spring在执行sql语句时，会根据用户提供的类型参数来进行sql参数的绑定，例如：
  public int update(String sql, Object[] args, int[] argTypes) throws DataAccessException  {
return update(sql, newArgTypePreparedStatementSetter(args, argTypes));
 }
public class Types {
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;
public final static int REF = 2006;
public final static int DATALINK = 70;
public final static int BOOLEAN = 16;
// ------------------------- JDBC 4.0 -----------------------------------
public final static int ROWID = -8;
public static final int NCHAR = -15;
public static final int NVARCHAR = -9;
public static final int LONGNVARCHAR = -16;
public static final int NCLOB = 2011;
public static final int SQLXML = 2009;
}
其中argTypes里面设定了args参数数组里面每个对象的sql类型。最终spring设置参数的方法如下：
private static void setValue(PreparedStatement ps, int paramIndex, int sqlType, String typeName,
Integer scale, Object inValue) throws SQLException {
  if (inValue instanceof SqlTypeValue) {
((SqlTypeValue) inValue).setTypeValue(ps, paramIndex, sqlType, typeName);
 }
else if (inValue instanceof SqlValue) {
((SqlValue) inValue).setValue(ps, paramIndex);
}
else if (sqlType == Types.VARCHAR || sqlType == Types.LONGVARCHAR ||
(sqlType == Types.CLOB && isStringValue(inValue.getClass()))) {
ps.setString(paramIndex, inValue.toString());
}
else if (sqlType == Types.DECIMAL || sqlType == Types.NUMERIC) {
if (inValue instanceof BigDecimal) {
ps.setBigDecimal(paramIndex, (BigDecimal) inValue);
}
else if (scale != null) {
ps.setObject(paramIndex, inValue, sqlType, scale);
}
else {
ps.setObject(paramIndex, inValue, sqlType);
}
}
else if (sqlType == Types.DATE) {
if (inValue instanceof java.util.Date) {
if (inValue instanceof java.sql.Date) {
ps.setDate(paramIndex, (java.sql.Date) inValue);
}
else {
ps.setDate(paramIndex, new java.sql.Date(((java.util.Date) inValue).getTime()));
}
}
else if (inValue instanceof Calendar) {
Calendar cal = (Calendar) inValue;
ps.setDate(paramIndex, new java.sql.Date(cal.getTime().getTime()), cal);
}
else {
ps.setObject(paramIndex, inValue, Types.DATE);
}
}
else if (sqlType == Types.TIME) {
if (inValue instanceof java.util.Date) {
if (inValue instanceof java.sql.Time) {
ps.setTime(paramIndex, (java.sql.Time) inValue);
}
else {
ps.setTime(paramIndex, new java.sql.Time(((java.util.Date) inValue).getTime()));
}
}
else if (inValue instanceof Calendar) {
Calendar cal = (Calendar) inValue;
ps.setTime(paramIndex, new java.sql.Time(cal.getTime().getTime()), cal);
}
else {
ps.setObject(paramIndex, inValue, Types.TIME);
}
}
else if (sqlType == Types.TIMESTAMP) {
if (inValue instanceof java.util.Date) {
if (inValue instanceof java.sql.Timestamp) {
ps.setTimestamp(paramIndex, (java.sql.Timestamp) inValue);
}
else {
ps.setTimestamp(paramIndex, new java.sql.Timestamp(((java.util.Date) inValue).getTime()));
}
}
else if (inValue instanceof Calendar) {
Calendar cal = (Calendar) inValue;
ps.setTimestamp(paramIndex, new java.sql.Timestamp(cal.getTime().getTime()), cal);
}
else {
ps.setObject(paramIndex, inValue, Types.TIMESTAMP);
}
}
else if (sqlType == SqlTypeValue.TYPE_UNKNOWN) {
if (isStringValue(inValue.getClass())) {
ps.setString(paramIndex, inValue.toString());
}
else if (isDateValue(inValue.getClass())) {
ps.setTimestamp(paramIndex, new java.sql.Timestamp(((java.util.Date) inValue).getTime()));
}
else if (inValue instanceof Calendar) {
Calendar cal = (Calendar) inValue;
ps.setTimestamp(paramIndex, new java.sql.Timestamp(cal.getTime().getTime()), cal);
}
else {
// Fall back to generic setObject call without SQL type specified.
ps.setObject(paramIndex, inValue);}
}
else {
// Fall back to generic setObject call with SQL type specified.
