SpringMVC_04重定向和转发

在配置视图解析器的情况下

    class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          id="internalResourceViewResolver">
        
        
        
        
    


    class="controller.ControllerTest1"/>

转发正常写就行

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

@Controller
public class ModelTest1 {

    @RequestMapping("/m1/t1")
    public String test(HttpServletRequest request, HttpServletResponse response)
    {
        HttpSession session = request.getSession();
        System.out.println(session.getId());
        return "test";
    }
}

重定向只需要加上：redirect

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

@Controller
public class ModelTest1 {

    @RequestMapping("/m1/t1")
    public String test(HttpServletRequest request, HttpServletResponse response)
    {
        HttpSession session = request.getSession();
        System.out.println(session.getId());
        return "redirect:test";
    }
}
