在GAE上没有找到使用Spring3 MVC + Maven2的映射 [英] No mapping found using Spring3 MVC + Maven2 on GAE
问题描述
这是我的web.xml
< servlet>
< servlet-name>调度程序< / servlet-name>
< servlet-class> org.springframework.web.servlet.DispatcherServlet< / servlet-class>
< init-param>
< param-name> contextConfigLocation< / param-name>
< param-value>
/WEB-INF/spring/webmvc-config.xml
< / param-value>
< / init-param>
1< / load-on-startup>
< / servlet>
< servlet-mapping>
< servlet-name>调度程序< / servlet-name>
< url-pattern> / *< / url-pattern>
< / servlet-mapping>
这是我的SpringMVC配置文件
< context：annotation-config />
< context：component-scan base-package =com.mypackage/>
< mvc：annotation-driven />
< bean id =viewResolver
class =org.springframework.web.servlet.view.InternalResourceViewResolver
p：prefix =/ WEB-INF / jsp / view /
p：suffix =。jsp
p：viewClass =org.springframework.web.servlet.view.JstlView/>
这是我的控制器： 这是我的视图位于webapp / WEB- INF / jsp / view / hello.jsp
<$ p $ @Controller
@RequestMapping（value =/ hello）
public class HelloController {
@RequestMapping（method = RequestMethod.GET）
public String helloGet（ModelMap map）{
map.put（name，seb！）;
返回hello;

这是我的pom包含依赖到SpringMVC 3.0.3，servlet-api 2.5，jstl 1.2
我一直在收到
警告：找不到HTTP映射使用名为'dispatcher'的DispatcherServlet中的URI [/WEB-INF/jsp/view/hello.jsp]的请求
当我打localhost：8080 / hello时，我找不到原因。是由于GAE还是我在某些配置中丢失了任何内容？
更新：
如果我发送来自/ app / *到Spring Dispatcher，像这样改变我的web.xml：
< servlet-mapping>
< servlet-name>调度程序< / servlet-name>
< url-pattern> / app / *< / url-pattern>
< / servlet-mapping>`
它可以工作，但我只想使用着陆页并使用应用程序的根目录
我过去遇到过这个问题。如果我记得正确，它在部署时运行正常，但在开发服务器上失败。我的解决方案是将调度程序servlet映射到 / app / * ，而不是 / * 。
这会导致应用程序中所有URL路径中的 / app >。如果您想摆脱这种情况，请使用URL重写。
在 web.xml中：
< filter>
< filter-name> urlRewriteFilter< / filter-name>
< filter-class> org.tuckey.web.filters.urlrewrite.UrlRewriteFilter< / filter-class>
< / filter>
< filter-mapping>
< filter-name> urlRewriteFilter< / filter-name>
< url-pattern> / *< / url-pattern>
< / filter-mapping>
和 urlrewrite.xml ：
<？xml version =1.0encoding =utf-8？>
<！DOCTYPE urlrewrite PUBLIC - // tuckey.org//DTD UrlRewrite 3.0 // EN

I'm getting a weird issue trying to integrate Spring MVC and Maven in a Google AppEngine webapp.
This is my web.xml
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/webmvc-config.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
this is my SpringMVC config file
<context:annotation-config />
<context:component-scan base-package="com.mypackage" />
<mvc:annotation-driven/>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/view/"
p:suffix=".jsp"
p:viewClass="org.springframework.web.servlet.view.JstlView" />
this is my controller:
@Controller
@RequestMapping(value = "/hello")
public class HelloController {
@RequestMapping(method = RequestMethod.GET)
public String helloGet(ModelMap map) {
map.put("name", "seb!");
return "hello";
}
}
and this is my view located at webapp/WEB-INF/jsp/view/hello.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello Controller</title>
</head>
<body>
<h1>Hello ${name}!</h1>
</body>
</html>
and this is my pom contains dependencies to SpringMVC 3.0.3, servlet-api 2.5, jstl 1.2
I'm keeping getting
WARNING: No mapping found for HTTP request with URI [/WEB-INF/jsp/view/hello.jsp] in DispatcherServlet with name 'dispatcher'
when I hit localhost:8080/hello and I can't figure out why. Is it due to GAE or am I missing anything in some config?
Update: If I dispatch the URL coming from /app/* to Spring Dispatcher, changing my web.xml like this:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/app/*</url-pattern>
</servlet-mapping>`
it'll work, but I just want to use landing pages and use the root of the app
I've faced this issue in the past. If I recall correctly it worked properly when deployed, but failed on the development server. My solution was to map the dispatcher servlet to /app/* instead of /*.
That results /app in all the URL paths in your application. If you want to get rid of this, use URL rewriting.
In web.xml:
<filter>
<filter-name>urlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>urlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
And urlrewrite.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN"
"http://tuckey.org/res/dtds/urlrewrite3.0.dtd">
<urlrewrite default-match-type="wildcard">

<from>/**</from>
<to>/app/$1</to>
</rule>
<outbound-rule>
<from>/_ah/**</from>
<to>/_ah/$1</to>
</outbound-rule>
<outbound-rule>
<from>/app/**</from>
<to>/$1</to>
</outbound-rule>
</urlrewrite>
