HomeBackend DevelopmentXML/RSS TutorialDetailed introduction to the role of XML in JAVA projects

In java projects, xml files are generally used to store some configuration information
General programming, most of them are used to store configuration information. Take JDBC as an example, you can Write the database connection string to xml. If you want to modify the data source, you only need to change the xml. There is no need to recompile the java file. Moreover, these configuration information are put together, and other people can It is much more convenient when reading the code you wrote. In addition to configuration information, you can also write some corresponding relationships in xml in
framework, which is actually a kind of configuration information. Take struts as an example, The xml configuration is the relationship between the page URL and the background java class (action). When configuring and modifying, you only need to change an xml file. There is no need to search for the java code one by one
After the java project is completed, each module should be independent, and the relationship between modules can be maintained using xml. Spring is such a framework

A good project needs to be well scalable If all logical relationships and configuration information are written into the code, the scalability of the program will be poor. In order to solve this problem, xml can schedule the entire project (spring)

There is also the use of xml as data storage, but it is rarely used. Most of it is used to store configuration information

Different xmls play different roles: for example, configuration files## in web projects #Plays the role of configuring paths and redirecting requests. The hibernate configuration file plays the role of configuring the connection database and related attributes and mapping the entity class and the relational database . The spring configuration file plays the role of Configure the instantiation of javabeans and the role of the integration framework. There are also some xml files that store some data for the program to read. In fact, in the final analysis, the configuration file is equivalent to a small database for storing data. Using dom4j and other jar packages that read and write configuration files can read the configuration files, and it can also be used as a cross-language medium! !

XML外部实体注入漏洞的示例分析XML外部实体注入漏洞的示例分析May 11, 2023 pm 04:55 PM

一、XML外部实体注入XML外部实体注入漏洞也就是我们常说的XXE漏洞。XML作为一种使用较为广泛的数据传输格式,很多应用程序都包含有处理xml数据的代码,默认情况下,许多过时的或配置不当的XML处理器都会对外部实体进行引用。如果攻击者可以上传XML文档或者在XML文档中添加恶意内容,通过易受攻击的代码、依赖项或集成,就能够攻击包含缺陷的XML处理器。XXE漏洞的出现和开发语言无关,只要是应用程序中对xml数据做了解析,而这些数据又受用户控制,那么应用程序都可能受到XXE攻击。本篇文章以java

Python中怎么对XML文件的编码进行转换Python中怎么对XML文件的编码进行转换May 21, 2023 pm 12:22 PM

1.在Python中XML文件的编码问题1.Python使用的xml.etree.ElementTree库只支持解析和生成标准的UTF-8格式的编码2.常见GBK或GB2312等中文编码的XML文件,用以在老旧系统中保证XML对中文字符的记录能力3.XML文件开头有标识头,标识头指定了程序处理XML时应该使用的编码4.要修改编码,不仅要修改文件整体的编码,还要将标识头中encoding部分的值修改2.处理PythonXML文件的思路1.读取&解码:使用二进制模式读取XML文件,将文件变为
