我是Spring Boot和微服务的新手。 我正在使用sql server作为演示微服务应用程序的数据库。我要在应用程序执行开始时创建一个数据库（如果除了要添加的多个参数之外不存在该数据库），以下是我创建的application.properties文件，但是spring.datasourse行。网址失败。
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=Hello?useUnicode=true&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true&allowPublicKeyRetrieval=true&useSSL=false
spring.datasource.username=sa
spring.datasource.password=Temp1234
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.show-sql=true
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2008Dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.SQLServer2008Dialect
spring.jpa.properties.hibernate.format_sql = true
spring.jpa.hibernate.ddl-auto = none
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.liquibase.change-log=classpath:/db/changelog/db.changelog-master.xml
但是如果在执行过程中引发了休闲错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [org/springframework/boot/autoconfigure/liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: Invocation of init method failed; nested exception is liquibase.exception.DatabaseException: com.microsoft.sqlserver.jdbc.SQLServerException: The databaseName property exceeds the maximum number of 128 characters.

问题出在连接字符串中。
尝试不使用[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}
# ^
根据您的xml，您的数据库名称为`user'。因此，尝试：
databaseName
