Abnormal scene
When Java 8 switches to Java 11, there is an error and sun is not found security 。
Problem analysis
Jar package and source code are available. The probability is due to the security policy in the new JDK.
Solution:
In the compiler’s settings -> Build,Execution -> Compiler-> Disable in Java compiler:
Use ‘–release’ option for cross-compilation
Then rebuild
If there is no exception after build, check it again.
The job normally builds success, and then reports asynchronous execution failure, as shown below

3. Caused by: org.jboss.netty.channel.ChannelException: Failed to bind to: /0.0.0.0:20880 Attempt to bind the service to port 20880 of this machine failed
4. Caused by: java.net.BindException: Address already in use: The bind address has already been used
Solution:
application.yaml or application.properties configuration file port from 20880 to 20881 can be modified because I have configured 20880 in other modules, so here again configuration will report a duplicate binding exception ~ ~

Reason: the httppost used does not implement closeable and is not supported. The compiler automatically helps us complete close(), which is not available in httppost. If you want to test the writing method, you can use: closeablehttpclient, bufferedinputstream and so on. Finally, decompile it.

Cause of the problem
MyBatis in the query for select mapping, the return type can be used resultTy, investigation and analysis found that the customer’s program to return the field type is longvarchar, so take the jar package within the tolong method, causing errors.
Solution
Modify the return field type longvarchar to varchar in the program.
Error code
com.highgo.jdbc.util.PSQLException:bad value for long
Problem phenomenon:
Today, I wanted to debug the service on my computer. I found that when calling the interface through the gateway, an error related to Kafka was reported, as follows:
java.net.UnknownHostException: kafkahost
Problem analysis:
It can be seen from the error message that the host named kafkahost cannot be recognized.
By viewing the configuration of a service instance of Kafka cluster configuration on Linux server, you can find:
listeners=PLAINTEXT://kafkahost:0091
This configuration uses the {kafkahost} mentioned in the error message. You can see that this service instance listens to the IP port} kafkahost: 0091; By viewing the/etc/hosts file of the Linux server, you can see:
Kafkahost points to the Linux server IP.
Since I accessed the Kafka service on the Linux server in the native service, I naturally could not resolve to kafkahost. Therefore, you need to add the corresponding configuration in the hosts file of this machine!
Solution:
Find the hosts file path of this machine:
C:\Windows\System32\drivers\etc
Add the following configuration at the end of the file to identify kafkahost as the Linux server IP:
Restart the local service and call the interface again without any error:

analysis
java.Lang.linkageerror this exception is often encountered in applications using multiple classloaders
the reason for this error is the class conflict caused by the cross use of class classes with the same qualified name after being loaded by multiple different classloaders. Classes with the same qualified name belong to different class instances in different classloaders. When loading a class, the JVM needs to load all imported classes. In this case, if there is a class with the same qualified name in the custom classloader as that in the parent classloader, Java. Net will be thrown Lang.LinkageError.
from the error message, you can see that the javax/security/auth/X500/X500 principal class is loaded by the classloader and bootstrapclassloader customized by powermock at the same time.
Solution:
Use @powermockignore to make javassistmockclassloader ignore the loading of javax/security/auth/X500/X500 principal:
@PowerMockIgnore({"javax.security.*"})
