Grails REST API 使用域創建 class 未找到資源返回

Question

我正在嘗試創建一個 REST api 供用戶編輯。

我決定使用文檔中描述的方法：

https://docs.grails.org/3.3.11/guide/REST.html#domainResources （我使用的是舊版 grailsVersion=3.3.11）

所以我繼續，我像這樣創建了域 class（域 class 是由命令 grails s2-quickstart com.mastiko.auth 用戶角色創建的）

package com.mastiko.auth


import grails.rest.Resource

@Resource(uri = '/api/users', formats=['json'])
class User implements Serializable {

    private static final long serialVersionUID = 1

    String username
    String password
    String mems****ApiUser
    String mems****ApiPassword
    boolean enabled = true
    boolean accountExpired
    boolean accountLocked
    boolean passwordExpired

    Set<Role> getAuthorities() {
        (UserRole.findAllByUser(this) as List<UserRole>)*.role as Set<Role>
    }

    static constraints = {
        password nullable: false, blank: false, password: true
        username nullable: false, blank: false, unique: true
    }

    static mapping = {
        password column: '`password`'
    }
}

我的 application.groovy 看起來像這樣：

// Added by the Spring Security Core plugin:
grails.plugin.springsecurity.userLookup.userDomainClassName = 'com.mastiko.auth.User'
grails.plugin.springsecurity.userLookup.authorityJoinClassName = 'com.mastiko.auth.UserRole'
grails.plugin.springsecurity.authority.className = 'com.mastiko.auth.Role'
grails.plugin.springsecurity.controllerAnnotations.staticRules = [
    [pattern: '/',               access: ['permitAll']],
    [pattern: '/dbconsole/**',   access: ['permitAll']],
    [pattern: '/error',          access: ['permitAll']],
    [pattern: '/index',          access: ['permitAll']],
    [pattern: '/index.gsp',      access: ['permitAll']],
    [pattern: '/shutdown',       access: ['permitAll']],
    [pattern: '/assets/**',      access: ['permitAll']],
    [pattern: '/**/js/**',       access: ['permitAll']],
    [pattern: '/**/css/**',      access: ['permitAll']],
    [pattern: '/**/images/**',   access: ['permitAll']],
    [pattern: '/**/favicon.ico', access: ['permitAll']]
]

grails.plugin.springsecurity.filterChain.chainMap = [
    [pattern: '/assets/**',      filters: 'none'],
    [pattern: '/**/js/**',       filters: 'none'],
    [pattern: '/**/css/**',      filters: 'none'],
    [pattern: '/**/images/**',   filters: 'none'],
    [pattern: '/**/favicon.ico', filters: 'none'],
    [pattern: '/**',             filters: 'JOINED_FILTERS']
]

此外，我將此配置添加到 application.yml 中，因為沒有它我無法使 spring security rest api 插件工作

plugin:
  springsecurity:
    controllerAnnotations:
      chainMap:
        '/api/**': 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter'
        '/**': 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter'

我的 UrlMappings.groovy：

package mems****eprojects (censored)

class UrlMappings {

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

        "/"(controller: 'application', action:'index')
    }
}

現在，當我嘗試使用對 http://localhost:8080/api/users 的 POST 請求訪問我的 api 時，我總是得到 404 not found 響應：

{
    "timestamp": 1598893213831,
    "status": 404,
    "error": "Not Found",
    "message": "No message available",
    "path": "/api/users"
}

我嘗試了命令 grails url-mappings-report，得到了肯定的結果：

我是 grails 的新手，這是我的第一個應用程序。

如果缺少某些重要的代碼部分，我很抱歉，如果需要，我會發布。 你能幫我么？ 幾個小時以來，我一直在努力解決這個問題。

//編輯 1 我忘了添加我的 build.gradle

我添加了 spring-security-rest 插件，以便能夠使用 /api/login 端點從我的 vuejs 前端對自己進行身份驗證。 我檢索了令牌，然后我嘗試使用 header 中的令牌向 /api/users 端點發出請求。所以問題可能是由這個插件引起的

Answer 1

所以我能夠修復這個從 application.yml 中刪除的代碼

plugin:
  springsecurity:
    controllerAnnotations:
      chainMap:
        '/api/**': 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter'
        '/**': 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter'

並將下面的代碼添加到 application.groovy

grails.plugin.springsecurity.filterChain.chainMap = [
        //Stateless chain
        [ pattern: '/api/**', filters: 'JOINED_FILTERS,-anonymousAuthenticationFilter,-exceptionTranslationFilter,-authenticationProcessingFilter,-securityContextPersistenceFilter,-rememberMeAuthenticationFilter'],

        //Traditional chain
        //[ pattern: '/**', filters: 'JOINED_FILTERS,-restTokenValidationFilter,-restExceptionTranslationFilter']
]

我不太確定為什么我首先將 chainMap 放在 application.yml 中。
