带有 netty 的 spring-web-flux 错误“反射 setAccessible(true) 已禁用”

Question

我有一个像上面一样的 junit 测试，但是当我启动测试时，我收到这个错误（JDK 13.0.1）：

java.lang.UnsupportedOperationException: Reflective setAccessible(true) disabled
java.lang.IllegalAccessException: class io.netty.util.internal.PlatformDependent0$6 cannot access class jdk.internal.misc.Unsafe (in module java.base) because module java.base does not export jdk.internal.misc to unnamed module @4a94ee4

我的工具是 Intellij CE Edition 2019.3.1。这是我的类和 pom 文件：

    import org.junit.jupiter.api.Assertions;
    import org.junit.jupiter.api.Test;
    import org.springframework.web.reactive.function.client.WebClient;
    import reactor.core.publisher.Flux;

    class WebClientStockClientIntegrationTest {

        private static final String SYMBOL = "EUR";
        private WebClient webClient = WebClient.builder().build();

        @Test
        void shouldRetrieveStockPricesFromStockService() {
            WebClientStockClient webClientStockClient = new WebClientStockClient(webClient);
            Flux<StockPrice> prices = webClientStockClient.pricesFor(SYMBOL);
            Assertions.assertNotNull(prices);
            Assertions.assertTrue(prices.take(5).count().block() > 0);
        }
}

我的带有 spring-boot 和依赖项的 pom：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
        ..

    <properties>
        <java.version>11</java.version>
    </properties>

我解决了：我添加：

--add-opens java.base/jdk.internal.misc=ALL-UNNAMED -Dio.netty.tryReflectionSetAccessible=true

到我的测试配置
