我已经将MS-SQL与Spring Boot应用程序集成在一起。但是在启动时,出现以下错误。
无法实例化[org.apache.tomcat.jdbc.pool.DataSource]:工厂方法'dataSource'抛出异常;嵌套的异常是java.lang.NullPointerException。
下面是堆栈跟踪:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.NullPointerException

下面是application.properties文件:
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase?verifyServerCertificate=false&useSSL=false&requireSSL=false
spring.datasource.username=<username>
spring.datasource.password=<password>
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
启动类:
@SpringBootApplication
public class CheckApplication {
public static void main(String[] args) {
SpringApplication.run(CheckApplication.class, args);
}
}
我还设置了spring.profiles.active

代替:
NHibernate.StaleObjectStateException
根据使用的数据库添加以下内容:
对于MS SQL
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
用于我的SQL
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver

也许mysql驱动程序配置不正确。 在pom.xml文件中(需要mysql依赖):
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
