springboot 配置 swagger2

1.pom.xml 添加依赖

        <!--swagger2 依赖-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${swagger.version}</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>${swagger.version}</version>
        </dependency>

2.配置一个配置类

package cn.cenxi.express.config;

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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
//@EnableSwagger2  [如果在这里配置的话,则不需要在启动类配置了]
public class Swagger2Config {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any()).build();
    }

    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("校园快递代拿api")
                .description("校园快递代拿后端应用接口")
                .version("1.0")
                .build();
    }

}

3.在启动类开启

@EnableSwagger2

4.测试

启动工程后 ，

使用本地工程地址和端口 加 /swagger-ui.html

如我的 http://localhost:57/swagger-ui.html

 5.注解使用如下
