即使在 build.gradle 中指定，也无法解析符号“EnableJpaRespositories”

【中文标题】即使在 build.gradle 中指定，也无法解析符号“EnableJpaRespositories”

【英文标题】：Cannot resolve symbol 'EnableJpaRespositories' even though specified in build.gradle

【发布时间】：2021-06-30 16:34:58

【问题描述】：

由于某种原因，我无法在我的项目中获取一个模块来检测它是否具有获取 @EnableJpaRepositories 的依赖项。尽管在我的 build.gradle 文件中指定了 implementation 'org.springframework.boot:spring-boot-starter-data-jpa'，但当我运行 gradle 尝试编译时，我收到以下错误：

./gradlew clean build 

> Task :rest:compileJava FAILED
/Users/pasdeignan/git/pasciifinance/rest/src/main/java/com/pasciitools/pasciifinance/rest/PasciifinanceApplication.java:22: error: cannot find symbol
@EnableJpaRespositories(basePackages="com.pasciitools.pasciifinance")
 ^
  symbol: class EnableJpaRespositories

FAILURE: Build failed with an exception.

背景

我正在构建一个多模块 Spring 项目，我试图将 JPA 片段存储在 common 模块中，并将 REST 服务存储在 rest 模块中。 rest 模块也是我的 SpringBootApplication 所在的地方。当我启动应用程序时，我收到以下错误：

***************************
APPLICATION FAILED TO START
***************************

Description:

Field accountRepo in com.pasciitools.pasciifinance.rest.PasciifinanceApplication required a bean of type 'com.pasciitools.pasciifinance.common.repositories.AccountRepository' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.pasciitools.pasciifinance.common.repositories.AccountRepository' in your configuration.

【参考方案1】：

您在@EnableJpaRespositories 中有错字。

您需要将其重命名为 @EnableJpaRepositories，正如您在问题中提出的那样。
