快速入门

单体 Web 应用

场景1:单体 Web 应用快速开始。

场景1:单体 Web 应用

适合:中小型项目、快速原型、学习使用

步骤1:创建项目

使用 Maven 创建项目:

mvn archetype:generate \
    -DgroupId=com.example \
    -DartifactId=demo-web \
    -DarchetypeArtifactId=maven-archetype-quickstart \
    -DinteractiveMode=false

cd demo-web

步骤2:添加依赖

编辑 pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
         http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>demo-web</artifactId>
    <version>1.0.0</version>
    <packaging>jar</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.5.8</version>
    </parent>

    <properties>
        <java.version>21</java.version>
        <nebula.version>2.0.1-SNAPSHOT</nebula.version>
    </properties>

    <dependencies>
        <!-- Nebula Web Starter -->
        <dependency>
            <groupId>io.nebula</groupId>
            <artifactId>nebula-starter-web</artifactId>
            <version>${nebula.version}</version>
        </dependency>

        <!-- 测试依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

步骤3:创建配置文件

创建 src/main/resources/application.yml

spring:
  application:
    name: demo-web

server:
  port: 8080

nebula:
  # 启用 Web 支持
  web:
    enabled: true

  # 数据访问配置(如需要)
  data:
    persistence:
      enabled: true

  # 缓存配置(如需要)
  cache:
    enabled: true
    type: caffeine

步骤4:创建启动类

创建 src/main/java/com/example/DemoWebApplication.java

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoWebApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoWebApplication.class, args);
    }
}

步骤5:创建第一个接口

创建 src/main/java/com/example/controller/HelloController.java

package com.example.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello(@RequestParam(defaultValue = "World") String name) {
        return "Hello, " + name + "!";
    }
}

步骤6:运行应用

```bash
