前言
之前在SpringBoot项目中一直使用的是SpringFox提供的Swagger库,上了下官网发现已经有接近两年没出新版本了!前几天升级了SpringBoot 2.6.x 版本,发现这个库的兼容性也越来越不好了,有的常用注解属性被废弃了居然都没提供替代!无意中发现了另一款Swagger库SpringDoc,试用了一下非常不错,推荐给大家!

SpringDoc简介
SpringDoc是一款可以结合SpringBoot使用的API文档生成工具,基于OpenAPI 3,目前在Github上已有1.7K+Star,更新发版还是挺勤快的,是一款更好用的Swagger库!值得一提的是SpringDoc不仅支持Spring WebMvc项目,还可以支持Spring WebFlux项目,甚至Spring Rest和Spring Native项目,总之非常强大,下面是一张SpringDoc的架构图。
使用
接下来我们介绍下SpringDoc的使用,使用的是之前集成SpringFox的mall-tiny-swagger项目,我将把它改造成使用SpringDoc。
集成
首先我们得集成SpringDoc,在pom.xml中添加它的依赖即可,开箱即用,无需任何配置。
<!--springdoc 官方Starter-->
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.6</version>
</dependency>
从SpringFox迁移
- 我们先来看下经常使用的Swagger注解,看看SpringFox的和SpringDoc的有啥区别,毕竟对比已学过的技术能该快掌握新技术;
SpringFox | SpringDoc |
---|---|
@Api | @Tag |
@ApiIgnore | @Parameter(hidden = true)or@Operation(hidden = true)or@Hidden |
@ApiImplicitParam | @Parameter |
@ApiImplicitParams | @Parameters |
@ApiModel | @Schema |
@ApiModelProperty | @Schema |
@ApiOperation(value = "foo", notes = "bar") | @Operation(summary = "foo", description = "bar") |
@ApiParam | @Parameter |
@ApiResponse(code = 404, message = "foo") | ApiResponse(responseCode = "404", description = "foo") |
接下来我们对之前Controller中使用的注解进行改造,对照上表即可,之前在@Api注解中被废弃了好久又没有替代的description属性终于被支持了!
@Tag(name = "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);
@Operation(summary = "获取所有品牌列表",description = "需要登录后访问")
@RequestMapping(value = "listAll", method = RequestMethod.GET)
@ResponseBody
public CommonResult<List<PmsBrand>> getBrandList() {
return CommonResult.success(brandService.listAllBrand());
}
@Operation(summary = "添加品牌")
@RequestMapping(value = "/create", method = RequestMethod.POST)
@ResponseBody
@PreAuthorize("hasRole('ADMIN')")
public CommonResult createBrand(@RequestBody PmsBrand pmsBrand) {
CommonResult commonResult;
int count = brandService.createBrand(pmsBrand);
if (count == 1) {
commonResult = CommonResult.success(pmsBrand);
LOGGER.debug("createBrand success:{}", pmsBrand);
} else {
commonResult = CommonResult.failed("操作失败");
LOGGER.debug("createBrand failed:{}", pmsBrand);
}
return commonResult;
}
@Operation(summary = "更新指定id品牌信息")
@RequestMapping(value = "/update/{id}", method = RequestMethod.POST)
@ResponseBody
@PreAuthorize("hasRole('ADMIN')")
public CommonResult updateBrand(@PathVariable("id") Long id, @RequestBody PmsBrand pmsBrandDto, BindingResult result) {
CommonResult commonResult;
int count = brandService.updateBrand(id, pmsBrandDto);
if (count == 1) {
commonResult = CommonResult.success(pmsBrandDto);
LOGGER.debug("updateBrand success:{}", pmsBrandDto);
} else {
commonResult = CommonResult.failed("操作失败");
LOGGER.debug("updateBrand failed:{}", pmsBrandDto);
}
return commonResult;
}
@Operation(summary = "删除指定id的品牌")
@RequestMapping(value = "/delete/{id}", method = RequestMethod.GET)
@ResponseBody
@PreAuthorize("hasRole('ADMIN')")
public CommonResult deleteBrand(@PathVariable("id") Long id) {
int count = brandService.deleteBrand(id);
if (count == 1) {
LOGGER.debug("deleteBrand success :id={}", id);
return CommonResult.success(null);
} else {
LOGGER.debug("deleteBrand failed :id={}", id);
return CommonResult.failed("操作失败");
}
}
@Operation(summary = "分页查询品牌列表")
