Spring 3.1.1基于java的FreeMarkerConfigurer配置问题

我使用Spring 3.1.1和Freemarker。我成功地使用了新的spring 3.1的基于java的配置的新概念之后。现在我尝试使用Freemarker。不过，我得到的例外：Spring 3.1.1基于java的FreeMarkerConfigurer配置问题

javax.servlet.ServletException：无法与名称与名称的servlet“/欢迎 'appServlet' org.springframework.web.servlet.DispatcherServlet.render解决视图（DispatcherServlet.java:1139） org.springframework.web.servlet.DispatcherServlet.doDispatch（DispatcherServlet.java:927） org.springframework.web.servlet.DispatcherServlet.doService（DispatcherServlet.java:827） org.springframework。 web.servlet.FrameworkServlet.processRequest（FrameworkServlet.java:882） org.springframework.web.servlet.FrameworkServlet.doGet（FrameworkServlet.java:778） javax.servlet.http.HttpServlet.service（HttpServlet.java:621） javax.servlet.http.HttpServlet.service（HttpServlet.java:722）

这里是WebConfig：

package com.springway.config; 

@Configuration 
@ComponentScan("com.springway") 
@EnableWebMvc 
public class WebConfig extends WebMvcConfigurerAdapter { 

    @Inject 
    private Environment environment; 

    public void addResourceHandlers(ResourceHandlerRegistry registry) { 
     registry.addResourceHandler("/resources/**").addResourceLocations("/resources/"); 
    } 

    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { 
     converters.add(new MappingJacksonHttpMessageConverter()); 
    } 

    @Bean 
    public ViewResolver viewResolver() { 
     UrlBasedViewResolver viewResolver = new UrlBasedViewResolver(); 
     viewResolver.setViewClass(FreeMarkerView.class); 
     return viewResolver; 
    } 

    @Bean 
    public FreeMarkerConfigurer freeMarkerConfigurer() { 

     FreeMarkerConfigurer configurer = new FreeMarkerConfigurer(); 
     configurer.setTemplateLoaderPath(
       "/WEB-INF/freemarker.xml"); 

     return configurer; 
    }

freemarker.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://www.springframework.org/schema/beans"

    <!-- freemarker config --> 
    <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

     </property> 
     <property name="freemarkerVariables"> 
     <map> 
      <entry key="xml_escape" value-ref="fmXmlEscape"/> 
     </map> 
     </property> 
    </bean> 

    <bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/> 


    <!-- 

     View resolvers can also be configured with ResourceBundles or XML files. If you need 
     different view resolving based on Locale, you have to use the resource bundle resolver. 

    --> 
    <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> 
     <property name="cache" value="true"/> 
     <property name="prefix" value=""/> 
     <property name="suffix" value=".ftl"/> 
    </bean> 

</beans>

控制器：

@RequestMapping(value="/", method=RequestMethod.GET) 
public ModelAndView home(Principal user) { 

return new ModelAndView("/welcome.ftl"); 
}

我已为我的答案。我希望它能帮助你。 – Echo 2012-04-29 20:58:45

我正在努力解决与您相同的问题。我试图打开“org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer”的日志级别“DEBUG”。我发现了以下消息：

java.io.FileNotFoundException: ServletContext resource [/WEB-INF/freemarker/] cannot be resolved to URL because it does not exist at org.springframework.web.context.support.ServletContextResource.getURL(ServletContextResource.java:154) ~[spring-web-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.web.context.support.ServletContextResource.getFile(ServletContextResource.java:169) ~[spring-web-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.ui.freemarker.FreeMarkerConfigurationFactory.getTemplateLoaderForPath(FreeMarkerConfigurationFactory.java:351) [spring-context-support-3.1.1.RELEASE.jar:3.1.1.RELEASE] at org.springframework.ui.freemarker.FreeMarkerConfigurationFactory.createConfiguration(FreeMarkerConfigurationFactory.java:304) [spring-context-support-3.1.1.RELEASE.jar:3.1.1.RELEASE] .....

而且从码头有线日志：

WARN org.eclipse.jetty.util.log - /freemarker/

我不知道是什么回事！因此，我用另一个名称替换了“templateLoaderPath”的值，如“/ WEB-INF/tmpl-freemarker /”，然后一切都可行！

接下来，我试着用ServerContext.getResource()来测试“/WEB-INF/freemarker/html.ftl”。下面是结果：

Resource under /WEB-INF/freemarker/: null

我的测试代码：

@Inject 
private ServletContext servletContext; 

try { 
    logger.info("Resource under /WEB-INF/freemarker/: {}", servletContext.getResource("/WEB-INF/freemarker/html.ftl")); 
} catch(Exception e) { 
    logger.info("Exception while getResource", e); 
}

看来ServletContext不能找出 “/ WEB-INF/freemarker的/” 正确要么在资源。但是我不确定Spring的ServletContext的对象与Java Servlet的正常环境中的对象是否一样。

我使用Maven的FreeMarker 2.3.19，Springframework 3.1.1.RELEASE和jetty-maven-plugin 7.4.5.v20110725。

你可能做错了进口

import org.springframework.web.portlet.ModelAndView;

，而不是做这个

import org.springframework.web.servlet.ModelAndView;
