java - 使用java和intellij连接到postgresql的问题

标签 java postgresql gradle heroku

我的项目有问题。我正在尝试使用 postgresql 启动我的应用程序，但出现错误。我无法调用 build gradle，总是完成 BUILD FAILED。我给你看代码。 我不明白为什么会出现这个错误，因为我花了一周时间没有出现问题，并且 gradle 构建也成功了。我刚刚将应用程序属性文件更改回 MySQL。当我再次想使用 postgresql 时，出现了这些错误。我正在寻求帮助，感谢您的每一个回答

我的应用程序属性

spring.jpa.hibernate.ddl-auto=update
spring.jpa.database=postgresql
spring.datasource.url=${JDBC_DATABASE_URL}
spring.datasource.username=${JDBC_DATABASE_USERNAME}
spring.datasource.password=${JDBC_DATABASE_PASSWORD}

我的build.gradle

plugins {
    id 'org.springframework.boot' version '2.1.3.RELEASE'
    id 'java'
}

apply plugin: 'io.spring.dependency-management'

//应用插件:'war'

group = 'com.crud'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    compileOnly 'org.projectlombok:lombok:1.18.8'
    annotationProcessor 'org.projectlombok:lombok:1.18.8'
    implementation 'org.springframework.boot:spring-boot-starter-data- 
   jpa'
    //runtimeOnly 'mysql:mysql-connector-java'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'io.springfox:springfox-swagger2:2.7.0'
    implementation 'io.springfox:springfox-swagger-ui:2.7.0'
    testImplementation 'org.springframework.boot:spring-boot-starter- 
   test'
    runtimeOnly 'org.postgresql:postgresql'
    implementation 'org.springframework.boot:spring-boot-starter- 
   mail:2.1.5.RELEASE'
    //providedRuntime 'org.springframework.boot:spring-boot-starter- 
    tomcat'
}

当我运行应用程序时...

当我运行 gradle build 时...

Task :test

最佳答案

我认为日志说明了问题所在。

'dataSource' threw exception; nested exception is java.lang.IllegalArgumentException: URL must start with 'jdbc' at

不清楚这个变量的值是什么${JDBC_DATABASE_URL}

但它应该是这样的:

jdbc:postgresql://localhost:5432/dbname?currentSchema=dbschema
