我需要你的帮助。我正在尝试从springboot+mysql+jpa启动一个新的应用程序。连接工作了一段时间后突然停止。我试图更改mysql驱动程序，但没有看到任何更改。
这是我的application.properties


# ===============================

# = DATA SOURCE

# ===============================

# Set here configurations for the database connection

# Connection url for the database "netgloo_blog"

spring.datasource.url = jdbc:mysql://localhost:3306/farmacia_da_natureza?useSSL=false

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

# Username and senha

spring.datasource.usuario = root
spring.datasource.senha = password

# Keep the connection alive if idle for a long time (needed in production)

spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# ===============================

# = JPA / HIBERNATE

# ===============================

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is

# stripped before adding them to the entity manager).

# Show or not log for each sql query

spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database

# schema will be automatically updated accordingly to java entities found in

# the project update

spring.jpa.hibernate.ddl-auto = drop-and-create

# Naming strategy

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Allows Hibernate to generate SQL optimized for a particular DBMS

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

例外情况是：

您使用了错误的属性名称，没有 spring.datasource.usuario 以及 spring.datasource.senha . 根据spring boot附录a，您需要：

spring.datasource.username = root
spring.datasource.password = password
