我在邮递员中收到 404 错误，没有任何异常线索......即使在控制台中也没有异常线索......

我在邮递员那里得到了一些东西，比如......

{ "时间戳": "2019-12-14T09:37:06.245+0000", “状态”：404， “错误”：“未找到”， "message": "没有可用的消息", “路径”：“/origin-group/origin/group/artistInfo” }

这是我点击的网址 localhost:8080/origin-group/origin/group/artistInfo

更新

调试我的代码后，我更改了几行代码.... 现在我遇到了一个错误，例如....

【问题讨论】：

  • origin-group路径在哪里配置？
  • 这些详细信息可在 applications.properties 中找到
  • 响应状态为 404，这意味着您正在请求错误的资源。检查您的网址。你可以在这里找到更多en.wikipedia.org/wiki/List_of_HTTP_status_codes
  • @SivaReddy 您的包名在配置时不正确
  • 您发送数组，但您的代码需要单个项目：@PostMapping("/artistInfo") public void createHero(@Valid @RequestBody Artist artistInfo) {

标签： java json spring spring-boot spring-mvc


【解决方案1】：

在 ArtistRepository 中使用“@repository”注解

【讨论】：

    【解决方案2】：

    您的弹簧配置不正确。看看你的配置：

     @EnableJpaRepositories("my.package.base.*")

    这里的包名是错误的。用正确的名称替换所有包，例如：

    @EnableJpaRepositories("com.origin.starter")

    【讨论】：

    • @SivaReddy，检查您的网址。您的请求路径错误。
