SpringMVC自定义视图-优快云博客

1、创建一个视图类实现spring的View接口，并且把视图类用@Component注解为sprinmvc组建（重要）

package com.hy.springmvc.views;

import java.util.Map;

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

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

@Component
public class HelloView implements View{

    @Override
    public String getContentType() {
        return "text/html";
    }

    @Override
    public void render(Map<String, ?> arg0, HttpServletRequest arg1,
            HttpServletResponse arg2) throws Exception {
        arg2.getWriter().println("this is a hello viesw");
    }

}

2、配置视图解析器BeanNameViewResolver,并且要指定解析器使用顺序Order,顺序先于常用解析器

<bean class="org.springframework.web.servlet.view.BeanNameViewResolver">
        <property name="order" value="100"></property>
    </bean>

3、测试代码：

@RequestMapping("/testView")
    public String testView() {
        System.out.println("testView");
        return "helloView";
    }

<a href="test/testView">testView</a>

这里会在页面上打印出helloview

注意：可以使用自定义视图处理多种视图，比如excel只需要继承抽像类AbstractXlsxView AbstractXlsView实现相应的方法buildExcelDocument
