熟悉JSP服务器

本“JSP由浅入深” 系列教程是面向中级和高级用户的,它需要HTML和Java的基础。你应该会将HTML网页连接到一起,并且会利用Java来进行编程。如果你还没有这个基础,建议你还是先打好基础为好。这个系列教程将通过编制简单的例子到复杂的例子来教会你JSP。本系列教程是采用循序渐进的方法来进行阐述的,即由浅入深。为了使你能够获得最大的进步,建议你再学习的过程中将所有的例子自己进行调试。开始的例子可能会很简单,所以开始的时候你要特别耐心,不要认为太简单而跳过。如果你仔细地调试例子,那么你就会很快地熟悉JSP的本质方法。

好吧,开始我们的第一个教程:熟悉JSP服务器。

如果你没有一个JSP网络服务器,那么你在开始教程之前还是先下载它吧。以下的几个服务器可以免费下载或者进行开发:

Blazix (1.5 Megabytes, JSP, Servlets and EJBs)
来自www.blazix.com/blazix.html

ServletExec (3.8 Megabytes, JSP and Servlets)
来自www.unifyeware.com/servletExec/

JRun (11 Megabytes, JSP, Servlets and EJBs)
来自www.jrun.com/

WebLogic(44 Megabytes, JSP, Servlets and EJBs)
来自www.beasys.com/

WebSphere (105 Megabytes, JSP, Servlets and EJBs)
来自www-4.ibm.com/sofeware/webservers/

如果你还没有服务器,那我建议你下载Blazix,因为它包含了标签库(可以用于以后关于标签库的教程)。Blazix同样也是很小的并且它可以很容易地下载,而且可以运行于所有的操作系统,包括处于主流的Windows98。还有一个优点,就是它的安装的速度更块。

为了真正学习JSP,最重要的是,你要在一个真实的服务器来调试教程的例子。最好的方法是通过自己的实践来学习JSP的技巧。如果你现在还没有服务器,那就先下载一个安装它就行了。

装上网络服务器以后,你应该学会以下关于网络服务器的的一些知识:应该在哪里放置文件?怎样访问来自浏览器的文件(是以http:开头的,而不是file:开头)?

你首先要创建以下的简单文件,比如:





Hello, world





怎样放置文件并在浏览器(以http://)中浏览它,这个步骤对应不同的网络服务器是不同的,所以你需要参看网络服务器的文档并找出答案。

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
