1. Error in adding Maven project in idea: Java: package javax Servlet does not exist. As shown in the figure:
2. Solution
1. In file — > Project Structure –> Make changes in modules
2. Select dependencies in modules and click + — > Jars or directories to add
3. Select the local Tomcat installation path, go to the lib folder and select: jsp-api.jar and servlet-ap.jar, then click OK, we can see two more packages, click Apply OK, the following figure.
4. Redeploy the project to run successfully.
The following error is reported when the test case is started:
Command line is too long. Shorten command line for XXXXXXTest. or also for JUnit default configuration?
Error running ‘XXXXXXXXXX.rmLogRecordOverDue’:
Error:Command line is too long
Solution 1:
Modify workspace.xml file, add the following in <component name="PropertiesComponent">:
<property name="dynamic.classpath" value="true" />
It is also possible that the configuration file cannot be modified and will be automatically deleted after modification, so you can see solution 2
Solution 2:
Modify the startup scheme of local test cases as jar
select
finally select jar mainfest to start

In the error message, you can know that there is an error when injecting the bean of usermapper
Error reason:
Mapper package scan path error on springboot boot start class
package com.cy;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("mapper")
//mapperScan annotation to automatically load all mapper interface files when the project starts
public class StoreApplication {
public static void main(String[] args) {
SpringApplication.run(StoreApplication.class, args);
}
}Solution: Modify @MapperScan(“mapper”) to the correct path.
Phenomenon:
413 is returned in the file upload interface
Now look at the requestbody inside Content-Length: 1438551 this is no problem, the server will use the default configuration in the absence of separate configuration, nginx default request body limit size 1M, so you need to adjust the nginx limit size.
Windows opens pycharm and reports an error: failed to load JVM DLL pycharmjbrinserverjvm.dll
JDK is downloaded and installed successfully, and environment variables are configured successfully
solution: Pycharm can be run as an administrator
Other methods are useless
1. Install Microsoft Visual C+ + 2010 redistributable package -> “there is a 2015 version in the computer
2. JDK version problem ->” verify that it is correct, and still report an error after downloading other configurations
3. Reinstall pycharm after installing JDK – “useless
4. Restart the computer -” useless

#You need to configure the time it takes for the ribbon to read the available resources from the server after establishing a connection #ReadTimeout=60000 # Time to establish a connection, applicable to the time it takes for both ends to connect if the network condition is normal #ribbon.ConnectTimeout=60000
Why does this happen? Later, it was found that thread.Sleep(3000) was added when providing services.
Comment out thread.Sleep (3000), there is no need to configure ribbon connection and read timeout.
@RequestMapping("/getProductAll")
public List<String> getProductAll() throws InterruptedException {
Thread.sleep(3000);
count++;
List<String> listProduct = new ArrayList<String>();
listProduct.add("notebook3");
listProduct.add("pen");
listProduct.add("bike");
listProduct.add(serverPort);
listProduct.add(String.valueOf(count));
return listProduct;
}Take a closer look at the ribbon Code:
DefaultClientConfigImpl in com.netflix.client.config of the ribbon-core-2.3.0.jar
//CommonClientConfigKey.ReadTimeout default is 5000
public int getDefaultReadTimeout() {
return 5000;
}
//CommonClientConfigKey.ConnectTimeout default is 2000
public int getDefaultConnectTimeout() {
return 2000;
}After modify the service provider code thread.Sleep (500), the system can use zuul without adding configuration
