问题描述
当我尝试使用内存中的 h2 数据库和 Jpa 配置 micronaut-data 时,出现以下异常.
我一直在关注文档
I am getting this following exception when I try configuring micronaut-data with inmemory h2 database and Jpa.
I have been following the documentation
我使用 maven 作为构建工具从命令行创建了该项目.我有以下
I created the project from command line with maven as build tool. I have the following
<dependency>
<groupId>io.micronaut.configuration</groupId>
<artifactId>micronaut-jdbc-tomcat</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>io.micronaut.data</groupId>
<artifactId>micronaut-data-hibernate-jpa</artifactId>
<version>1.0.0.M3</version>
</dependency>
而且我还添加了这样的注释处理器
And Also I have added annotation processor like this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
......
<configuration>
...
<annotationProcessorPaths>
<path>
<groupId>io.micronaut</groupId>
<artifactId>micronaut-inject-java</artifactId>
<version>${micronaut.version}</version>
</path>
<path>
<groupId>io.micronaut</groupId>
<artifactId>micronaut-validation</artifactId>
<version>${micronaut.version}</version>
</path>
<path>
<groupId>io.micronaut.data</groupId>
<artifactId>micronaut-data-processor</artifactId>
<version>1.0.0.M3</version>
</path>
</annotationProcessorPaths>
</configuration>
.....
</plugin>
我的实体类和存储库类与指南中提到的完全一样.当我尝试使用存储库保存时,出现此异常
My Entity class and Repository class are exactly as mentioned in the guide. When I try to save using the repository, I get this exception
18:16:37.787 [pool-1-thread-3] ERROR i.m.h.s.netty.RoutingInBoundHandler - Unexpected error occurred: No backing RepositoryOperations configured for repository. Check your configuration and try again
io.micronaut.context.exceptions.ConfigurationException: No backing RepositoryOperations configured for repository. Check your configuration and try again
..............................
Caused by: io.micronaut.context.exceptions.NoSuchBeanException: No bean of type [io.micronaut.data.operations.RepositoryOperations] 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).
我已经研究过这个.这是完全不同的,它对我的问题没有帮助.
I have already looked into this. This is completely different and it doesn't help my issue.
有趣的是,如果我改变 micronaut 数据注释过程的顺序,或者我的意思是如果我这样放
Interestingly if I change the order of micronaut data annotation processsor I mean If I put like this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
......
<configuration>
...
<annotationProcessorPaths>
<path>
<groupId>io.micronaut</groupId>
<artifactId>micronaut-inject-java</artifactId>
<version>${micronaut.version}</version>
</path>
<path>
<groupId>io.micronaut</groupId>
<artifactId>micronaut-validation</artifactId>
<version>${micronaut.version}</version>
</path>
<path>
<groupId>io.micronaut.data</groupId>
<artifactId>micronaut-data-processor</artifactId>
<version>1.0.0.M3</version>
</path>
</annotationProcessorPaths>
</configuration>
.....
</plugin>
我得到了一个不同的例外.
I get a different exception.
Internal Server Error: All possible Introduction advise exhausted and no implementation found for method: Iterable saveAll(Iterable entities)
非常感谢任何指针.
推荐答案
文档不完整.做了一个拉取请求(https://github.com/micronaut-projects/micronaut-data/pull/197) 与文档更新.它已被接受.可以在此处
The documentation was incomplete. Did a pull request (https://github.com/micronaut-projects/micronaut-data/pull/197) with the documentation update. It has been accepted. The updated documentation can be found here
需要另一个依赖项才能工作
Need another dependency for this to work
<dependency>
<groupId>io.micronaut.data</groupId>
<artifactId>micronaut-data-hibernate-jpa</artifactId>
</dependency>
