SpringBoot 集成Swagger 不同的姿势

通用配置

SpringBoot依赖

代码语言：javascript复制

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.10</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Yml配置

代码语言：javascript复制

spring:
	mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

Springboot2.6以后将SpringMVC 默认路径匹配策略从AntPathMatcher 更改为PathPatternParser，所以不加该配置会报错：org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

依赖版本的差异性

3.0.x 以下

依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>

/**

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(true)
                .pathMapping("/")
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.xts.fm.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("springboot利用swagger构建api文档")
                .description("简单优雅的Restful风格")
                .termsOfServiceUrl("https://www.syilun.top/")
                .version("1.0")
                .build();
    }
}

注意

如果有过滤器或者拦截器之类的记得放开swagger对应的路径。

效果演示

3.0.x以及之上

依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>

@Configuration
@EnableOpenApi
public class SwaggerConfig3 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(true)

                .version("1.0")
                .build();
    }
}

注意

3.0.x之前的swagger请求URL地址是：localhost:8080/swagger-ui.html#/

3.0.x以及上的swagger请求URL地址为：http://localhost:8080/swagger-ui/index.html#/
