The Druid connection pool is an open-source, high-performance connection pool used for managing database connections. Here is how to use the Druid connection pool:<\/p>\n

1. Include the Druid connection pool dependency: In the project’s build file, such as the Maven pom.xml file, add the dependency for the Druid connection pool.<\/p>\n

<dependency>\r\n    <groupId>com.alibaba<\/groupId>\r\n    <artifactId>druid<\/artifactId>\r\n    <version>1.1.10<\/version>\r\n<\/dependency>\r\n<\/code><\/pre>\n
2. Set up the Druid connection pool: Include the necessary parameters for the Druid connection pool in the project’s configuration file, such as application.properties or application.yml, including the database URL, username, and password.<\/p>\n
spring.datasource.url=jdbc:mysql:\/\/localhost:3306\/mydb\r\nspring.datasource.username=root\r\nspring.datasource.password=123456\r\nspring.datasource.driver-class-name=com.mysql.jdbc.Driver\r\n<\/code><\/pre>\n
3. Create a Druid connection pool object: Create a Druid connection pool object in the code and set the relevant parameters for the connection pool.<\/p>\n
import com.alibaba.druid.pool.DruidDataSource;\r\n\r\n...\r\n\r\nDruidDataSource dataSource = new DruidDataSource();\r\ndataSource.setUrl(\"jdbc:mysql:\/\/localhost:3306\/mydb\");\r\ndataSource.setUsername(\"root\");\r\ndataSource.setPassword(\"123456\");\r\n<\/code><\/pre>\n
4. Get Database Connection: Acquire a database connection from the Druid connection pool to carry out SQL operations.<\/p>\n
import java.sql.Connection;\r\nimport java.sql.SQLException;\r\n\r\n...\r\n\r\nConnection connection = dataSource.getConnection();\r\n<\/code><\/pre>\n
Perform SQL operations: use the obtained database connection to execute SQL operations, such as queries, inserts, updates, etc.<\/p>\n
import java.sql.Connection;\r\nimport java.sql.ResultSet;\r\nimport java.sql.SQLException;\r\nimport java.sql.Statement;\r\n\r\n...\r\n\r\nStatement statement = connection.createStatement();\r\nString sql = \"SELECT * FROM my_table\";\r\nResultSet resultSet = statement.executeQuery(sql);\r\n\/\/ \u5904\u7406\u67e5\u8be2\u7ed3\u679c...\r\n\r\n...\r\n\r\nresultSet.close();\r\nstatement.close();\r\n<\/code><\/pre>\n
6. Close the database connection: After using the database connection, it is necessary to manually close the connection in order to free up resources.<\/p>\n
connection.close();\r\n<\/code><\/pre>\n
By following the above steps, you can use the Druid connection pool to manage database connections, thus enhancing the performance and efficiency of database operations.<\/p>\n","protected":false},"excerpt":{"rendered":"
