Springdoc替换swagger的实现步骤分解

码农-文若书生 2023-03-21 我要评论

前言

距离swagger上次发布版本已经过去两年多了，一直没有更新，与当前的springboot2.6.x、springboot2.7.x存在各种兼容问题，对于即将发布的springboot3.x，可能存在更多兼容问题。如下图所示。

其实swagger还在更新，应该是springfox不更新导致的，所以需要使用其他的API管理工具代替,springdoc是一种选择

一、springdoc介绍

SpringDoc是一款可以结合SpringBoot使用的API文档生成工具，基于OpenAPI 3，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。

二、使用步骤

1.引入库

gradle：

api group: 'org.springdoc', name: 'springdoc-openapi-ui', version: '1.6.11'

maven:

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>1.6.11</version>
</dependency>

2.spring配置类

创建一个spring配置类，添加springdoc的配置

@AutoConfiguration
public class SpringDocConfig {
    @Bean
    public OpenAPI openAPI() {
        return new OpenAPI()
                .info(new Info()
                        .title("newframe-接口文档")
                        .description("基于SpringDoc的在线接口文档")
                        .version("0.0.1"));
    }
    @Bean
    public GroupedOpenApi publicApi() {
        return GroupedOpenApi.builder()
                .group("权限相关")
                .packagesToScan("com.iscas.biz.controller.common.auth")
                .build();
    }
    @Bean
    public GroupedOpenApi adminApi() {
        return GroupedOpenApi.builder()
                .group("默认")
                .pathsToMatch("/**")
                .build();
    }
}

3.常用的swagger注解和springdoc的对应关系

4.一个接口类的示例

@Tag(name = "组织机构管理-OrgController")
@RestController
@RequestMapping("/org")
@Validated
@ConditionalOnMybatis
public class OrgController extends BaseController {
    private final OrgService orgService;

    public OrgController(OrgService orgService) {
        this.orgService = orgService;
    }
    @Operation(summary="[组织机构]获取组织机构树", description="create by:朱全文 2021-02-20")
    @GetMapping
    public TreeResponse get() throws BaseException {
        return getTreeResponse().setValue(orgService.getTree());
    }
    @Operation(summary="[组织机构]新增组织机构节点", description="create by:朱全文 2021-02-20")
    @io.swagger.v3.oas.annotations.parameters.RequestBody(required = true, description = "组织机构数据",
            content = @Content(schema = @Schema(implementation = Org.class)))
    @PostMapping("/node")
    public ResponseEntity addNode(@Valid @RequestBody Org org) throws BaseException {
        return getResponse().setValue(orgService.addOrg(org));
    }
    @Operation(summary="[组织机构]修改组织机构节点", description="create by:朱全文 2021-02-20")
    @io.swagger.v3.oas.annotations.parameters.RequestBody(required = true, description = "组织机构数据",
            content = @Content(schema = @Schema(implementation = Org.class)))
    @PutMapping("/node")
    public ResponseEntity editNode(@Valid @RequestBody Org org) {
        return getResponse().setValue(orgService.editOrg(org));
    }
    @Operation(summary="[组织机构]删除组织机构节点", description="create by:朱全文 2021-02-20")
    @io.swagger.v3.oas.annotations.parameters.RequestBody(required = true, description = "组织机构ID集合", content = @Content(examples = @ExampleObject(value = "[123, 124]")))
    @PostMapping("/node/del")
    @Caching(evict = {
            @CacheEvict(value = "auth", key = "'url_map'"),
            @CacheEvict(value = "auth", key = "'menus'"),
            @CacheEvict(value = "auth", key = "'role_map'")
    })
    public ResponseEntity deleteNode(@RequestBody List<Integer> orgIds) {
        AssertCollectionUtils.assertCollectionNotEmpty(orgIds, "orgIds不能未空");
        orgService.deleteNode(orgIds);
        return getResponse();
    }
}

5.配置文件配置

springdoc.swagger-ui.doc-expansion=none
springdoc.swagger-ui.path=/doc.html

还有其他的各种配置，可以在写配置的时候查看提示

6.WebMvc配置

@AutoConfiguration
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.
                addResourceHandler("/swagger-ui/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/springfox-swagger-ui/")
                .resourceChain(false);
        registry.
                addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/swagger-ui/")
                .setViewName("forward:/swagger-ui/index.html");
    }
}

7.UI

访问地址：http://localhost:7901/demo/swagger-ui/ 或 http://localhost:7901/demo/doc.html
UI还使用swagger的UI，如下图所示：
