tomcat启动 web.xml在WEB-INF目录下，web.xml什么也没有配置，启动也是报这个错

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

</web-app>

把工程配置好以后，用IDEA启动tomcat的时候报的web.xml拒绝访问的错。

apply plugin: 'java'
apply plugin: 'war'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
    testCompile group: 'junit', name: 'junit', version: '4.12'
    compile group: 'org.nutz', name: 'nutz', version: '1.r.60'
    compile group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'
}

恩恩 web.xml路径跟你写得一样

可能是工程不干净，新建一个工程好了，谢谢作者一直积极帮忙解决问题。
