关于配置mcp服务端sse-message-endpoint和sse-endpoint的注意点

在spring ai配置mcp服务时，这里的pom配置如下(alibaba的配置不用管)：

application.yml配置如下:

java 复制代码

spring:
  application:
    name: mcp-server
  ai:
    mcp:
      server:
        name: mcp-server1
        version: 1.0.0
        type: SYNC
        # sse消息端点路径
        sse-message-endpoint: /api/v1/mcp/message
        # sse端点路径
        sse-endpoint: /api/v1/sse
        # url访问前缀
#        base-url: /api/v1
        stdio: false

server:
  port: 8085

这里可以看到有一个base_url的配置，这个配置目前感觉是没有多大的作用，我在客户端访问MCP服务端的时候这个base_url的配置主要作用在sse-message-endpoint链接前缀，但是当客户端连接上sse-endpoint端点的时候访问的/api/v1/mcp/message出现404的错误，但是当把base_url注释掉，直接把sse-message-endpoint端点修改为/api/v1/mcp/message就可以正常访问了，客户端的配置如下:

java 复制代码

spring:
  ai:
    mcp:
      client:
        mcp-server:
           url: http://localhost:8085
           sse-endpoint: /api/v1/sse
