springmvc freemarker 之间的传参问题练习 出问题出现在配置文件上

1.pom.xml配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.zxx</groupId><artifactId>jettydemo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><properties><!-- spring版本号 --><spring.version>3.2.4.RELEASE</spring.version></properties><dependencies><!-- 添加Servlet --><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version><scope>provided</scope></dependency><!-- springmvc --><!-- spring核心包 --><!-- 1)spring核心依赖 --><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><!--2）spring dao层依赖 --><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><!-- 3)srping web依赖 --><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><!--4） 映射支持依赖 --><dependency><groupId>org.springframework</groupId><artifactId>spring-oxm</artifactId><version>${spring.version}</version></dependency><!-- JSTL标签类 --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency> <dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>3.2.4.RELEASE</version><type>jar</type></dependency> <dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>3.2.4.RELEASE</version><type>jar</type></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>3.2.4.RELEASE</version><type>jar</type></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>3.2.4.RELEASE</version><type>jar</type></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>3.2.4.RELEASE</version><type>jar</type></dependency><!-- FreeMarker --><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.19</version></dependency></dependencies><build><plugins><plugin><groupId>org.mortbay.jetty</groupId><artifactId>maven-jetty-plugin</artifactId><version>6.1.24</version><configuration><webDefaultXml>jetty.xml</webDefaultXml><contextPath>/</contextPath><scanIntervalSeconds>3</scanIntervalSeconds><connectors><connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"><port>8080</port><maxIdleTime>60000</maxIdleTime></connector></connectors><stopPort>9961</stopPort><stopKey>foo</stopKey><webAppConfig><contextPath>/</contextPath></webAppConfig></configuration></plugin></plugins></build></project>

2.web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:javaee="http://java.sun.com/xml/ns/javaee"xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><!-- 启动spring框架 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置启动spring框架时需要加载配置问价的路径 --><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext-*.xml</param-value></context-param><!-- springmvc --><servlet><servlet-name>suibian</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation，DispatcherServlet会默认加载[servlet-name]-servlet.xml文件。 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>suibian</servlet-name><url-pattern>*.htm</url-pattern></servlet-mapping><!-- <servlet><servlet-name>Hello</servlet-name><servlet-class>example.Hello</servlet-class></servlet><servlet-mapping><servlet-name>Hello</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping> --><welcome-file-list><welcome-file>index.html</welcome-file></welcome-file-list></web-app>

 

3.springmvc.xml配置

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd                http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd                http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd"><!-- 配置包扫描 --><context:component-scan base-package="com.zxx.controller" /><!-- 表示要注册两个对象DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter这两个对象可以帮助我们做好多的工作如：类型转换，静态资源放行，以及国际化等。。。 --><mvc:annotation-driven /><!-- <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".ftl" /> <property name="contentType" value="text/html;charset=UTF-8" /> <property name="requestContextAttribute" value="request" /> </bean> --><!-- 静态资源放行 --><mvc:resources location="/WEB-INF/img/" mapping="/img/**" /><!-- 配置视图解析器 --><!-- FreeMarker视图解析 如返回student。。在这里配置后缀名ftl和视图解析器。。 --><bean id="viewResolver"class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"><property name="viewClass"value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"></property><property name="prefix" value="/" /> <property name="suffix" value=".ftl" /><property name="contentType" value="text/html;charset=utf-8" /><property name="exposeRequestAttributes" value="true" /><property name="exposeSessionAttributes" value="true" /><property name="exposeSpringMacroHelpers" value="true" /></bean><!-- freemarker的配置 --><bean id="freemarkerConfig"class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath" value="/templates/" /><property name="defaultEncoding" value="utf-8" /><property name="freemarkerSettings"><props><prop key="template_update_delay">10</prop><prop key="locale">zh_CN</prop><prop key="datetime_format">yyyy-MM-dd</prop><prop key="date_format">yyyy-MM-dd</prop><prop key="number_format">#.##</prop></props></property></bean></beans>

 

4.controller编写

package com.zxx.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;@Controller()@RequestMapping("/login")public class LoginController { private static final String ps = "login"; @RequestMapping("/regist.htm") public ModelAndView loginlog() {  ModelAndView result = new ModelAndView(ps);  result.addObject("userList", "ppppppppppppppp");  result.addObject("bb", "999");  return result; }}

5.login.ftl书写

<html><head><meta http-equiv="Cache-Control" content="no-cache" /><meta http-equiv="content-type" content="text/html; charset=utf-8"><title>Hello</title></head><body><hr><h1>      ${bb}</h1></body></html>

运行 jetty:run

 

http://localhost:8080/login/regist.htm

 

会返回页面显示 999
