（三）velocity--springmvc整合velocity

2016-04-05 11:28 399 查看

还是在springmvc工程上进行整合

添加jar包
右键pom.xml，菜单maven-->Add Dependency ，可以搜索添加velocity和velocity-tools两个包，另外还需要添加spring-context-support，不然会报错

添加vm文件

在WEB-INF下新建了一个views文件夹，里面加了两个文件，一个用来做模板，一个具体页面。

layout.vm

<head>
<title>Spring MVC and Velocity</title>
</head>
<body>
<h1>Spring MVC and Velocity</h1>
$screen_content
<hr />

</body>
</html>

hello.vm

welcome ${user}

配置

在servlet的配置文件中，加入velocity的相关配置，注意路径

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="suffix" value=".jsp" />
</bean>
</beans>

java文件

package com.lucky.study.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class MyController {

@RequestMapping(value = "/hello")
public ModelAndView hello() {
ModelAndView mv = new ModelAndView();
mv.addObject("user", "lucky");
//设置逻辑视图名，视图解析器会根据该名字解析到具体的视图页面
mv.setViewName("hello");
return mv;
}
}

运行后访问http://localhost:8080/velocity/hello.do
