加载了ConfigurationProperties的嵌套映射的键以它们各自的索引为前缀。

Keys of nested map loaded with ConfigurationProperties are prefixed with their respective indexes

问题

使用Spring Boot，我试图使用注解 @ConfigurationProperties("oauth2.discovery") 加载配置。

一切工作正常，除了一个问题：嵌套映射的键不是根据配置文件内容加载的，而是以它们各自的索引作为前缀。

以下是用于加载配置的代码：

  1. @ConfigurationProperties("oauth2.discovery")
  2. public class DiscoveryConfigs {
  4.     private Map<String, DiscoveryConfigs.DiscoveryConfig> config;
  6.     public Map<String, DiscoveryConfigs.DiscoveryConfig> getConfig() {
  7.         return this.config;
  8.     }
  10.     public void setConfig(Map<String, DiscoveryConfigs.DiscoveryConfig> discovery) {
  11.         this.config = discovery;
  12.     }
  14.     public static class DiscoveryConfig {
  15.         private String name;
  16.         private Map<String, String> endpoints;
  18.         public String getName() {
  19.             return name;
  20.         }
  22.         public void setName(String name) {
  23.             this.name = name;
  24.         }
  26.         public Map<String, String> getEndpoints() {
  27.             return endpoints;
  28.         }
  30.         public void setEndpoints(Map<String, String> endpoints) {
  31.             this.endpoints = endpoints;
  32.         }
  33.     }
  34. }

这是我的 application.yml 配置文件：

  1. oauth2:
  2.   discovery:
  3.     config:
  4.       affiliation:
  5.         name: affiliation-service
  6.         endpoints:
  7.           public: /getPublic
  8.           forRoleA: /getForRoleA
  9.           forRoleB: /getForRoleB
  10.       blabla:
  11.         name: ...

使用 DiscoveryConfigs 加载 application.yml 后，我得到以下内容：

  1. (debugger view in IntelliJ)
  2. endpoints = {LinkedHashMap@10957}  size >= 3  
  3.    "0.public" -> "/getPublic"  
  4.    "1.forRoleA" -> "/getForRoleA"  
  5.    "2.forRoleB" -> "/getForRoleB"

其中，键的示例是 "0.public"，而不是 "public"。

所以我确定我漏掉了什么，但我无法弄清楚是什么...

With spring boot I'm trying to load configuration using the annotation @ConfigurationProperties("oauth2.discovery").

Everything works fine except the fact that keys of a nested map are not loaded with the configuration file content but instead they are prefixed with their respectiveindexes.

This is the code used to load the configuration :

  1. @ConfigurationProperties(&quot;oauth2.discovery&quot;)
  2. public class DiscoveryConfigs {
  4.     private Map&lt;String, DiscoveryConfigs.DiscoveryConfig&gt; config;
  6.     public Map&lt;String, DiscoveryConfigs.DiscoveryConfig&gt; getConfig() {
  7.         return this.config;
  8.     }
  10.     public void setConfig(Map&lt;String, DiscoveryConfigs.DiscoveryConfig&gt; discovery) {
  11.         this.config = discovery;
  12.     }
  14.     public static class DiscoveryConfig {
  15.         private String name;
  16.         private Map&lt;String, String&gt; endpoints;
  18.         public String getName() {
  19.             return name;
  20.         }
  22.         public void setName(String name) {
  23.             this.name = name;
  24.         }
  26.         public Map&lt;String, String&gt; getEndpoints() {
  27.             return endpoints;
  28.         }
  30.         public void setEndpoints(Map&lt;String, String&gt; endpoints) {
  31.             this.endpoints = endpoints;
  32.         }
  33.     }
  34. }

This is my application.yml

  1. oauth2:
  2.   discovery:
  3.     config:
  4.       affiliation:
  5.         name: affiliation-service
  6.         endpoints:
  7.           - public: /getPublic
  8.           - forRoleA: /getForRoleA
  9.           - forRoleB: /getForRoleB
  10.       blabla:
  11.         name: ...

And using DiscoveryConfigs to load the application.yml I got the following content:

> ( debugger view in IntellIj )
> endpoints = {LinkedHashMap@10957} size > = 3
> "0.public" -> "/getPublic"
> "1.forRoleA" -> "/getForRoleA"
> "2.forRoleB" -> "/getForRoleB"

Where keys are for example "0.public" instead of "public"

So I'm sure I missed something but I cannot figure what...

查看关于 Binding Maps 的说明在 spring.io 上。以下内容应该有效：

  1. oauth2:
  2.   discovery:
  3.     config:
  4.       affiliation:
  5.         name: affiliation-service
  6.         endpoints:
  7.           public: /getPublic
  8.           forRoleA: /getForRoleA
  9.           forRoleB: /getForRoleB
英文:

Checkout the description to Binding Maps on spring.io. The following should work:

  1. oauth2:
  2.   discovery:
  3.     config:
  4.       affiliation:
  5.         name: affiliation-service
  6.         endpoints:
  7.           public: /getPublic
  8.           forRoleA: /getForRoleA
  9.           forRoleB: /getForRoleB
