This article focuses on "how to use Thymeleaf string objects". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor learn how to use Thymeleaf string objects.

Thymeleaf mainly uses the org.thymeleaf.expression.Strings class to handle strings, and the # strings object in the template to handle strings.

Development environment: IntelliJ IDEA 2019.2.2

Spring Boot version: 2.1.8

Create a new Spring Boot project named demo.

1 、 pom.xml

Join Thymeleaf dependency

Org.springframework.boot spring-boot-starter-thymeleaf

2 、 src/main/resources/application.yml

Set the template cache to false so that you can see the results immediately after modifying the html page and refreshing the browser.

Spring: thymeleaf: cache: false

3 、 src/main/java/com/example/demo/TestController.java

Package com.example.demo;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class TestController {@ RequestMapping ("/") public String test () {return "test";}}

4 、 src/main/resources/templates/test.html

Call the toString method of the parameter returns the length of the string to determine whether the string is empty or null is empty or null sets the default value to determine whether to include (case-sensitive) to determine whether to include (ignore case) to determine whether the beginning and end contain (case-sensitive) to get the index of the string (if there is no return-1) to specify the start and end indexes, and to intercept the string (if the index exceeds the string length Throws an exception) specifies that the string is intercepted from behind a string (returns an empty string if it is not included) specifies that the string is intercepted in front of a string (or an empty string is returned if it is not included) that the replacement string is converted to uppercase to lowercase conversion to lowercase the first letter of each word is converted to uppercase according to the delimiter. The mother is converted to an uppercase string by appending the string after the string (unlimited number of parameters) splicing the string after the second parameter If the parameter is null, the first parameter is used instead of deleting the blank string to intercept the specified length (minimum 3), followed by. Generates random alphanumeric numbers with a specified number of digits, ranging from uppercase letters to 0-9 digits. Call the escapeHtml4Xml method of the HtmlEscape class to encode the parameters

Concatenate the string after the second parameter. If the parameter is null, delete the blank hello string with the first parameter instead of hello*world and intercept the specified length (minimum 3), followed by... hello.... Generate a specified number of random alphanumeric characters, with a range of uppercase letters plus 0-9 digits. PBAT calls the escapeHtml4Xml method of the HtmlEscape class to encode the parameters hello so far. I believe you have a deeper understanding of "how to use the Thymeleaf string object". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
