自定义视图和视图解析器的步骤:
1).编写自定义的视图解析器，和视图实现类。
自定义的视图要实现View对象
public class MyView implements View{@Overridepublic String getContentType() {return "text/html";}@Overridepublic void render(Map<String, ?> model, HttpServletRequest request,HttpServletResponse response) throws Exception {List<String> novels = (List<String>) model.get("novel");response.setContentType("text/html;charset=utf-8");response.getWriter().write("哈哈<br/><h1>欢迎阅读四大名著</h1></br>");for(String n:novels){response.getWriter().write(n+"<br/>");}}}
自定义的视图解析器要实现ViewResolver对象，如果配置了多个视图解析器，可以通过实现Ordered接口，设置视图解析器的优先级。
public class MyViewResolver implements ViewResolver, Ordered{private Integer order = 0;@Overridepublic View resolveViewName(String viewName, Locale locale)throws Exception {if(viewName.startsWith("novel:")){return new MyView();}else{return null;}}@Overridepublic int getOrder() {return order;}public void setOrder(Integer order){this.order = order;}}
2).视图解析器放在ioc容器中。
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/pages/"></property><property name="suffix" value=".jsp"></property></bean><!-- order越小,优先级越大 --><bean class="com.view.MyViewResolver"><property name="order" value="0"></property></bean>
