[Download Files Error] HttpMessageNotWritableException IllegalStateException: COMPLETED

When you click to download a file, the error prompt is mainly reported. You can still download it, but since an error is thrown, go to find it. Finally, I found an error in the operation…

org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver : Failure while trying to resolve exception [org.springframework.http.converter.HttpMessageNotWritableException]
java.lang.IllegalStateException: COMPLETED

org.springframework.http.converter.HttpMessageNotWritableException: No converter for [class com..filepreview.entity.DataPackage] with preset Content-Type 'application/x-msdownload;charset=utf-8'

See the main tips:

Request processing failed; The nested exception is org.springframework.http.converter.httpmessagenotwritableexception: there is no converter for [class com. Filepreview. Entity. Datapackage] whose default content type is “applicationx msdownload”; Character set = UTF-8 ‘

So I see the keyword: datapackage, which is the encapsulated data return

The download file I thought of was actually a stream transmission, so I deleted this package and changed the method to void type

Abnormal output:

Normal after modification:

Git Clone Error: gnutls_handshake() failed: Decryption has failed [How to Solve]

The system is Ubuntu (kylin) 20.04 and git version 2.25.

Clone error

The following error is reported when the GIT clone the warehouse on the GitHub,

fatal: cannot access' https://github.com/xxx/yyy.git ': gnutls_handshake() failed: Decryption has failed.

Repeated many times.

Simple try

Most of the failures of GIT clone are network problems, especially when using GitHub.

First try the proxy, http_ proxy，https_ Proxy, GIT config, http.proxy and other commonly used methods have been tried, and even the hack method of proxychains has been tried, but the results are not good. Instant confidence is gone.

Things are different this time.

 

Recompile

There are two methods to recompile. One is to use the script provided by the boss [1]. The second is to use the source code in apt to compile and package DEB by myself. I refer to [2] [3] two tutorials. The general method is

1. Open source

2. Get the source code apt source git , and modify libcurl4 gnutls dev in Debian/control file to libcurl4 OpenSSL dev.

3. Install the compilation environment, sudo apt get build dep git

4. Compile dpkg buildpackage - B, after a long compilation and a complete set of tests, several Debs are finally packaged. (there are still a few mistakes, regardless)

5. Install the packaged DEB, dpkg - I Git_xxx.deb

Finally, it’s done. Git clone is very slow, but no decryption error is reported. The proxy is set successfully. The last step, apt mark hold git, prevents git from being automatically updated. That’s it.

Postscript

The specific cause of the error has not been thoroughly studied, and it looks more complex. Therefore, a workaround was taken and recorded here. Thank all the original authors.

First update

1. It has been verified that git in livecd (Ubuntu kylin 20.04 Pro) still has this bug. In Galaxy Kirin V10 Sp1 livecd, the installed git also has this bug

2. The GIT of desktop (Intel processor) virtual machine and livecd is normal, so it is suspected that it is a hardware problem

3. Gitee does not have this problem

It is speculated that it is a hardware problem, or even a problem with the CPU instruction set. The bottom layer of TLS uses AES algorithm, and there are related instruction sets in CPU. Gitee has no problem, probably because it uses TLS 1.2 and GitHub is TLS 1.3.

[Solved] string(81) “SQLSTATE[HY000]: General error: 1364 Field ‘content’ doesn’t have a default value”

reason

MySQL stipulates that default values are not allowed for blob, text, geometry and JSON data types. In this example, the content field is not set with a default value. After analysis, it is determined whether it is the reason for not null, so the content field is set to null

Solution:

Delete not null in the table creation statement

Error: Can’t walk dependency graph: Cannot find module ‘@popperjs/core’ from ‘node_modules\bootstrap\dist\js\bootstrap.esm.js’

required by D:\pangu\bpmn-js\bpm_editor\node_modules\bootstrap\dist\js\bootstrap.esm.js

When using webpack to package bootstrap 4 and 5, you need to install popper.js manually

npm install @popperjs/core -D

Microsoft. Ace. OLEDB. 12.0 error reporting solution

Reference @ “provider = Microsoft. Ace. OLEDB. 12.0; data source =” + Sourcefile + “;”;

When the server reports this error: the ‘Microsoft. Ace. OLEDB. 12.0’ provider is not registered on the local machine

Solution: OLEDB does not support 64 bits. The server should install 32 bits instead of 64 bits https://www.microsoft.com/en-us/download/confirmation.aspx?id=13255
