|
|
||||
|
## 通用部署流程 |
||||
|
|
||||
|
无论 Windows 还是 Mac，基本步骤一致： |
||||
|
|
||||
|
``` |
||||
|
1. 初始化 MySQL 数据库 |
||||
|
2. 修改 db.properties 数据库连接配置 |
||||
|
3. mvn clean package 打包 |
||||
|
4. 复制 WAR 到 Tomcat/webapps |
||||
|
5. 启动 Tomcat |
||||
|
6. 浏览器访问 http://localhost:8080/student-management/ |
||||
|
``` |
||||
|
|
||||
|
### 1. 初始化数据库 |
||||
|
|
||||
|
```bash |
||||
|
mysql -u root -p < src/main/resources/db_init.sql |
||||
|
``` |
||||
|
|
||||
|
### 2. 修改数据库配置 |
||||
|
|
||||
|
编辑 `src/main/resources/db.properties`： |
||||
|
|
||||
|
```properties |
||||
|
jdbc.driver=com.mysql.cj.jdbc.Driver |
||||
|
jdbc.url=jdbc:mysql://localhost:3306/student_db?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&useSSL=false |
||||
|
jdbc.username=root |
||||
|
jdbc.password=你的密码 |
||||
|
``` |
||||
|
|
||||
|
> 修改后需重新执行 `mvn clean package`。 |
||||
|
|
||||
|
### 3. 编译打包 |
||||
|
|
||||
|
```bash |
||||
|
mvn clean package |
||||
|
``` |
||||
|
|
||||
|
成功后 WAR 包路径： |
||||
|
|
||||
|
``` |
||||
|
target/student-management.war |
||||
|
``` |
||||
|
|
||||
|
### 4. 访问地址 |
||||
|
|
||||
|
``` |
||||
|
http://localhost:8080/student-management/ |
||||
|
``` |
||||
|
|
||||
|

## Windows 部署指南 |
||||
|
|
||||
|
### 安装 JDK 并配置 JAVA_HOME |
||||
|
|
||||
|
1. 安装 JDK（如 `C:\Program Files\Java\jdk-21`） |
||||
|
2. `Win + R` → 输入 `sysdm.cpl` → **高级** → **环境变量** |
||||
|
3. 新建系统变量： |
||||
|
- 变量名：`JAVA_HOME` |
||||
|
- 变量值：`C:\Program Files\Java\jdk-21`（按实际路径填写） |
||||
|
4. 编辑 `Path`，新增：`%JAVA_HOME%\bin` |
||||
|
5. 新开 cmd 验证： |
||||
|
|
||||
|
```cmd |
||||
|
echo %JAVA_HOME% |
||||
|
java -version |
||||
|
``` |
||||
|
|
||||
|
### 安装 Tomcat |
||||
|
|
||||
|
1. 下载 Tomcat 9：https://tomcat.apache.org/download-90.cgi |
||||
|
2. 选择 **64-bit Windows zip**，解压到如 `D:\apache-tomcat-9.0.98` |
||||
|
|
||||
|
### 部署 WAR |
||||
|
|
||||
|
**方法一：资源管理器** |
||||
|
|
||||
|
1. 复制 `target\student-management.war` |
||||
|
2. 粘贴到 `D:\apache-tomcat-9.0.98\webapps\` |
||||
|
|
||||
|
**方法二：PowerShell** |
||||
|
|
||||
|
```powershell |
||||
|
Copy-Item "D:\codefiles\javaweb-homework\student-management\target\student-management.war" ` |
||||
|
"D:\apache-tomcat-9.0.98\webapps\" |
||||
|
``` |
||||
|
|
||||
|
### 启动 / 停止 Tomcat |
||||
|
|
||||
|
```cmd |
||||
|
:: 启动（需先设置 JAVA_HOME，见下方临时方案） |
||||
|
D:\apache-tomcat-9.0.98\bin\startup.bat |
||||
|
|
||||
|
:: 停止 |
||||
|
D:\apache-tomcat-9.0.98\bin\shutdown.bat |
||||
|
``` |
||||
|
|
||||
|
**临时设置 JAVA_HOME 后启动（未配环境变量时）：** |
||||
|
|
||||
|
