seata 设置手动代理数据源

• 代码敬上

package org.jeecg.modules.datasource;

import com.alibaba.druid.pool.DruidDataSource;
import io.seata.rm.datasource.DataSourceProxy;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.env.Environment;

import javax.sql.DataSource;

@Configuration
public class DataSourceConfig {
 
   @Autowired
   private Environment env;

   @Bean
   public DataSource getDataSource() {
      DruidDataSource dataSource = new DruidDataSource();
      dataSource.setUrl(env.getProperty("spring.datasource.dynamic.datasource.mitu-cloud-finance.url"));
      dataSource.setUsername(env.getProperty("spring.datasource.dynamic.datasource.mitu-cloud-finance.username"));
      dataSource.setPassword(env.getProperty("spring.datasource.dynamic.datasource.mitu-cloud-finance.password"));
      dataSource.setDriverClassName(env.getProperty("spring.datasource.dynamic.datasource.mitu-cloud-finance.driver-class-name"));
      //这上面是获取配置文件中的信息，url,username,password,driverclassname等
      return dataSource;
   }

   @Primary
   @Bean("dataSource")
   public DataSourceProxy dataSource(DataSource druidDataSource) {
      return new DataSourceProxy(druidDataSource);
   }

}

• 在启动类上添加上以下注解

@Import(DataSourceConfig.class) //DataSourceConfig是上面配置文件的

• 同时在@SpringBootApplication注解上排除自动加载数据源

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
