JavaEE——SpringMVC（4）--自定义视图

首先配置BeanNameViewResolver

<!--配置BeanNameViewResolver视图解析器  使用视图的名字来解析视图-->
    <!-- 通过 order 属性来定义视图解析器的优先级, order 值越小优先级越高 -->
    <bean class="org.springframework.web.servlet.view.BeanNameViewResolver">
        <property name="order" value="100"></property>
    </bean>

　　

写一个实现了View接口的类  implements View

然后实现其抽象

方法：

package springmvc.views;

import org.springframework.web.servlet.View;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Date;
import java.util.Map;

public class HelloView implements View {
    @Override
    public String getContentType() {
        return "test/html";
    }

    @Override
    public void render(Map<String, ?> map, HttpServletRequest httpServletRequest,
                       HttpServletResponse httpServletResponse) throws Exception {

        httpServletResponse.getWriter().print("hello view, time: " + new Date());
    }
}

　　记得要在类前面加上@Component 

然后写调用方法  注意返回值是类名小写

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

　　超链接调用

<a href="HelloWorld/testView">Test View</a>
