SpringMVC整合Freemaker
首先需要导入相关jar包
其中: spring-context-support 包一定要导入 如果没有导入将出现以下错误
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer] for bean with name 'freemarkerConfig' defined in file [你的spring配置文件.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/ui/freemarker/FreeMarkerConfigurationFactory
Caused by: java.lang.NoClassDefFoundError: org/springframework/ui/freemarker/FreeMarkerConfigurationFactory
添加freemaker需要的jar包有
spring-context-support.jar
freemarker.jar
其他包则在新建SpringMVC项目的时候就加载进来了
完成jar包的添加,下面则需要在web.xml中添加相关配置
"1.0" encoding="UTF-8"?>
"2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
/index
contextConfigLocation
classpath:config/spring*.xml
org.springframework.web.context.ContextLoaderListener
springMVC
org.springframework.web.servlet.DispatcherServlet
1
springMVC
/
完成了web.xml的配置,下面则需要配置我们的 SpringMVC-servlet.xml
DispatcherServlet会根绝web.xml中配置的去找-servlet.xml的文件来加载spring的一些配置信息。我这里就应该取名叫springmvc-servlet.xml
"1.0" encoding="UTF-8"?>

如果是使用freemarker最为视图模板需要再spring的配置文件applicationContext.xml中加入以下配置 由于本人项目中Spring的配置文件叫 spring.xml 故我需要修改的是spring.xml
"1.0" encoding="UTF-8"?>

注意
在 spring.xml中配置 freemaker的 templateLoaderPath 目录 在springMVC-servlet.xml中则不需要在配置 仅需要在 spring.xml中配置即可.
如果出现以下错误,即有可能是2个都配置了地址或者是配置的目录错误
Could not resolve view with name ‘free’ in servlet with name ‘springMVC’
以上 我们就完成了freemaker和springMVC的整合.下面是我们的测试 controller
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class SpringMvcController {
@RequestMapping(value="/welcome",method=RequestMethod.GET)
public ModelAndView getFirstPage() {
//welcom就是视图的名称（welcome.ftl）
ModelAndView mv = new ModelAndView();
mv.setViewName("welcome");
mv.addObject("name", "this is freemaker test!!!");
return mv;
}
}
welcome.ftl

Hello ${name}
运行我们的项目:输入 htp://localhost:8080/你的项目名/welcome controller的地址在配置文件中配置过滤器
页面就会显示
Hello this is freemaker test!!!
