spring-swagger获取接口url和接口名称
在spring boot 项目，很多使用 swagger 做接口文档编写。但是怎么集中获取 项目内接口url。通过查看 swagger接口，提取如下代码
参考：springboot获取所有URL和swagger注解参数

工具类

抱歉给漏了自定义类了

package cn.xxx.xxx.xx.commons.web;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

/**
 * SpringBeanManage 类说明:
 *
 * @version v1.0
 * @date 2021/11/15
 */
@Component
public class SpringBeanManage implements ApplicationContextAware {
    private static ApplicationContext context;

    @Override
    public void setApplicationContext(ApplicationContext context) throws BeansException {
        if (null == SpringBeanManage.context){
            SpringBeanManage.context = context;
        }
    }

    public static ApplicationContext getContext() {
        return context;
    }
    public static <T> T getBean(String name,Class<T> clazz){
        return getContext().getBean(name, clazz);
    }
    public static <T> T getBean(String name){
        return (T) getContext().getBean(name);
    }
    public static <T> T getBean(Class<T> clazz){
        return getContext().getBean(clazz);
    }
    public static boolean contain(String name){
        return getContext().containsBean(name);
    }
}
