"""field__test' = '"a"') OR 1 = 1 OR ('d""": 'x',
})

与Tutorial · Building web applications with Spring Boot and Kotlin相同
为什么会出现此错误？我正在写一个控制器作为教程。
导入目标是否不同？ 还是gradle版本不同？
HtmlController.ktbuild.gradle.kts
package com.example.blog
import org.springframework.stereotype.Controller
import org.springframework.ui.Model
import org.springframework.ui.set
import org.springframework.web.bind.annotation.GetMapping
@Controller
class HtmlController {
@GetMapping("/")
fun blog(model: Model): String {
model["title"] = "Blog"
return "blog"
}
}

Tutorial · Building web applications with Spring Boot and Kotlin
Gradle Build部分中的教程说。
依赖关系3此类Spring需要Kotlin特定的库 引导Web应用程序并默认配置：
因此需要将其添加到build.gradle.kts。
dependencies {
implementation("org.springframework.boot:spring-boot-starter-data-jpa")
implementation("org.springframework.boot:spring-boot-starter-mustache")
implementation("org.springframework.boot:spring-boot-starter-web")
implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
implementation("org.jetbrains.kotlin:kotlin-reflect")
implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
runtimeOnly("com.h2database:h2:1.4.200") // See https://github.com/spring-projects/spring-boot/issues/18593 and https://github.com/h2database/h2database/issues/1841
runtimeOnly("org.springframework.boot:spring-boot-devtools")
testImplementation("org.springframework.boot:spring-boot-starter-test")
}
我没有像@ M.Deinum所说的那样做
