spring

Bean Servlet Web Spring MVC

ModelAndView默认是使用转发(forward)方式来完成请求的结果画面，使用RedirectView的话，则会使用重新导向(Redirect)将请求重导到指定的结果位置。如：

java 代码HelloController

package org.beans;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.view.RedirectView;
public class HelloController implements Controller {
private String viewPage;
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
String user=request.getParameter("user");
return new ModelAndView(viewPage,"user",user);
}
public void setViewPage(String viewPage) {
this.viewPage = viewPage;
}
}

xml 代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean name="helloController" class="org.beans.HelloController"
abstract="false" singleton="true" lazy-init="default"
autowire="default" dependency-check="default">
<property name="viewPage">
<value>hello</value>
</property>
</bean>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
abstract="false" singleton="true" lazy-init="default"
autowire="default" dependency-check="default">
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
<bean id="urlHandleMapping"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"
abstract="false" singleton="true" lazy-init="default"
autowire="default" dependency-check="default">
<property name="interceptors">
<list>
<ref bean="loggingInterceptor"/>
</list>
</property>
<property name="mappings">
<props>
<prop key="/hello.do">helloController</prop>
</props>
</property>
</bean>
<bean id="loggingInterceptor" class="org.beans.LoggingInterceptor"
abstract="false" singleton="true" lazy-init="default"
autowire="default" dependency-check="default">
</bean></beans>

根据如上配置如果将java 代码HelloController改成如下：

java 代码

package org.beans;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.view.RedirectView;
public class HelloController implements Controller {
private String viewPage;
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
String user=request.getParameter("user");
return new ModelAndView(new RedirectView(viewPage),"user",user);
}
public void setViewPage(String viewPage) {
this.viewPage = viewPage;
}
}

则运行时出现错误。该怎么改呢？

主要有以下几种：
1、 return new ModelAndView(new RedirectView(this.getViewPage()));
2、return new ModelAndView("redirect:data.html");
3、Use the new redirect: syntax in my action-servlet.xml
<property name="successView"><value>redirect:/listAuctions.html</value></property>

return new ModelAndView("redirect:"+viewPage,"user",user);
