spring boot 集成 springfox 3.0.0

springfox 3.0.0 上线之后，调整自己的工程

1. pom中添加依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.78</version>
</dependency>
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

2. 在main主入口中添加注解@EnableOpenApi

@SpringBootApplication
@EnableOpenApi
public class SpringfoxApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringfoxApplication.class, args);
    }

}
3. 配置swaaper UI的配置

package com.example.springfox.config;

        try {

            List<InterceptorRegistration> registrations = (List<InterceptorRegistration>) ReflectionUtils.getField(registrationsField, registry);
            if (registrations != null) {
                for (InterceptorRegistration interceptorRegistration : registrations) {
                    interceptorRegistration
                            .excludePathPatterns("/swagger**/**")
                            .excludePathPatterns("/webjars/**")
                            .excludePathPatterns("/v3/**")

                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

创建属性配置文件：
package com.example.springfox.config;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * @author: hett
 * @date: 2022/1/17 8:54
 */
@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;
    }
}
yaml配置文件

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}

4. 使用

@SpringBootApplication
@EnableWebMvc
public class SpringfoxApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringfoxApplication.class, args);
    }

}

@Api(tags = "fox测试")
@RestController
@RequestMapping("/fox")
public class SpringFoxController {

    @ApiOperation("获取fox测试")
    @GetMapping("/geTest")
    public JSONObject get(){
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("id",1);
        return jsonObject;
    }
}

5. 测试
