当应用程序启动并从测试中访问时,Spring Boot / Jersey 找不到处理程序方法。如果我单独启动应用程序并使用http://localhost:8080/demo
浏览器访问一切都很好。
日志说:“没有找到 [/demo] 的处理程序方法”。相关的日志输出:
2018-06-18 17:04:31.071 DEBUG 7628 --- [nio-8080-exec-1] o.s.web.reactive.DispatcherHandler : Processing GET request for [http://localhost:8080/demo]

该应用程序包含以下类(用 Kotlin 编写):
资源
import org.springframework.stereotype.Component
import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.ws.rs.core.Response
@Component
@Path("/")
class Resource {
@GET
@Path("demo")
fun test() = Response.ok("Hi!").encoding("UTF-8").build()
}
JerseyConfig
import org.glassfish.jersey.server.ResourceConfig
import org.springframework.stereotype.Component
@Component
class JerseyConfig : ResourceConfig() {
init {
register(Resource::class.java)
}
}
应用程序:
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
@SpringBootApplication
class App
fun main(args: Array<String>) {
runApplication<App>(*args)
}
失败的测试:
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.TestInstance
import org.junit.jupiter.api.extension.ExtendWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.test.context.junit.jupiter.SpringExtension
import org.springframework.test.web.reactive.server.WebTestClient
@ExtendWith(SpringExtension::class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
class ResourceTest {
@Autowired
lateinit var client: WebTestClient
@Test
fun getTest() {
client.get().uri("demo").exchange().expectStatus().isOk
}
}
如果我使用 Jersey 客户端进行测试,我会得到同样的错误:
@Test
fun testWithJersey() {
val client = ClientBuilder.newClient()
val response = client.target("http://localhost:8080/demo").request().get()
assertThat(response.status).isEqualTo(200)
}
构建.gradle:
buildscript {
ext {
kotlinVersion = '1.2.50'
springBootVersion = '2.0.3.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}")
classpath("org.jetbrains.kotlin:kotlin-allopen:${kotlinVersion}")
}
}
apply plugin: 'kotlin'
apply plugin: 'kotlin-spring'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
compileKotlin {
kotlinOptions {
freeCompilerArgs = ["-Xjsr305=strict"]
jvmTarget = "1.8"
}
}
compileTestKotlin {
kotlinOptions {
freeCompilerArgs = ["-Xjsr305=strict"]
jvmTarget = "1.8"
}
}
repositories {
mavenCentral()
}
dependencies {
compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
compile("org.jetbrains.kotlin:kotlin-reflect")
compile('org.springframework.boot:spring-boot-starter-jersey')
testCompile("org.springframework.boot:spring-boot-starter-test") {
exclude group: "junit", module: "junit"
}
testCompile('org.springframework.boot:spring-boot-starter-webflux')
testCompile("org.junit.jupiter:junit-jupiter-api")
testRuntime("org.junit.jupiter:junit-jupiter-engine")
}
测试代码本身似乎没问题,因为当我将测试方法的主体替换为Thread.sleep(...)
然后从浏览器访问服务器时,我得到了同样的错误(404,由于“没有找到 [/demo] 的处理程序方法” )。
为什么在测试中找不到处理程序方法?我必须改变什么?
