统计各个数据库的各个数据表的总数，然后写入到excel中

1、最近项目基本进入最后阶段了，然后会统计一下各个数据库的各个数据表的数据量，开始使用的报表工具，report-designer，开源的，研究了两天，发现并不是很好使，最后自己下班回去，晚上思考，想着还不如自己做一个，领导下命令，说这个活给你了，你做好给经理就行了。然后就开始不断的做。思路大概如下所示：

第一步，链接各个数据源，由于项目的数据库牵扯到mysql数据库，postgresql数据库，greenplum数据库，然后mysql里面有十几个库，每个库里面有相同的数据表，然后postgresql和greenplum是一个数据库有相同的数据表。由于greenplum集群版性能很好，所以对于大数据量的话，用greenplum进行查询十分方便快捷，也是关系型数据库，和mysql的语法基本性一致。不扯这个了。

第二步，由于使用了maven项目的，所以引入依赖就行了。由于greenplum的jar包，在maven仓库里面没有找到，我就在maven项目的classpath里面引入了公司的包，如下所示：

在.classpath里面，最下面加入这一行，就引入我这个jar包。这个是公司/lib项目里面的jar包，greenplum的依赖回头再找一下。

 <classpathentry kind="lib" path="/lib/jdbc/greenplum.jar"/>

依赖如下所示：

第三步、我使用了db.properties文件。放到src\main\resources路径下面。然后由于牵扯到公司信息，这里面放了大概23个url连接。

形如如下所示：

 #.db_xxx
 db_xxx_driver=com.mysql.jdbc.Driver
 db_xxx_url=jdbc:mysql://xxx:3306/db_xxx
 db_xxx_user=xxx db_xxx_password=xxx
......

第四步，搞一个连接的工具类。大概搞23个这样的东西，重复代码就行了，然后测试一下看看是否能够连接成功。

 package com.fline.aic.utils;
 
 import java.sql.Connection;
 import java.sql.DriverManager;
 import java.sql.PreparedStatement;
 import java.sql.ResultSet;
 import java.sql.SQLException;
 import java.util.ResourceBundle;
 
 /**
  *
  * @Description TODO
  * @author biehl
  * @Date 2018年9月21日 上午9:32:04
  *
  */
 public class JdbcUtils {
 
       //
       private static String db_xxx_driver;
       private static String db_xxx_url;
       private static String db_xxx_user;
       private static String db_xxx_password;
 
       //
       static {
             db_xxx_driver = ResourceBundle.getBundle("db").getString("db_xxx_driver");
             db_xxx_url = ResourceBundle.getBundle("db").getString("db_xxx_url");
             db_xxx_user = ResourceBundle.getBundle("db").getString("db_xxx_user");
             db_xxx_password = ResourceBundle.getBundle("db").getString("db_xxx_password");
       }
 
       /**
        * 1
        * @return
        * @throws ClassNotFoundException
        * @throws SQLException
        */
       public static Connection getxxxConnection() throws ClassNotFoundException, SQLException {
             // 加载数据库驱动
             Class.forName(db_xxx_driver);
             // System.out.println("测试加载数据库成功");
             Connection con = DriverManager.getConnection(db_xxx_url, db_xxx_user, db_xxx_password);
             // System.out.println("测试数据库链接成功");
             return con;
       }
 
       /**
        *
        * @param con
        * @param ps
        * @param rs
        */
       public static void closeConnection(Connection con, PreparedStatement ps, ResultSet rs) {
             if (rs != null) {// 关闭资源，避免出现异常
                   try {
                         rs.close();
                   } catch (SQLException e) {
                         e.printStackTrace();
                   }
             }
             if (ps != null) {
                   try {
                         ps.close();
                   } catch (SQLException e) {
                         e.printStackTrace();
                   }
             }
             if (con != null) {
                   try {
                         con.close();
                   } catch (SQLException e) {
                         e.printStackTrace();
                   }
             }
       }
 
       public static void main(String[] args) {
             try {
                   JdbcUtils.getxxxConnection();
                   System.out.println("xxx前置库连接成功.....");
                   System.out.println("=======================================");
 
             } catch (ClassNotFoundException e) {
                   e.printStackTrace();
             } catch (SQLException e) {
                   e.printStackTrace();
             }
       }
 
 }

第五步、搞一个实体类，简写了这里。

 package com.fline.aic.vo;
 
 import java.io.Serializable;
 
