PreparedStatementCallback; JDBC中的錯誤SQL語法Spring

Question

我有一個更新方法來更新基於特定字段的表的內容，並且我收到以下異常。

代碼是：

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()); 
} 

的例外是：

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.

你拿TypeCategoryMapper做什麼？

,new TypeCategoryMapper()刪除
