springcloud用户指南(使用者JDK必须为1.8)

  • 在你的实现项目中引入jar包,并在实现接口上添加: @Tcc(confirmMethod = "confirm", cancelMethod = "cancel")confirmMethod,cancelMethod对应为的方法名称
     <dependency>
          <groupId>com.hmily.tcc</groupId>
          <artifactId>hmily-tcc-springcloud</artifactId>
          <version>{you version}</version>
      </dependency>
  • 配置applicationContext.xml,如下所示,如果具体的配置问题请参照配置详解
<!-- Aspect 切面配置,是否开启AOP切面-->
  <aop:aspectj-autoproxy expose-proxy="true"/>
  <!--扫描框架的包-->
  <context:component-scan base-package="com.hmily.tcc.*"/>
  <!--启动类属性配置-->
   <bean id="hmilyTransactionBootstrap" class="com.hmily.tcc.core.bootstrap.HmilyTransactionBootstrap">
        <property name="serializer" value="kryo"/>
        <property name="recoverDelayTime" value="120"/>
        <property name="retryMax" value="3"/>
        <property name="scheduledDelay" value="120"/>
        <property name="scheduledThreadMax" value="4"/>
        <property name="repositorySupport" value="db"/>
        <property name="tccDbConfig">
            <bean class="com.hmily.tcc.common.config.TccDbConfig">
                <property name="url"
                          value="jdbc:mysql://192.168.1.98:3306/tcc?useUnicode=true&amp;characterEncoding=utf8"/>
                <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
                <property name="username" value="root"/>
                <property name="password" value="123456"/>
            </bean>
        </property>
    </bean>
  • 在消费方引入jar包,如果消费方也需要进行tcc事务,同上配置

  • 在FeignClient上的调用方法上加上@Tcc注解,并指定配置configuration,具体配置可参考以下:

@Configuration
public class MyConfiguration {

    @Bean
    @Scope("prototype")
    public Feign.Builder feignBuilder() {
        return Feign.builder()
                .requestInterceptor(new TccRestTemplateInterceptor())
                .invocationHandlerFactory(invocationHandlerFactory());
    }

    @Bean
    public InvocationHandlerFactory invocationHandlerFactory() {
        return (target, dispatch) -> {
            TccFeignHandler handler = new TccFeignHandler();
            handler.setTarget(target);
            handler.setHandlers(dispatch);
            return handler;
        };
    }

    @Bean
    Request.Options feignOptions() {
        return new Request.Options(/**connectTimeoutMillis**/1 * 5000, /** readTimeoutMillis **/1 * 5000);
    }

    @Bean
    Retryer feignRetryer() {
        return Retryer.NEVER_RETRY;
    }
}
