About java-development-manual

java-development-manual is a reference skill for Java developers, organizing Alibaba Java Development Manual rules across seven areas. It supports code reviews, project setup, and troubleshooting with concise rules and links to detailed guidance.

Key features

  1. 01Rules across seven Java development areas
  2. 02Severity levels for requirements
  3. 03Naming and coding conventions
  4. 04Exception, logging, and security guidance
  5. 05MySQL and project structure rules
  6. 06Design and unit testing references

Use cases

  1. 01Review Java code conventions
  2. 02Plan a new project structure
  3. 03Check database and SQL practices
  4. 04Investigate exceptions or concurrency issues

Java开发手册(嵩山版)

概述

本手册基于阿里巴巴Java开发手册(嵩山版),将规约分为7个维度。规约按约束力强弱分为:

级别含义说明
【强制】必须遵守违反可能导致严重问题
【推荐】建议遵守提升代码质量和可维护性
【参考】可选择性采纳根据实际情况判断

章节导航

根据需求选择对应章节的详细规约:

章节适用场景详细文档
编程规约命名、格式、OOP、并发、集合处理coding-convention.md
异常日志错误码、异常处理、日志规范exception-log.md
单元测试测试用例、覆盖率、Mockunit-test.md
安全规约SQL注入、XSS、CSRF、脱敏security.md
MySQL数据库建表、索引、SQL、ORMmysql.md
工程结构分层架构、依赖管理、服务器project-structure.md
设计规约UML、设计模式、设计原则design.md

快速参考

命名规范速查
// 类名:UpperCamelCase
public class UserService { }
public class UserDO { }      // DO/DTO/VO例外

// 方法名/变量:lowerCamelCase
private String userName;
public void getUserById() { }

// 常量:全大写+下划线
public static final int MAX_RETRY_COUNT = 3;

// 包名:全小写
package com.company.project.service;
禁止事项速查
禁止原因
拼音命名可读性差
魔法值难以维护
SELECT *性能和可维护性
Executors创建线程池可能OOM
字符串拼接SQL注入风险
finally中return丢失try返回值
foreach中removeConcurrentModificationException
必须事项速查
必须原因
覆写方法加@Override避免签名错误
表必备三字段id, create_time, update_time
敏感数据脱敏隐私保护
参数校验安全防护
ThreadLocal回收避免内存泄漏
日志用占位符性能优化
异常处理速查
// 正确的异常处理
try {
    // 业务逻辑
} catch (SpecificException e) {
    logger.error("操作失败, 参数: {}", params, e);
    throw new BusinessException("用户友好提示", e);
} finally {
    // 资源关闭(JDK7+ try-with-resources)
}
数据库速查
-- 建表必备
CREATE TABLE example (
    `id` bigint unsigned NOT NULL AUTO_INCREMENT,
    `create_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
    `update_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 索引命名
-- 主键: pk_字段名
-- 唯一: uk_字段名
-- 普通: idx_字段名
并发处理速查
// 线程池创建
ThreadPoolExecutor executor = new ThreadPoolExecutor(
    corePoolSize,
    maximumPoolSize,
    keepAliveTime,
    TimeUnit.SECONDS,
    new LinkedBlockingQueue<>(queueCapacity),
    new ThreadFactory() {
        private AtomicInteger counter = new AtomicInteger(1);
        public Thread newThread(Runnable r) {
            return new Thread(r, "worker-" + counter.getAndIncrement());
        }
    },
    new ThreadPoolExecutor.CallerRunsPolicy()
);

// ThreadLocal使用
try {
    threadLocal.set(value);
    // 业务逻辑
} finally {
    threadLocal.remove();  // 必须回收
}
