学成在线：初始化工程

创建learning-online-checkcode工程，目录结构如下

learning-online-media
├── src/main/java
│   ├── com.swx.checkcode
│   │   ├── config
│   │   ├── controller
│   │   ├── model
│   │   ├── service
│   │   └── CheckCodeApplication.java
│   └──resource
└── pom.xml

在pom文件中添加如下依赖：

pom.xml

<dependencies>
    <dependency>
        <groupId>com.swx</groupId>
        <artifactId>learning-online-base</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>
    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
    </dependency>

    <dependency>
        <groupId>com.github.penggle</groupId>
        <artifactId>kaptcha</artifactId>
        <version>2.3.2</version>
    </dependency>
    <!-- Spring Boot 的 Spring Web MVC 集成 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- 排除 Spring Boot 依赖的日志包冲突 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-pool2</artifactId>
        <version>2.6.2</version>
    </dependency>
    <!-- Spring Boot 集成 log4j2 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>
</dependencies>

创建启动类，在com.swx.checkcode包下创建启动类CheckCodeApplication，内容如下：

CheckCodeApplication

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

项目配置信息，在resources下创建bootstrap.yml

bootstrap.yml

spring:
  application:
    name: checkcode
  cloud:
    nacos:
      discovery:
        server-addr: 124.221.23.47:8848
        namespace: learning-online-dev
        group: learning-online-project
      config:
        server-addr: 124.221.23.47:8848
        namespace: learning-online-dev
        group: learning-online-project
        file-extension: yaml
        refresh-enabled: true
        shared-configs:
          - data-id: logging-${spring.profiles.active}.yaml
            group: learning-online-common
            refresh: true
          - data-id: redis-${spring.profiles.active}.yaml
            group: learning-online-common
            refresh: true
  profiles:
    active: dev

日志配置，在resources下创建log4j2-dev.xml

log4j2-dev.xml
