springboot2.7整合knife4j4.3

springboot2.7整合knife4j4.3是指在Springboot 2.7版本中使用Knife4j 4.3进行API文档的生成和管理。具体步骤如下：
1.在pom.xml文件中添加Knife4j的依赖：

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>4.3.0</version>
</dependency>

2.在application.yml文件中进行配置：

spring:
  profiles:
    active: dev
  application:
    name: demo-knife4j-openapi3
  servlet:
    multipart:
      max-file-size: 10MB
      max-request-size: 100MB
  resources:
    static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8
    serialization:
      fail-on-empty-beans: false
      indent-output: true
      write-dates-as-timestamps: false
      write-null-map-values: false
      write-empty-json-arrays: false
      write-enums-using-to-string: true
  http:
    encoding:
      charset: UTF-8
      enabled: true
  servlet:
    session:
      timeout: 30m
  datasource:
    url: jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      initial-size: 5
      min-idle: 5
      max-active: 20
      test-on-borrow: true
      validation-query: SELECT 1 FROM DUAL
      filters: stat,wall,log4j
      connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
      naming:
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
server:
  port: 8080
  tomcat:
    uri-encoding: UTF-8
    max-threads: 200
    min-spare-threads: 10
    max-http-header-size: 1048576
    accesslog:
      enabled: true
      directory: logs
      prefix: access_log
      suffix: .log
      rotate: true
      pattern: common

3.在启动类上添加@EnableKnife4j注解：

@SpringBootApplication
@EnableKnife4j
public class DemoKnife4jOpenapi3Application {

    public static void main(String[] args) {
        SpringApplication.run(DemoKnife4jOpenapi3Application.class, args);
    }

}
