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
显示效果
