Springboot集成Swagger-ui完美方案，不显示api解决_swagger中没有不同的api可 选

1. 建立maven项目,导入依赖

   <!--加入springboot-->
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.1.3.RELEASE</version>
		<relativePath />  
	</parent>
    <!--JDK版本-->
	<properties>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>
        <!--Springboot web和测试依赖 -->
        <dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
        <!-- 有更改时重新启动springboot方便调试-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<scope>runtime</scope>
		</dependency>		
		<!-- swagger2依赖 -->
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
			<version>2.5.0</version>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger-ui</artifactId>
			<version>2.5.0</version>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-staticdocs</artifactId>
			<version>2.5.0</version>
		</dependency>
	</dependencies>

2. 建立springboot启动类

package com.tpdog.app;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@SpringBootApplication
@EnableSwagger2
public class TpdogApp {
 
	public static void main(String[] args) {
		SpringApplication.run(TpdogApp.class, args);
		System.out.println("springboot启动成功");
	}
}

建立swagger2配置类

package com.tpdog.app;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@ComponentScan("com.tpdog.controller")//需要扫描的api位置
@Configuration//说明是一个配置类
@EnableSwagger2//支持swagger2
public class SwaggerConfig {
 
	/**
     * 创建BeanApi
     * apiInfo() 增加API相关信息
     * 通过select()函数返回一个ApiSelectorBuilder实例,用来控制哪些接口暴露给Swagger来展现，
     * 本例采用指定扫描的包路径来定义指定要建立API的目录。
     *
     * @return
     */
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.tpdog"))//扫描Api包
                .paths(PathSelectors.any())
                .build();
    }
 
    /**
     * 创建该API的基本信息（这些基本信息会展现在文档页面中）
     * 访问地址：http://项目实际地址/swagger-ui.html
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Springboot-Swagger示例")//api的标日
                .description("一般常用api信息")//api描述
                .termsOfServiceUrl("https://www.baidu.com/")//服务地址
                .contact(new Contact("cqc", "https://www.baidu.com/", "leomple@163.com"))//联系信息
                .version("1.0")
                .build();
    }
}

3. 编写API类

package com.tpdog.controller;
 
import javax.servlet.http.HttpServletRequest;
 
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
 
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
 
@Controller
@RequestMapping("/dateapi")
@Api(value = "日期管理API")
public class DateController {
 
	@RequestMapping(value = "/date", method = RequestMethod.GET)
	@ResponseBody
	@ApiImplicitParam(paramType = "query",name= "cityid" ,value = "城市id",dataType = "string")
	@ApiOperation(value = "通过城市id获取天气信息", notes="返回城市天气信息")
	public ResponseEntity<Object> getDateInfo(HttpServletRequest request) {
		return new ResponseEntity<>(HolidayApi.getHoliday("s"), HttpStatus.OK);
	}
}

4. 启动Springboot启动类，在浏览器中输入：http://localhost:8099/swagger-ui.html

记住两处的端口要对应，默认的是8080，如需修改端口则在src/main/resources下建立application.properties文件并加入server.port=8099    然后保存，8099随意加的可以加入自己喜欢的四位端口号，值尽量大一些，推荐使用8080以后的重新启动Springboot启动类在浏览器中输入：http://localhost:8099/swagger-ui.html访问

一般常见问题，下面问题要修改端口号，参照4当中的操作，修改端口号。访问api地址不显示controller，是由于在SwaggerConfig类中没有加入@ComponentScan("你的controller包路径"),扫描api包的路径即可显示
