1.打开Java菜单File
2.打开设置Setting
3.点击Editor，找到File Encodings
4.将Project Encoding:选择GB2312，点击Apply，再点击OK，即可实现汉字正常输出！
输出：
这是由于文本编码类型不对导致的。
添加这几句话：
request.setCharacterEncoding(“GBK”); response.setContentType(“text/html;charSet=GBK”);
package demo;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class FirstServlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("GBK");
response.setContentType("text/html;charSet=GBK");
PrintWriter out =response.getWriter();
out.println("<html><body><font color=red size=20 >集美大学123</font></body></html>");
out.close();
}
}问题解决！！！
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
