}
tx-lcn.logger.jdbc-url=${spring.datasource.url}
tx-lcn.logger.username=${spring.datasource.username}
tx-lcn.logger.password=${spring.datasource.password}

启动文件

@EnableDistributedTransaction
@EnableTransactionManagement
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class UserApp {
    public static void main(String[] args) {
        SpringApplication.run(UserApp.class, args);
    }

}

有需要事物的方法上方都需加上两个 注释 @LcnTransaction 和 @Transactional

例

    @LcnTransaction
    @Transactional
    public void create(final String name, final Integer age, final String status, final String type) {
        eventClient.create(name, type);
        orderClient.create(name, status);
        userDao.create(name, age);
    }
