如何启用 Spring Security kotlin DSL？

Question

我们如何启用对 spring security kotlin DSL 的支持？

从 IDE (IntelliJ) 的屏幕截图中可以看出，DSL 不可用：

这是完整的SecurityConfig.kt 文件：

package com.example.backend.core

import org.springframework.context.annotation.Bean
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity
import org.springframework.security.config.web.server.ServerHttpSecurity
import org.springframework.security.web.server.SecurityWebFilterChain

@EnableWebFluxSecurity
class SecurityConfig {

  @Bean
  fun springSecurityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain? {
    return http {
      csrf { disable() }
      formLogin { disable() }
      httpBasic { disable() }
      // ...
    }
  }

}

这是我们的build.gradle.kts

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

val springBootVersion = "2.4.2"

plugins {
    id("org.springframework.boot") version "2.4.2"
    id("io.spring.dependency-management") version "1.0.11.RELEASE"
    kotlin("jvm") version "1.4.21"
    kotlin("plugin.spring") version "1.4.21"
}

group = "com.example"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_11

configurations {
    compileOnly {
        extendsFrom(configurations.annotationProcessor.get())
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    implementation("org.springframework.boot:spring-boot-starter-oauth2-resource-server")
    implementation("org.springframework.boot:spring-boot-starter-oauth2-client")
    implementation("org.springframework.boot:spring-boot-starter-security")
    implementation("org.springframework.boot:spring-boot-starter-webflux")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("io.projectreactor.kotlin:reactor-kotlin-extensions")
    implementation("org.flywaydb:flyway-core")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-reactor")
    developmentOnly("org.springframework.boot:spring-boot-devtools")
    runtimeOnly("io.micrometer:micrometer-registry-prometheus")
    runtimeOnly("org.postgresql:postgresql")
    annotationProcessor("org.springframework.boot:spring-boot-configuration-processor")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
    testImplementation("io.projectreactor:reactor-test")
    testImplementation("org.springframework.security:spring-security-test")
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "11"
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

这是 intellij 版本：

IntelliJ IDEA 2020.3 (Community Edition)

我们错过了一些依赖吗？它是否需要任何特定的 intellij 设置？

Answer 1

您需要手动导入ServerHttpSecurityinvoke。

import org.springframework.security.config.web.server.invoke

由于 1.4 中的 this Kotlin issue，IDE 并未按应有的方式向您建议。

这计划在 Kotlin 1.4.30 中修复。

Answer 2

我注意到您的问题是关于 WebFlux，但只是补充 @Eleftheria 的答案。

对于WebMvc 的人，您应该导入：

import org.springframework.security.config.web.servlet.invoke

（servlet 与服务器）

Answer 3

这个 DSL 从 Spring Security 5.3 版本开始内置。例如org.springframework.security:spring-security-config:5.3.4.RELEASE 库有它：org.springframework.security.config.web.servlet.HttpSecurityDsl#csrf 并且例如

compile group: 'org.springframework.boot', name: 'spring-boot-starter-security', version: '2.3.3.RELEASE'

库将包含它。
