No artifacts package solution for idea to configure Tomcat

I don’t know why my idea is always inexplicably wrong, maybe it is aimed at me
1. At this point you can see that there are no artifacts and there are warnings in the bottom that cause Tomcat to not be successfully configured

2. The solution I found on the Internet is to check this box, but my default is that the box does not solve my problem
 

3. I updated the Maven environment and solved it successfully

Conclusion: Just update the Maven environment
 

Git authentication failed

Enter the command to clear the login and password

git config --system --unset credential.helper

And then when you push
it’s going to pop up the login window again
Use the following command to configure login free

 git config  credential.helper store

Problem solving – vs debugging window flash solution

1. Test procedure:

#include "StdAfx.h"
#include <iostream>

using namespace std;

int main()
{ 
	int radius;
	const double pi(3.14926);
	cout<<"Please input R:";
	cin>>radius;
	cout<<"R is:"<<radius<<endl;
	cout<<"S is:"<<pi*radius*radius<<endl;
	return 0;
}

2. Solutions
(1) If the operation is compile (F5), flash, you can run the program first (Ctrl+F5), will not flash.
(2) If the above methods do not work
1. Right-click Current Project – Properties
2. Select Configuration Properties – Linker – System
. Change the SUBSYSTEM configuration in System Options and select the first/CONSOLE from the drop-down menu.

Then select “Start (Not Debug) “, that is, press Ctrl +F5;
(3) or program manipulation
In a C++ file, add: system(“pause”) before the last line (return) of the program;
In the case of a C file, the program header adds a header: #include”stdlib.h”; Then add: system(“pause”) at the end of the program (before return); .
(4) Set the breakpoint, and then debug (F5), also can.

CMake error: error in configuration process, project files may be invalid

It is very strange that following the installation steps of others, there is a problem, (OK, actually I was in the process of installation, I was typing, I don’t know, press the wrong button)

You can check for specific errors in Cmake:

Boost_root is an environment variable that should be used in the process of installing BOOSTPRO. The BOOST_ROOT is an environment variable that should be used in the process of installing BOOSTPRO. The BOOST_ROOT is an environment variable. I added myself to this file

Error in VTK-6.3.0 using VTKVolumerayCastMapper for volume rendering:

Generic Warning: In D:\VTK\VTK-6.3.0\Rendering\Volume\vtkRayCastImageDisplayHelper.cxx, line 20
Error: no override found for 'vtkRayCastImageDisplayHelper'.

1 Solutions
At the beginning of main() add:

VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);

2. Solution Process
How do you know the above VTKrenderingVolumeOpenGL?In VTK Error: No Override Founds for ‘VTKVolumetTextureMapper2D’, a method is already provided, but there are some difficulties in practice. Here is a better method. Here are the detailed steps.
(1) Find a case of VTKVolumerayCastMapper through the help document of VTK-6.3.0:

(2) Find the directory of Medical4.cxx (VTK-6.3.0/Examples/Medical/) in the VTK-6.3.0 source code. There is a cMakelists.txt file in it:

(3) Open the above cmakelist.txt file and find the contents of the find_package section:

VTKRenderingVolume $(VTK_Rendering_Backend) is the module required for VTKVolumerayCastMapper. So what is the value of VTK_RENDERING_BACKEND?
(4) open the VTK 6.3.0/Rendering/Volume/CMakeList. TXT, in its final value judgment about VTK_RENDERING_BACKEND:

So you can guess that VTK_RENDERING_BACKEND refers to a version of OpenGL, either OpenGL or OpenGL2. OpenGL is used by default in VTK-6.3.0 (VTK-7.0.0 has been changed to OpenGL2), so the value of VTK_RENDERING_BACKEND is OpenGL or OpenGL2, and the former is chosen in this paper.

