SpringBoot整合Swagger框架 ,并设置接口请求头token默认值

引入maven依赖

  <!-- swagger2-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
</dependency> <!--防止进入swagger页面报类型转换错误,排除2.9.2中的引用,手动增加1.5.21版本-->
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.21</version>
</dependency> <dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-models</artifactId>
<version>1.5.21</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>

创建配置类

SwaggerConfig.java

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.env.Profiles;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2; import java.util.ArrayList; /**
* @author yvioo。
*/
@Configuration
@EnableSwagger2 //开启Swagger2
public class SwaggerConfig { /**
* 配置Swagger的Docket的bean实例
* @return
*/
@Bean
public Docket docket(Environment environment) { //设置只在开发中环境中启动swagger
Profiles profiles=Profiles.of("dev"); //表示如果现在是dev环境,则返回true 开启swagger
boolean flag=environment.acceptsProfiles(profiles); /*添加接口请求头参数配置 没有的话 可以忽略*/
ParameterBuilder tokenPar = new ParameterBuilder();
List<Parameter> pars = new ArrayList<>();
tokenPar.name("token").description("令牌").defaultValue("设置token默认值").modelRef(new ModelRef("string")).parameterType("header").required(false).build();
pars.add(tokenPar.build()); return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
//是否启动swagger 默认启动
.enable(flag)
//所在分组
.groupName("yvioo")
.select()
//指定扫描的包路径
.apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
//指定扫描的请求,这里表示扫描 /hello/ 的请求
//.paths(PathSelectors.ant("/hello/**"))
.build()
.globalOperationParameters(pars);
} /**
* 配置ApiInfo信息
* @return
*/
private ApiInfo apiInfo() { //作者信息
Contact author = new Contact("yvioo", "https://www.cnblogs.com/pxblog/", "111@qq.com"); return new ApiInfo(
"Swagger测试",
"Swagger描述",
"1.0",
"urn:tos",
author,
"Apache 2.0",
"http://www.apache.org/licenses/LICENSE-2.0",
new ArrayList()
); }
}

但是如果有其他配置继承了 WebMvcConfigurationSupport 就需要增加资源映射 不然会失效

@Configuration
public class WebMvcConfigurer extends WebMvcConfigurationSupport { /**
* 发现如果继承了WebMvcConfigurationSupport, 需要重新指定静态资源
*
*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**").addResourceLocations(
"classpath:/static/");
registry.addResourceHandler("swagger-ui.html").addResourceLocations(
"classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations(
"classpath:/META-INF/resources/webjars/");
super.addResourceHandlers(registry);
}
}

测试用户实体类

User.java

package com.example.demo.entity;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data; @ApiModel("用户实体类 User") //增加实体类接口注释
@Data //使用Lombok插件自动生成get set方法,这样才能在swagger中显示属性值
public class User { @ApiModelProperty("用户ID") //增加字段接口注释
private Integer id; @ApiModelProperty("用户名")
private String username; }

测试控制器

SwaggerController.java

package com.example.demo.controller;

import com.example.demo.entity.User;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@Api(description = "该控制器描述")
@RestController
public class SwaggerController { @GetMapping("/hello")
public String hello(){
return "hello";
} /**
* 接口返回值含有实体类,就会被swagger扫描
*
* @return
*/
@ApiOperation("查询用户方法注释")
@GetMapping(value = "/get/{id}")
public User get(@ApiParam("请求参数注释") @PathVariable(value = "id")Integer id){
return new User();
}
}

@ApiImplicitParam:
作用在方法上,表示单独的请求参数 
参数: 
1. name :参数名。 
2. value : 参数的具体意义,作用。 
3. required : 参数是否必填。 
4. dataType :参数的数据类型。

使用dev环境 启动项目后  浏览器打开http://localhost:8081/swagger-ui.html#/   我这里用的端口是8081
