访问注解：

 t = Class.forName(className);                //请求配置                Class<RequestMapping> annClass = org.springframework.web.bind.annotation.RequestMapping.class;                //api 解释                Class<ApiExplain> annApiExplain = com.sinky.api.ApiExplain.class;                //权限                Class<RequiresRoles>  annRequiresRoles =  org.apache.shiro.authz.annotation.RequiresRoles.class;                //请求                Annotation annotationClass = t.getAnnotation(annClass);                //api类注释                Annotation annotationClassDescription = t.getAnnotation(annApiExplain);                classStr = getAnnValues(annotationClass);                if (null == classStr)                    continue;                System.out.println("类注解：" + classStr);                Method[] methods = t.getMethods();                for (Method m : methods)                {                                     methodStr =                        getAnnValues(m.getAnnotation(annClass),                            annotationClass,                            m.getName(),                            className,                            m.getAnnotation(annApiExplain),                            annotationClassDescription,                            m.getAnnotation(annRequiresRoles)                            );                    if (null == methodStr)                        continue;                    System.out.println("方法:" + m.getName() + " " + methodStr);                }                            }            catch (ClassNotFoundException e)            {                e.printStackTrace();            }

自定义注解：

import java.lang.annotation.Documented;import java.lang.annotation.ElementType;import java.lang.annotation.Retention;import java.lang.annotation.RetentionPolicy;import java.lang.annotation.Target;import org.springframework.web.bind.annotation.Mapping;/** *  * 用于提供api注释 * <功能详细描述> *  * @author  liubeihua * @version  [版本号, 2016年1月13日] */@Target({ElementType.METHOD, ElementType.TYPE})@Retention(RetentionPolicy.RUNTIME)@Documented@Mappingpublic @interface ApiExplain{    /**     *  描述     * @return     */    String description() default "";    String other() default "";    String value() default "";}
