spring boot 2整合swagger-ui过程解析

2021-04-02 我要评论

这篇文章主要介绍了spring boot 2整合swagger-ui过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

1.添加mvn依赖

修改pom.xml加入

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>2.5.0</version>
</dependency>
<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger-ui</artifactId>
  <version>2.5.0</version>
</dependency>

2.创建配置类

在Application.java同级创建Swagger2的配置类Swagger2

package com.tydt.decision;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2{
  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.tydt.decision.controller"))
        .paths(PathSelectors.any()).build();
  }

  private ApiInfo apiInfo() {
    return new ApiInfoBuilder().title("Decision Manage Swagger RESTful APIs")
        .description("Decision API")
        .termsOfServiceUrl("http://swagger.io/")
        .contact(new Contact("Beibei", "127.0.0.1", "XXXXXXX@qq.com"))
        .version("1.0")
        .build();

  }

}

注：

如果出现下面情况

引入需要的包

但是启动时又出现Error creating bean with name 'apiDocumentationScanner' defined in URL

这是由于swagger依赖google的guava，需要添加依赖，而当前项目的guava版本与之不匹配，修改为

<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>15.0</version>
</dependency>

http://localhost:8090/swagger-ui.html页面没显示

这是因为Spring Boot自动配置本身不会自动把/swagger-ui.html这个路径映射到对应的目录META-INF/resources/下面。加上这个映射即可

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
  
  ……
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
        .addResourceLocations("classpath:/META-INF/resources/");
    registry.addResourceHandler("/webjars/**")
        .addResourceLocations("classpath:/META-INF/resources/webjars/");

  }
}

解决了上面出现的问题，访问http://localhost:8090/swagger-ui.html就能看到下面的页面了
