org.springframework.boot:spring-boot-starter-parent’ not found

简介: org.springframework.boot:spring-boot-starter-parent’ not found

一、问题

用 Spring Initializr创建的项目,然后点进pom.xml文件,有好几处变红,且报错,且DemoApplication报无法解析符号 ‘SpringBootApplication’

现在这个文件无法启动,且java无法创建类和接口,点击下方加载maven项目就好了

然后现在开始变红报错了,说无法解析符号 'SpringBootApplication'

以下是pom.xml开始报错

下面这个说找不到项目 'org.springframework.boot:spring-boot-starter-parent:3.1.2.RELEASE'

下面这个说找不到依赖项 'org.springframework.boot:spring-boot-starter-test:'  

二、解决

我把这个地方换成了2.1.8这个版本就好了

然后下方也不变红,报错了

然后点击maven刷新一下就好了

DemoApplication文件也不报错了

运行时报java: 错误: 无效的源发行版:16

然后把这个地方的17改成8

把下方的两个16都改成8,然后刷新一下maven就好了

这样就能运行成功了

解决Spring MVC中No converter found for return value of type异常
在Spring MVC开发中遇到`No converter found for return value of type`异常,通常是因缺少消息转换器、返回值类型不支持或转换器优先级配置错误。解决方案包括:1) 添加对应的消息转换器,如`MappingJackson2HttpMessageConverter`;2) 自定义消息转换器并实现`HttpMessageConverter`接口,设置优先级;3) 修改返回值类型为如`ResponseEntity`的合适类型。通过这些方法可确保返回值正确转换为响应内容。
