Exception details:IBatisNet. DataMapper. Exceptions. DataMapperException: This SQL map does not contain a MappedStatement named Adminf. List

After several days of this error, I checked the configuration file and xml file repeatedly, but did not check the error. Later I noticed that the SQL configuration file has a namespace, <sqlMap namespace = "Admin" xmlns = "http://ibatis.apache.org/mapping"
Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance">

For example, here I am Admin, so when I apply this sentence: return Mapper (). queryForList ("List", null); changed to return Mapper (). queryForList ("Admin. list ", null); actually yes, no error. You can read some demo programs. They don't need to write these statements. Now, I don't know what's going on, please let me know. Thank you!

(2014-9-1) Now I understand that it was originally in sqlmap. in the config file, I set useStatementNamespaces = "true". The default value is true, that is, the Satement namespace is used. Therefore, the namespace must be added during the application, because each table has select, update, and other operations, this is a good distinction, and many demo examples only operate on one table, not specifically pointed out such a situation, so it will cause such an error.
