1.1 问题原因：

seata 版本问题， spring-cloud-alibaba 依赖下的seata-spring-boot-starter 版本是1.1.0，而我用的seata是 1.3.0 版本。
1.3.0 版本SeataAutoConfiguration.class 没有seataDataSourceBeanPostProcessor bean ,而是用SeataAutoDataSourceProxyCreator代替。

1.3.0 版本

@Bean(BEAN_NAME_SEATA_AUTO_DATA_SOURCE_PROXY_CREATOR)
@ConditionalOnProperty(prefix = StarterConstants.SEATA_PREFIX, name = {"enableAutoDataSourceProxy", "enable-auto-data-source-proxy"}, havingValue = "true", matchIfMissing = true)
@ConditionalOnMissingBean(SeataAutoDataSourceProxyCreator.class)
public SeataAutoDataSourceProxyCreator seataAutoDataSourceProxyCreator(SeataProperties seataProperties) {
    return new SeataAutoDataSourceProxyCreator(seataProperties.isUseJdkProxy(),
        seataProperties.getExcludesForAutoProxying(), seataProperties.getDataSourceProxyMode());
    }

1.2 解决方案：

去掉spring-cloud-starter-alibaba-seata 下seata-spring-boot-starter 依赖

而且是不停的打印错误信息。

2.1 问题原因：

tx-service-group: my_test_tx_group 与配置的不统一。

2.2 解决方案：

seata:
  enabled: true
  application-id: ${spring.application.name}
  tx-service-group: my_test_tx_group  # tx-service-group 的value值 要与下面的vgroupMapping 的key 值对应。
  enable-auto-data-source-proxy: false

3.1 问题原因：

同2.1

3.2 解决方案：

同2.1 或在nacos 配置中心添加 vgroupMapping.order_tx_group

4 io.seata.common.exception.ShouldNeverHappenException: Can’t find any object of class org.springframework.context.ApplicationContext 找不到 ApplicationContext 类。

4.1 问题原因：

基本上看到 io.seata.common.exception.ShouldNeverHappenException 这个异常都是版本问题。我的是因为父工程springcloud 是Hoxton.SR3版本子工程是Hoxton.Release版。

4.2 解决方案：

统一父子工程spring cloud 版本。

5 Method nacosWatch in com.alibaba.cloud.nacos.discovery.NacosDiscoveryClientConfiguration required a single bean, but 2 were found

Method nacosWatch in com.alibaba.cloud.nacos.discovery.NacosDiscoveryClientConfiguration required a single bean, but 2 were found:
	- defaultSockJsTaskScheduler: defined by method 'defaultSockJsTaskScheduler' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketConfiguration.class]
	- messageBrokerTaskScheduler: defined by method 'messageBrokerTaskScheduler' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]

哎，没完了。nacos 又有问题了。

5.1 问题原因：

是因为项目中引用了， websocket jar包。 websocket 定时任务下有两个实例 defaultSockJsTaskScheduler和messageBrokerTaskSchedul。不清楚NacosDiscoveryClientConfiguration 为什么要注入的是单例。导致出异常，websocket 不能与nacos 兼容，这应该是nacos 的一个bug。

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-websocket</artifactId>
  </dependency>

5.2 解决方案

去掉spring-boot-starter-websocket 包

<!--        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-websocket</artifactId>
        </dependency>-->

6 mybatis 绑定返回对象出错。

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): XXX.dao.mapper.mbg.XXXMapper.queryAllList

6.1 问题原因：

代理数据源找不到mapper.xml 文件

6.2 解决方案

在SqlSessionFactory bean里加入classpath mapper路径

@Configuration
@EnableTransactionManagement
@MapperScan({"cn.test.user.dao.mapper"})
public class DataSourceProxyConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return new DruidDataSource();
    }

    @Bean
    public DataSourceProxy dataSourceProxy(@Qualifier("dataSource") DataSource dataSource) {
        return new DataSourceProxy(dataSource);
    }

    @Bean
    public SqlSessionFactory sqlSessionFactoryBean(DataSourceProxy dataSourceProxy) throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSourceProxy);
        sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver()
                .getResources("classpath*:dao/mapper/*.xml"));
        return sqlSessionFactoryBean.getObject();
    }

    @Bean
    public PageHelper pageHelper() {
        System.out.println("MyBatisConfiguration.pageHelper()");
        PageHelper pageHelper = new PageHelper();
        Properties p = new Properties();
        p.setProperty("offsetAsPageNum", "true");
        p.setProperty("rowBoundsWithCount", "true");
        p.setProperty("reasonable", "true");
        pageHelper.setProperties(p);
        return pageHelper;
    }

7.1、 nacos 配置文件

配置文件内容md5与服务器上的md5 不一致。

7.2、在yaml 配置里设置nacos 日志等级

spring:
  version: 1.0.1

  profiles:
    active: dev

logging:
  config: classpath:log/logback-spring.xml
  level:
    com.alibaba.nacos.client.*: WARN
