使用java代码动态在oracle数据库中动态创建表

一.jdbcTemplate的配置
package com.djhu.followup.config;

    import com.alibaba.druid.pool.DruidDataSource;
    import com.djhu.api.util.MybatisInterceptor;
    import org.apache.ibatis.plugin.Interceptor;
    import org.apache.ibatis.session.SqlSessionFactory;
    import org.mybatis.spring.SqlSessionFactoryBean;
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.beans.factory.annotation.Qualifier;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
    import org.springframework.jdbc.core.JdbcTemplate;

    import javax.sql.DataSource;

/**

• @Author zw

• @DATE 2019/5/9 15:18

• @VERSION 1.0.0
  */
  @Configuration
  @MapperScan(basePackages = FollowUpDbConfig.PACKAGE,sqlSessionFactoryRef=“followUp_SqlSessionFactory”)
  public class FollowUpDbConfig {
  static final String PACKAGE = “com.djhu.followup.dao.followup”;
  static final String MAPPER_LOCATION = "classpath:followup/*.xml";
  static final String CONFIG_LOCATION = “classpath:mybatis-config.xml”;
  @Value("${jdbc.url}")
  private String url;

  @Value("${jdbc.username}")
  private String user;

  @Value("${jdbc.password}")
  private String password;

  @Value("${jdbc.driver}")
  private String driverClass;

  @Bean(name = “followUpDataSource”)
  public DataSource followUpDataSource() {
  // try {
  // Thread.sleep(3000L);
  // } catch (InterruptedException e) {
  // // TODO Auto-generated catch block
  // e.printStackTrace();
  // }
  DruidDataSource followUpDataSource = new DruidDataSource();
  followUpDataSource.setDriverClassName(driverClass.trim());
  followUpDataSource.setUrl(url.trim());
  followUpDataSource.setUsername(user.trim());
  followUpDataSource.setPassword(password.trim());
  followUpDataSource.setInitialSize(5);
  followUpDataSource.setMinIdle(1);
  followUpDataSource.setMaxActive(10);
  followUpDataSource.setPoolPreparedStatements(false);
  return followUpDataSource;
  }

//注入模板类
@Bean(name = “followupJdbcTemplate”)
public JdbcTemplate getJdbcTemplate(@Qualifier(“followUpDataSource”) DataSource followUpDataSource){
return new org.springframework.jdbc.core.JdbcTemplate(followUpDataSource);
}

@Bean(name = "followUp_SqlSessionFactory")
public SqlSessionFactory followUpClusterSqlSessionFactory(@Qualifier("followUpDataSource") DataSource followUpDataSource)
        throws Exception {
    SqlSessionFactoryBean followUp_SqlSessionFactory = new SqlSessionFactoryBean();
    followUp_SqlSessionFactory.setDataSource(followUpDataSource);
    followUp_SqlSessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()
            .getResources(MAPPER_LOCATION));
    followUp_SqlSessionFactory.setConfigLocation(new PathMatchingResourcePatternResolver().getResource(CONFIG_LOCATION));
    Interceptor[] interceptors= {new MybatisInterceptor()};
    followUp_SqlSessionFactory.setPlugins(interceptors);
    return followUp_SqlSessionFactory.getObject();
}

}

二.方法内部使用
public static final String TABLE_NAME_PREFIX = “patient_info”;

  @Autowired
   private JdbcTemplate jdbcTemplate;
	 String tableId = this.baseMapper.patientTableId();//
    String table = Joiner.on("_").join(TABLE_NAME_PREFIX,tableId);// “自定义”

    log.info("创建随访人员表 ,表名是  {}", table);
        File file = new File("./config/create.sql");
        InputStream fileInputStream = null;
        try {
         fileInputStream = new FileInputStream(file);
            String line = IOUtils.toString(fileInputStream);
            String createSql = String.format(line, table);
            createSql = createSql.replaceAll("\r|\n", "");
            log.info("创建随访人员表,建表语句是 :");
            log.info(createSql);
            jdbcTemplate.execute(createSql);
            log.info("创建随访人员表成功.");
            return true;
        } catch (Exception e) {
            log.error("创建表失败!!!,table name is {}",table);
            return false;
        } finally {
            IOUtils.closeQuietly(fileInputStream);
        }
