# 多租户模式配置改进说明
|
||||
|
||||
## 问题背景
|
||||
|
||||
用户在 issue #3835 中提出了一个架构设计问题:
|
||||
|
||||
> 基础 Wx 实现类中已经有 configMap 了,可以用 configMap 来存储不同的小程序配置。不同的配置,都是复用同一个 http 客户端。为什么在各个 spring-boot-starter 中又单独创建类来存储不同的配置?从 spring 的配置来看,http 客户端只有一个,不同小程序配置可以实现多租户,所以似乎没必要单独再建新类存放?重复创建,增加了 http 客户端的成本?直接使用 Wx 实现类中已经有 configMap 不是更好吗?
|
||||
|
||||
## 解决方案
|
||||
|
||||
从 4.8.0 版本开始,我们为多租户 Spring Boot Starter 提供了**两种实现模式**供用户选择:
|
||||
|
||||
### 1. 隔离模式(ISOLATED,默认)
|
||||
|
||||
**实现方式**:为每个租户创建独立的 WxService 实例,每个实例拥有独立的 HTTP 客户端。
|
||||
|
||||
**优点**:
|
||||
- ✅ 线程安全,无需担心并发问题
|
||||
- ✅ 不依赖 ThreadLocal,适合异步/响应式编程
|
||||
- ✅ 租户间完全隔离,互不影响
|
||||
|
||||
**缺点**:
|
||||
- ❌ 每个租户创建独立的 HTTP 客户端,资源占用较多
|
||||
- ❌ 适合租户数量不多的场景(建议 < 50 个租户)
|
||||
|
||||
**代码实现**:`WxMaMultiServicesImpl`, `WxMpMultiServicesImpl` 等
|
||||
|
||||
### 2. 共享模式(SHARED,新增)
|
||||
|
||||
**实现方式**:使用单个 WxService 实例管理所有租户配置,通过 ThreadLocal 切换租户,所有租户共享同一个 HTTP 客户端。
|
||||
|
||||
**优点**:
|
||||
- ✅ 共享 HTTP 客户端,大幅节省资源
|
||||
- ✅ 适合租户数量较多的场景(支持 100+ 租户)
|
||||
- ✅ 内存占用更小
|
||||
|
||||
**缺点**:
|
||||
- ❌ 依赖 ThreadLocal 切换配置,在异步场景需要特别注意
|
||||
- ❌ 需要注意线程上下文传递
|
||||
|
||||
**代码实现**:`WxMaMultiServicesSharedImpl`, `WxMpMultiServicesSharedImpl` 等
|
||||
|
||||
## 使用方式
|
||||
|
||||
### 配置示例
|
||||
|
||||
```yaml
|
||||
wx:
|
||||
ma: # 或 mp, cp, channel
|
||||
apps:
|
||||
tenant1:
|
||||
app-id: wxd898fcb01713c555
|
||||
app-secret: 47a2422a5d04a27e2b3ed1f1f0b0dbad
|
||||
tenant2:
|
||||
app-id: wx1234567890abcdef
|
||||
app-secret: 1234567890abcdef1234567890abcdef
|
||||
|
||||
config-storage:
|
||||
type: memory
|
||||
http-client-type: http_client
|
||||
# 多租户模式配置(新增)
|
||||
multi-tenant-mode: shared # isolated(默认)或 shared
|
||||
```
|
||||
|
||||
### 代码使用(两种模式代码完全相同)
|
||||
|
||||
```java
|
||||
@RestController
|
||||
public class WxController {
|
||||
@Autowired
|
||||
private WxMaMultiServices wxMaMultiServices; // 或 WxMpMultiServices
|
||||
|
||||
@GetMapping("/api/{tenantId}")
|
||||
public String handle(@PathVariable String tenantId) {
|
||||
WxMaService wxService = wxMaMultiServices.getWxMaService(tenantId);
|
||||
// 使用 wxService 调用微信 API
|
||||
return wxService.getAccessToken();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能对比
