oracle异常错误断点,错误提示：SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [null]; e

Tomcat提示错误如下：

INFO [org.springframework.beans.factory.xml.XmlBeanDefinitionReader] - Loading XML bean definitions from class path resource [org/springframework/jdbc/support/sql-error-codes.xml]

INFO [org.springframework.jdbc.support.SQLErrorCodesFactory] - SQLErrorCodes loaded: [DB2, Derby, H2, HSQL, Informix, MS-SQL, MySQL, Oracle, PostgreSQL, Sybase]

org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [null]; error code [17004];

--- The error occurred in sqlmap-mapping-operate.xml.

--- The error occurred while applying a parameter map.

--- Check the logSave-InlineParameterMap.

--- Check the parameter mapping for the 'coclorFlag' property.

---Cause:java.lang.NullPointerException

最后检查入参时，发现：

Map map = new Hash();

map.put("coclorFlag",  '1');

---java代码中， 对于常量值应该用双引号（" "）  来使用， 单引号（' '）无用；