```cmd |
||||
|
set JAVA_HOME=C:\Program Files\Java\jdk-21 |
||||
|
set JRE_HOME=C:\Program Files\Java\jdk-21 |
||||
|
cd /d D:\apache-tomcat-9.0.98\bin |
||||
|
startup.bat |
||||
|
``` |
||||
|
|
||||
|
--- |
||||
|
|
||||
|
## Mac M1 部署指南 |
||||
|
|
||||
|
### 安装依赖（Homebrew） |
||||
|
|
||||
|
```bash |
||||
|
# 安装 Homebrew（如未安装） |
||||
|
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" |
||||
|
|
||||
|
# 安装 JDK（ARM64 原生版本） |
||||
|
brew install openjdk@17 |
||||
|
|
||||
|
# 配置 JAVA_HOME（Apple Silicon 路径） |
||||
|
echo 'export JAVA_HOME="/opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk/Contents/Home"' >> ~/.zshrc |
||||
|
echo 'export PATH="$JAVA_HOME/bin:$PATH"' >> ~/.zshrc |
||||
|
source ~/.zshrc |
||||
|
|
||||
|
# 验证 |
||||
|
java -version |
||||
|
echo $JAVA_HOME |
||||
|
|
||||
|
# 安装 Maven |
||||
|
brew install maven |
||||
|
|
||||
|
# 安装 MySQL |
||||
|
brew install mysql |
||||
|
brew services start mysql |
||||
|
|
||||
|
# 安装 Tomcat 9 |
||||
|
brew install tomcat@9 |
||||
|
``` |
||||
|
|
||||
|
> **Intel Mac** 用户：Homebrew 前缀为 `/usr/local` 而非 `/opt/homebrew`，JDK 路径类似 `/usr/local/opt/openjdk@17/...`。 |
||||
|
|
||||
|
### 初始化数据库（Mac） |
||||
|
|
||||
|
```bash |
||||
|
# 首次安装 MySQL 后设置 root 密码（按提示操作） |
||||
|
mysql_secure_installation |
||||
|
|
||||
|
# 导入数据 |
||||
|
cd /path/to/student-management |
||||
|
mysql -u root -p < src/main/resources/db_init.sql |
||||
|
``` |
||||
|
|
||||
|
### 编译打包（Mac） |
||||
|
|
||||
|
```bash |
||||
|
cd /path/to/student-management |
||||
|
mvn clean package |
||||
|
``` |
||||
|
|
||||
|
### 部署 WAR 到 Tomcat（Mac） |
||||
|
|
||||
|
**Homebrew 安装的 Tomcat 9：** |
||||
|
|
||||
|
```bash |
||||
|
# Tomcat 目录（M1 默认） |
||||
|
TOMCAT_HOME="/opt/homebrew/opt/tomcat@9/libexec" |
||||
|
|
||||
|
# 复制 WAR |
||||
|
cp target/student-management.war "$TOMCAT_HOME/webapps/" |
||||
|
|
||||
|
# 启动 Tomcat |
||||
|
brew services start tomcat@9 |
||||
|
|
||||
|
# 停止 Tomcat |
||||
|
brew services stop tomcat@9 |
||||
|
|
||||
|
# 查看日志 |
||||
|
tail -f "$TOMCAT_HOME/logs/catalina.out" |
||||
|
``` |
||||
|
|
||||
|
**手动解压的 Tomcat：** |
||||
|
|
||||
|
```bash |
||||
|
TOMCAT_HOME="$HOME/apache-tomcat-9.0.98" |
||||
|
|
||||
|
cp target/student-management.war "$TOMCAT_HOME/webapps/" |
||||
|
"$TOMCAT_HOME/bin/startup.sh" |
||||
|
``` |
||||
|
|
||||
|
### Mac 访问地址 |
||||
|
|
||||
|
``` |
||||
|
http://localhost:8080/student-management/ |
||||
|
``` |
||||
|
|
||||
|
Homebrew 版 Tomcat 9 默认端口为 **8080**。若端口冲突，编辑： |
||||
|
|