|
||||
|
||||
以 100 个租户为例:
|
||||
|
||||
| 指标 | 隔离模式 | 共享模式 |
|
||||
|------|---------|---------|
|
||||
| HTTP 客户端数量 | 100 个 | 1 个 |
|
||||
| 内存占用(估算) | ~500MB | ~50MB |
|
||||
| 线程安全 | ✅ 完全安全 | ⚠️ 需注意异步场景 |
|
||||
| 性能 | 略高(无 ThreadLocal 切换) | 略低(有 ThreadLocal 切换) |
|
||||
| 适用场景 | 中小规模 | 大规模 |
|
||||
|
||||
## 支持的模块
|
||||
|
||||
目前已实现共享模式支持的模块:
|
||||
|
||||
- ✅ **小程序(MiniApp)**:`wx-java-miniapp-multi-spring-boot-starter`
|
||||
- ✅ **公众号(MP)**:`wx-java-mp-multi-spring-boot-starter`
|
||||
|
||||
后续版本将支持:
|
||||
- ⏳ 企业微信(CP)
|
||||
- ⏳ 视频号(Channel)
|
||||
- ⏳ 企业微信第三方应用(CP-TP)
|
||||
|
||||
## 迁移指南
|
||||
|
||||
### 从旧版本升级
|
||||
|
||||
升级到 4.8.0+ 后:
|
||||
|
||||
1. **默认行为不变**:如果不配置 `multi-tenant-mode`,将继续使用隔离模式(与旧版本行为一致)
|
||||
2. **向后兼容**:所有现有代码无需修改
|
||||
3. **可选升级**:如需节省资源,可配置 `multi-tenant-mode: shared` 启用共享模式
|
||||
|
||||
### 选择建议
|
||||
|
||||
**使用隔离模式(ISOLATED)的场景**:
|
||||
- 租户数量较少(< 50 个)
|
||||
- 使用异步编程、响应式编程
|
||||
- 对线程安全有严格要求
|
||||
- 对资源占用不敏感
|
||||
|
||||
**使用共享模式(SHARED)的场景**:
|
||||
- 租户数量较多(> 50 个)
|
||||
- 同步编程场景
|
||||
- 对资源占用敏感
|
||||
- 可以接受 ThreadLocal 的约束
|
||||
|
||||
## 注意事项
|
||||
|
||||
### 共享模式下的异步编程
|
||||
|
||||
如果使用共享模式,在异步编程时需要注意 ThreadLocal 的传递:
|
||||
|
||||
```java
|
||||
// ❌ 错误:异步线程无法获取到正确的配置
|
||||
CompletableFuture.runAsync(() -> {
|
||||
wxService.getUserService().getUserInfo(...); // 可能使用错误的租户配置
|
||||
});
|
||||
|
||||
// ✅ 正确:在主线程获取必要信息,传递给异步线程
|
||||
String appId = wxService.getWxMaConfig().getAppid();
|
||||
CompletableFuture.runAsync(() -> {
|
||||
log.info("AppId: {}", appId); // 使用已获取的配置信息
|
||||
});
|
||||
```
|
||||

# 微信小程序多租户配置说明
|
||||
|
||||
## 多租户模式对比
|
||||
|
||||
从 4.8.0 版本开始,wx-java-miniapp-multi-spring-boot-starter 支持两种多租户实现模式:
|
||||
|
||||
### 1. 隔离模式(ISOLATED,默认)
|
||||
|
||||
每个租户创建独立的 `WxMaService` 实例,各自拥有独立的 HTTP 客户端。
|
||||
|
||||
**优点:**
|
||||
- 线程安全,无需担心并发问题
|
||||
- 不依赖 ThreadLocal,适合异步/响应式编程
|
||||
- 租户间完全隔离,互不影响
|
||||
|
||||
**缺点:**
|
||||
- 每个租户创建独立的 HTTP 客户端,资源占用较多
|
||||
- 适合租户数量不多的场景(建议 < 50 个租户)
|
||||
|
||||
**适用场景:**
|
||||
- SaaS 应用,租户数量较少
|
||||
- 异步编程、响应式编程场景
|
||||
- 对线程安全有严格要求
|
||||
|
||||
### 2. 共享模式(SHARED)
|
||||
|
||||
使用单个 `WxMaService` 实例管理所有租户配置,所有租户共享同一个 HTTP 客户端。
