我正在使用 Micronaut、Micronaut Data、JPA、Postgres 和 GraalVM 开发一个新示例，遵循 https://github.com/rmondejar/micronaut-postgres-example

此示例是使用具有以下功能的 Micronaut Launch 2.0.0.RC1 创建的：

[annotation-api, app-name, data, data-jpa, docker, file-watch, flyway, graalvm, gradle, hibernate-jpa, http-client, java, java-application, jdbc-hikari, logback, netty-server, postgres, readme, security-annotations, security-jwt, shade, spock, testcontainers, yaml]

没有本机图像，它可以完美运行，测试通过：

./gradlew test
(...)
24 passing (35.2s)
BUILD SUCCESSFUL in 43s
4 actionable tasks: 4 executed

生成本机映像并执行它看起来不错：

$ ./gradlew assemble
$ native-image --no-server -cp build/libs/mn-data-pg-*-all.jar
$ ./mn-data-pg

21:51:37.256 [main] INFO  com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Starting...
21:51:37.286 [main] INFO  com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Start completed.

21:51:37.349 [main] INFO  io.micronaut.runtime.Micronaut - Startup completed in 128ms. Server Running: http://localhost:8080

但是，一旦到达存储库，它总是会失败：

$ curl -d '{"username":"user1", "password":"password1"}' -H "Content-Type: application/json" -H "Authorization: Basic dXNlcjE6cGFzc3dvcmQx" -X POST http://127.0.0.1:8080/login

Caused by: io.micronaut.context.exceptions.NoSuchBeanException: No bean of type [io.micronaut.data.operations.PrimaryRepositoryOperations] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

转到本机时似乎是配置错误的问题，但是由于我遵循指南并使用生成的应用程序，因此不确定缺少什么。

从配置中删除 jpa package-to-scan 选项起到了作用：

jpa:
  default:
    packages-to-scan:
      - 'mn.data.pg.domain'
