在Spring Boot 1.2.1中添加druid-spring-boot-starter 1.1并不是一个具体的问题，而更像是一个需求或操作步骤。如果您想了解如何在Spring Boot 1.2.1中添加druid-spring-boot-starter 1.1，请按照以下步骤进行操作：
1. 打开项目的
pom.xml文件。 2. 在<dependencies>标签内添加以下依赖项：xml <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency>3. 保存并关闭pom.xml文件。 4. 使用构建工具（如Maven）重新构建项目，以便下载并添加新的依赖项。 5. 在您的Spring Boot应用程序中配置Druid连接池。您可以通过在application.properties文件中添加以下属性来完成配置： ```properties # 数据源配置 spring.datasource.url=jdbc:mysql://localhost:3306/db_name spring.datasource.username=username spring.datasource.password=password spring.datasource.driver-class-name=com.mysql.jdbc.Driver # Druid连接池配置 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.initialSize=5 spring.datasource.minIdle=5 spring.datasource.maxActive=20 spring.datasource.testOnBorrow=true spring.datasource.validationQuery=SELECT 1# 配置Druid监控页面访问路径 spring.datasource.druid.stat-view-servlet.enabled=true spring.datasource.druid.stat-view-servlet.url-pattern=/druid/* ``` 您可以根据需要修改这些属性来满足您的实际需求。
完成以上步骤后，您的Spring Boot应用程序将使用Druid作为连接池。请确保您已经正确配置了数据库信息和Druid的相关属性。如果遇到任何问题，请及时提问并提供详细的错误信息，以便我们能够更好地帮助您解决问题。

北京阿里云ACE会长如果您想在Spring Boot 1.2.1中使用Druid连接池，可以添加druid-spring-boot-starter 1.1依赖。Druid-Spring-Boot-Starter是一个用于在Spring Boot应用程序中集成Druid连接池的官方Starter，它提供了自动配置和可选的监控功能，使得在应用程序中使用Druid变得更加简单和方便。

建议升级 Spring Boot 的版本至1.4.X以上版本（推荐使用1.5.X的当前稳定发行版本），Spring Boot 1.2.1确实太老了（2015.1发布），不支持使用ServletRegistrationBean的方式注册 Servlet，进而导致的该问题 。
