Springboot整合Swagger-ui实现在线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

一、导入依赖

        
        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger2artifactId>
            <version>2.7.0version>
        dependency>
        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger-uiartifactId>
            <version>2.7.0version>
        dependency>

二、编写swagger-ui的配置文件

@EnableSwagger2
@Configuration
public class Swagger2Config {

    @Autowired
    private FireworksConfig fireworksConfig;

    /**
     * 创建API
     *
     * @return
     */
    @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.smday.fireworks"))
                //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()
                .securitySchemes(securitySchemes())
                .securityContexts(securityContexts());
    }

    /**
     * 设置安全上下文
     *
     * @return
     */
    private List<SecurityContext> securityContexts() {
        //设置需要登录认证的路径
        List<SecurityContext> result = new ArrayList<>();
        result.add(getContextByPath("/admin/.*"));

        return result;
    }

    /**
     * 需要认证的路径
     *
     * @param pathRegex
     * @return
     */
    private SecurityContext getContextByPath(String pathRegex) {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.regex(pathRegex))
                .build();
    }

    /**
     * 默认的安全引用
     *
     * @return
     */
    private List<SecurityReference> defaultAuth() {
        List<SecurityReference> result = new ArrayList<>();
        AuthorizationScope authorizationScope = new AuthorizationScope("global", "accessEverything");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        result.add(new SecurityReference("Authorization", authorizationScopes));
        return result;
    }

    /**
     * 安全模式,这里指定token通过Authrization请求头传递
     *
     * @return
     */
    private List<? extends SecurityScheme> securitySchemes() {
        //设置请求头信息
        List<ApiKey> result = new ArrayList<>();
        ApiKey apiKey = new ApiKey("Authorization", "Authorization", "header");
        result.add(apiKey);
        return result;
    }

    /**
     * 添加摘要信息
     *
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("标题:Fireworks个人网站系统接口文档")
                .description("fireworks个人网站:用户模块,后台管理模块,收藏模块,日志模块,安全模块")
                .contact(new Contact(fireworksConfig.getName(), "https://www.hyhwky.com", "[email protected]"))
                .version("版本号: " + fireworksConfig.getVersion())
                .build();
    }
}

三、添加注解

@RestController
@RequestMapping("/user")
@Api(tags = "UserController", description = "用户管理")
public class SysUserController {
    @PostMapping("/login")
    @ApiOperation("登录功能")
    public AjaxResult login(@RequestBody UserLoginParam userLoginParam){

        AjaxResult ajaxResult = AjaxResult.success();
        String token = sysLoginService.login(userLoginParam.getUsername(), userLoginParam.getPassword());
        ajaxResult.put("token",token);
        return ajaxResult;
    }
}

@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserLoginParam {
    
    @ApiModelProperty(value = "用户名", required = true)
    @NotEmpty(message = "用户名不能为空")
    private String username;

    @ApiModelProperty(value = "密码", required = true)
    @NotEmpty(message = "密码不能为空")
    private String password;

    @ApiModelProperty(value = "随机码",required = true)
    private String validateCode;

}

四、启动项目，并测试接口，访问url：http://localhost:8083/swagger-ui.html
