SpringBoot2 整合Swagger-UI

Swagger-UI

Swagger-UI是HTML, Javascript, CSS的一个集合，可以动态地根据注解生成在线API文档。

常用注解

• @Api：用于修饰Controller类，生成Controller相关文档信息
• @ApiOperation：用于修饰Controller类中的方法，生成接口方法相关文档信息
• @ApiParam：用于修饰接口中的参数，生成接口参数相关文档信息
• @ApiModelProperty：用于修饰实体类的属性，当实体类是请求参数或返回结果时，直接生成相关文档信息

整合Swagger-UI

在pom.xml中新增Swagger-UI相关依赖

	<!--Swagger-UI API文档生产工具-->
	<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>

添加Swagger-UI的配置

Swagger对生成API文档的范围有三种不同的选择

• 生成指定包下面的类的API文档
• 生成有指定注解的类的API文档
• 生成有指定注解的方法的API文档

注意 :

添加注解 @EnableSwagger2, @Configuration

package com.macro.mall.tiny.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;

/**
 * Swagger2API文档的配置
 */
@Configuration
@EnableSwagger2
public class Swagger2Config {
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包下controller生成API文档
                .apis(RequestHandlerSelectors.basePackage("com.macro.mall.tiny.controller"))
                //为有@Api注解的Controller生成API文档
//                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                //为有@ApiOperation注解的方法生成API文档
//                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("SwaggerUI演示")
                .description("mall-tiny")
                .contact("macro")
                .version("1.0")
                .build();
    }
}

给Controller类添加Swagger注解

package com.macro.mall.tiny.controller;

import com.macro.mall.tiny.common.api.CommonPage;
import com.macro.mall.tiny.common.api.CommonResult;
import com.macro.mall.tiny.mbg.model.PmsBrand;
import com.macro.mall.tiny.service.PmsBrandService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@Api(tags = "PmsBrandController", description = "商品品牌管理")
@Controller
@RequestMapping("/brand")
public class PmsBrandController {
    @Autowired
    private PmsBrandService brandService;

    private static final Logger LOGGER = LoggerFactory.getLogger(PmsBrandController.class);

    @ApiOperation("获取所有品牌列表")
    @RequestMapping(value = "listAll", method = RequestMethod.GET)
    @ResponseBody
    public CommonResult<List<PmsBrand>> getBrandList() {
        ...
    }

    @ApiOperation("添加品牌")
    @RequestMapping(value = "/create", method = RequestMethod.POST)
    @ResponseBody
    public CommonResult createBrand(@RequestBody PmsBrand pmsBrand) {
        ...
    }

    @ApiOperation("更新指定id品牌信息")
    @RequestMapping(value = "/update/{id}", method = RequestMethod.POST)
    @ResponseBody
    public CommonResult updateBrand(@PathVariable("id") Long id, @RequestBody PmsBrand pmsBrandDto, BindingResult result) {
       ...
    }

    @ApiOperation("删除指定id的品牌")
    @RequestMapping(value = "/delete/{id}", method = RequestMethod.GET)
    @ResponseBody
    public CommonResult deleteBrand(@PathVariable("id") Long id) {
       ....
    }
 	@ApiOperation("分页查询品牌列表")
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    @ResponseBody
    public CommonResult<CommonPage<PmsBrand>> listBrand(@RequestParam(value = "pageNum", defaultValue = "1")
                                                        @ApiParam("页码") Integer pageNum,
                                                        @RequestParam(value = "pageSize", defaultValue = "3")
                                                        @ApiParam("每页数量") Integer pageSize) {
        ...
    }
                  
}
