3.springmvc.xml配置

<mvc:annotation-driven />

<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
