SpringMVC integrates velocity and springmvcvelocity

SpringMVC integrates velocity and springmvcvelocity
Preface

In the era where there is no artist, the corresponding template view development is inevitable. In the jsp era, we are also very comfortable to use, and everything is absolutely necessary. when the project is large, and the data model is complicated, jsp cannot be competent.

 

Development Environment

Idea2016, jdk1.8, and tomcat8.0.35

Spring 4.3.6, velocity1.6, and velocity-tools 2.0

 

SpringMVC integrates velocity

1. VelocityViewResolver.

<! -- VelocityViewResolver view configuration --> <! -- <Bean id = "viewResolver" class = "org. springframework. web. servlet. view. velocity. VelocityViewResolver"> --> <! -- <Property name = "suffix" value = ". vm"/> --> <! -- <Property name = "prefix" value = ""/> --> <! -- <Property name = "contentType" value = "text/html; charset = UTF-8"/> --> <! -- </Bean> -->

 

2. VelocityLayoutViewResolver. That is, you can customize the template layout. Compared with VelocityViewResolver, a layout. vm is added, which is configured in the WEB-INF/views/layout. vm.

<!--VelocityLayoutViewResolver-->    <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver">        <property name="suffix" value=".vm"/>        <property name="prefix" value=""/>        <property name="contentType" value="text/html;charset=UTF-8"/>        <property name="layoutUrl" value="layout/layout.vm"/>    </bean>

 

3, complete springmvc-servlet.xml

<Context: component-scan base-package = "com. autohome. controller"/> <! -- Annotation-driven --> <mvc: annotation-driven/> <! -- Velocity template configuration --> <bean id = "velocityConfig" class = "org. springframework. web. servlet. view. velocity. velocitycycler "> <property name =" resourceLoaderPath "value ="/WEB-INF/views/"/> <property name =" configLocation "value =" classpath: velocity. properties "/> <property name =" velocityProperties "> <props> <prop key =" input. UTF-8 </prop> <prop key = "output. encoding "> UTF-8 </prop> </props> </property> </ Bean> <! -- VelocityViewResolver view configuration --> <! -- <Bean id = "viewResolver" class = "org. springframework. web. servlet. view. velocity. VelocityViewResolver"> --> <! -- <Property name = "suffix" value = ". vm"/> --> <! -- <Property name = "prefix" value = ""/> --> <! -- <Property name = "contentType" value = "text/html; charset = UTF-8"/> --> <! -- </Bean> --> <! -- VelocityLayoutViewResolver --> <bean id = "viewResolver" class = "org. springframework. web. servlet. view. velocity. velocityLayoutViewResolver "> <property name =" suffix "value = ". vm "/> <property name =" prefix "value =" "/> <property name =" contentType "value =" text/html; charset = UTF-8 "/> <property name =" layoutUrl "value =" layout/layout. vm "/> </bean>

4. pom. xml

 <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.10</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>4.3.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.3.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context-support</artifactId>      <version>4.3.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.3.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.apache.velocity</groupId>      <artifactId>velocity</artifactId>      <version>1.6.2</version>    </dependency>    <dependency>      <groupId>org.apache.velocity</groupId>      <artifactId>velocity-tools</artifactId>      <version>2.0</version>    </dependency>  </dependencies>

The nested content of my layout. vm. view page is rendered in $ screen_content.

Index. vm
Layout. vm rendering result

 
Summary
1. pom does not automatically load the spring-context.jar package when downloading the spring-context-support.jar package and I cannot find the configLocation attribute when compiling the velocityconfig velocitypolicer class in springmvc-servlet. After adding the spring-context jar package, OK.
2. Now in velocity. the encoding format has been configured in the properties file, and the encoding method is still configured in velocityconfig. If not configured, a spring is thrown. vm-related exceptions. I don't know what this design is.
