[Solved] Error processing condition on org.springframework.boot.autoconfigure.context.PropertyPlaceholderA

The error information is as follows:

I thought the PropertyPlaceholderAutoConfiguration class didn’t match automatically. After checking, it’s not the problem.

Then by:

Caused by: java.lang.reflect.MalformedParameterizedTypeException: null
	at java.lang.reflect.Method.getGenericReturnType(Method.java:255)
	at org.springframework.core.MethodParameter.getGenericParameterType(MethodParameter.java:419)

Find the problem that may be the type mismatch, go to the breakpoint where the error occurs, and debug:

From the figure, you can see that when redis does the configuration, the type returned is GenericObjectPoolConfig<? >, search the code and find where redis configures the data source.

Defining the return type is indeed GenericObjectPoolConfig<? >, however, clicking GenericObjectPoolConfig jumps to:

I found that the referenced class, surprisingly GenericObjectPoolConfig after not with a generic, so strange!

Could it be a version problem? So, I checked the project dependency tree and found that I was right in guessing that two different versions of commons-pool jars had been introduced.

Checking the code, in version 2.8.0, GenericObjectPoolConfig<T> with generic type is used.

When the problem is found, the jar package of version 2.5.0 is excluded from the POM dependency.

Restart the project, normal.

Vscode configures eslint to solve terminal syntax error

1. Problem scenario

Pull the code from GitHub or build the project with the scaffold Vue cli. The terminal has syntax errors that do not comply with eslint, which is very uncomfortable

2. Solutions

First, install eslint

Second, configure setting

File – & gt; Preferences – & gt; Settings – & gt; Search eslint

Fill in the following configuration code

// By default, vscode has enabled the option to automatically set tabsize based on file type

"editor.detectIndentation": false,

// Reset tabsize

"editor.tabSize": 2,

// # Automatically format each time it is saved

"editor.formatOnSave": true,

// # Fix the code in eslint format every time it saves

"eslint.autoFixOnSave": true,

// Add vue support

"eslint.validate": [

  "javascript",

  "javascriptreact",

  {
    "language": "vue",

    "autoFix": true

  }

],

//  #Let prettier use eslint's code format for checksums

"prettier.eslintIntegration": true,

// # Remove the semicolon at the end of the code

"prettier.semi": false,

// # Use quoted instead of double quotes

"prettier.singleQuote": true,

// # Make a space between the function (name) and the parentheses that follow it No space false

"javascript.format.insertSpaceBeforeFunctionParenthesis": false,

// # Make the js in vue formatted according to the editor's own ts format

"vetur.format.defaultFormatter.js": "vscode-typescript",

"vetur.format.defaultFormatterOptions": {
  "js-beautify-html": {
    "wrap_attributes": "force-aligned"

    // # formatting styles for html code in vue components

  }

},

"window.zoomLevel": 0,

"explorer.confirmDelete": false,

"explorer.confirmDragAndDrop": false,

"editor.renderControlCharacters": true,

"editor.renderWhitespace": "all",

"editor.codeActionsOnSave": {
  "source.fixAll.eslint": true

}

Step 3 open . Eslitrc. JS of the project

Fill in the following configuration code

// https://eslint.org/docs/user-guide/configuring

 

module.exports = {
  root: true,

  parserOptions: {
    parser: 'babel-eslint'

  },

  env: {
    browser: true

  },

  extends: [

    // https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention

    // consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.

    'plugin:vue/essential',

    // https://github.com/standard/standard/blob/master/docs/RULES-en.md

    'standard'

  ],

  // required to lint *.vue files

  plugins: ['vue'],

  // add your custom rules here
  rules: {
    // allow async-await
    'no-console': 'off',
    indent: ['error', 2, { SwitchCase: 1 }],
    semi: ['error', 'always'],
    'space-before-function-paren': [
      'error',
      { anonymous: 'always', named: 'never' }
    ],
    'generator-star-spacing': 'off',
    // allow debugger during development
    'no-debugger': process.env.NODE_ENV === 'production' ?'error' : 'off'
  }

pycharm: Unable to display frame vriables

works fine when you use pycharm to connect to programs on a Linux server. But can not be debugged, debugging time is special card, and variable window variables can not load out

tried to expand the memory of pycharm, but failed.

pycharm website for the solution of the method can effectively solve the: https://blog.jetbrains.com/pycharm/2012/08/gevent-debug-support/

is recorded here:

file-> setting-> python debugger

and then check the box in front of the Gevent compatible.

The PIP installation package was successful but the import failed

the problem I ran into was not installing the package in the virtual environment, taking the jieba package as an example

enter python in the virtual environment, and then you can import the package. We thought it was packaged, but it was actually installed in the basic environment.

When

USES conda list to view the packages in the current environment, there is no jieba package. 

conda list

forgot the screenshot,,,,

so you need to install jieba using the PIP of the virtual environment.

after confirming wrapping in a virtual environment, switching to a python environment cannot be done by simply typing python commands. Instead, use virtual environment Python, just like the previous PIP.

for example, you now have two files, test.py and test.sh.

test.py

import torch
print(torch.__version__)

test.sh

python test.py

you can see that the PIP version printed in the virtual environment is different from the one printed in the bash script.

so while I installed jieba in the pytorch1.4 environment, the command I used directly was not python in pytorch1.4, but python in the base environment.

summary:

  1. whether the package to the environment
  2. used the python interpreter is not the package environment interpreter

there are a lot of ways to do it online, so this is a supplement to what’s possible.
