注意：在SpringMVC配置文件中要能够扫描到视图所在的包（context:component-scan）。
自定义视图要实现view接口或继承AbstractView抽象类，并加入到IOC容器中（注意：定义的视图类要声明注解@Component）
package com.hello.view;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.View;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Date;
import java.util.Map;
@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(new Date());
}
}
进行springmvc配置文件的配置并设置视图优先级
<!--配置视图BeanNameViewResolver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 id="beanNameViewResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver">
<property name="order" value="100"></property>
</bean>注意：order的值越小优先级越高，当有多个视图解析器时，先通过优先级高的视图解析器来解析，如果不行，再由优先级低的视图解析器去解析。
在控制层添加目标方法
package com.helloworld;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("TestHelloWorldView")
public class TestHelloWorldView {
@RequestMapping("helloView")
public String testView(){
System.out.println("testView");
return "helloView";
}
}
index.jsp