||||
|
```bash |
||||
|
# M1 |
||||
|
/opt/homebrew/opt/tomcat@9/libexec/conf/server.xml |
||||
|
|
||||
|
# 修改 <Connector port="8080" ...> 为其他端口 |
||||
|
``` |
||||
|
|
||||
|
### Mac 常用命令对照 |
||||
|
|
||||
|
| 操作 | Windows | Mac M1 | |
||||
|
|------|---------|--------| |
||||
|
| 环境变量文件 | 系统设置 / cmd `set` | `~/.zshrc` | |
||||
|
| 启动 Tomcat | `startup.bat` | `startup.sh` 或 `brew services start tomcat@9` | |
||||
|
| 停止 Tomcat | `shutdown.bat` | `shutdown.sh` 或 `brew services stop tomcat@9` | |
||||
|
| 复制 WAR | `Copy-Item` / 资源管理器 | `cp` | |
||||
|
| Maven 配置 | `C:\Users\用户名\.m2\settings.xml` | `~/.m2/settings.xml` | |
||||
|
|
||||
|
--- |
||||
|
|
||||
|
## 常见错误与解决方案 |
||||
|
|
||||
|
### 错误 1：Maven 代理连接失败 |
||||
|
|
||||
|
**报错信息：** |
||||
|
|
||||
|
``` |
||||
|
Connect to 127.0.0.1:7890 failed: Connection refused: no further information |
||||
|
Could not transfer artifact ... from/to central (https://repo.maven.apache.org/maven2) |
||||
|
``` |
||||
|
|
||||
|
**原因：** |
||||
|
|
||||
|
`~/.m2/settings.xml`（Windows：`C:\Users\用户名\.m2\settings.xml`）中配置了 HTTP 代理 `127.0.0.1:7890`（Clash、V2Ray 等），但代理软件未启动。 |
||||
|

### 错误 2：依赖下载失败被缓存，无法重试 |
||||
|
|
||||
|
**报错信息：** |
||||
|
|
||||
|
``` |
||||
|
failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. |
||||
|
This failure was cached in the local repository and resolution is not reattempted |
||||
|
until the update interval of central has elapsed or updates are forced. |
||||
|
|
||||
|
未解析的依赖项: 'javax.servlet:javax.servlet-api:jar:4.0.1' |
||||
|
未解析的依赖项: 'mysql:mysql-connector-java:jar:8.0.33' |
||||
|
... |
||||
|
``` |
||||
|
|
||||
|
**原因：** |
||||
|
|
||||
|
错误 1 导致的下载失败被 Maven 写入本地仓库缓存（`.lastUpdated` 文件），后续不会自动重试。 |
||||
|
|
||||
|
**解决方案：** |
||||
|
|
||||
|
**步骤 1 — 清理失败缓存** |
||||
|
|
||||
|
Windows PowerShell： |
||||
|
|
||||
|
```powershell |
||||
|
$paths = @( |
||||
|
"$env:USERPROFILE\.m2\repository\javax\servlet\javax.servlet-api\4.0.1", |
||||
|
"$env:USERPROFILE\.m2\repository\javax\servlet\jsp\javax.servlet.jsp-api\2.3.3", |
||||
|
"$env:USERPROFILE\.m2\repository\javax\servlet\jstl\1.2", |
||||
|
"$env:USERPROFILE\.m2\repository\mysql\mysql-connector-java\8.0.33", |
||||
|
"$env:USERPROFILE\.m2\repository\commons-fileupload\commons-fileupload\1.5", |
||||
|
"$env:USERPROFILE\.m2\repository\commons-io\commons-io\2.11.0" |
||||
|
) |
||||
|
foreach ($p in $paths) { if (Test-Path $p) { Remove-Item $p -Recurse -Force } } |
||||
|
Get-ChildItem "$env:USERPROFILE\.m2\repository" -Recurse -Filter "*.lastUpdated" | Remove-Item -Force |
