以如下依赖为示例：

<dependency>
     <groupId>org.springframework.ai</groupId>
     <artifactId>spring-ai-starter-mcp-server-webflux</artifactId>
     <version>1.1.0</version>
 </dependency>

yaml配置

spring:
  ai:
    mcp:
      server:
        protocol: STATELESS
        name: xxx-streamable-mcp-server
        version: 1.0.0
        type: SYNC
        instructions: "xxx"
        resource-change-notification: true
        tool-change-notification: true
        prompt-change-notification: true

StatelessToolCallbackConverterAutoConfiguration

无状态工具执行服务自动装配类

初始化工具tool

org.springframework.ai.mcp.server.common.autoconfigure.StatelessToolCallbackConverterAutoConfiguration#syncTools

将tool作为参数，创建McpStatelessAsyncServer

org.springframework.ai.mcp.server.common.autoconfigure.McpServerStatelessAutoConfiguration#mcpStatelessSyncServer
io.modelcontextprotocol.server.McpServer.StatelessSyncSpecification#build
io.modelcontextprotocol.server.McpStatelessAsyncServer#McpStatelessAsyncServer（设置handler）

查询工具列表处理类

io.modelcontextprotocol.server.McpStatelessAsyncServer#toolsListRequestHandler

McpServerStatelessWebFluxAutoConfiguration

McpServerStatelessWebFluxAutoConfiguration 作用是将指定的endpoint暴露出去

@AutoConfiguration(
    before = {McpServerStatelessAutoConfiguration.class}
)
@ConditionalOnClass({McpSchema.class})
@EnableConfigurationProperties({McpServerStreamableHttpProperties.class})
@Conditional({McpServerStdioDisabledCondition.class, McpServerStatelessAutoConfiguration.EnabledStatelessServerCondition.class})
public class McpServerStatelessWebFluxAutoConfiguration {
    @Bean
    @ConditionalOnMissingBean
    public WebFluxStatelessServerTransport webFluxStatelessServerTransport(@Qualifier("mcpServerObjectMapper") ObjectMapper objectMapper, McpServerStreamableHttpProperties serverProperties) {
        return WebFluxStatelessServerTransport.builder().jsonMapper(new JacksonMcpJsonMapper(objectMapper)).messageEndpoint(serverProperties.getMcpEndpoint()).build();
    }

    @Bean
    @ConditionalOnMissingBean(
        name = {"webFluxStatelessServerRouterFunction"}
    )
    public RouterFunction<?> webFluxStatelessServerRouterFunction(WebFluxStatelessServerTransport webFluxStatelessTransport) {
        return webFluxStatelessTransport.getRouterFunction();
    }
}

RouterFunction用的很巧妙
