Servlet开发-day05

一、前台从后台取值?

servlet-<<jsp

方式一:

servlet:requegst.setAttribute("name","周杰");

jsp:request.getAttribute("name");

方式二:

servlet:request.setAttribute("name","周杰");

${name}

后台往前台写值?

servlet:out.write("网页面写值");

二、Web乱码问题解决方案?

1、jsp中设置contentType="text/html;charset=utf-8"

2、servlet中设置

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=utf-8");

3、数据库访问链接中设置

jdbc:mysql://localhost:3306/dataName?useUnicode=true&useCharacterEncoding=utf-8