||||
|
``` |
||||
|
|
||||
|
Mac / Linux： |
||||
|
|
||||
|
```bash |
||||
|
rm -rf ~/.m2/repository/javax/servlet/javax.servlet-api/4.0.1 |
||||
|
rm -rf ~/.m2/repository/javax/servlet/jsp/javax.servlet.jsp-api/2.3.3 |
||||
|
rm -rf ~/.m2/repository/javax/servlet/jstl/1.2 |
||||
|
rm -rf ~/.m2/repository/mysql/mysql-connector-java/8.0.33 |
||||
|
rm -rf ~/.m2/repository/commons-fileupload/commons-fileupload/1.5 |
||||
|
rm -rf ~/.m2/repository/commons-io/commons-io/2.11.0 |
||||
|
find ~/.m2/repository -name "*.lastUpdated" -delete |
||||
|
``` |
||||
|
|
||||
|
**步骤 2 — 强制重新下载** |
||||
|
|
||||
|
```bash |
||||
|
mvn -U clean compile |
||||
|
``` |
||||
|
|
||||
|
`-U` 表示强制更新，忽略失败缓存。 |
||||
|
|
||||
|
**步骤 3 — IDEA 刷新** |
||||
|
|
||||
|
右侧 Maven 面板 → 点击 **Reload All Maven Projects**（刷新按钮）。 |
||||

### 错误 3：Tomcat 启动报 JAVA_HOME 未定义 |
||||
|
|
||||
|
**报错信息：** |
||||
|
|
||||
|
``` |
||||
|
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined |
||||
|
At least one of these environment variable is needed to run this program |
||||
|
``` |
||||
|
|
||||
|
**原因：** |
||||
|
|
||||
|
系统未配置 `JAVA_HOME`，Tomcat 找不到 Java。 |
||||
|
|
||||
|
**解决方案：** |
||||
|
|
||||
|
**Windows — 永久配置：** |
||||
|
|
||||
|
1. `Win + R` → `sysdm.cpl` → **高级** → **环境变量** |
||||
|
2. 新建系统变量 `JAVA_HOME` = JDK 安装目录（如 `C:\Program Files\Java\jdk-21`） |
||||
|
3. `Path` 中添加 `%JAVA_HOME%\bin` |
||||
|
4. **重新打开** cmd，执行 `startup.bat` |
||||
|
|
||||
|
**Windows — 临时配置：** |
||||
|
|
||||
|
```cmd |
||||
|
set JAVA_HOME=C:\Program Files\Java\jdk-21 |
||||
|
set JRE_HOME=C:\Program Files\Java\jdk-21 |
||||
|
cd /d D:\apache-tomcat-9.0.98\bin |
||||
|
startup.bat |
||||
|
``` |
||||
|
|
||||
|
**Mac M1 — 永久配置：** |
||||
|
|
||||
|
```bash |
||||
|
# 查看 JDK 路径 |
||||
|
/usr/libexec/java_home -V |
||||
|
|
||||
|
# 写入 ~/.zshrc（以 OpenJDK 17 为例） |
||||
|
echo 'export JAVA_HOME="/opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk/Contents/Home"' >> ~/.zshrc |
||||
|
echo 'export PATH="$JAVA_HOME/bin:$PATH"' >> ~/.zshrc |
||||
|
source ~/.zshrc |
||||
|
|
||||
|
# 验证 |
||||
|
echo $JAVA_HOME |
||||
|
java -version |
||||
|
``` |
||||
|
|
||||
|
**Mac — 临时配置：** |
||||
|
|
||||
|
```bash |
||||
|
export JAVA_HOME=$(/usr/libexec/java_home) |
||||
|
export JRE_HOME=$JAVA_HOME |
||||
|
~/apache-tomcat-9.0.98/bin/startup.sh |
||||
|
``` |
||||
|
|
||||
|
--- |
||||
|
|
||||
|
### 错误 4：页面 404 Not Found |
||||
|
|
||||
|
**原因：** |
||||
|
|
||||
|
