# Cursor 编译优化配置指南

## 1. Cursor 基础配置优化

### 1.1 工作区设置
在项目根目录创建 `.vscode/settings.json`：

```json
{
  "java.configuration.runtimes": [
    {
      "name": "JavaSE-21",
      "path": "D:\\jdk",
      "default": true
    }
  ],
  "java.compile.nullAnalysis.mode": "disabled",
  "java.autobuild.enabled": false,
  "java.maxConcurrentBuilds": 8,
  "java.import.maven.enabled": true,
  "java.import.gradle.enabled": false,
  "java.configuration.maven.userSettings": "C:\\Users\\{username}\\.m2\\settings.xml",
  "maven.executable.path": "D:\\maven3.9\\bin\\mvn.cmd",
  "maven.terminal.useJavaHome": true,
  "maven.terminal.customEnv": [
    {
      "environmentVariable": "MAVEN_OPTS",

    "**/target/**": true,
    "**/node_modules/**": true,
    "**/logs/**": true
  }
}
```

### 1.2 Java扩展配置
在 `.vscode/settings.json` 中添加Java相关配置：

```json
{
  "java.server.launchMode": "Standard",
  "java.sources.organizeImports.starThreshold": 99,
  "java.sources.organizeImports.staticStarThreshold": 99,

      },
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen"
    }
  ]
}
```

## 3. Cursor AI 功能优化

### 3.1 AI 代码补全配置

## 10. 故障排除

### 10.1 常见问题
1. **Java Language Server启动失败**
   - 检查Java路径配置
   - 清理工作区缓存：`Ctrl+Shift+P` -> `Java: Reload Projects`

2. **Maven依赖无法解析**
   - 检查Maven配置路径
   - 执行：`Ctrl+Shift+P` -> `Java: Reload Projects`

3. **编译错误**
   - 检查JDK版本是否正确
   - 清理target目录：`mvn clean`

### 10.2 性能优化建议
1. 定期清理工作区缓存
2. 关闭不必要的扩展
3. 调整Java Language Server内存
4. 使用SSD存储项目文件

## 使用建议

1. **首次打开项目**：
   - 等待Java Language Server初始化完成
   - 执行 `Java: Reload Projects` 确保依赖正确加载
   - 运行 `Maven: Clean Compile` 验证编译

2. **日常开发**：
   - 使用快捷键快速编译和运行
   - 利用AI代码补全提升效率
   - 定期清理缓存和临时文件

3. **调试技巧**：
   - 使用断点调试复杂业务逻辑
   - 利用条件断点提升调试效率
   - 使用远程调试连接运行中的应用
