来自HttpServletResponse的java Spring MVC相对重定向

Question

鉴于这种相对重定向到另一个控制器的方法：

@Controller
@RequestMapping("/someController")
public class MyController {
    @RequestMapping("/redirme")
    public String processForm(ModelMap model) {            
        return "redirect:/someController/somePage";
    }
}

如果我在一个拦截器中，我如何模拟相同的相对重定向

public class MyInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception
    {
        response.sendRedirect("/someController/somePage");
        return false;
    }
}

现在有了拦截器，我将在应用程序中结束。com/someController/somePage时，我真的想在应用程序中。com/deployment/someController/somePage。肯定有“春天”的解决方案吗

Answer 1

在参考了redirect documentation、查看了UrlBasedViewResolver的源代码以及gotuskar的评论之后，我觉得自己很傻，因为我不知道这会起作用，也不知道有一个解决方案：

public class MyInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception
    {
        StringBuilder targetUrl = new StringBuilder();
        if (this.redirectURL.startsWith("/")) {
            // Do not apply context path to relative URLs.
            targetUrl.append(request.getContextPath());
        }
        targetUrl.append(this.redirectURL);

        if(logger.isDebugEnabled()) {
            logger.debug("Redirecting to: " + targetUrl.toString());
        }

        response.sendRedirect(targetUrl.toString());
        return false;
    }
}

Answer 2

将我的评论转换为回答-

尝试使用response.sendRedirect(request.getContextPath() + uri);
