java.lang.NoClassDefFoundError: org/springframework/util/unit/DataSize 同时运行 spring boot 项目

Question

将 spring-boot 版本更改为 2.0.1.RELEASE 在运行 spring boot 项目时出现此错误。我只是从 2.0.3.RELEASE 更改版本

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.1.0.RELEASE</version>
    </dependency>

Answer 1

这个问题为我解决了，因为我的 POM.xml 错误地将 spring.version 在属性标记中。

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.1.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

<properties>
    <java.version>1.8</java.version>
    <kotlin.version>1.2.71</kotlin.version>
    <!-- <spring.version>5.0.6.RELEASE</spring.version> -->
</properties>
