Java spring boot starter-thymeleaf - 无法找到请求目标的有效证书路径

Question

我是春季靴子的初学者。我正在尝试使用thymeleaf和html在localhost 8080上显示文本。尝试下载maven中的依赖项后：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
        <version>1.5.10.RELEASE</version>
    </dependency>

我收到这条消息：

无法读取org.springframework.boot的工件描述符：spring-boot-starter-thymeleaf：jar：1.5.10.RELEASE

在文件夹中：

“C：\ Users \ myUser \ .m2 \ repository \ org \ Spring Framework \ boot \ spring-boot-primer-thymeleaf \ 1.5.10.RELEASE”

有一个文件：

弹簧引导引物thymeleaf-1.5.10.RELEASE.pom.lastUpdated

内容：

NOTE: This is an Aether internal implementation file, its format can be changed without prior notice. #Sat Mar 03 08:48:15 CET 2018 @default-central- ttps://repo.maven.apache.org/maven2/.lastUpdated=1520063295482 https://repo.maven.apache.org/maven2/.error=Could not transfer artifact org.springframework.boot:spring-boot-starter-thymeleaf:pom:1.5.10.RELEASE from/to central (https://repo.maven.apache.org/maven2): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

其他依赖项，如spring-boot-starter-web或guava正常工作。 2.0.0.REALESE和其他人的问题是相同的。我会很感激任何建议。

和我的pom.xml

Answer 1

你的父母应该是：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.10.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

依赖应该是：

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

从依赖中删除<version>1.5.10.RELEASE</version>并检查。