ps.setObject(paramIndex, inValue, sqlType);
}
当我们没有给spring的相应方法传递参数类型的时候，例如调用：
public int update(String sql, Object args) throws DataAccessException {
return update(sql, newArgPreparedStatementSetter(args));
}
最终表现为SqlTypeValue.TYPE_UNKNOWN，对于非String，Date,Calendar 类型的对象对，spring将通过ps.setObject(paramIndex, inValue)进行参数设置，也就是交给我们的jdbc驱动（eg:jdbc6.jar）来进行设置,驱动程序会根据传递的对象来进行类型的转换并进行参数设置：
其中java类型到sql类型的转换如下：
oracle.jdbc.driver.OraclePreparedStatement
int sqlTypeForObject(Object paramObject)
{
if (paramObject == null)
{
return 0;
}
if (!(paramObject instanceof Datum))
{
if ((paramObject instanceof String))
{
return this.fixedString ? 999 : 12;
}
if ((paramObject instanceof BigDecimal)) {
return 2;
}
if ((paramObject instanceof Boolean)) {
return -7;
}
if ((paramObject instanceof Integer)) {
return 4;
}
if ((paramObject instanceof Long)) {
return -5;
}
if ((paramObject instanceof Float)) {
return 7;
}
if ((paramObject instanceof Double)) {
return 8;
}
if ((paramObject instanceof byte[])) {
return -3;
}
if ((paramObject instanceof Short)) {
return 5;
}
if ((paramObject instanceof Byte)) {
return -6;
}
if ((paramObject instanceof Date)) {
return 91;
}
if ((paramObject instanceof Time)) {
return 92;
}
if ((paramObject instanceof Timestamp)) {
return 93;
}
if ((paramObject instanceof SQLData)) {
return 2002;
}
if ((paramObject instanceof ObjectData))
return 2002;
}
其中驱动里面oracle的类型定义如下，和jdk里面Types类定义的基本对应。
public abstract class OracleTypes
{
public static final int BIT = -7;
public static final int TINYINT = -6;
public static final int SMALLINT = 5;
public static final int INTEGER = 4;
public static final int BIGINT = -5;
public static final int FLOAT = 6;
public static final int REAL = 7;
public static final int DOUBLE = 8;
public static final int NUMERIC = 2;
public static final int DECIMAL = 3;
public static final int CHAR = 1;
public static final int VARCHAR = 12;
public static final int LONGVARCHAR = -1;
public static final int DATE = 91;
public static final int TIME = 92;
public static final int TIMESTAMP = 93;
/** *//** @deprecated */
public static final int TIMESTAMPNS = -100;
public static final int TIMESTAMPTZ = -101;
public static final int TIMESTAMPLTZ = -102;
public static final int INTERVALYM = -103;
public static final int INTERVALDS = -104;
public static final int BINARY = -2;
public static final int VARBINARY = -3;
public static final int LONGVARBINARY = -4;
public static final int ROWID = -8;
public static final int CURSOR = -10;
public static final int BLOB = 2004;
public static final int CLOB = 2005;
public static final int BFILE = -13;
public static final int STRUCT = 2002;
public static final int ARRAY = 2003;
public static final int REF = 2006;
public static final int NCHAR = -15;
public static final int NCLOB = 2011;
public static final int NVARCHAR = -9;
public static final int LONGNVARCHAR = -16;
public static final int SQLXML = 2009;
public static final int OPAQUE = 2007;
public static final int JAVA_STRUCT = 2008;
public static final int JAVA_OBJECT = 2000;
public static final int PLSQL_INDEX_TABLE = -14;
public static final int BINARY_FLOAT = 100;
public static final int BINARY_DOUBLE = 101;
public static final int NULL = 0;
public static final int NUMBER = 2;
public static final int RAW = -2;
public static final int OTHER = 1111;
public static final int FIXED_CHAR = 999;
public static final int DATALINK = 70;
public static final int BOOLEAN = 16;
private static final String _Copyright_2007_Oracle_All_Rights_Reserved_ = null;
public static final String BUILD_DATE = "Fri_Jul_31_19:30:28_PDT_2009";
public static final boolean TRACE = false;
public static final boolean PRIVATE_TRACE = false;
}
最终驱动程序将根据转换的类型进行参数绑定，具体如下：
void setObjectCritical(int paramInt1, Object paramObject, int paramInt2, int paramInt3)
throws SQLException
{
SQLException localSQLException;
switch (paramInt2)
{
case 1:
