Druid应用

使用

1、配置pom.xml

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid</artifactId>
  <version>1.0.9</version>
</dependency>

2、配置文件
允许properties格式配置，db.properties

username=root
password=3145tj
driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/study?useSSL=false&serverTimezone=UTC&characterEncoding=utf8

3、代码

Properties properties = new Properties();
InputStream inputStream = DruidTest.class.getClassLoader().getResourceAsStream("db.properties");
properties.load(inputStream);
DataSource dataSource = DruidDataSourceFactory.createDataSource(properties);
Connection connection = dataSource.getConnection();

spring整合

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> 
     <!-- 基本属性 url、user、password -->
     <property name="driverClassName" value="${jdbc.driver}" />
     <property name="url" value="${jdbc_url}" />
     <property name="username" value="${jdbc_user}" />
     <property name="password" value="${jdbc_password}" />
</bean>
