SpringBoot2.6.13版本引入Swagger

1.引入依赖

<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>3.0.0</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.github.xiaoymin/swagger-bootstrap-ui -->
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>swagger-bootstrap-ui</artifactId>
    <version>1.9.6</version>
</dependency>

2.配置类

 1 @Configuration
 2 @EnableSwagger2
 3 public class SwaggerConfig implements WebMvcConfigurer {
 4 
 5     @Value("${springfox.documentation.enabled:false}")
 6     private boolean enabled;
 7 
 8     @Bean
 9     public Docket api() {
10         return new Docket(DocumentationType.SWAGGER_2)
11                 .enable(enabled)
12                 .apiInfo(apiInfo())
13                 .select()
14                  //替换为你的控制器包路径
15                 .apis(RequestHandlerSelectors.basePackage("com.xxx.controller"))
16                 .paths(PathSelectors.any())
17                 .build();
18     }
19 
20 
21     private ApiInfo apiInfo() {
22         return new ApiInfoBuilder()
23                 .license("yibing")
24                 .title("xx系统API文档")
25                 .description("测试系统")
26                 .version("1.0")
27                 .build();
28     }
29 }

3. Controller注解

 1 @Slf4j
 2 @RestController
 3 @RequestMapping("/log")
 4 @Api(tags = "日志管理")
 5 public class LogController {
 6 
 7     @ApiOperation("链路追踪")
 8     @PostMapping("/trace")
 9     public TraceResponse log(@RequestBody @Validated TraceReq req) {
10         log.info("console log");
11         log.info("stop");
12         return new TraceResponse();
13     }
14 }

4.入参

@Data //必须要有，否则swagger不能读取属性
@ApiModel("链路追踪请求")
public class TraceReq {
    @ApiModelProperty(notes = "id", required = true)
    private String id;
}

5.出参

@Data
@ApiModel("链路追踪响应")
@AllArgsConstructor
public class TraceResponse {
    @ApiModelProperty(notes = "数据字符串", required = true)
    private String data;
}

6.配置项

#swagger启用开关
springfox.documentation.enabled=true


#Spring Boot 2.6.0 及以后版本中引入的一个配置属性，用于控制 Spring MVC 中的路径匹配策略
#这个配置的引入主要是为了解决一些向后兼容性问题，特别是与一些第三方库（如 Springfox Swagger）的兼容性问题
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

7.访问UI页面
