Springboot集成Swagger-ui完美方案，不显示api解决

1. 建立maven项目,导入依赖

   
	
		org.springframework.boot
		spring-boot-starter-parent
		2.1.3.RELEASE
		  
	
    
	
		1.8
	
	
        
        
			org.springframework.boot
			spring-boot-starter-web
		
		
			org.springframework.boot
			spring-boot-starter-test
			test
		
        
		
			org.springframework.boot
			spring-boot-devtools
			runtime
				
		
		
			io.springfox
			springfox-swagger2
			2.5.0
		
		
			io.springfox
			springfox-swagger-ui
			2.5.0
		
		
			io.springfox
			springfox-staticdocs
			2.5.0
		
	

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/", "[email protected]"))//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
