一个简单的servlet,用来测试GET,POST请求
package xyz.liut;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/servlet") // 请求接口
public class Test extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// 设置编码和content-type
response.setCharacterEncoding("utf-8");
response.setContentType("application/json");
// response.setContentType("application/json;charset=utf-8");
// 获取参数
String param0 = request.getParameter("param0");
String param1 = request.getParameter("param1");
// 输出
PrintWriter pw = response.getWriter();
pw.println("req by " + request.getMethod());
pw.println("req_ContentType " + request.getContentType());
pw.println("resp_ContentType " + response.getContentType());
pw.println();
pw.println("param0 = " + param0);
pw.println("param1 = " + param1);
pw.close();
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
