【小家Java】Servlet规范之---请求(request):Servlet中如何获取POST请求参数?(使用getParameter())
前言nrequest对象封装了来自客户端的所有请求信息。在HTTP协议中,客户端发给服务端的所有信息都是通过request对象的请求头和请求体来传送的。nServlet请求参数n<em>servlet</em>的请求参数作为客户端请求的一部分都是以字符串形式传给<em>servlet</em>容器。n参数以键值对方式存储,而且一个参数名可以对应多个参数值。ServletRequest接口的以下4个方法用于访问这些参数信息:nnget...

造成java.lang.NoClassDefFoundError错误的原因及解决办法
1、项目依赖的jar包未全部导入; 如:java.lang.NoClassDefFoundError: Could not initialize class com.esms.common.util.XmlUtil,当你去查这个类的时候发现这个类是存在,之所以抱着个错是 因为在这个类里面的方法引用了其他jar包中的类的方法,而这个被引用的这个jar包刚好缺失,所以抛出这个错。 解决办法:一层

[Servlet]HttpServletRequest的请求参数、标头、编码
1. HttpServletRequest的主要作用:n    1) 前面我们已经非常熟悉了,就是在服务器收到请求后创建该对象并将有关请求的所有信息都分解保存在HttpServlet的各个字段中供Servlet使用;n    2) 还有一个功能就是请求转发的功能,一个Servlet接收到Request对象后经过一分析发现可能需要另一个Servlet来处理(这是绝对允许的,这也是一种设计模式),

日常Exception(三):javax.servlet.http报红提示找不到
今天导入一个测试项目时,提示<em>javax</em>.<em>servlet</em>.http包找不到,很纳闷,按说这应该是jdk环境自带的包吧。后来去搜索查询了一番,其实也很好处理。rn解决办法:去到自己的tomcat安装路径,然后在tomcat的lib文件下找到一个<em>servlet</em>-api.jar包,将此包复制到自己的安装的jdk的jre\lib\ext目录下,关闭集成工具。重新打开就会发现,报错消失了。Is OK!
