自定义视图

package com.seven.views;

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.View;

//必须添加@Component，这样SpringMvc才会感知这个View
@Component
public class HelloView implements View {
    @Override
    public String getContentType() {
        return "text/html";
    }
    @Override
    public void render(Map<String, ?> map, HttpServletRequest httpServletRequest,
                       HttpServletResponse httpServletResponse) throws Exception {
        httpServletResponse.getWriter().print("hello view,time: "+new Date());
    }
}
