使用Spring引导运行Spring Integration RSocket示例时出错

我试图创建一个简单的Spring Boot应用程序来测试Rsocket的Spring集成

我将test文件夹中的示例代码从

spring integrarion rsocket

复制到我的spring引导应用程序中

pom.xml

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-rsocket</artifactId>
        </dependency>

        <dependency>

        <dependency>
            <groupId>org.springframework.integration</groupId>
            <artifactId>spring-integration-rsocket</artifactId>

主应用程序类

@springboot应用程序
公共类演示应用程序{
公共静态void main（字符串[]args）{
run（DemoApplication.class，args）；
}
}
@配置
类DemoIntegrationConfig{
@豆子

@豆子

公共集成流rsocketUpperCaseFlow（）{
返回积分流
.from（RSockets.inboundGateway（“/大写”））
.transform（（flux）->flux.map（String:：toUpperCase））

}

以及测试代码

@SpringBootTest
类DemoApplicationTests{
@自动连线
@限定符（“rsocketUpperCaseRequestFlow.gateway”）
专用函数rsocketUpperCaseFlowFunction；
@试验
void testRsocketUpperCaseFlows（）{
通量结果=此.rsocketUpperCaseFlowFunction.apply（通量.just（“a\n”、“b\n”、“c\n”））；
步骤验证程序。创建（结果）
.expectNext（“A”、“B”、“C”）
.verifyComplete（）；
}
}

当我运行测试时，它抛出异常：目标“/uppercase”没有处理程序

并清除application.properties中的配置

示例

RestController

@RestController
类Hello控制器{
@自动连线
@懒惰的
@限定符（“rsocketUpperCaseRequestFlow.gateway”）
专用函数rsocketUpperCaseFlowFunction；
@GetMapping（value=“hello”，products=MediaType.TEXT\u EVENT\u STREAM\u value）
公共流量大写（）{
返回rsocketUpperCaseFlowFunction.apply（通量仅为（“a”、“b”、“c”、“d”））；
}
}
