背景
我有一个带有 spring data neo4j 的应用程序,我从 4.1.3 切换到 5.0.0。
我相信我已经进行了所有必要的更改来转换我的代码,但我仍然遇到错误。
我当前版本的 spring boot 是
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
<version>1.4.1.RELEASE</version>
</dependency>
问题
当我运行时:mvn spring-boot:run
在命令行中,
我收到一个错误:
***************************
APPLICATION FAILED TO START
***************************
Description:
Field actionRepository in myproject.service.ActionServiceImpl required a bean of type 'myproject.repository.ActionRepository' that could not be found.
Action:
Consider defining a bean of type 'myproject.repository.ActionRepository' in your configuration
我的 myproject.Application.java 目前是
@SpringBootApplication
@EnableTransactionManagement
@EnableSwagger2
@EntityScan(basePackages = "myproject.domain")
public class Application {
public static void main(String[] args) {
new SpringApplication(Application.class).run(args);
}
@Bean
public Docket Api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build()
.pathMapping("/")
.apiInfo(apiInfo());
}
private springfox.documentation.service.ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Service API")
}
}
这没有找到我的任何控制器,例如 myproject.controller.ActionController.java 包含
...
@RestController
@Api(value = "Action", description = "Actions Management API")
@RequestMapping(value = "/api/action")
public class ActionController extends Controller<Action> {
...
尝试#1
如果我将注释添加@ComponentScan({"myproject.request"})
到我的 Application 类中,错误就会消失,但 spring boot 无法加载任何控制器,因此我的 Swagger 显示没有 API 并且没有运行控制器。这不是解决方案。@SpringBootApplication
应该照顾这一切。
问题
如何重新配置 spring boot 以开始像在 spring data neo4j 版本 4.1.3 中那样工作?
更新 1 尝试 #2
我尝试将此注释添加到我的class Application
@EnableNeo4jRepositories("myproject.repository")
错误变成了不太干净的东西:
...

更新 2
为了尝试使用@EnableNeo4jRepositories("myproject.repository")
并绕过更新 1 中的错误,我尝试了:
mvn clean install spring-boot:repackage
它给了一个构建成功,但同样的错误仍然存在:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.4.1.RELEASE:run (default-cli) on project myproject: An exception occurred while running. null: InvocationTargetException: org.springframework.data.repository.config.RepositoryConfigurationSource.getAttribute(Ljava/lang/String;)Ljava/util/Optional; -
更新 3
我有新的注释并将我的 pom 从:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.12.0.RELEASE</version>
</dependency>
到
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>2.0.0.RELEASE</version>
</dependency>
现在mvn spring-boot:run
给出错误:
