Configure the relevant wording:

# Database connection 
jdbc: 
  username: root 
  password: root 
  path: localhost 
  Port: 3306 
  DatabaseName: demo01

Call the relevant wording:

 1  　　　　　　PreparedStatement preparedStatement = null;
 2             Connection connection = jdbcUtil.getConnection();
 3             //查询字典表获取性别code
 4             String sql = "SELECT * FROM dictionary d WHERE d.type='XBDM'";
 5             try {
 6                 preparedStatement = connection.prepareStatement(sql);
 7                 ResultSet rs = preparedStatement.executeQuery();
 8                 while (rs.next()) {
 9                     String code_name = rs.getString("code_name");
10                     //Sex determination is obtained and the dictionary table, the corresponding code value returned matches 
. 11                      IF (genderCode.equals (CODE_NAME)) {
 12 is                          String = rs.getString code ( "code" );
 13 is                          // the code to request the package body, achieve the conversion field