- WAR 未放入 `webapps`，或 Tomcat 未完成解压 |
||||
|
- 访问 URL 缺少项目上下文路径 |
||||
|
|
||||
|
**解决方案：** |
||||
|
|
||||
|
1. 确认 `webapps` 下存在 `student-management.war` 或 `student-management/` 文件夹 |
||||
|
2. 访问：`http://localhost:8080/student-management/`（注意含项目名） |
||||
|
3. 查看 Tomcat 日志确认部署是否成功 |
||||
|
|
||||
|
--- |
||||
|
|
||||
|
### 错误 5：页面 500 / 数据库连接失败 |
||||
|
|
||||
|
**原因：** |
||||
|
|
||||
|
- MySQL 未启动 |
||||
|
- `db.properties` 账号密码错误 |
||||
|
- 未执行 `db_init.sql` 初始化数据库 |
||||
|
|
||||
|
**解决方案：** |
||||
|
|
||||
|
```bash |
||||
|
# 检查 MySQL 是否运行 |
||||
|
# Windows |
||||
|
sc query mysql |
||||
|
|
||||
|
# Mac |
||||
|
brew services list | grep mysql |
||||
|
|
||||
|
# 测试连接 |
||||
|
mysql -u root -p -e "USE student_db; SHOW TABLES;" |
||||
|
``` |
||||
|
|
||||
|
确认 `db.properties` 配置正确后，**重新打包并部署** WAR。 |
||||
|
|
||||
|

||||
|
|
||||
|
### 错误 6：8080 端口被占用 |
||||
|
|
||||
|
**报错信息（Tomcat 日志）：** |
||||
|
|
||||
|
``` |
||||
|
Address already in use: bind |
||||
|
``` |
||||
|
|
||||
|
**解决方案：** |
||||
|
|
||||
|
**Windows：** |
||||
|
|
||||
|
```cmd |
||||
|
netstat -ano | findstr :8080 |
||||
|
taskkill /PID <进程号> /F |
||||
|
``` |
||||
|
|
||||
|
**Mac：** |
||||
|
|
||||
|
```bash |
||||
|
lsof -i :8080 |
||||
|
kill -9 <PID> |
||||
|
``` |
||||
|
|
||||
|
或修改 Tomcat `conf/server.xml` 中 `<Connector port="8080">` 为其他端口（如 8081）。 |
||||
|
|
||||
|

||||
|
|
||||
|
## Maven 推荐配置 |
||||
|
|
||||
|
将以下内容写入 Maven 用户配置文件： |
||||
|
|
||||
|
- **Windows：** `C:\Users\你的用户名\.m2\settings.xml` |
||||
|
- **Mac：** `~/.m2/settings.xml` |
||||
|
|
||||
|
```xml |
||||
|
<settings> |
||||
|
<mirrors> |
||||
|
<mirror> |
||||
|
<id>aliyunmaven</id> |
||||
|
<mirrorOf>central</mirrorOf> |
||||
|
<name>Aliyun Maven</name> |
||||
|
<url>https://maven.aliyun.com/repository/public</url> |
||||
|
</mirror> |
||||
|
</mirrors> |
||||
|
|
||||
|
<!-- 代理软件（Clash 等）未启动时请将 active 设为 false --> |
||||
|
<proxies> |
||||
|
<proxy> |
||||
|
<id>http-proxy</id> |
||||
|
<active>false</active> |
||||
|
<protocol>http</protocol> |
||||
|
<host>127.0.0.1</host> |
||||
|
<port>7890</port> |
||||
|
</proxy> |
||||
|
<proxy> |
||||
|
<id>https-proxy</id> |
||||
|
<active>false</active> |
||||
|
<protocol>https</protocol> |
||||
|
<host>127.0.0.1</host> |
||||
|
<port>7890</port> |
||||
|
</proxy> |
||||
|
</proxies> |
||||
|
</settings> |
||||
|
``` |
||||
|
|
||||
|
**IDEA 中确认 Maven 使用该配置：** |
||||
|
|
||||
|
`File → Settings → Build Tools → Maven → User settings file` 指向上述 `settings.xml`。 |
||||
|
|
||||
|
