SpringMVC整合Velocity要点

本文主要整理了SpringMVC整合Velocity的一些步骤和要点：

1、在pom.xml增加依赖的velocity包

<!-- spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>3.2.0.RELEASE</version>
</dependency>

<!--velocity-->
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-tools</artifactId>
<version>2.0</version>
</dependency>

2、在servlet-context.xml中的配置如下：

<!--配置spring的扫描器实现bean的自动载入-->
<context:component-scan base-package="com.xtt.webdemo.**.controller"/>

<!--属性占位器配置-->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<array>
<value>classpath:config.properties</value>
</array>
</property>
</bean>

<!--内容协商管理工厂Bean配置-->
<!--1、检查扩展名（如my.pdf）；2、检查Parameter（如my?format=pdf）；3、检查Accept Header-->
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="true" />
<property name="favorParameter" value="false" />
<property name="ignoreAcceptHeader" value="true" />
<!--扩展名到MIME的映射；favorPathExtension, favorParameter是true时起作用 -->
<property name="mediaTypes">
<props>
<prop key="json">application/json</prop>
<prop key="xml">application/xml</prop>
</props>
</property>
</bean>

<!--开启自动扫描驱动，并配置消息转换器-->
<mvc:annotation-driven
content-negotiation-manager="contentNegotiationManager">
<mvc:message-converters register-defaults="true">
<bean
class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<property name="features">
<value>WriteDateUseDateFormat</value>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>

<!-- velocityConfig -->
<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/velocity/"/>
<property name="velocityProperties">
<props>
<prop key="input.encoding">UTF-8</prop>
<prop key="output.encoding">UTF-8</prop>
</props>
</property>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver">
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".vm"/>
<property name="contentType" value="text/html;charset=utf-8"/>
<property name="layoutUrl" value="layout/layout.vm"/>
<property name="requestContextAttribute" value="ac"/>
<property name="order" value="1"/>
<property name="numberToolAttribute" value="numbertool"/>
<property name="dateToolAttribute" value="datetool"/>
</bean>

3、Controller编写

@Controller
public class IndexController {

@RequestMapping("/")
public String index(Model model) {
model.addAttribute("name", "tester");
return "index";
}

@RequestMapping("/error/404")
public String error404() {
return "404";
}

@RequestMapping("/error/500")
public String error500() {
return "500";
}

}
