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

[shpodg]

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>

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。
