Spring MVC returns the json format. springmvc returns the json format.
When SpringMVC framework is used to directly return json data to the client, different versions may vary.
The following describes how to configure two types of versions.

First of all, I need to take over a project recently. I want to parse binary data at the underlying layer. The data structure is quite responsible. Because the server is a c ++ server, and I didn't take mobile development into account at the beginning, so the protocol is a bit bullshit! In general, a data packet contains a vector in the map and is serialized into a binary value! Ios make
Label:MSDN to the official explanation: These three functions all return the last generated identity value. However, the "last" scope and the session defined in each of these functions are different. 1. Ident_current returns the most recent identity value generated for a session and the specified table in the current scope. If the Ident_current value is NULL (because the table never contains rows or has been truncated), the Ident_current function

The only downside to the MySQL Extract () function is that you need to hit the keyboard a few more times.

Next () Definition and usage
The next () function moves the pointer to the current element to the position of the next element and returns the value of the element.
If the internal pointer already exceeds the last element of the array, the function returns FALSE.

Note: You need to work with the appropriate operation, otherwise the value returned is only 1 and 1 (all incorrect values)
Example:
Drop database if exists ' mytest ';
Create database ' mytest ';
Use ' mytest ';
drop table if exists ' mytesttable ';
CREATE TABLE ' mytesttable ' (' ID ' int, ' Name ' varchar (10));
Insert INTO ' mytesttable ' (' ID ', ' Name ')
Select ' 1 ', ' role1 ' UNION ALL

If we want to define a function that returns an array pointer, the dimension of the array must follow the name of the function, but after the function name is the formal parameter list, the formal parameter list should precede the dimension of the array. The function that returns an array pointer is as follows:Type (*function (parameter_list)) [Dimension]The declaration of the Func function below does not u
PHP array_values
The PHP array_values function returns all the values in the array, noting that the function will set up an array index for the new array, and the original text index will not exist. This article explains the basic syntax and usages of the array_values function.

Both the client and server applications use the RECV function to receive data from the other end of the TCP connection.
The first parameter of the function specifies a receive-side socket descriptor;
The second parameter indicates a buffer, which is used to hold the data received by the RECV function;
The third parameter indicates the length of the BUF;
