IDEA Import Servlet Package Error [How to Solve]

When we use idea to import packages related to servlets, we sometimes encounter errors, which leads to the problem that servlets cannot recognize. In fact, the reason for the problem is very simple, that is, we can’t find packages related to servlets in JDK

Solution:
1. Find the installation directory of Tomcat, here is C:\Program Files\Apache Software Foundation\Tomcat 8.5\lib (Note: not everyone’s directory is this, need to be based on the actual situation of your computer’s installation directory), find the Servlet-api.jar This file, copy it

2. then go to the JDK installation directory: C:\Program Files\Java\jdk1.8.0_241\jre\lib\ext, find the ext folder, and then copy the Servlet-api.jar file just copied to this folder

3. Back to the idea, the problem is solved, if the idea is still reporting errors, restart the idea refresh

Solution:

Compared with other similar services
it is found that

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
<!--            <version>2.2.7.RELEASE</version>-->
        </dependency>

The version of openfeign is redundant and can be run after being commented out

[Solved] ERROR SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: System memo

During the actual operation of the recommendation system, the following errors occur when executing the featureengineering (Scala) file:
ERROR SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: System memory 259522560 must be at least 471859200

Solution:
1. Click Edit configurations

2 If your setting interface has the following red box, paste the following text directly

-Xms128m -Xms512m -XX:MaxPermSize=300m -ea


3. If not, click Modify options first, then add VM options, as shown in the figure below, and then complete the second step

this problem should be solved.

nested exception is java.lang.StackOverflowError [How to Solve]

The above is the error reported by the endpoint accessing oauth2, mainly because the configuration is not well configured, and the configuration before modification:


    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

Modified configuration:


    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.jdbcAuthentication()
                .dataSource(dataSource)
                .passwordEncoder(new BCryptPasswordEncoder());
    }

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.

Solution:

There are three files in the instance directory

ubuntu03@ubuntu03:~/canal_server/conf/example$ ls -l
total 140
-rw-rw-r-- 1 ubuntu03 ubuntu03 135168 Feb 18 02:11 h2.mv.db
-rw-rw-r-- 1 ubuntu03 ubuntu03 135168 Feb 18 02:11 meta.dat
-rwxrwxr-x 1 ubuntu03 ubuntu03   2106 Feb 17 11:12 instance.properties

Delete h2.mv.db and meta.dat is OK

rm -rf canal_server/conf/example/h2.mv.db 
rm -rf canal_server/conf/example/meta.dat

restart canal-server(canal-deployer)

sh canal_server/bin/restart.sh