Solution of project error reporting in eclipse

I. The project has a Red Cross:

Target runtime MyEclipse Tomcat V7.0 Unknown Faceted Project Problem
br> Target runtime MyEclipse Tomcat V7.0 Unknown Faceted Project Problem

2. To find the project directory. Mon. Under the Settings of org.eclipse.wst.com project. Facet. XML core.

3. Will & lt; The runtime name = “MyEclipse Tomcat v7.0″/& gt; Delete, and then right-click the project and refresh.

Second, the projects have a red exclamation point
right click – buildPath – see each TAB to see if there is failure jars or path error
Three, didn’t find the sessionFactory project appear this error:
the solution: (need SRC and res) in both directory to compile project right – buildPath – source – addFolder – check the res and SRC – ok

Right-click on the project –buildPath–Libraries– select JRE System Library–Edit– select Workspace Default JRE


Five, the project after import the captcha code error:

3, [Project] -> Properties -> Java Build Path -> Libraries -> Double-click the JRE System Library and change it to “Workspace Default JRE”

Six, because of the relationship between work, Eclipse development of Java projects to copy, sometimes report a very strange error. Java Compiler Level does not match the version of the installed Java project facet “Java Compiler Level does not match the version of the installed Java project facet” when the source code is identical.
it is very easy to solve, actually under the resource manager, find the project directory, in. Settings subdirectories inside, use a text editor open org.eclipse.wst.com mon. Project. Facet. Core. The XML configuration file
content is as follows:
& lt; ?The XML version = “1.0” encoding = “utf-8”?>
& lt; faceted-project>
& lt; runtime name=”com.genuitec.runtime.generic.jee70″/>
& lt; fixed facet=”jst.web”/>
& lt; fixed facet=”wst.jsdt.web”/>
& lt; fixed facet=”java”/>
& lt; Installed facet = “Java” version = “1.7”/& gt;
& lt; Installed facet = “JST. Web” version = “3.1”/& gt;
& lt; Installed facet = “JST. Web. JSTL” version = “1.2.2”/& gt;
& lt; Installed facet = “WST. JSDT. Web” version = “1.0”/& gt;
& lt; /faceted-project>

& lt; Installed facet = “Java” version = “1.7”/& gt;

:
:
the right mouse button to select the project, click Properties, select the Java Compiler, you can see on the right side window to the Compiler version
check the Enable project specific Settings
check Use default the compliance Settings
the selection of the corresponding version into in accordance with the version = “1.7”

MySQL restart error the server quit without updating PID file

Objective: To turn on MySQL binlog.
environment: CentOS6.5, MySQL5.6.10.
question: Starting MySQL… ERROR! The server quit without updating The PID file (/ var/lib/mysql/common PID).
view: in the MySQL data directory to view the log, the log named hostname. Err, after view there is the following error message. It is verified to be a bug of MySQL version.

solution: use the log – bin =/var/lib/mysql/mysql – bin instead of the original three lines of configuration. The modified restart was successful.
validation: execute SQL:

show variables like '%log_bin%';

As a result, the Binlog log was successfully turned on.

LINK : error LNK2001: unresolved external symbol _mainCRTStartup

During the process of OpenCV Tutorial Foundation, after solving the problem OpenCV Error Note _error LNK2001: Unresolved External Symbol _cvGEMM, the following problems occurred:
LINK : error LNK2001: unresolved external symbol _mainCRTStartup
.
Solution: Click the Reset button in the figure below and redo it according to OpenCV Error Note _error LNK2001: Unresolved External Symbol _cvGEMM.

Reason: It may be that in the process of operating OpenCV error note _error LNK2001: Unresolved External Symbol _cvGEMM, an error was modified somewhere!

failed: Error during WebSocket handshake: Unexpected response code: 200

This problem is often encountered when webSocket connections are made. A comparison between previous projects and current WebSockets shows that there is an additional blocking function. Therefore, it is generally found that the reason lies in the interceptor to see whether the webSocket request address is blocked by the interceptor.

Windows problem loadlibrary failed, GetLastError = 193

LoadLibrary A.dll failed, and GetLastError returns 193, %1 is not a valid Win32 application.
Maybe the b. DLL associated with a. DLL is not updated, such as a new DLL with a new interface (GetVersion) in the application, and the current B.DLL is not updated, resulting in a 193 error. The dynamically loaded library depends on other dynamic libraries, and you just replace the dynamically loaded library in the library, and the dynamic library dependent library is not updated.

There is also a problem with the 0xc000007b startup program: it is likely that the dependent library is in conflict (that is, the dependent library’s version may not be correct)
