swagger 2.0

1、引入jar包

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

2、配置swagger配置文件

import io.swagger.annotations.Api;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
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;

/**
 * @author xiufengd
 * @date 2021/8/10 10:59
 * @description 用于生成API接口文档的配置
 * @note 未来可期
 */
@Configuration
@EnableSwagger2
//@EnableWebMvc  注掉默认的，改成继承WebMvcConfigurationSupport，重写addResourceHandlers，将swagger-ui.html映射出来
public class SwaggerConfig extends WebMvcConfigurationSupport {

    @Bean
    public Docket petApi() {

        ParameterBuilder ticketPar = new ParameterBuilder();

        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .apis(RequestHandlerSelectors.basePackage("com.dxf.controller")) //指定提供接口所在的基包
                .build();
    }

    /**
     * 该套 API 说明，包含作者、简介、版本、host、服务URL
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口文档")
                .version("0.1")
                .description("该接口文档暂时只用于前后端调试对接使用，切勿对外暴露！")
                .build();
    }
    //将swagger-ui.html 映射到项目中可以直接访问
    @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/");
        super.addResourceHandlers(registry);
    }

}

3、在类上注解写到死

import io.swagger.annotations.*;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import java.util.HashMap;
import java.util.Map;

/**
 * @author xiufengd
 * @date 2021/8/6 17:59
 * @description
 * @note 未来可期
 */
@Api(value = "测试接口类",tags ="测试接口类")
@Controller("test")
@RequestMapping("test")
public class test {

    @ApiOperation(value = "定义测试接口方法")
    @GetMapping("test")
    //定义返回
    @ApiResponses({
            @ApiResponse(code = 200, message = "{\"status\":200,\"msg\":\"ok\",\"data\":\"success data\"}"),
            @ApiResponse(code = 201, message = "{\"status\":201,\"msg\":\"ok\",\"data\":\"error data\"}")
    })
    @ResponseBody
    public Object test(@RequestParam @ApiParam("参数名") String param) throws Exception {
        Map<String,String> result = new HashMap<>();
        result.put("code", "200");
        result.put("message", "ok");
        result.put("data", "success data");
        return result;
    }
}

4、shiro放开权限

　　　　<!-- swagger配置 -->
　　　　/swagger-ui.html=anon
　　　　/swagger-resources=anon
　　　　/v2/api-docs=anon
　　　　/webjars/springfox-swagger-ui/**=anon
