基于hystrix的第一次请求都会报错 #38

Closed sail-y closed 5 years ago

sail-y commented 5 years ago

我是clone的最新的代码，也就是3.8.0-RC2来测试的，为了测试hystrix的效果，我对example的代码稍做了一点修改，下面我描述一下我遇到的问题。

依赖的修改：

<dependencies>
    <dependency>
        <groupId>com.nepxion</groupId>
        <!-- <artifactId>discovery-plugin-starter-eureka</artifactId> -->
            <artifactId>discovery-plugin-starter-consul</artifactId>
        <!-- <artifactId>discovery-plugin-starter-zookeeper</artifactId> -->
        <!--<artifactId>discovery-plugin-starter-nacos</artifactId>-->
    </dependency>

    <dependency>
        <groupId>com.nepxion</groupId>
            <artifactId>discovery-plugin-config-center-starter-apollo</artifactId>
        <!--<artifactId>discovery-plugin-config-center-starter-nacos</artifactId>-->
        <!-- <artifactId>discovery-plugin-config-center-starter-redis</artifactId> -->
    </dependency>

    <dependency>
        <groupId>com.nepxion</groupId>
        <artifactId>discovery-plugin-strategy-starter-service</artifactId>
    </dependency>

    <!-- 当服务用Hystrix做线程隔离的时候，才需要导入下面的包 -->
        <dependency>
        <groupId>com.nepxion</groupId>
        <artifactId>discovery-plugin-strategy-starter-hystrix</artifactId>
    </dependency>

    <!--<dependency>-->
        <!--<groupId>org.springframework.cloud</groupId>-->
        <!--<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>-->
    <!--</dependency>-->

    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-starter-client</artifactId>
    </dependency>
</dependencies>

代码的修改：

ARestImpl.java

@RequestMapping(path = "/rest", method = RequestMethod.POST)
@HystrixCommand(threadPoolKey = "example-b", commandKey = "example-b")
public String rest(@RequestBody String value) {
    value = doRest(value);
    value = restTemplate.postForEntity("http://discovery-springcloud-example-b/rest", value, String.class).getBody();

    LOG.info("调用路径：{}", value);

    return value;
}

BRestImpl.java

@RequestMapping(path = "/rest", method = RequestMethod.POST)
@HystrixCommand(threadPoolKey = "example-c", commandKey = "example-c")
public String rest(@RequestBody String value) {
    value = doRest(value);
    value = restTemplate.postForEntity("http://discovery-springcloud-example-c/rest", value, String.class).getBody();

    LOG.info("调用路径：{}", value);

    return value;
}

CRestImpl.java

@RequestMapping(path = "/rest", method = RequestMethod.POST)
@HystrixCommand(threadPoolKey = "service-c", commandKey = "service-c")
public String rest(@RequestBody String value) {
    value = doRest(value);

    LOG.info("调用路径：{}", value);

    return value;
}

配置的修改：

bootstrap.properties

spring.application.strategy.hystrix.threadlocal.supported=true

然后我在用postman进行首次访问的时候，得到了如下的错误：

然后我进行了第二次，第三次测试，则没有再出现这个错误，反复实验几次后，每次应用启动完成后，第一次都会报这个错误。

已经解决
