Tomcat下配置MySQL数据库连接池_MySQL

Jun 01, 2016 pm 02:11 PM
name database connect Configuration

Tomcat


  1.在$CATALINA_HOME/conf/server.xml中添加配置信息,声明连接池的具体信息,添加内容如下:
  
  
  
  
  
  
  
  
  
  
  
  factory
  
  org.apache.commons.dbcp.BasicDataSourceFactory
  
  

  
  
  
  maxWait
  
  5000
  
  

  
  
  
  maxActive
  
  20
  
  

  
  
  
  username
  
  shopadm
  
  

  
  
  
  password
  
  123
  
  

  
  
  
  url
  
  jdbc:mysql://localhost/shopdb?useUnicode=true&charact-erEncoding=gb2312
  
  

  
  
  
  driverClassName
  
  com.mysql.jdbc.Driver
  
  

  
  
  
  maxIdle
  
  10
  
  

  
  

  
  2. 在$CATALINA_HOME/conf/web.xml的前添加如下信息:
  
  
  
  DB Connection
  
  jdbc/mysql
  
  javax.sql.DataSource
  
  Container
  
  

  
  其中中的参数名必须和server.xml中声明的连接名一样。
  
  3. 在$CATALINA_HOME/conf/catalina/localhost目录下找到需要进行数据库连接的当前程序的配置信息,比如这里是shopping.xml,在这个文件中添加如下信息:
  
  
  
  …
  
  
  
  …
  
  

  
  大功告成!
  
  在此基础上,参考Tomcat官方网站的用户手册,摸索出另外一种配置连接池的方法,这个方法不需要对server.xml进行修改,只要对需要使用到连接池的程序的配置文档进行修改就可以了。方法如下:
  
  1.$CATALINA_HOME/conf/catalina/localhost目录下找到需要数据库连接池的程序的配置文档,此处是shopping.xml。在 之间添加如下信息,声明一个数据库连接池:
  
  
  
  
  
  
  
  factory
  
  org.apache.commons.dbcp.BasicDataSourceFactory
  
  

  
  
  
  maxWait
  
  5000
  
  

  
  
  
  maxActive
  
  20
  
  

  
  
  
  password
  
  123
  
  

  
  
  
  url
  
  jdbc:mysql://localhost/shopdb?useUnicode=true&characterEncoding=gb2312
  
  

  
  
  
  driverClassName
  
  com.mysql.jdbc.Driver
  
  

  
  
  
  maxIdle
  
  10
  
  

  
  
  
  username
  
  shopadm
  
  

  
  

  
  这里的参数和上一种方法中添加到server.xml里的信息几乎是完全一样的。
  
  2.在对应程序的WEB-INF下建立一个web.xml文档,添加如下信息:
  
  
  
    
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
  
  http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
  
  version="2.4">
  
  
  
  DB Connection
  
  jdbc/mysql
  
  javax.sql.DataSource
  
  Container
  
  

  
  

  
  关键是斜体字的部分,指向前面声明的连接池。

iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos iOS 18 adds a new 'Recovered' album function to retrieve lost or damaged photos Jul 18, 2024 am 05:48 AM

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How does Hibernate implement polymorphic mapping? How does Hibernate implement polymorphic mapping? Apr 17, 2024 pm 12:09 PM

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

An in-depth analysis of how HTML reads the database An in-depth analysis of how HTML reads the database Apr 09, 2024 pm 12:36 PM

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.
