springBoot项目用logback将日志写到MySQL数据库

• 添加依赖

		<dependency>
            <groupId>commons-dbcpgroupId>
            <artifactId>commons-dbcpartifactId>
            <version>1.4version>
        dependency>

        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            
            <scope>runtimescope>
        dependency>

• 配置文件中添加相关配置(我的配置文件名称是application.properties)

  spring:
    datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
    url: jdbc:mysql:///localhost:3306/your database?characterEncoding=UTF-8

• 添加logback-test.xml文件,其中包含对于日志输出的一些设置,注意下图红框中上午内容:一定记得把数据库信息改成自己的,然后需要注意的是如果数据库的版本在6以下,要注意配置文件的驱动是com.mysql.jdbc.Driver而不是com.mysql.cj.jdbc.Driver
  resource下面的logback-test.xml文件的内容如下:

• 找到下面的文件,根据其中的SQL创建数据库+表:
  
• 添加测试类的依赖以及测试类(注意scope的属默认即可,即为compile,不能是test)

		<dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-testartifactId>

        dependency>

@RunWith(SpringRunner.class)
@SpringBootTest
public class LogbackTest {

    private final Logger logger= LoggerFactory.getLogger(LogbackTest.class);

    @Test
    public void LogToSql(){
        logger.info("数据库日志info");
        logger.error("数据库日志error");
    }
}

运行测试类即可成功看到结果:
