Spring Boot无法读取yml属性文件

Question

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

spring.datasource.url=jdbc:mysql://localhost:3306/db_name?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=true
spring.jpa.show-sql=true

在Yaml我有：

 spring:
        datasource:
            url: "jdbc:mysql://localhost:3306/db_name?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC"
            driver-class-name: com.mysql.cj.jdbc.Driver
            username: "username"
            password: "password"
        jpa:
            hibernate:
                ddl-auto: update
            generate-ddl: true
            show-sql: true

我认为您必须将“从

url: "jdbc:mysql://localhost:3306/db_name?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC"

让它像跟随

 url: jdbc:mysql://localhost:3306/db_name?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
