This article mainly talks about "the method of SpringBoot Web development". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "the method of SpringBoot Web development".

Introduction 1.1.Introducing SpringBoot module

Before introducing the Web development module, let's summarize how to introduce a module in SpringBoot. We know that SpringBoot encapsulates functional modules as Starter:

1) create a SpringBoot application and select the module we need

2), SpringBoot has configured these scenarios by default, so you only need to specify a small number of configurations in the configuration file to run

3) write your own business code

What does SpringBoot configure for us in this scenario? Can you modify it? Which configurations can be modified? Can you expand it?

XxxxAutoConfiguration: help us automatically configure components in the container

XxxxProperties: configuration classes to encapsulate the contents of the configuration file

1.2 rules for mapping SpringBoot to static resources

1), all / webjars/**, go to classpath:/META-INF/resources/webjars/ under the resource jar package to find resources

Webjars: introducing static resources in the form of jar packages

Webjars website, go to the website

Org.webjars jquery 3.4.1

Example

If jquery is referenced, the path should be written as follows:

Localhost:8080/webjars/jquery/3.4.1/jquery.js

2), "/ *" to access any resources of the current project, go to (the folder of static resources) to find the mapping

"classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/" / ": the root path of the current project

Example

Localhost:8080/abc # look for abc in the static resource folder

3) Welcome page; all index.html pages under the static resource folder; mapped by "/ *"

Example: localhost:8080/ find index page

4) all * * / favicon.ico are found under static resource files

II. Introduction to template engine 2.1

Our common template engines are: JSP, Velocity, Freemarker, Thymeleaf

SpringBoot's official website recommends that we use Thymeleaf.

The schematic diagram is as follows:

2.2 introduction of thymeleaf 3.0.9.RELEASE 2.2.2 org.springframework.boot spring-boot-starter-thymeleaf2.3 Thymeleaf usage

We can see how Thymeleaf is used and the configuration information from the ThymeleafProperties class:

@ ConfigurationProperties (prefix = "spring.thymeleaf") public class ThymeleafProperties {private static final Charset DEFAULT_ENCODING = StandardCharsets.UTF_8; public static final String DEFAULT_PREFIX = "classpath:/templates/"; public static final String DEFAULT_SUFFIX = ".html"; / /. Omit.}

As long as we put the HTML page on classpath:/templates/,thymeleaf, it will render automatically.

1. Import the namespace of thymeleaf

2. Use thymeleaf grammar

At this point, I believe that you have a deeper understanding of the "method of SpringBoot Web development", might as well come to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
