Error creating bean with name ‘adminMapper‘ Injection of resource dependencies failed

Project scenario:

springboot project, unable to create bean object and inject dependency

Problem Description:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'adminService': 
 Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 
'adminMapper' defined in file [E:\IdeaCode\toyrentalplatform\target\classes\cn\gestwr\toy\dao\AdminMapper.class]: Unsatisfied dependency expressed through bean property 
'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException:

Cause analysis:

It is the configuration file application Properties

Solution:

the configuration options of the configuration file are wrong, for example, the following configuration is added and an error is reported

mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

In the properties file, the color of this configuration is different from that of other configurations. The correct one is light green

Note the format of the YML configuration file

thymeleaf Error: An error happened during template parsing Cannot render error page for request

By looking at the front-end html code, there is a syntax error
Although I have commented out the error code
but the use of <! –> can only keep the browser from displaying it, but it can’t keep the thymeleaf template engine from parsing it.
I should have used the thymeleaf comment syntax <! –/* */–> to comment it out

The error message is as follows.

[Solved] rocketmq Startup Error: Error: Could not create the Java Virtual Machine.

Java HotSpot ™ 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated

It may be a JDK version problem

jdk1.8 is OK
if you want to use a higher version, such as jdk11

Windows:
Modify bin\runserver.cmd
Linux:
Modify bin\runserver.sh
before modification:

set "JAVA_OPT=%JAVA_OPT% -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:SoftRefLRUPolicyMSPerMB=0 -XX:+CMSClassUnloadingEnabled -XX:SurvivorRatio=8 -XX:-UseParNewGC"

[Solved] Error:java: Compilation failed: internal java compiler error

1, view the project’s jdk (Ctrl+Alt+shift+S)
File ->Project Structure->Project Settings ->Project

2. view the jdk of the project (Ctrl+Alt+shift+S)
File ->Project Structure->Project Settings -> Modules -> (the name of the project needs to be modified) -> Sources ->

3. View Java configuration in idea
File ->Setting ->Build,Execution,Deployment -> Compiler -> Java Compiler

If the above three steps still fail
Clear IDEA cache Restart IDEA
File->Invalidate Caches/Restart

[Solved] IntelliJ IDEA Compile Groovy Error: GroovyRuntimeException: This script or class could not be run.

1. Error record

function

class Student1 {
}

Groovy code will report an error;

 

Error message:

groovy.lang.GroovyRuntimeException: This script or class could not be run.
It should either:
- have a main method,
- be a JUnit test or extend GroovyTestCase,
- implement the Runnable interface,
- or be compatible with a registered script runner. Known runners:
  * <none>

 

2. Problem analysis

Only groovy code that meets the following requirements can run:

With main function

test case, used as JUnit test or extended GroovyTestCase

Thread related and implements the runnable interface
It is compatible with the registered script running program

Groovy code in other cases cannot be run;

[Solved] Idea 2021.3 Maven 3.8.1 Error: Blocked mirror for repositories

The blocked mirror for repositories problem is due to Maven 3 8.1 from the beginning, the HTTP connection is blocked in the configuration file by default
idea has the following solutions to solve this problem
1. Replace the use of Maven for version 3.6.3 https://dlcdn.apache.org/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.zip

2. When idea loads external configuration files, it will load the settings.xml in the \plugins\maven\lib\maven3\conf folder in the installation directory first, comment the file

<mirror>
      <id>maven-default-http-blocker</id>
      <mirrorOf>external:http:*</mirrorOf>
      <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
      <url>http://0.0.0.0/</url>
      <blocked>true</blocked>
    </mirror>

It will take effect
