tomcat下使用druid配置jnid数据源

tomcat下使用druid配置jnid数据源

• 导入jar包

   <!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
      <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.1.16</version>
      </dependency>

• 在tomcat的context.xml文件加入数据源配置

  <Resource
      name="jdbc/MysqlDataSource"
      factory="com.alibaba.druid.pool.DruidDataSourceFactory"
      auth="Container"
      type="javax.sql.DataSource"
      driverClassName="com.mysql.cj.jdbc.Driver"
      url="jdbc:mysql://localhost:3306/yl?characterEncoding=utf8&amp;serverTimezone=GMT%2B8"
      username="root"
      password="123456"
      maxActive="50"
      maxWait="10000"
      removeabandoned="true"
      removeabandonedtimeout="60"
      logabandoned="false"
      filters="stat"/>

• 获取连接

  protected void doGet(HttpServletRequest request, HttpServletResponse response)
              throws ServletException, IOException {
          try {
              //获取上下文对象
              Context context=new InitialContext();
              //获取数据源
              DataSource ds= (DataSource) context.lookup("java:comp/env/jdbc/MysqlDataSource");
              //获取Connection对象
              Connection connection=ds.getConnection();
  ​
              if(!connection.isClosed()){
                  System.out.println("连接成功");
  ​
              }
          } catch (NamingException e) {
              e.printStackTrace();
          } catch (SQLException e) {
              e.printStackTrace();
          }
      }
