Initialization of bean failed； nested exception is java.lang.StackOverflowError

Too many assemblies in mybatis spring mapper cause stackoverflow

It is applicable to idea starting a new SSM project
environment Tomcat deployment
reason: the space size of Tomcat catalina.sh is not configured

terms of settlement

1. Modify the catalina.sh file of Tomcat

Directory: Apache Tomcat \ bin \ Catalina. Sh
self allocated space size
Directory: JDK \ 1.8 \ JRE \ lib \ AMD64 \ JVM. CFG
self allocated space size

2. Easy: modify the current project configuration of idea

two point one

Generally, 2100 variables are enough

  Tomcat startup space configuration

 

-Xms512m -Xmx512m -Xss2m -XX:PermSize=512m -XX:MaxPermSize=1024m

Restart to solve the problem

I am the second configuration. Because there is a configured space allocation on the server, my locally developed tester is simply configured on the idea.

org.thymeleaf.exceptions.TemplateInputException: Error resolving template [XXX]

Error record:

org.thymeleaf.exceptions.TemplateInputException: Error resolving template [currentUserCartItems]

Background: Spring + thymeleaf reports an error

Reason: no @ respontroller or @ ResponseBody annotation is written on the method of data returned by the controller, and the returned data will be converted to JSON format

note: if it is necessary to return page Jump, it is best to add @ ResponseBody annotation on the specific method of data returned, otherwise other controllers cannot jump to the page normally

When idea generates a spring boot project, error: read timed out appears

When using idea to generate spring boot projects, the following occurs: error: read timed out ,

The solution is as follows:

    click file in the upper right corner of idea and select settings in the list. Click settings
    to open the settings box, and select appearance & amp; on the left; Behavior –> System Settings –> HTTP proxy, select auto detect proxy settings on the right, click Check connection below, and fill in in the pop-up box https://start.spring.io , click OK

  solve the problem:

In fact, there are no errors in the code. For example, after using the element UI or iView framework, you will find that some parts of vs code will automatically mark red wavy lines,  

In fact, it is a syntax check problem for vuter. You only need to add it in setting.json  

“vetur.validation.template”: false

Setting method:

 

 

Create Vue cli project and report error command failed: Yarn

Create Vue cli project and report error command failed: Yarn

Solution 1:

Enter C:/users/administrator/in the windows environment

There is a file . Vuerc

Open this file to display

{
“useTaobaoRegistry”: true,
“packageManager”: “yarn”
}

Just manually change the configuration content yarn to NPM to change the package manager when the project is created

Solution 2:

Delete the. Vuerc file. When you create a Vue project for the first time, you will be prompted to select the configuration, and then select NPM.

Solution 3: enter CMD in Win + R to enter the command line interface

Enter command

npm install -g yarn

After success, the problem can be solved by re creating vue-cli4 project.

Error reading file cow.osg: read error (Could not find plugin to read objects from file “cow.osg“.)

reason

I compiled the library with osg3.6.5 on one machine, and then wrote the program. It runs normally, but it is copied to the other machine. The other machine is the library compiled with osg3.7.0, so it causes an error

Osg3.6.5 library

Idea SpringBoot：Error creating bean with name ‘XXXXController‘

Problem Description:

Red when starter starts springboot:

  Error creating bean with name ‘indexController’

Error creating bean named ‘indexcontroller’

Error in bean of ‘sqlsessionfactory’: failed to instantiate bean through factory method

Problem solving:

According to the error report, it can be seen that the mapper layer is not injected and the mapper instance cannot be found. First, check the springboot core configuration file application.yml. In the mybatis configuration structure, the bean is not configured in the custom scan package type aliases package. Just reconfigure it (the package name depends on the individual)
