Seata分布式事务控制整合Mybatis-Plus导致事务控制失效

解决方案

1. pom文件引入Druid数据源

com.alibaba
druid-spring-boot-starter
1.1.10

注意：这里引入的是SpringBoot整合的Druid依赖，数据源信息直接配置在spring.datasource下即可。

2. application.yml配置数据源信息

spring:
  application:
    name: seata-order-service
  cloud:
    alibaba:
      seata:
        #自定义事务组名称需要与seata-server中的对应
        tx-service-group: my_test_tx_group
    nacos:
      discovery:
        server-addr: localhost:8848
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/seata_order?serverTimezone=GMT%2B8&allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=utf-8
    username: xxxxx
    password: xxxxx

3. 配置数据源、数据源代理及SqlSessionFactory

import com.alibaba.druid.pool.DruidDataSource;
import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
import io.seata.rm.datasource.DataSourceProxy;
import org.apache.ibatis.session.SqlSessionFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import javax.sql.DataSource;


@Configuration
public class DruidDataSourceConfig {

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

    @Bean  // 注意：这里DataSourceProxy导的是seata的包
    public DataSourceProxy dataSourceProxy(DataSource dataSource) {
        return new DataSourceProxy(dataSource);
    }

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

}

注意：这里使用的SqlSessionFactoryBean是Mybatis的，否则会导致Mybatis-Plus的自动填充失效，将会出现如下错误信息（org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)）：
