Use springboot:

Creating springboot application, select the desired scene;
springbooty default these scenes have been configured, only a small amount of configuration specified in the configuration file can be up and running;
Write your own business logic code;

1.springboot mapping rules for static resources

@ConfigurationProperties (prefix = "spring.resources", ignoreUnknownFileds = false )
 public  class ResourceProperties the implements The ResourceLoaderAware {
 // set and parameters related to static resources, such as cache time

1. All / Webjars / **, went classpath: / META-INF / resources / webjars / find resources;

webjars: jar package in the manner of the introduction of static resources;

http：//www.webjars.org/

localhost：8080/webjars/jquery/3.3.1/jquery.js

<!-- 引入jQuery-webjar -->
<dependency>
    <groupId>org.webjars</groupId>
    <artifactId>jquery</artifactId>
    <version>3.4.1</version>
</dependency>

2. "/ **" Any resource access current project (static resource file folder)

"the CLASSPATH: // META-INF / Resources /" ,
 "the CLASSPATH: // Resources /" ,
 "the CLASSPATH: // static /", 
"the CLASSPATH: // public /", 
"/": the current root path of the project

localhost: 8080 / xxx (static folder inside to find xxx)

3. Welcome Page: a static resource folders under index.html page all; by "/ *" Mapping;

localhost: 8080 / find index page

4. All ** / favicon.ico are looking at a static resource files;

2. The template engine

For example: jsp, Velocity, Freemaker, Thymeleaf.

springboot recommended Thymeleaf grammar simpler, more powerful;

1. The introduction of Thymeleaf

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

2.Thymeleaf use & grammar

Thymeleaf use the document: https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html

The default prefix = "classpath: / templates /" Default suffix = "html."

    @RequestMapping("/success")
    public String success(){
        return "success";
    }

Import Thymeleaf namespace 1.html page

<html lang="en"  xmlns:th="http://www.thymeleaf.org">

2. Use syntax Thymeleaf

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>成功！~ lol</h1>
<p th:text="${hello}"/>
</body>
</html>

3. syntax rules

　　　　1) th: text to change the text of the current element

　　　　　　　　th: attribute value to replace any of the native attributes html

　　　　2) expression (Thymeleaf Chapter IV document)

Simple expression:
- Variable expression:${...}
- Select variable expression:*{...}
- Message expression:#{...}
- Link URL expression:@{...}
- Fragment expression:~{...}
Writing
- Text Text: 'one text', 'Another one!', ...
- Digital text: 0, 34, 3.0, 12.3, ...
- Boolean text: true, false
- NULL text:null
- Text Tags: one, sometext, main, ...
Text manipulation:
- String concatenation:+
- Replace literal:|The name is ${name}|
Arithmetic:
- Binary operators: +, -, *, /, %
- Minus (unary):-
Boolean operations:
- Binary operators: and, or
- Boolean negation (unary): !, not
Compare and equality:
- Comparator: >, <, >=, <= ( gt, lt, ge, le)
- Equality Operator: ==, != ( eq, ne)
Conditional operator:
- If - Then:(if) ? (then)
- If - then - else:(if) ? (then) : (else)
- Default:(value) ?: (defaultvalue)
Special tokens:
- No - Action:_
