错误:缺少工件组织.thymelaf:thymeleaf-spring5:jar:3.0.3.RELEASE

Question

我正在用thymelaf构建一个spring-boot项目，并在pom.xml文件的第三行(xsi:schemaLocation….(中得到以下错误

缺少工件组织。thymelaf:thymeleaf-spring5:jar:3.0.3.RELEASE

我的pom.xml文件：

如果我从依赖项中删除版本属性

<thymeleaf.version>3.0.3.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.2.1</thymeleaf-layout-dialect.version>

运行时出现以下错误：

org.springframework.beans.factory.BeanCreationException：创建类路径资源[org/springframeter/boot/autoconfig/web/servlet/WebMvcAutoConfiguration$WebMvcAutoConfigurationAdapter.class]中定义的名称为"viewResolver"的bean时出错

试试这个：

这里我删除了这些行

<thymeleaf.version>3.0.3.RELEASE</thymeleaf.version>
<thymeleaf-layout-dialect.version>2.2.1</thymeleaf-layout-dialect.version>

并替换了这种依赖

<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>

带有

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
<version>2.5.2</version>
</dependency>
