spring boot 添加swagger支持

添加maven依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>


<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>3.0.0</version>
</dependency>

 

添加java 类

@Configuration
public class SpringFoxConfig {                                    
    @Bean
    public Docket api() { 
        return new Docket(DocumentationType.SWAGGER_2)  
          .select()                                  
          .apis(RequestHandlerSelectors.any())              
          .paths(PathSelectors.any())                          
          .build();                                           
    }
}

访问地址
ip:port/${context-path}/swagger-ui/

 

如果报这个
org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException
添加如下spring 配置

spring:
    mvc:
      pathmatch:
            matching-strategy: ant_path_matcher
