程序执行到sqlMap.startTransaction();报空指针

Question

我用的是spring+ibatis+struts
我在手动开启事务时报的错，程序执行到sqlMap.startTransaction();时报错，请问是什么原因？急急急！！！！java代码：
try {
String reource="sql-map-config.xml";

reader =Resources.getResourceAsReader("sql-map-config.xml");

 sqlMap =SqlMapClientBuilder.buildSqlMapClient(reader);
//  sqlMap=XmlSqlMapBuilder.buildSqlMap(reader);


sqlMap.startTransaction();
Object obj1=save(params);
System.out.println("obj1:"+obj1==null);
Object obj=save(organ);
System.out.println("obj:"+obj==null);
if((obj!=null)&&(obj1!=null)){
flag=true;
sqlMap.commitTransaction();

}else{
sqlMap.endTransaction();
}
错误信息：java.lang.NullPointerException

Answer 1

sqlMap =SqlMapClientBuilder.buildSqlMapClient(reader);
sqlMap为空，确定下你的文件名是否写正确，路径是否正确。。

Answer 2

再补充一点，我用debug调试的时候在这句抛出了异常
sqlMap =SqlMapClientBuilder.buildSqlMapClient(reader);完整的方法：
public boolean saveAll(Organ organ,Map params,String path){
Reader reader = null;
SqlMapClient sqlMap = null;
Connection conn=null;
boolean flag = false;
// Resource resource = new ClassPathResource("sql-map-config.xml");  try {
String reource="sql-map-config.xml";

reader =Resources.getResourceAsReader("sql-map-config.xml");

 sqlMap =SqlMapClientBuilder.buildSqlMapClient(reader);
//  sqlMap=XmlSqlMapBuilder.buildSqlMap(reader);


sqlMap.startTransaction();
Object obj1=save(params);
System.out.println("obj1:"+obj1==null);
Object obj=save(organ);
System.out.println("obj:"+obj==null);
if((obj!=null)&&(obj1!=null)){
flag=true;
sqlMap.commitTransaction();

}else{
sqlMap.endTransaction();
}




} catch (Exception e) {
// TODO Auto-generated catch block
System.out.println("message:"+e.getMessage());
e.printStackTrace();

}
  
return flag;
}

sql-map-config.xml在src下面，而且我打印System.out.println(sqlMap==null);时为false,你QQ是多少我加你吧，我的295833641