|
||||
|
||||
**优点:**
|
||||
- 共享 HTTP 客户端,大幅节省资源
|
||||
- 适合租户数量较多的场景(支持 100+ 租户)
|
||||
- 内存占用更小
|
||||
|
||||
**缺点:**
|
||||
- 依赖 ThreadLocal 切换配置,在异步场景需要特别注意
|
||||
- 需要注意线程上下文传递
|
||||
|
||||
**适用场景:**
|
||||
- 租户数量较多(> 50 个)
|
||||
- 同步编程场景
|
||||
- 对资源占用有严格要求
|
||||
|
||||
## 配置方式
|
||||
|
||||
### 使用隔离模式(默认)
|
||||
|
||||
```yaml
|
||||
wx:
|
||||
ma:
|
||||
# 多租户配置
|
||||
apps:
|
||||
tenant1:
|
||||
app-id: wxd898fcb01713c555
|
||||
app-secret: 47a2422a5d04a27e2b3ed1f1f0b0dbad
|
||||
token: aBcDeFg123456
|
||||
aes-key: abcdefgh123456abcdefgh123456abc
|
||||
tenant2:
|
||||
app-id: wx1234567890abcdef
|
||||
app-secret: 1234567890abcdef1234567890abcdef
|
||||
token: token123
|
||||
aes-key: aeskey123aeskey123aeskey123aes
|
||||
|
||||
# 配置存储(可选)
|
||||
config-storage:
|
||||
type: memory # memory, jedis, redisson, redis_template
|
||||
http-client-type: http_client # http_client, ok_http, jodd_http
|
||||
# multi-tenant-mode: isolated # 默认值,可以不配置
|
||||
```
|
||||
|
||||
### 使用共享模式
|
||||
|
||||
```yaml
|
||||
wx:
|
||||
ma:
|
||||
# 多租户配置
|
||||
apps:
|
||||
tenant1:
|
||||
app-id: wxd898fcb01713c555
|
||||
app-secret: 47a2422a5d04a27e2b3ed1f1f0b0dbad
|
||||
tenant2:
|
||||
app-id: wx1234567890abcdef
|
||||
app-secret: 1234567890abcdef1234567890abcdef
|
||||
# ... 可配置更多租户
|
||||
|
||||
# 配置存储
|
||||
config-storage:
|
||||
type: memory
|
||||
http-client-type: http_client
|
||||
multi-tenant-mode: shared # 启用共享模式
|
||||
```
|
||||
|
||||
## 代码使用
|
||||
|
||||
两种模式下的代码使用方式**完全相同**:
|
||||
|
||||
```java
|
||||
@RestController
|
||||
@RequestMapping("/ma")
|
||||
public class MiniAppController {
|
||||
|
||||
@Autowired
|
||||
private WxMaMultiServices wxMaMultiServices;
|
||||
|
||||
@GetMapping("/userInfo/{tenantId}")
|
||||
public String getUserInfo(@PathVariable String tenantId, @RequestParam String code) {
|
||||
// 获取指定租户的 WxMaService
|
||||
WxMaService wxMaService = wxMaMultiServices.getWxMaService(tenantId);
|
||||
|
||||
try {
|
||||
WxMaJscode2SessionResult session = wxMaService.jsCode2SessionInfo(code);
|
||||
return "OpenId: " + session.getOpenid();
|
||||
} catch (WxErrorException e) {
|
||||
return "错误: " + e.getMessage();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 性能对比
