收益：60-80% 编译速度提升
- 文件:
idea64.vmoptions - 关键配置:
-Xms4g -Xmx8g # 大内存配置 -XX:+UseG1GC # G1垃圾收集器 -XX:MaxGCPauseMillis=200 # 低延迟GC -XX:+TieredCompilation # 分层编译 - 为什么收益最大: 您的项目有162个类，需要大量内存和高效的GC
2. Maven并行构建 ⭐⭐⭐⭐⭐
收益：50-70% 构建时间减少
- 配置: 在
pom.xml中已优化 - 关键参数:
mvn compile -T 4C # 4核并行编译 -Dmaven.test.skip=true # 跳过测试
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.1.2</version>
<configuration>
<argLine>-Dfile.encoding=UTF-8 -Xmx1024m</argLine>
<!-- 根据打包环境执行对应的@Tag测试方法 -->
<groups>${profiles.active}</groups>
<!-- 排除标签 -->
<excludedGroups>exclude</excludedGroups>
<!-- 并行执行测试 -->
<parallel>methods</parallel>
<threadCount>4</threadCount>
<!-- 跳过测试（开发环境） -->
<skipTests>${maven.test.skip}</skipTests>
</configuration>
</plugin>- 为什么收益大: 多模块项目天然适合并行构建
3. Maven仓库镜像优化 ⭐⭐⭐⭐
收益：30-50% 依赖下载速度提升
- 文件:
settings.xml - 关键配置: 使用阿里云、华为云镜像
<?xml version="1.0" encoding="UTF-8"?>

4. IDEA编译器设置 ⭐⭐⭐⭐
收益：20-40% 增量编译速度提升
- 设置路径: File → Settings → Build → Compiler
- 关键配置:
✅ Build project automatically ✅ Compile independent modules in parallel Compiler heap size: 4096 MB - 为什么收益大: 大型项目需要智能的增量编译
5. 代码检查优化 ⭐⭐⭐
收益：15-25% 响应速度提升
- 设置路径: File → Settings → Editor → Inspections
- 禁用不必要的检查: 拼写检查、未使用变量等
- 为什么收益中等: 减少IDEA后台处理负担
6. 文件监控优化 ⭐⭐⭐⭐⭐
路径: File → Settings → Appearance & Behavior → System Settings
关键配置：
- ✅ Use “safe write” (save changes to a temporary file first)
- Maximum heap size: 4096 MB
- Maximum number of threads: 8
- Background tasks: 限制为4个
文件监控排除：
# 排除不需要监控的目录
node_modules/
target/
.idea/
*.log
*.tmp
dist/
build/7. 索引优化 ⭐⭐⭐⭐⭐
路径: File → Settings → Editor → General → Code Completion
关键配置：
- Autopopup in (ms): 1000 (延迟自动完成)
- Show suggestions as you type: 关闭
- Insert selected suggestion by pressing space, dot, or other context-dependent keys: 关闭
索引排除：
路径: File → Settings → Project → Project Structure → Modules
- 排除
target/目录 - 排除
node_modules/目录 - 排除
dist/目录
8. 实时检查优化 ⭐⭐⭐⭐
路径: File → Settings → Editor → Inspections
禁用实时检查：
- Spelling → Typo → 关闭
- Java → Declaration redundancy → 全部关闭
- Java → Control flow issues → 关闭
- Java → Data flow issues → 关闭
- Spring → Spring Core → 关闭实时检查
