MCP java 服务开发问题记录

1.服务搭建报错如下:

json 复制代码

{
  "mcpServers": {
    "my-weather-server": {
      "disabled": false,
      "timeout": 30,
      "type": "stdio",
      "command": "java",
      "args": [
        "-jar",
        "E:/workspace/mcp/target/mcp-server-demo-0.0.1-SNAPSHOT.jar"
      ],
      "env": {
        "spring.main.web-application-type": "none",
        "spring.main.banner-mode": "off"
      }
    }
  }
}

本地是可以直接启动的, 可以使用java -jar的方式启动.

然后:

按照这个帖子的配置方式就好了...

按照这个配置即可. 
{
  "mcpServers": {
    "weather-starter-webmvc-server": {
      "command": "java",
      "args": [
        "-Dspring.ai.mcp.server.stdio=true",
        "-Dspring.main.web-application-type=none",
        "-Dlogging.pattern.console=",
        "-jar",
        "E:/workspace/mcp/target/mcp-server-demo-0.0.1-SNAPSHOT.jar"
      ]
    }
  }
}

改完后, 就连上了.
