springboot+springJdbc+postgresql 实现多数据源的配置

作者：董懂

本文主要介绍了springboot+springJdbc+postgresql 实现多数据源的配置，文中通过示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

背景

最近公司在服务拆迁,接口转移,相同的功能接口到要迁移到对应的服务中,因为时间比较赶,别问为什么没给时间,没人,没资源,但是活还是得干的,为了减少工作量和稳妥的需要分两步走

实施

配置文件

数据库配置相关类

import com.alibaba.druid.pool.DruidDataSource;

import java.io.Serializable;
import java.sql.SQLException;

public class JdbcConfig implements Serializable {
   public JdbcConfig() {
      super();
      // TODO Auto-generated constructor stub
   }

   public boolean isDecrypt() {
      return decrypt;
   }

   public void setDecrypt(boolean decrypt) {
      this.decrypt = decrypt;
   }

   public String getDriverClass() {
      return driverClass;
   }

   public void setDriverClass(String driverClass) {
      this.driverClass = driverClass;
   }

   public String getTerminalUrl() { return terminalUrl; }

   public void setTerminalUrl(String terminalUrl) { this.terminalUrl = terminalUrl;   }

   public String getSlaveurl() {
      return slaveurl;
   }

   public void setSlaveurl(String slaveurl) {
      this.slaveurl = slaveurl;
   }

   public String getUsername() {
      return username;
   }

   public void setUsername(String username) {
      this.username = username;
   }

   public String getPassword() {
      return password;
   }

   public void setPassword(String password) {
      this.password = password;
   }

   public int getInitialSize() {
      return initialSize;
   }

   public void setInitialSize(int initialSize) {
      this.initialSize = initialSize;
   }

   public int getMinIdle() {
      return minIdle;
   }

   public void setMinIdle(int minIdle) {
      this.minIdle = minIdle;
   }

   public int getMaxActive() {
      return maxActive;
   }

   public void setMaxActive(int maxActive) {
      this.maxActive = maxActive;
   }

   private boolean decrypt;
   private String driverClass;
   private String terminalUrl;
   private String slaveurl;
   private String username;
   private String password;
   private int initialSize;
   private int minIdle;
   private int maxActive;

   public DruidDataSource mainds() throws SQLException {
      DruidDataSource ds = ds();
      ds.setUrl(terminalUrl);
      return ds;
   }

   public DruidDataSource slaveds() throws SQLException {
      DruidDataSource ds = ds();
      ds.setUrl(slaveurl);
      return ds;
   }

   private DruidDataSource ds() throws SQLException {
      DruidDataSource ds = new DruidDataSource();
      ds.setUrl(terminalUrl);
      ds.setUsername(username);
      ds.setPassword(password);
      ds.setFilters("config");
      ds.setConnectionProperties("config.decrypt=" + decrypt);
      ds.setInitialSize(initialSize);
      ds.setMaxActive(maxActive);
      ds.setTimeBetweenEvictionRunsMillis(60000);
      ds.setMinEvictableIdleTimeMillis(300000);
      ds.setValidationQuery("select 'X'");
      ds.setTestWhileIdle(true);
      ds.setTestOnBorrow(false);
      ds.setTestOnReturn(false);

      System.out.println("terminalUrl: " + terminalUrl);
      return ds;

   }
}

相关配置

@Bean
@ConfigurationProperties(prefix = "jdbc")
public JdbcConfig jdbcConfig() {
   return new JdbcConfig();
}
@Bean
@ConfigurationProperties(prefix = "business.jdbc")
public JdbcConfig businessJdbcConfig() {
   return new JdbcConfig();
}

@Bean(initMethod = "init", destroyMethod = "close")
public DruidDataSource businessDataSource() throws SQLException {
   return businessJdbcConfig().mainds();
}

@Bean(initMethod = "init", destroyMethod = "close")
public DruidDataSource masterDataSource() throws SQLException {
   return jdbcConfig().mainds();
}

@Bean("jdbctemplate")
public JdbcTemplate jdbcTemplate() throws SQLException {
   JdbcTemplate t = new JdbcTemplate();
   t.setDataSource(masterDataSource());
   return t;
}

@Bean("businessJdbctemplate")
public JdbcTemplate businessjdbcTemplate() throws SQLException {
   JdbcTemplate t = new JdbcTemplate();
   t.setDataSource(businessDataSource());
   return t;
}

使用

@Bean
public RobotDataDao robotDataDao() throws SQLException {
   RobotDataDao dao = new RobotDataDao();
   dao.setJdbcTemplate(jdbcTemplate());
   dao.setTableName("t_business_robot_data");
   dao.setPrimaryKey("id");
   dao.setSeqName("seq_t_business");
   return dao;
}

@Bean
public VDeviceDao vdeviceDao() throws SQLException {
   VDeviceDao dao = new VDeviceDao();
   dao.setJdbcTemplate(businessjdbcTemplate());
   dao.setTableName("t_device");
   dao.setPrimaryKey("id");
   dao.setSeqName("seq_t_default");
   return dao;
}

特别注意的,一定要配置的,因为现在有多数据源了就要配置对应的事务配置,单个默认的,多个就要指定

@Configuration
public class TransactionConfig  {
    @Bean
    public PlatformTransactionManager bfscrmTransactionManager(@Qualifier("masterDataSource") DataSource masterDataSource) {
        return new DataSourceTransactionManager(masterDataSource);
    }
}

这就配置好了多个数据源了
