The internet gave aString urls= "XXX";Response.setcontenttype ("Type=text/html;charset=utf-8");Response.getwriter (). write (URLs);This is a straight-up thing that's going to go straight to the download. That's a string.After the transformationString urls= "XXX";Response.setcontenttype ("Charset=utf-8");Response.getwriter (). write (URLs);This skips the interception of Springmvc and returns a string without a double citation!!Spring MVC
One, Java side:Define the native method, ' public native long factorial (int n); ', the method is implemented in C + +, computes ' 1 to 20 factorial and ', the argument ' int n ' is the factorial of the first n and (here is 20). Returns the result of the calculation, and return to the Java call.The code is:1 Public classFactorialjava {2 3 Public native LongFactorial (intn);4 5 //evaluate the elapse time.and the execution result.6 Public
and today I learned a function.header files: #include The Strstr () function is used to retrieve the first occurrence of a substring in a string, with the following prototype:Char *strstr (char *str, char * substr);"Parameter description" STR is the string to retrieve, substr is the substring to retrieve.Return value returns the address of the first substring substr in STR, or null if no substring is retrieved.The use of the function example Strstr ()

such as Array([0] = = Array([0] = = Array ([kd_status] = signed [kd_time] = 2014-04-30 18:59:43 [b] = 4)) This is the data that curl gets, not the array is a string.How to understand the return value of Curl_exec ()Returns TRUE on success, or FALSE on failure. However, if the Curlopt_returntransfer option is set, the execution result is returned when the function executes successfully, and FALSE on failure.PHP Gets the remote data through curl,
I met a hole today.Usually write interface, NEWHASHMAP, @ResponseBody return JSON object, no problem@RequestMapping ("url") public map F1 () { return New Hashmap(); }It's such a simple interface.Since this time I need to draw on an interface from a previous project, I copy it directly.is directly into the Modelmap object, after looking at the feeling there is no need to new a map object, direct transmission on the line.SPRINGMVC package is very good, consider quite whole, some smal
One topic requirement (merger topic)1 requires that the program must be able to handle 1000 elements; 2 Each element is of type Int32, 3 enters an array of shapes, and there are positive numbers in the array. 4 contiguous one or more integers in an array make up a sub-array, each of which has a and. 5 if the array a[0] ...

Title: Returns the and of the largest sub-array in an integer array.Requirements: Enter an integer array with positive numbers in the array;One or more consecutive integers in an array make up a sub-array, each of which has a and;The maximum value for the and of all sub-arrays. Requires a time complexity of O (n);First, design ideas1. First randomly generate an array, the length of the array is self-input, the array has positive and negative numbers.2

To return a stored process for more than one recordsetThis article first describes a stored process that returns a recordset. Sometimes, you need a storage process to return multiple recordsets, how do you get them at the same time in the ASP? To illustrate this issue, add two fields to the UserInfo table: Usertel and Usermail, and set only the Logged-in users to see both.
