3. 配置Druid连接SQL Server的步骤

步骤 操作
1 导入SQL Server JDBC驱动包
2 配置Druid数据源
3 使用Druid连接SQL Server数据库

4. 操作步骤及代码

步骤一:导入SQL Server JDBC驱动包

在项目中导入SQL Server JDBC驱动包,例如sqljdbc4.jar

步骤二:配置Druid数据源

application.properties文件中配置Druid数据源:

# 配置Druid数据源
spring.datasource.url=jdbc:sqlserver://yourSqlServerAddress:1433;DatabaseName=yourDatabaseName
spring.datasource.username=yourUsername
spring.datasource.password=yourPassword
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
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.testWhileIdle=true
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1

步骤三:使用Druid连接SQL Server数据库

在代码中使用Druid数据源连接SQL Server数据库:

// 获取Druid数据源
@Autowired
private DataSource dataSource;

// 使用Druid连接SQL Server数据库
Connection conn = dataSource.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM yourTableName");

while(rs.next()){
    // 处理查询结果
}

// 关闭连接
rs.close();
stmt.close();
conn.close();

希望以上步骤和代码能够帮助你成功配置Druid连接SQL Server数据库。祝你早日成为一名优秀的开发者!
