swagger-api生成接口文档

引入swagger-api 生成接口文档

1.引入pom依赖

  <!-- swagger2依赖-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- swagger-ui界面依赖 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
        </dependency>

2.增加配置类（用于指定生成API的扫描路径等）

package com.zg.common.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
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
@EnableWebMvc
public class Swagger2Config implements WebMvcConfigurer {

    @Bean
    public Docket createDocketForSwaggerAPI() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()
                .apis(RequestHandlerSelectors.basePackage("com.zg.common.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    @Bean
    public ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("zg的swagger测试接口文档")
                .description("测试")
                .termsOfServiceUrl("")
                .version("1.0")
                .build();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
        registry.addResourceHandler("/swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
        WebMvcConfigurer.super.addResourceHandlers(registry);
    }
}

@EnableWebMvc注解用于解决springboot2.6版本以后和swagger路径映射不匹配的问题
重写addResourceHandlers方法用于将swagger-ui的静态资源注册进dispatchservlet,用于解决No mapping for GET /swagger-ui.html问题
