1、依赖
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
注：Springfox 3.0.0（包含springfox-swagger2-3.0.0）即OpenAPI 3的发布与系统集成
启动项目，访问地址：http://localhost:8080/swagger-ui/index.html
2、application.yml配置
spring:
application:
name: springfox-swagger
server:
port: 8080
# ===== 自定义swagger配置 ===== #
swagger:
enable: true
application-name: ${
spring.application.name}
application-version: 1.0
application-description: springfox swagger 3.0整合Demo
try-host: http://localhost:${
server.port}
3、自定义swagger配置类SwaggerProperties
@Component
@ConfigurationProperties("swagger")
public class SwaggerProperties {
/**
* 是否开启swagger，生产环境一般关闭，所以这里定义一个变量
*/
private Boolean enable;
/**
* 项目应用名
*/
private String applicationName;
/**
* 项目版本信息
*/
private String applicationVersion;
/**
* 项目描述信息
*/
private String applicationDescription;
/**
* 接口调试地址
*/
private String tryHost;
public Boolean getEnable() {
return enable;
}
public void setEnable(Boolean enable) {
this.enable = enable;
}
public String getApplicationName() {
return applicationName;
}
public void setApplicationName(String applicationName) {
this.applicationName = applicationName;
}
public String getApplicationVersion() {
return applicationVersion;
}
public void setApplicationVersion(String applicationVersion) {
this.applicationVersion = applicationVersion;
}
public String getApplicationDescription() {
return applicationDescription;
}
public void setApplicationDescription(String applicationDescription) {
this.applicationDescription = applicationDescription;
}
public String getTryHost() {
return tryHost;
}
public void setTryHost(String tryHost) {
this.tryHost = tryHost;
}
}
