Thymeleaf 模板引擎在springboot中的使用1.介绍 Thymeleaf是Spring boot推荐使用的

1.介绍

Thymeleaf是Spring boot推荐使用的模版引擎

2.SpringBoot中引入

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

3.配置

1.默认配置

默认前缀 classpath:/templates/
默认后缀 .html

更多如下：

@ConfigurationProperties(
    prefix = "spring.thymeleaf"
)
public class ThymeleafProperties {
    private static final Charset DEFAULT_ENCODING;
    public static final String DEFAULT_PREFIX = "classpath:/templates/";
    public static final String DEFAULT_SUFFIX = ".html";
    private boolean checkTemplate = true;
    private boolean checkTemplateLocation = true;
    private String prefix = "classpath:/templates/";
    private String suffix = ".html";
    private String mode = "HTML";
    private Charset encoding;
    private boolean cache;
    private Integer templateResolverOrder;
    private String[] viewNames;
    private String[] excludedViewNames;
    private boolean enableSpringElCompiler;
    private boolean renderHiddenMarkersBeforeCheckboxes;
    private boolean enabled;
    private final Servlet servlet;
    private final Reactive reactive;
    
    public ThymeleafProperties() {
        this.encoding = DEFAULT_ENCODING;
        this.cache = true;
        this.renderHiddenMarkersBeforeCheckboxes = false;
        this.enabled = true;
        this.servlet = new Servlet();
        this.reactive = new Reactive();
    }

2.修改配置

在application.properties文件中已spring.thymeleaf前缀进行修改

# ThymeleafProperties
spring.thymeleaf.cache=false
spring.thymeleaf.encoding=UTF-8

4.使用

1.在页面中加入命名空间

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

2.按照语法修改html页面

1.标准表达式

${...} 变量表达式
@{...} 链接URL表达式
*{...} 选择变量表达式
#{...} 消息表达式
~{...} 片段表达式

2.替换页面内容

1.替换文字

th:text 替换文本
th:utext 支持html的文本替换。

<div th:text="${usernameMsg}">
   该账号不存在!
</div>
