简介
controller类里的方法前@RequestMapping注释的路由信息获取，如下图所示相关代码
RouteList.javapackage com.ffan.util;import org.springframework.beans.factory.config.BeanDefinition;import org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider;import org.springframework.core.type.filter.AnnotationTypeFilter;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import java.util.Arrays;import java.util.Set;public class RouteList {    public static void main(String[] args) throws ClassNotFoundException {        ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);        scanner.addIncludeFilter(new AnnotationTypeFilter(Controller.class));        Set<BeanDefinition> beanSet = scanner.findCandidateComponents("com.ffan.smartlife.controller");        for (BeanDefinition def : beanSet) {            Class<?> clazz = Class.forName(def.getBeanClassName());            Arrays.stream(clazz.getDeclaredMethods()).map(m -> m.getAnnotation(RequestMapping.class)).filter(                    a -> a != null && a.value().length > 0).forEach(                    a -> Arrays.stream(a.value()).forEach(                            p -> {                                System.out.println(p);                            }                    ));        }    }}
效果图
设计要点
通过ClassPathScanningCandidateComponentProvider获取spring boot框架的元数据
获取controller信息
获取controller里的注解RequestMapping信息
