我有一种更新方法，可以根据特定字段更新表的内容，并且出现以下异常。
代码是：
public void updateTaxoActive(String oldDesc, String description) {
Logger.getLogger(TypeCategoryJDBCTemplate.class.getName()).log(Level.INFO, "old taxonomy code is {0} new description is {1}", new Object[]{oldDesc, description});
String sql = "update product.typecategory set taxonomydescription = ? where taxonomydescription = ?";
jdbcTemplateObject.update(sql, new Object[]{description,oldDesc},new TypeCategoryMapper());
}
例外是：
Exception in thread "AWT-EventQueue-0" org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [update product.typecategory set taxonomydescription = ? where taxonomydescription = ?]; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][1091][10824][4.13.127] Invalid data conversion: Parameter instance [Ljava.lang.Object;@1dc421 is invalid for the requested conversion.

您在用TypeCategoryMapper做什么？
删除,new TypeCategoryMapper()
