公司旧框架tmd 导致tomcat访问不了 连接池被占用了 JdbcProvider
错误代码如下:
try {conn=JdbcProvider.getInstance().getConnection();sm=conn.prepareStatement(sql);//办事指南rs=sm.executeQuery();while(isBSZLExsist && rs.next()){Map<String,String> map=new HashMap<String, String>();//map.put("id", rs.getString("id")); map.put("title", rs.getString("title"));map.put("docpuburl",rs.getString("docpuburl"));map.put("docreltime", rs.getString("docreltime"));list3.add(map);}System.out.println("办事指南=="+list3.size());} catch (Exception e) {// TODO: handle exceptione.printStackTrace();} //这边有问题 没有释放数据库资源if(isExsist || isContentExsist){try {sm=conn.prepareStatement(sql1);//信箱rs1=sm.executeQuery();int count = 0;while(isExsist && rs1.next()){Map<String,String> map=new HashMap<String, String>();map.put("id", rs1.getString("id"));map.put("title", rs1.getString("title"));map.put("docpuburl",rs1.getString("docpuburl"));map.put("createdate", rs1.getString("createdate"));list4.add(map);count ++;}} catch (Exception e) {e.printStackTrace();}finally{if(conn!=null){try {conn.close();} catch (SQLException e) {e.printStackTrace();}}}try {conn=JdbcProvider.getInstance().getConnection();sm=conn.prepareStatement(sql);//办事指南rs=sm.executeQuery();while(isBSZLExsist && rs.next()){Map<String,String> map=new HashMap<String, String>();//map.put("id", rs.getString("id")); map.put("title", rs.getString("title"));map.put("docpuburl",rs.getString("docpuburl"));map.put("docreltime", rs.getString("docreltime"));list3.add(map);}System.out.println("办事指南=="+list3.size());} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}finally{//正确代码if(conn!=null){//正确代码try {//正确代码conn.close();//正确代码} catch (SQLException e) {//正确代码e.printStackTrace();//正确代码}//正确代码}}if(isExsist || isContentExsist){try {conn=JdbcProvider.getInstance().getConnection();//正确代码sm=conn.prepareStatement(sql1);//信箱rs1=sm.executeQuery();int count = 0;while(isExsist && rs1.next()){Map<String,String> map=new HashMap<String, String>();map.put("id", rs1.getString("id"));map.put("title", rs1.getString("title"));map.put("docpuburl",rs1.getString("docpuburl"));map.put("createdate", rs1.getString("createdate"));list4.add(map);count ++;}} catch (Exception e) {e.printStackTrace();}finally{if(conn!=null){try {conn.close();} catch (SQLException e) {e.printStackTrace();}}}
