我有Windows 7主机.相同的程序在gradlew bootRun下运行良好.我没有使用web.xml.但是我的build.gradle符合 https://cloud.google .com/appengine/docs/standard/java/tools/gradle .我没有通过Eclipse运行(此处报告了类似的问题: mvn appengine:run-错误403(带有jsp的spring boot web)).springBootVersion ='2.0.0.BUILD-SNAPSHOT'

I have a Windows 7 host. The same program runs fine with gradlew bootRun.I am not using a web.xml. But my build.gradle is along the lines of https://cloud.google.com/appengine/docs/standard/java/tools/gradle.I am not running through eclipse (similar problem is reported here: mvn appengine:run - error 403 (spring boot web with jsp)).springBootVersion = '2.0.0.BUILD-SNAPSHOT'

build.gradle:

build.gradle:

buildscript {
    ext {
        springBootVersion = '2.0.0.BUILD-SNAPSHOT'
    }
    repositories {
        mavenCentral()

        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
