**前言：**

本篇博客主要说明使用nacos做服务配置中心，分类配置的实现。

这里着重说明分类配置的扩展，并不会详细说明该分布式配置中心如何搭建，详细搭建过程可以参考我的另外一篇博客：

## 一。简述 ##

### 1.分类配置解决了什么问题？ ###

主要解决了多环境多项目管理的问题

### 2.nacos图形化管理界面 ###

配置管理：

命名空间：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 2]

### 3.Namespace+Group+Data ID三者的关系？ ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 3]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 4]  
通俗来说，可以将NameSpace类比成java项目中的项目名称，将Group类比成java项目中的包名称，而Data ID则可以类比成类名称。

## 二。DataID方案 ##

实现方式：指定spring.profile.active和配置文件的DataID来使不同环境下读取不同的配置

### 1.例子 ###

我们使用默认命名空间+默认分组+新建dev和test两个DataID

新建dev配置DataID:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 5]

新建test配置DataID:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 6]

### 2.服务配置文件配置 ###

两个配置读取application.yml配置文件配置一致，如下所示：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 7]

读取dev配置的bootstrap.yml配置文件如下：

![在这里插入图片描述][2020122411311165.png]

读取test配置的bootstrap.yml配置文件如下：

![在这里插入图片描述][20201224113116203.png]

### 3.测试 ###

**dev：**

![在这里插入图片描述][20201224113319325.png]

**test：**

![在这里插入图片描述][20201224113500617.png]

## 三。Group方案 ##

实现方式：通过group实现环境区分

### 1.例子 ###

新建两个分组DEV\_GROUP以及TEST\_GROUP，并放入同一个配置文件

**DEV\_GROUP：**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 8]

**TEST\_GROUP：**

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 9]

### 2.服务配置文件配置 ###

相比于DataID配置就加了一个group分组配置

**DEV\_GROUP分组：**

application.yml:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 10]

bootstrap.yml:

![在这里插入图片描述][20201224114537910.png]

**TEST\_GROUP分组：**

application.yml:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 11]

bootstrap.yml:

![在这里插入图片描述][2020122411461392.png]

### 3.测试 ###

**DEV\_GROUP分组：**

![在这里插入图片描述][20201224114637214.png]

**TEST\_GROUP分组：**

![在这里插入图片描述][20201224114641889.png]

## 四。NameSpace方案 ##

实现方式：通过namespace实现环境区分

### 1.例子 ###

新建两个命名空间dev和test

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 12]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 13]  
新建完成后，可以切换不同的命名空间：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 14]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 15]

在dev命名空间里面新建一个分组，并新建一个配置文件：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 16]

在test命名空间里面新建一个分组，并新建一个配置文件：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 17]

### 2.服务配置文件配置 ###

**dev命名空间：**

application.yml:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 18]

bootstrap.yml:

![在这里插入图片描述][20201224115044504.png]

**test命名空间：**

application.yml:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwOTQ0Nw_size_16_color_FFFFFF_t_70 19]

bootstrap.yml:

![在这里插入图片描述][20201224115049125.png]

### 3.测试 ###

**dev命名空间：**

![在这里插入图片描述][20201224115258738.png]

**test命名空间：**

![在这里插入图片描述][20201224115416462.png]
