Spring boot Data JPA task :test Failed

Question

我开始使用Data JPA从Spring与Postgres数据库交互，但是当我试图构建项目时，构建阶段在applicationTest中引发异常。

这是我的build.gradle:

plugins {
id 'org.springframework.boot' version '2.5.2'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'eu.universome.radio'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
dependencies {

implementation 'org.springframework.boot:spring-boot-starter-web'
//implementation 'org.springframework.boot:spring-boot-starter-jdbc'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
test {
useJUnitPlatform()
}

如果我注释依赖项:implementation 'org.springframework.boot:spring-boot-starter-data-jpa'构建将会成功。

这是我的空applicationTest:

package eu.universome.radio.RadioUVMServer;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class RadioUvmServerApplicationTests {
@Test
void contextLoads() {
}
}

这里有控制台错误:

Answer 1

1. 不确定是否添加了依赖项

implementation group: 'org.postgresql', name: 'postgresql', version: '42.2.23'

2. 您可以检查驱动程序是否在类路径上:

try {
Class.forName("org.postgresql.Driver");
} catch (ClassNotFoundException e) {
// recheck dependencies
}

Answer 2

解决了添加行

runtimeOnly 'org.postgresql:postgresql'

build.gradle 依赖

dependencies {

implementation 'org.springframework.boot:spring-boot-starter-web'
//implementation 'org.springframework.boot:spring-boot-starter-jdbc'
implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
runtimeOnly 'org.postgresql:postgresql'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
