seata升级1.1.0后遇到io.seata.common.exception.ShouldNeverHappenException

我们这一节主要讲的是seata升级后的主要修改，至于seata的基本部署可以参考我之前的随笔。
一开始我在升级SpringBoot版本之后，seata就突然启动不起来了，报了下面的错：
Caused by: io.seata.common.exception.ShouldNeverHappenException: Auto proxy of DataSource can't be enabled as you've created a DataSourceProxy bean.Please consider removing DataSourceProxy bean or disabling auto proxy of DataSource.

原因:在github上找到：https://github.com/seata/seata/issues/2469

解决方案如下:

在1.1.0版本升级之后，seata不支持手动代理，所以只需创建普通的数据源bean就行：

顺便说一下1.1.0之后

可以在yml配置file.conf和registry.conf
我们可以删掉file.conf和registry.conf这两个配置文件了，直接用yml就可以配置seata：

#seata配置
seata:
  enabled: true
  # 你的服务名称
  application-id: ${spring.application.name}
  #这里的名字与seata服务端的file.conf中vgroup_mapping.my_test_tx_group = "seata-server"相同
  tx-service-group: fsp_tx_group
  # 开启数据源自动代理
  enable-auto-data-source-proxy: true
  #  可以指定动态代理
  #  use-jdk-proxy: false
  service:
    vgroup-mapping:
      #这里对应端的file.conf中vgroup_mapping.fsp_tx_group = "default"
      fsp_tx_group: default
    grouplist:
      default: 127.0.0.1:8091
  config:
    type: file
    file:
      name: file.conf
  # Eureka配置
  registry:
    type: nacos
    nacos:
      server-addr: "127.0.0.1:8848"
      namespace:
      cluster: "default"
