Spring boot uses velocity, freemarker template to create HTML page to return to front end __html

In a few simple steps, implement the use of the velocity or freemarker template to construct the page in spring boot and return to the front end:


1. Introduce dependencies and create templates directory:
velocity:http://blog.csdn.net/clementad/article/details/51819647
freemarker:http://blog.csdn.net/clementad/article/details/51942629

2. Create template file:

Create two files, one corresponding to the normal page, file name:

Velocity:welcome.vm

FreeMarker:welcome.ftl

<! DOCTYPE html>
 

A page that corresponds to the error (automatically outputs this page when ULR input error, FileName: ERROR.VM or ERROR.FTL):


<! DOCTYPE html>
 


3, CONTROLLER code:

Package Com.xjj.web.controller;

Import Java.util.Map;

Import Org.springframework.stereotype.Controller;
Import org.springframework.web.bind.annotation.RequestMapping;

Import Com.xjj.util.XDateUtils;

@Controller
@RequestMapping ("/web") public
class Webcontroller {
	
	@RequestMapping ("/hi")
	Public String hi (map<string, object> model) {
		model.put ("Time", xdateutils.nowtostring ());
		Model.put ("message", "This is the content of the test ...) ");
		Model.put ("Tousername", "John");
		Model.put ("Fromusername", "Old Xu");
		return "Welcome"; Automatically look for resources/templates in the name of WELCOME.VM file as a template, assembled after the return
	}
}
 

 
4, testing: 

Enter Url:http://localhost:8082/web/hi in Browser

Results:

 

 
If you enter a URL that does not exist, such as Http://localhost:8082/web/hello, the result is as follows:
