Grails 4.1.1 Data Service無法注入Command Object: NoSuchBeanDefinitionException

[英]Grails 4.1.1 Data Service cannot be injected into Command Object: NoSuchBeanDefinitionException

問題描述

我有一個簡單的控制器/命令/數據服務設計：

@Secured("ROLE_BACKEND")
class CommunityController {
    static namespace = "api"

    static allowedMethods = [index: "GET"]

    def index(GetCommunitiesRequest request) {
        respond request.execute(params).get()
    }
}

@CompileStatic
class GetCommunitiesRequest implements Validateable {
    @Autowired
    CommunityService communityService

    GetCommunitiesRequest() {
        println "Hello"
    }

    Boolean withPartners = false
    Integer max

    Try<List<Map>> execute(Map params) {
        def r = Try.of {
            params.max = Math.min(max ?: 10, 100)
            communityService.list(params)
        }.map {communities->
            communities.collect {it.asMap(withPartners)}
        }
    }
}

@Service(Community)
interface CommunityService {

    abstract Community get(Serializable id)

    abstract List<Community> list(Map args)

    abstract Long count()

    abstract void delete(Serializable id)

    abstract Community save(Community community)

}

這是 UrlMappings 文件（以防萬一有命名空間控制器的鏈接）：

class UrlMappings {

    static mappings = {
        group "/api", {
            delete "/$controller/$id(.$format)?"(action:"delete", namespace:'api')
            get "/$controller(.$format)?"(action:"index", namespace:'api')
            get "/$controller/$id(.$format)?"(action:"show", namespace:'api')
            post "/$controller(.$format)?"(action:"save", namespace:'api')
            put "/$controller/$id(.$format)?"(action:"update", namespace:'api')
            patch "/$controller/$id(.$format)?"(action:"patch", namespace:'api')

            "/"(controller: 'application', action: 'index', namespace:"api")
            "500"(view: '/error')
            "404"(view: '/notFound')
        }

        "/$controller/$action?/$id?(.$format)?"{
            constraints {
                // apply constraints here
            }
        }

        "/"(controller: 'application', action:'index')
        "500"(view: '/error')
        "404"(view: '/notFound')
    }
}

此代碼的大部分基於 grails 在我的域 class 上使用 generate-all 時生成的代碼。顯然，添加的皺紋是命令（和 Try monad，但這應該是無關緊要的）。

當我執行此端點時，出現以下異常：

關於如何開始調查此問題的任何想法？ 顯然，如果您直接知道答案，歡迎您:)。

我試過的

  • 我已經嘗試逐步調試命令 object 的實例化（這就是為什么我添加了一個空的構造函數，以便能夠設置斷點），但是我正在為 ApplicationContext 層的復雜性而苦苦掙扎，我覺得我不太了解為什么這個服務 bean 沒有被注入。
    問題發生在 grails.artefact.Controller#initializeCommandObject

  • 我安裝了 grails 控制台插件，應用程序啟動后，我嘗試使用ctx.communityService訪問 communityService bean，並得到一個屬性 bean 作為響應： com.example.pr.domain.$CommunityServiceImplementation@5deeeb12

  • 在同一個 grails 控制台中，當我嘗試執行以下代碼時：

def controller = ctx.getBean("com.example.pr.http.api.CommunityController")
  
controller.initializeCommandObject(com.examplep.pr.request.GetCommunitiesRequest, "request")

我得到同樣的例外

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.example.pr.request.GetCommunitiesRequest': Unsatisfied dependency expressed through field 'communityService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.pr.data.service.CommunityService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

任何幫助表示贊賞。

試圖刪除命令 object 中的@Autowired注釋。它仍然失敗，但有一個稍微不同的異常（ ConversionNotSupportedException ）：

事實證明，我錯誤地在另一個 package 中創建了我的CommunityService數據服務的副本。Grails 在嘗試實例化命令 object 時感到困惑，當時它試圖自動裝配它並且不知何故沒有報告有 2 個候選人（？）。

我有兩個相同的服務副本：

  • com.example.pr.domain.CommunityService （由generate-all生成）
  • com.example.pr.service.data.CommunityService （嘗試重新打包為更符合邏輯的 package 結構，而不是將服務放在domain包中）
