当使用 Spring Boot 版本 1.5.1.RELEASE 启用 Vaadin 8 Push 时，我收到以下错误。

这是 build.gradle

buildscript {
    ext {
        springBootVersion = '1.5.1.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'test'
    version = '0.0.1-SNAPSHOT'
}

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-jersey')
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')

    // Spring Boot Security
  compile("org.springframework.boot:spring-boot-starter-security")
  compile("org.springframework.security.oauth:spring-security-oauth2")
  compile('org.springframework.security:spring-security-ldap')

  // Spring Actuator
  compile("org.springframework.boot:spring-boot-starter-actuator")

  // Vaadin
  compile('com.vaadin:vaadin-spring-boot-starter')
  compile('com.vaadin:vaadin-push')

  // Vaadin add-ons
  compile("org.vaadin.spring.addons:vaadin-spring-addon-eventbus:0.0.7.RELEASE")
  compile("org.vaadin.spring.addons:vaadin-spring-addon-mvp:0.0.7.RELEASE")
  compile("org.vaadin.spring.addons:vaadin-spring-addon-i18n:0.0.7.RELEASE")

  //Vaadin extentions - in the future more of those will go to official VaadinSpring Integration
  compile("org.vaadin.spring.extensions:vaadin-spring-ext-security:0.0.7.RELEASE")
  compile("org.vaadin.spring.extensions:vaadin-spring-ext-core:0.0.7.RELEASE")
  compile("org.vaadin.spring.extensions:vaadin-spring-ext-boot:0.0.7.RELEASE")
  compile("org.vaadin.spring.extensions:vaadin-spring-ext-test:0.0.7.RELEASE")

  // lombok
  compileOnly('org.projectlombok:lombok')

}

dependencyManagement {
    imports {
        mavenBom "com.vaadin:vaadin-bom:8.0.0"
    }
}

如果我禁用 compile('com.vaadin:vaadin-push')，则没有错误，但 push 不起作用。您知道如何使用 Vaadin 8 和 Spring Boot 5 进行推送吗？

此类自 Spring Boot 1.4 以来已被弃用，并在 1.5 版本中删除。降级到 Spring Boot 1.4.5.RELEASE 并等待 Vaadin 使用正确的类。

当我升级到 Vaadin4Spring 2.0.0.RELEASE 时，此问题已得到修复。

编译("org.vaadin.spring.addons:vaadin-spring-addon-eventbus:2.0.0.RELEASE") 编译("org.vaadin.spring.extensions:vaadin-spring-ext-security:2.0.0.RELEASE ")
