'spring.thymeleaf.servlet.content-type' 是一个未知属性

Question

我正在运行我的第一个 spring 项目，我正在使用 sts 作为 ide，我想将 Thymeleaf 用于页面模板，但是 th:href 链接不能作为链接，而是纯文本，但我可以'找不到我想要的页面，无法重定向到 thymeleaf 页面：

#==================================
# = JSP Configuration
#==================================
#spring.mvc.view.prefix: /WEB-INF/views/
#spring.mvc.view.suffix: .jsp
#
#==================================
# = Thymeleaf configurations
#==================================
#spring.thymeleaf.check-template-location=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.servlet.content-type=text/html
spring.thymeleaf.cache=false
spring.thymeleaf.encoding=UTF-8
server.servlet.context-path=/
#
#==================================
# = Datasource configuration
#==================================
spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
#spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.jpa.show-sql=true
logging.level.org.hibernate.SQL=debug
logging.level.org.hibernate.type.descriptor.sql=trace
logging.level.org.springframework.web=INFO
#spring.jpa.hibernate.ddl-auto=create
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost/siw
spring.datasource.username=postgres
spring.datasource.password=postgres

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
#
#==================================
# = Webserver configuration
#==================================
server.port= 8080 
#
#==================================
# = Misc configuration
#==================================
spring.messages.basename=messages/validation
#
#==================================
# = Security configuration
#==================================
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration
spring.security.user.name=paolo
spring.security.user.password=paolo

这是我用来通过 maven 查找和解决库依赖关系的 Pom：

如何修复它，我在 html 中使用 this 来指定使用 thymeleaf： xmlns:th="http://www.thymeleaf.org"

附：如果我使用 .../resource/templates 作为索引的位置，我找不到它；我需要把它放在.../resources/static

Answer 1

添加 th:ref 如下：

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body><div class="starter-template">
    <h1>Spring Boot Web Thymeleaf Example</h1>
    <h2>
        <span th:text="'Message: ' + ${message}"></span>
        <a th:href="@{${link}}">view</a>
       <!-- <span th:link="${link}" th:text="${link}"></span>-->
    </h2>
</div>
</body>
</html>

请参考here中的工作代码

关于您的其他问题，设置自定义模板位置，您需要像这样修改 application.properties 文件

spring.thymeleaf.check-template=true
spring.thymeleaf.check-template-location=true
spring.thymeleaf.enabled=true
spring.thymeleaf.prefix=classpath:/static/
spring.thymeleaf.suffix=.html
