Troubleshooting of Ext. Direct loading and submission in ExtJS

I burst into tears and finally finished part of ExtJS.
(If the foundation is solid, it will be helpful. It will be reflected in troubleshooting)
Next we will take some troubleshooting notes on Ext. Direct:

Error 1:

Why?
Answer:
@ DirectFormPostMethod
This is not correct. The above error is generated and changed to @ DirectMethod.
Delete the output generated by @ DirectFormPostMethod at the same time:
Copy codeThe Code is as follows:
Import com. softwarementors. extjs. djn. config. annotations. DirectFormPostMethod;

Error 2:

An error occurs at the control layer, that is, the logic is incorrect. The input parameters in my function are not consistent with the submitted parameters,
Don't worry, it's not about xml configuration, it's about input parameters. So the focus is on parameters, that is, syntax.

My error cause:
Java requires two input parameters:
Copy codeThe Code is as follows:
Public Info submitData (String name, String password)

In ExtJS, the actual input parameter is:
Copy codeThe Code is as follows:
Var params = username. getValue () + Password. getValue ();
FormAction. submitData (params, function (result, e ){}

Just rewrite it:
Copy codeThe Code is as follows:
FormAction. submitData (username. getValue (), Password. getValue (), function (result, e ){}

The reason is that this class does not exist.:
Com. softwarementors. extjs. djn. test. config. GsonBuilderConfiguratorForTesting
This error is found in web. xml and deleted:
Copy codeThe Code is as follows:
<Init-param>
<Param-name> registryConfiguratorClass </param-name>
<Param-value> com. softwarementors. extjs. djn. test. servlet. config. RegistryConfiguratorForTesting </param-value> </init-param>
<Init-param>
<Param-name> gsonBuilderConfiguratorClass </param-name>
<Param-value> com. softwarementors. extjs. djn. test. config. GsonBuilderConfiguratorForTesting </param-value> </init-param>

This is probably the case with me.
