spring boot集成swagger3
spring boot集成swagger3
swagger2的整合:https://www.cnblogs.com/chenglc/p/10910721.html
swagger3的使用步骤和2略有差异
maven依赖
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
swagger3.0的依赖将springfox-swagger-ui
和springfox-swagger2
整合到了springfox-boot-starter
,还包括一些spring的依赖,说一不需要再去关心其他的依赖。
开启swagger
和2版本一样,需要一个swagger的配置,用于配置基本信息
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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
/**
* swagger配置
*/
@Configuration
public class SwaggerConfig {
Boolean swaggerEnabled = true;
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.OAS_30)
.apiInfo(apiInfo())
// 是否开启
.enable(swaggerEnabled)//true
.select()
.apis(RequestHandlerSelectors.basePackage("com.clc.resource"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("资源中心swagger业务")
//创建人
.contact(new Contact("clc", "http://www.baidu.com", "[email protected]"))
.version("1.0")
.description("不需要描述")
.build();
}
}
默认访问地址
http://localhost:port/swagger-ui/index.html
和2版本地址不同:http://localhost:port/swagger-ui.html
spring boot 2.6.x 版本配置
如果是spring boot 2.6.x集成了swagger,会出现异常信息:
Failed to start bean 'documentationPluginsBootstrapper';
org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

因为Springfox使用的路径匹配是基于AntPathMatcher的,而Spring Boot 2.6.X使用的是PathPatternMatcher
解决方案
加spring配置指定AntPathMatcher
spring.mvc.pathmatch.matching-strategy: ANT_PATH_MATCHER
使用示例
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
/**
* ClassName: JSR303Controller
* Description:JSR303协议测试
*
* @author chengluchao
* @date: 2022/1/11 14:49
* @since 1.3.9
*/
@Api("JSR303协议")
@Validated
@RestController
@RequestMapping("/jsr303")
@Slf4j
public class JSR303Controller {
@ApiOperation("批量保存数据")
@ResponseBody
@PostMapping("batchSave")
public Object batchSave(@RequestBody @Validated(ValidationGroupSequence.class) BatchSysGroupDto dto) {
return "Result.okInstance();";
}
}
效果
swagger3.0新功能
- Webflux支持
- Spring Integration支持
- SpringBoot支持springfox Boot starter依赖性(零配置、自动配置支持)
- 支持OpenApi 3.0.3
