复制中不存在Typeorm池

问题描述

typegraphql，typeorm，具有主从复制的MysqL。

我已为 MysqL 配置了具有独立实例的主数据库和从属数据库，并且工作正常。我遇到错误

通过Typeorm连接时

。这是我的 ormconfig.json

{
 "type": "MysqL","logging": true,"replication": {
 "master": 
     {
        "host": "192.168.0.250","port": 3306,"username": "root","password": "test#123","database": "master","synchronize": true,"extra": {
           "connectionLimit": 5
       }          
     },"slaves": [
  {
     "host": "192.168.0.175","extra": {
        "connectionLimit": 5
    }                
  }
 ]
 },"entities": [
   "src/entity/**/*.ts"
 ],"migrations": [
  "src/migration/**/*.ts"
 ],"subscribers": [
   "src/subscriber/**/*.ts"
 ],"cli": {
   "entitiesDir": "src/entity","migrationsDir": "src/migration","subscribersDir": "src/subscriber"
 }
 }

我的index.ts文件，数据库连接为

import { gqSchema } from './schema';
import "reflect-Metadata";
import { createConnection } from "typeorm";
import { ApolloServer } from "apollo-server";


async function main() { 
 await createConnection().then(async(res) => {
    console.log(res)
    console.log("Database Connected")
    const schema = await gqSchema()
    const server = new ApolloServer({ 
        schema,context: ({ req }: any) => ({ req })
    })
    await server.listen(4000)
    console.log("Server has started!")
}).catch(err => {
    console.log("err",err)
})    
}

main();

还有我的resolver.ts文件

@Resolver()
export class UserResolver {

 /**
 * query 
 */
@Authorized()
@Query(() => User)
async hello(
    @Arg("firstName") firstName: string,): Promise<User | undefined > {
    const slaveQueryRunner = getConnection().createqueryRunner("slave");
    try {
        const connection = getConnection().getRepository(User);
        const usersList  = await connection.createqueryBuilder()            
        .from(User,"user")
        .setQueryRunner(slaveQueryRunner)
        .where("user.firstName = ",{firstName})
        .getone();
        console.log(usersList)

    } finally {
        slaveQueryRunner.release();            
    }

    
}
}