@RequestMapping(value = "/list", method = RequestMethod.GET)
@ResponseBody
@PreAuthorize("hasRole('ADMIN')")
public CommonResult<CommonPage<PmsBrand>> listBrand(@RequestParam(value = "pageNum", defaultValue = "1")
@Parameter(description = "页码") Integer pageNum,
@RequestParam(value = "pageSize", defaultValue = "3")
@Parameter(description = "每页数量") Integer pageSize) {
List<PmsBrand> brandList = brandService.listBrand(pageNum, pageSize);
return CommonResult.success(CommonPage.restPage(brandList));
}
@Operation(summary = "获取指定id的品牌详情")
@RequestMapping(value = "/{id}", method = RequestMethod.GET)
@ResponseBody
@PreAuthorize("hasRole('ADMIN')")
public CommonResult<PmsBrand> brand(@PathVariable("id") Long id) {
return CommonResult.success(brandService.getBrand(id));
}
}
接下来进行SpringDoc的配置,使用OpenAPI来配置基础的文档信息,通过GroupedOpenApi配置分组的API文档,SpringDoc支持直接使用接口路径进行配置。
@Configuration
public class SpringDocConfig {
@Bean
public OpenAPI mallTinyOpenAPI() {
return new OpenAPI()
.info(new Info().title("Mall-Tiny API")
.description("SpringDoc API 演示")
.version("v1.0.0")
.license(new License().name("Apache 2.0").url("https://github.com/macrozheng/mall-learning")))
.externalDocs(new ExternalDocumentation()
.description("SpringBoot实战电商项目mall(50K+Star)全套文档")
.url("http://www.macrozheng.com"));
}
@Bean
public GroupedOpenApi publicApi() {
return GroupedOpenApi.builder()
.group("brand")
.pathsToMatch("/brand
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.csrf()// 由于使用的是JWT,我们这里不需要csrf
.disable()
.sessionManagement()// 基于token,所以不需要session
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers(HttpMethod.GET, // Swagger的资源路径需要允许访问
"/",
"/swagger-ui.html",
"/swagger-ui/",
"*.html",
"*.css",
"*.js",
"/swagger-resources
@Configuration
public class SpringDocConfig {
private static final String SECURITY_SCHEME_NAME = "BearerAuth";
@Bean
public OpenAPI mallTinyOpenAPI() {
return new OpenAPI()
.info(new Info().title("Mall-Tiny API")
.description("SpringDoc API 演示")
.version("v1.0.0")
.license(new License().name("Apache 2.0").url("https://github.com/macrozheng/mall-learning")))
.externalDocs(new ExternalDocumentation()
.description("SpringBoot实战电商项目mall(50K+Star)全套文档")
.url("http://www.macrozheng.com"))
.addSecurityItem(new SecurityRequirement().addList(SECURITY_SCHEME_NAME))
.components(new Components()
.addSecuritySchemes(SECURITY_SCHEME_NAME,
new SecurityScheme()
.name(SECURITY_SCHEME_NAME)
.type(SecurityScheme.Type.HTTP)
.scheme("bearer")
.bearerFormat("JWT")));
}
}
测试
接下来启动项目就可以访问Swagger界面了,访问地址:http://localhost:8088/swagger-ui.html
我们先通过登录接口进行登录,可以发现这个版本的Swagger返回结果是支持高亮显示的,版本明显比SpringFox来的新;
然后通过认证按钮输入获取到的认证头信息,注意这里不用加bearer前缀;
之后我们就可以愉快地访问需要登录认证的接口了;
看一眼请求参数的文档说明,还是熟悉的Swagger样式!
常用配置
SpringDoc还有一些常用的配置可以了解下,更多配置可以参考官方文档。
springdoc:
swagger-ui:
# 修改Swagger UI路径
path: /swagger-ui.html
# 开启Swagger UI界面
enabled: true
api-docs:
# 修改api-docs路径
path: /v3/api-docs
# 开启api-docs
enabled: true
# 配置需要生成接口文档的扫描包
packages-to-scan: com.macro.mall.tiny.controller
# 配置需要生成接口文档的接口路径
paths-to-match: /brand/**,/admin/**
总结
在SpringFox的Swagger库好久不出新版的情况下,迁移到SpringDoc确实是一个更好的选择。今天体验了一把SpringDoc,确实很好用,和之前熟悉的用法差不多,学习成本极低。而且SpringDoc能支持WebFlux之类的项目,功能也更加强大,使用SpringFox有点卡手的朋友可以迁移到它试试!
