或者spring boot yml指定
public final static int BIT = -7;
public final static int TINYINT = -6;
public final static int SMALLINT = 5;
public final static int INTEGER = 4;
public final static int BIGINT = -5;
public final static int FLOAT = 6;
public final static int REAL = 7;
public final static int DOUBLE = 8;
public final static int NUMERIC = 2;
public final static int DECIMAL = 3;
public final static int CHAR = 1;
public final static int VARCHAR = 12;
public final static int LONGVARCHAR = -1;
public final static int DATE = 91;
public final static int TIME = 92;
public final static int TIMESTAMP = 93;
public final static int BINARY = -2;
public final static int VARBINARY = -3;
public final static int LONGVARBINARY = -4;
public final static int NULL = 0;
public final static int OTHER = 1111;
public final static int JAVA_OBJECT = 2000;
public final static int DISTINCT = 2001;
public final static int STRUCT = 2002;
public final static int ARRAY = 2003;
public final static int BLOB = 2004;
public final static int CLOB = 2005;
