确定是否需要配置环境变量
检查你的 FastMCP 连接。如你使用的 JsonConfig 示例所示,你需要配置以下环境变量到连接界面:NODE_ENVMAVEN_REPO(可选)JAVA_HOME(可选)CFR_PATH(可选)
配置
NODE_ENV环境变量- 推荐设置为
production,以减少日志并获得更优性能。 - 如需调试,可设置为
development。
- 推荐设置为
配置
MAVEN_REPO环境变量(可选)- 该变量为 Maven 本地仓库路径。
- 如果未设置,默认路径为
~/.m2/repository(Windows则通常为C:/Users/你的用户名/.m2/repository)。 - 如需指定其他仓库,填写绝对路径,例如:
D:/maven/repository。
配置
JAVA_HOME环境变量(可选)- 该变量为 Java 安装路径,用于调用内部反编译器(CFR)。
- 如果未设置,会使用 PATH 环境中的
java命令。 - 建议填写具体 JDK 路径,例如:
C:/Program Files/Java/jdk-11。
配置
CFR_PATH环境变量(可选)- 如你希望指定自定义的 CFR jar 包路径,可填写此项。
- 通常无需设置,服务已自带默认版本。
填写环境变量到 FastMCP 界面
- 打开 FastMCP 的 ENVs 设置界面(通常通过“Install Now”按钮进入)。
- 将上述变量及其值按需填写到“新增环境变量”表单中。
保存并启动服务
- 完成环境变量添加后,保存设置并启动 MCP Server 连接。服务即会自动检测配置和依赖,无需额外操作。
示例填写:
| 环境变量名 | 推荐值 | 说明 |
|---|---|---|
| NODE_ENV | production | 运行环境 |
| MAVEN_REPO | D:/maven/repository | Maven仓库路径(可选) |
| JAVA_HOME | C:/Program Files/Java/jdk-11 | JDK路径(可选) |
| CFR_PATH | /your/custom/path/cfr.jar | CFR工具路径(可选) |
如不确定部分参数,可只设置 NODE_ENV,保持其他默认。
