我正在尝试从Spring启动应用程序中的服务执行Junit 4测试，并且我继续使用init获取entityManagerFactory。
我也希望使用我的application.properties文件进行连接，但是它想使用嵌入式hsqldb进行连接。
有人能指出我正确的方向吗？
以下是相关代码：
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/finra?useSSL=false
# Username and password
spring.datasource.username = finra
spring.datasource.password = finra
# 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
spring.jpa.hibernate.ddl-auto = update
# 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