|
||||
|
||||
以 100 个租户为例:
|
||||
|
||||
| 指标 | 隔离模式 | 共享模式 |
|
||||
|------|---------|---------|
|
||||
| HTTP 客户端数量 | 100 个 | 1 个 |
|
||||
| 内存占用(估算) | ~500MB | ~50MB |
|
||||
| 线程安全 | ✅ 完全安全 | ⚠️ 需注意异步场景 |
|
||||
| 性能 | 略高(无 ThreadLocal 切换) | 略低(有 ThreadLocal 切换) |
|
||||
| 适用场景 | 中小规模 | 大规模 |
|
||||
|
||||
## 注意事项
|
||||
|
||||
### 共享模式下的异步编程
|
||||
|
||||
如果使用共享模式,在异步编程时需要注意 ThreadLocal 的传递:
|
||||
|
||||
```java
|
||||
@Service
|
||||
public class MiniAppService {
|
||||
|
||||
@Autowired
|
||||
private WxMaMultiServices wxMaMultiServices;
|
||||
|
||||
public void asyncOperation(String tenantId) {
|
||||
WxMaService wxMaService = wxMaMultiServices.getWxMaService(tenantId);
|
||||
|
||||
// ❌ 错误:异步线程无法获取到正确的配置
|
||||
CompletableFuture.runAsync(() -> {
|
||||
// 这里 wxMaService.getWxMaConfig() 可能返回错误的配置
|
||||
wxMaService.getUserService().getUserInfo(...);
|
||||
});
|
||||
|
||||
// ✅ 正确:在主线程获取配置,传递给异步线程
|
||||
WxMaConfig config = wxMaService.getWxMaConfig();
|
||||
String appId = config.getAppid();
|
||||
CompletableFuture.runAsync(() -> {
|
||||
// 使用已获取的配置信息
|
||||
log.info("AppId: {}", appId);
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 动态添加/删除租户
|
||||
|
||||
两种模式都支持运行时动态添加或删除租户配置。
|
||||
|
||||
## 迁移指南
|
||||
|
||||
如果您正在使用旧版本,升级到 4.8.0+ 后:
|
||||
|
||||
1. **默认行为不变**:如果不配置 `multi-tenant-mode`,将继续使用隔离模式(与旧版本行为一致)
|
||||
2. **向后兼容**:所有现有代码无需修改
|
||||
3. **可选升级**:如需节省资源,可配置 `multi-tenant-mode: shared` 启用共享模式
|
||||
|
||||
## 源码分析
|
||||
|
||||
issue讨论地址:[#3835](https://github.com/binarywang/WxJava/issues/3835)
|
||||
|
||||
### 为什么有两种设计?
|
||||
|
||||
1. **基础实现类的 `configMap`**:
|
||||
- 位置:`BaseWxMaServiceImpl`
|
||||
- 特点:单个 Service 实例 + 多个配置 + ThreadLocal 切换
|
||||
- 设计目的:支持在一个应用中管理多个小程序账号
|
||||
|
||||
2. **Spring Boot Starter 的 `services` Map**:
|
||||
- 位置:`WxMaMultiServicesImpl`
|
||||
- 特点:多个 Service 实例 + 每个实例一个配置
|
||||
- 设计目的:为 Spring Boot 提供更符合依赖注入风格的多租户支持
|
||||
|
||||
### 新版本改进
|
||||
|
||||
新版本通过配置项让用户自主选择实现方式:
|
||||
|
||||
```
|
||||
用户 → WxMaMultiServices 接口
|
||||
↓
|
||||
┌────┴────┐
|
||||
↓ ↓
|
||||
隔离模式 共享模式
|
||||
(多Service) (单Service+configMap)
|
||||
```
|
||||
|
||||
这样既保留了线程安全的优势(隔离模式),又提供了资源节省的选项(共享模式)。
