How to figure out which class to use in Spring? -


I have some code that parses text data in java objects, many parsers based on the JSN value are available. Like when type = 1, use parser1, use type = 2 parser2 etc.

My code is like the following: 

  interface pars {data pars (input data); } Class Parser1 implementer Parser {} Class Parser2 Tools Persers {} Switch (Type) {Case 1: Return Pace 1 Paras (data); Case 2: Return Pace 2 Paras (data); Default: return zero; }   
 I do not like the check type manually and manually select parsed. Is spring a way to handle parser with mapping type?  
 Thank you!   
 
 
 You can not escape the check for mapping, you must tell the spring in the same way or Second, the parser must be selected in each state.  
 You can apply it very well by using parseffects. The parser method will be found for example:  
  public class parserfactor {@Autowire @Qualifier ("parser1" Parser parser 1; @ Etowair @ qualifier ("parser 2") parser parser 2; Public static parser picar (string value) {if (value.equals ("x")} {return parser1; } And if (value.equals ("y")) {return parser2; If you want, you can create a list of parsers and configure it with @resource annotations.  
 You can instantiate your parser using SpringConfig XML:  
  & lt; Bean id = "parse 1" class = "com.mycompany.parsers.Parser1" /> & Lt; Bean id = "parser 2" class = "com.myCompany.parsers.Parser2" />

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
