(1)我的xml：
<parameterMap id= "invoiceInsertMap " class= "java.util.map " >
<parameter property= "invoicestart " jdbcType= "NUMBER " javaType= "java.lang.Long " mode= "IN "/>
<parameter property= "totalnum " jdbcType= "NUMBER " javaType= "java.lang.Integer " mode= "IN "/>
<parameter property= "invoicebookid " jdbcType= "NUMBER " javaType= "java.lang.Integer " mode= "IN "/>
</parameterMap>
<procedure id= "invoiceInsert " parameterMap= "invoiceInsertMap " >
{call invoiceInsert (?,?,?)}
</procedure>
(2)invoiceInsert 为数据库中存储过程，代码无误
(3)对外调用的接口：
public int invoiceInsert(InvoiceBook invoicebook) {
HashMap paramMap = new HashMap();
paramMap.put( "invoicestart ", invoicebook.getInvoicestart());
paramMap.put( "totalnum ", invoicebook.getInvoicedicid());
paramMap.put( "invoicebookid ", invoicebook.getInvoicebookid());
return invoiceDao.invoiceInsert(paramMap);
}
(4)invoiceDao 对xml配置中调用：
public int invoiceInsert(HashMap paramMap) {
int i=0;
try{
daoManager.startTransaction();
i=((Integer)queryForObject( "invoiceInsert ",paramMap)).intValue();
daoManager.commitTransaction();
}catch(Exception e ){
e.printStackTrace();
}
return i;
}
控制台打印的结果
{call invoiceInsert (?,?,?)}
[100000000, 20, 1]
Types: [java.lang.Long, java.lang.Integer, java.lang.Integer]
java.lang.NullPointerException
如果可以给个实例，也万分感谢!!!
------解决方案--------------------
paramMap.put( "invoicestart ", invoicebook.getInvoicestart());
paramMap.put( "totalnum ", invoicebook.getInvoicedicid());
paramMap.put( "invoicebookid ", invoicebook.getInvoicebookid());
你Debug一下看看这里面的参数是不是都有值啊？

NullPointerException是最常见的一种错误了。
我对ibatis、存储过程都不是太了解，对你的程序也了解。
不过我推测是这一句报的nullpointer：i=((Integer)queryForObject( "invoiceInsert ",paramMap)).intValue();
queryForObject返回了null，你debug一下看看
