alibaba-rsocket-spring-boot-starter-1.0.0.M1问题反馈 #47

Open shpodg opened 4 years ago

shpodg commented 4 years ago
  1. 自动化配置RSocketListenerAutoConfiguration中,当properties中没有配置rsocket.port时，以下表达式会返回true，导致应用启动了监听处理逻辑。建议改为 ${rsocket.port:0}!=0 
    @Configuration
@ConditionalOnExpression("'${rsocket.port}'!='0'")
public class RSocketListenerAutoConfiguration {
  2. 没有生成spring-autoconfigure-metadata.properties文件导致RSocketAutoConfiguration中@ConditionalOnClass加载了类而报错 
    @Bean
@ConditionalOnClass(PrometheusMeterRegistry.class)
public MetricsService metricsService(PrometheusMeterRegistry meterRegistry) {
    return new MetricsServicePrometheusImpl(meterRegistry);
}

    文档建议添加如下依赖

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-autoconfigure-processor</artifactId>
        <optional>true</optional>
    </dependency>

    参考文档 报错信息如下

已经调整啦。 目前rsocket broker强依赖micrometer-registry-prometheus做Metrics，已经调整为非optional啦。

  <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
 </dependency>

io.micrometer micrometer-registry-prometheus

版本1.13.0 PrometheusMeterRegistry 类包路径变了 io.micrometer.prometheus 变成 io.micrometer.prometheusmetrics 了，该怎么兼容呢

我会发布一个新的版本，进行兼容。
