【问题描述】：

我正在学习弹簧靴。我创建了一个名为 student 的数据库，我想使用 spring-boot 访问它。但是当我运行项目时，我会出现这个错误，但是我没有在 postgresql 中的任何角色上配置任何密码。我试过用谷歌搜索，但我没弄好。

这是我开始运行项目时遇到的错误。我需要帮助沟通。

我的 application.properties 如下

spring.datasource.url=jdbc:postgresql://localhost:5432/student
spring.datasource.username=enock
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.format_sql=true

而pom.xml中的postgres依赖如下

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

【问题讨论】：

您是如何创建数据库的？您应该首先使用通用数据库客户端（例如psql 或pgAdmin）验证连接。
如何验证连接？因为我刚刚创建了一个名为 student 的数据库。请通过更多的光线
您可以安装和使用pgAdmin。但我仍然想知道您最初是如何创建数据库的。
创建数据库学生；然后我为两个用户“postgres”和“enock”添加了权限。
然后设置密码：ALTER USER enock PASSWORD 'root';

标签： java spring postgresql spring-boot jpa

【解决方案1】：

我遇到了完全相同的问题。我所做的是创建一个新用户并授予所有权限。打开 cmd 并输入： psql -U postgres 确保将 postgress 添加到路径中。然后创建一个用户： create user user_name with encrypted password 'password';最后：将数据库 db_name 的所有权限授予“用户名”；这就是我在 application.properties 上的内容：

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/db_name
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.database- 
platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
spring.sql.init.mode=always   
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation = 
true

在 pom.xml 中我添加了：

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
   <groupId>org.postgresql</groupId>
   <artifactId>postgresql</artifactId>
   <version>${postgresql.version}</version>
</dependency>