 /**
  *
  * @Description TODO
  * @author biehl
  * @Date 2018年9月21日 上午10:50:47
  *
  */
 public class CountEntity implements Serializable {
 
     /**
      *
      */
     private static final long serialVersionUID = 1L;
     private Integer sx;// xx
     private Integer bj;// xx
     private Integer yh;// xx
     private Integer zz;// xx
 
     public Integer getSx() {
         return sx;
     }
 
     public void setSx(Integer sx) {
         this.sx = sx;
     }
 
     public Integer getBj() {
         return bj;
     }
 
     public void setBj(Integer bj) {
         this.bj = bj;
     }
 
     public Integer getYh() {
         return yh;
     }
 
     public void setYh(Integer yh) {
         this.yh = yh;
     }
 
     public Integer getZz() {
         return zz;
     }
 
     public void setZz(Integer zz) {
         this.zz = zz;
     }
 
     public CountEntity(Integer sx, Integer bj, Integer yh, Integer zz) {
         super();
         this.sx = sx;
         this.bj = bj;
         this.yh = yh;
         this.zz = zz;
     }
 
     public CountEntity() {
         super();
     }
 
     @Override
     public String toString() {
         return "CountEntity [sx=" + sx + ", bj=" + bj + ", yh=" + yh + ", zz=" + zz + "]";
     }
 
 }

第六步、查询一下，统计报表数据量。

package com.fline.aic.dao;
 
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
 
import com.fline.aic.utils.JdbcUtils;
import com.fline.aic.vo.CountEntity;
 
/**

 */
public class QueryDataOfCharts {
 
      private static QueryDataOfCharts queryDataOfCharts;
 
      private QueryDataOfCharts() {
      }
 
      public static QueryDataOfCharts getInstance() {
            if (queryDataOfCharts == null) {
                  queryDataOfCharts = new QueryDataOfCharts();
            }
            return queryDataOfCharts;
      }
 
      public Connection con = null;
      public PreparedStatement ps = null;
      public ResultSet rs = null;
 
      /**
       * 1
       *
       * @return
       */
      public CountEntity queryDbxxx() {
            try {
                  Connection xxxConnection = JdbcUtils.getxxxConnection();
                  String sql = "select\r\n"
                              + "   (sx_directory.sx + sx_general_basic.sx + sx_general_extend.sx + sx_general_material.sx + sx_general_fee_project.sx + sx_general_questions.sx + sx_punish_basic.sx + sx_punish_questions.sx + sx_handle_basic.sx + sx_handle_material.sx + sx_handle_questions.sx + sx_public_basic.sx + sx_public_extend.sx + sx_public_material.sx + sx_public_fee_project.sx + sx_public_questions.sx + sx_check_basic.sx + sx_check_questions.sx + sx_zone_organization.sx) as sx,(bj_pro_accept.bj + bj_pro_process.bj + bj_pro_result.bj + bj_pro_specialprocedure.bj + bj_pro_material.bj) as bj,(yh_uc_province_user.yh + yh_uc_corporator_identity.yh + yh_uc_corporator_account.yh + yh_uc_info_enterprise.yh + yh_uc_info_association.yh + yh_uc_info_central_dept.yh + yh_uc_gov_org.yh + yh_uc_gov_region.yh + yh_uc_gov_staff.yh) as yh,(zz_lic_data.zz) as zz\r\n"

                        ce.setZz(rs.getInt("zz"));
                        return ce;
                  } else {

                  }
            } catch (ClassNotFoundException e) {
                  e.printStackTrace();
            } catch (SQLException e) {
                  e.printStackTrace();
            }
            return null;
      }
 
      public static void main(String[] args) {
            QueryDataOfCharts instance = QueryDataOfCharts.getInstance();
            CountEntity queryDbxxx = instance.queryDbxxx();
            System.out.println(
                        "xxx " + queryDbxxx + "\n" + "=========================================================");
 
      }
 
}

其实巴拉巴拉一大堆，我感觉上面这个大sql才是比较有意思的东西。其实好好看看挺好的，就是把一类的统计相加，然后最后输出到excel里面，还是比较有意思的。

第七步，就是将查询的数据量输出到excel里面就行了：

统计报表就有意思了，将统计的数据量放到list里面，然后将list放到map里面。这样一行的都放到list里面。不同行放到不同的list里面，这样循环遍历输出的时候就可以将不同的放到不同的行里面，完美的解决我的报表统计功能。
