1、单体项目集成

•  添加依赖：

  
     mysql
     mysql-connector-java
     8.0.29
  
  
     com.baomidou
     mybatis-plus-boot-starter
     3.5.3.1
  
  
     com.github.xiaoymin
     knife4j-spring-boot-starter
     3.0.3
  

• 编写配置类：

  /**
   * @CreateTime: 2023-10-14  15:33
   * @Description: 接口文档配置
   * @Version: 1.0
   */
  @Configuration
  @EnableSwagger2
  public class Knife4jConfiguration {
      @Bean
      public Docket createRestApi() {
          return new Docket(DocumentationType.SWAGGER_2)
                  .useDefaultResponseMessages(false)
                  .apiInfo(apiInfo())
                  .select().apis(RequestHandlerSelectors.basePackage("org.coding.controller"))
                  .paths(PathSelectors.any()).build();
      }
      private ApiInfo apiInfo() {
          return new ApiInfoBuilder()
                  .description("Knife4j API接口文档")
                  .contact(new Contact("demo", "https://xxx.xxx.xxx/demo", "XXX@qq.com"))
                  .version("v1.0")
                  .title("Spring Boot 集成 Validation 参数校验API测试文档").build();
      }
  }
  

• 配置静态资源：

  package org.coding.config.knife4j;
  import org.springframework.context.annotation.Configuration;
  import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
  import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
  /**
   * @CreateTime: 2023-10-15  17:16
   * @Version: 1.0
   */
  @Configuration
  public class PersonWebMvcConfiguration extends WebMvcConfigurationSupport {
          @Override
          public void addResourceHandlers(ResourceHandlerRegistry registry) {
              registry.addResourceHandler("/**", "classpath:/static/");
              registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
              registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
              super.addResourceHandlers(registry);
          }
  }

• 2、boot3.0集成knife4j4.3.0

  • 依赖

    
       com.github.xiaoymin
       knife4j-openapi3-jakarta-spring-boot-starter
       4.3.0
    

    • 配置

    • @Configuration
      public class Knife4jConfig {
          @Bean
          public OpenAPI springShopOpenAPI() {
              return new OpenAPI()
                      .info(new Info().title("API接口文档")
                              .description("boot3整合mybatis-plus")
                              .version("v1.0")
                              .license(new License().name("Apache 2.0").url("http://springdoc.org")))
                              .externalDocs(new ExternalDocumentation()
                              .description("外部文档")
                              .url("https://springshop.wiki.github.org/docs"));
          }
      }

    • 属性配置【https://doc.xiaominfo.com/docs/quick-start#spring-boot-3】

      # springdoc-openapi项目配置
      springdoc:
        swagger-ui:
          path: /swagger-ui.html
          tags-sorter: alpha
          operations-sorter: alpha
        api-docs:
          path: /v3/api-docs
        group-configs:
          - group: 'user'
            paths-to-match: '/**'
            packages-to-scan: org.coding.java.controller
      # knife4j的增强配置，不需要增强可以不配
      knife4j:
        enable: true
        setting:
          language: zh_cn
