There is a field in the action that is of the birthday or date type. When we pass the value, it must be written as to automatically convert the type, however, in some cases, you may need to write 19990101 so that automatic type conversion is not performed by default. In this way, you can write a custom type converter to achieve conversion.
Struts2 has two types of converters:
Partial: it applies to an action conversion type.
First, you need to customi

To implement a custom converter, You need to inherit the defatypetypeconverter class or the StrutsTypeConverter class from the objects to be converted, and obtain the entry of a type converter to implement the developer's own type
Typeconverter class. The description in msdn provides a unified method to convert the value type to other types, as well as access standard values and sub-attributes.Let's take a look at the example to translate a string into a type converter with a point structure.Public class pointconverter: typeconverter {Public override bool canconvertfrom (itypedescriptorcontext context, type sourcetype ){If (sourcetype = typeof (string) {return true ;}Return bas

This article describes the form token errors and solutions in ThinkPHP. We will share this with you for your reference. The details are as follows:
During project development, when adding and Editing data, the system occasionally prompts "form token error"
In the previous blog post, we obtained ACC based on the ASP. OWIN OAuth with Resource Owner Password Credentials Grant (Grant_type=password). ESS token and, with this token, successfully invokes the Web API associated with the current user (resource owner).I thought I'd done it.

I recently read a teaching video and learned socket programming. There is an example in which I feel that it is well written. I will organize it here to help me recall and view it.

How to achieve the goal:
How do I avoid duplicate submissions?
In the session, you save an array, which is stored in a successfully submitted token. In the background processing, first determine whether the token is in this array, if it exists, the description is repeated submissions.
How to check the antecedents?
Optional, this token is added to the current ses

It was because of the use of Base64 that the problem occurred when the token was sent through the Get method.
For example: http://test/test.php?a=1+2
You use $_get["a" to obtain is: 1 2, namely that the plus sign is gone. At first I used UrlEncode to convert it, but there were always one or two results that were unexpected.
Later think of Base64 characters are limited to: [a-za-z0-9\+\/=] So many, plus the problem, I will replace the plus sign withou

object to a string in some way.
To achieve these transformations, there is a magician in Struts 2.0 who can help you--converter. With it, you don't have to repeat this code over and over again:
Date birthday = dateformat.getinstance (dateformat.short). Parse (strdate);
OK, now let's take a look at an example.
