【问题描述】：

我是 Spring Boot 新手，但遇到错误。我尝试了很多方法来解决这个问题，但我失败了。 java.base/jdk.internal.reflect.NativeMethod AccessorImpl.invoke0(Native Method) ~[na:na]

我的 pom.xml 和 application.properties 和错误信息如下。

我删除了不必要的属性。如果你需要我也可以写这些。

APPLICATION.PROPERTIES


spring.datasource.url = jdbc:postgresql://localhost:5432/postgres
spring.datasource.username = postgres
spring.datasource.password = postgres
spring.datasource.driver-class-name = org.postgresql.Driver

spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false
spring.jpa.generate-ddl=true

如果可以，请帮助我。

【问题讨论】：

显然错误消息：Caused by: java.lang.ClassNotFoundException: org.springframework.boot.bind.RelaxedPropertyResolver。使用的是什么版本的 Spring Boot？仅在 Spring Boot 2 中找到的类
我希望这会有所帮助。 4.0.0org.springframework.bootspring-boot-starter-parent2.3.3.RELEASE

标签： java spring postgresql spring-boot

【解决方案1】：

您似乎混合了您的春季版本。就像这里所说： org/springframework/boot/bind/RelaxedPropertyResolver not found.

您是否在 POM 文件中确定了 spring boot starter 父级。这里有更多细节： https://docs.spring.io/spring-boot/docs/2.3.3.RELEASE/maven-plugin/reference/html/#getting-started

此站点对于初始化新的 Spring 项目也很有用： https://start.spring.io/
