Spring Boot 默认测试抛出 IllegalStateException

【问题描述】：

我开始使用 Spring Boot，但我在全新安装时遇到了问题。

我已经使用http://start.spring.io 创建了初始项目。这是我的 build.gradle：

buildscript {
    ext {
        springBootVersion = '1.2.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") 
        classpath("io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot' 
apply plugin: 'io.spring.dependency-management' 

jar {
    baseName = 'springboot-demo1'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile("org.springframework.boot:spring-boot-starter-jdbc")
    runtime("mysql:mysql-connector-java")
    testCompile("org.springframework.boot:spring-boot-starter-test") 
}


eclipse {
    classpath {
         containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
         containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8'
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

当我在命令行中执行时：

gradlew clean build

构建失败。这是输出：

D:\springboot-demo1>gradlew clean build
:clean
:compileJava
:processResources
:classes
:jar
:findMainClass
:startScripts
:distTar
:distZip
:bootRepackage

:compileTestJava
:processTestResources UP-TO-DATE

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test'.
> There were failing tests. See the report at: file:///D:/springboot-demo1/build/reports/tests/index.html

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 17.572 secs

测试失败。 这是失败的测试类代码：

package info.gandraweb.faker.apns;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.SpringApplicationConfiguration;
import static org.junit.Assert.*;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = JavaApnsFakerApplication.class)
public class JavaApnsFakerApplicationTests {

    @Test
    public void contextLoads() {
        assertTrue(true);
    }

}

这是全新安装的 Spring Boot，会立即失败。我必须做些什么才能使构建通过和测试执行而没有任何错误？

【问题讨论】：

  • "使用 --stacktrace 选项运行以获取堆栈跟踪"。发布堆栈跟踪可能会帮助您获得答案
  • 查看测试报告文件：///D:/springboot-demo1/build/reports/tests/。打开报告，粘贴测试失败的堆栈跟踪。
  • @jb-nizet，我已经用 build\reports\tests\index.html 文件中的完整堆栈跟踪更新了帖子
  • “无法确定数据库类型 NONE 的嵌入式数据库驱动程序类。”。按照docs.spring.io/spring-boot/docs/current/reference/html/… 中的说明进行操作

标签： java spring gradle spring-boot


【解决方案1】：

确保您在 application.properties 中有连接属性

例如。

spring.datasource.url=jdbc:mysql://localhost/database
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

【讨论】：

  • 如果我在构建时将这些连接属性作为参数传递怎么办？
  • @gkc 会起作用的。我假设您正在使用 Spring Boot。在这种情况下，您可以运行以下命令：java -jar my-app.jar --spring.datasource.url=jdbc:mysql://localhost/database --spring.datasource.username=username --spring.datasource.password=password --spring.datasource.driver-class-name=com.mysql.jdbc.Driver
  • 非常有用的提示 - 谢谢。在我们的例子中，我们依靠来自 jenkins 服务器的 ssh 隧道连接到远程数据库。重启后这条隧道已经关闭，我们得到的堆栈跟踪非常少。
【解决方案2】：

我遇到了类似的问题，但在 JPA 模块中使用了 Spring Initializr。发生的情况是，在生成的 pom.xml 中，没有为任何嵌入式数据库声明依赖项。这使得上下文加载过程在测试阶段失败。

要修复，您只需将以下依赖项添加到您的pom.xml：

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <scope>runtime</scope>
</dependency>

但是我认为默认情况下有这样的依赖会很好，所以我在 Spring 打开了一个（微不足道的）问题：

https://jira.spring.io/browse/DATAJPA-1461

我希望我已经提交给正确的董事会。

【讨论】：

  • 你的解决方案帮助了我。谢谢
