异常Canonical-names-should-be-kebabcase-separated-lower

异常Canonical names should be kebab-case (‘-‘ separated), lowercase alpha-numeric characters and must start with a letter

Description:

Configuration property name 'projectUrl' is not valid:

    Invalid characters: 'U'
    Bean: projectUrlConfig
    Reason: Canonical names should be kebab-case ('-' separated), lowercase alpha-numeric characters and must start with a letter

Action:

Modify 'projectUrl' so that it conforms to the canonical names requirements.

Canonical names should be kebab-case (‘-‘ separated), lowercase alpha-numeric characters and must start with a letter

译：规范名称应为kebab大小写（“-”分隔），小写字母数字字符，并且必须以字母开头

Relaxed Binding

Spring Boot uses some relaxed rules for binding Environment properties to @ConfigurationProperties beans, so there does not need to be an exact match between the Environment property name and the bean property name. Common examples where this is useful include dash-separated environment properties (for example, context-path binds to contextPath), and capitalized environment properties (for example, PORT binds to port).

轻松绑定
Spring Boot使用一些宽松的规则将Environment属性绑定到@ConfigurationProperties bean，因此不需要在Environment属性名和bean属性名之间进行精确匹配。 这有用的常见示例包括破折号分隔的环境属性（例如，context-path绑定到contextPath）和大写环境属性（例如，PORT绑定到端口）。

projectUrl 应改为 project-url
