SpringMvc-自定义视图

1.创建视图：

注意：创建视图的时候需要实现View接口的俩个方法

package com.atguigu.springmvc.views;

import java.util.Date;
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, ?> map, HttpServletRequest req, HttpServletResponse res) throws Exception {
        res.getWriter().print("hellow,view Time"+new Date());
    }

}

2.创建视图解析器

在配置视图解析器时候需要指定value的值，指定了value的值后springMvc能够首先匹配自定义的视图解析器，匹配不上在去调用默认的视图解析器

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