aop：
MyInterceptor类：
拦截请求并打印请求信息，同时设置请求拦截除非白名单中有该请求路径否则不放行，具体可见代码：

RequestPermission注解
自定义权限控制注解，注解方法为以上PermissionAspect类中方法，可自行修改，本例写的比较简单，可根据项目需要修改编写：
import com.travel.term.common.constant.PermissionConstant;
import java.lang.annotation.*;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented // 在生成javac时显示该注解的信息
public @interface RequestPermission {
//设置一个权限名称,默认为读权限
String name() default PermissionConstant.READ;
}

maven打包，可直接使用idea的maven插件
在traget下有个打包完的jar包
部署
将jar包在服务器上启动
使用命令如下：
#后台启动 nohup java -jar -Xms128m -Xmx256m travel-system-0.0.1-SNAPSHOT.jar >/dev/null 2>&1 &
通过指令查看是否运行成功
ps -ef | grep travel-system-0.0.1-SNAPSHOT.jar
