Answer 1

如果您不想使用安全性，只需从您的 pom.xml 文件中删除或评论此依赖项：

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

when you use spring-security you have to pass the authentication before any action.

如果您想使用安全性，请将此安全配置添加到 application.properties 文件：

spring.security.user.name=custom-username
spring.security.user.password=custom-password
