[Solved] Docker Startup Error: OCI runtime create failed container_linux.go380 starting container process

Docker startup error

response from daemon: OCI runtime create failed: container_ linux. go:380: starting container process

The reason is that a startup script does not have execution permission

Solution:

Give the startup script execution permission: chmod +x entrypoint.sh

1. The container startup script defined by docker-compose is entrypoint: ./entrypoint.sh, this script must have executable permissions on the host
2. For images created by Dockerfile, the startup scripts in CMD also need to have execution permissions

[Solved] ClickHouse Error: Code: 62. DB::Exception: Syntax error (Multi-statements are not allowed): fai

1. Preparation

First, I need to create a table and write the corresponding fields in it:

create table t_order_mt(
 id UInt32,
 sku_id String,
 total_amount Decimal(16,2),
 create_time Datetime
) engine =MergeTree
 partition by toYYYYMMDD(create_time)
 primary key (id)
 order by (id,sku_id);

Next, you need to insert the corresponding data into it:

insert into t_order_mt values
(101,'sku_001',1000.00,'2020-06-01 12:00:00') ,
(102,'sku_002',2000.00,'2020-06-01 11:00:00'),
(102,'sku_004',2500.00,'2020-06-01 12:00:00'),
(102,'sku_002',2000.00,'2020-06-01 13:00:00'),
(102,'sku_002',12000.00,'2020-06-01 13:00:00'),
(102,'sku_002',600.00,'2020-06-02 12:00:00');

2. Error display

When I execute select * from table_name, the following problems may occur:

Code: 62. DB::Exception: Syntax error (Multi-statements are not allowed): failed at position 54 (end of query) (line 1, col 54): ;


 FORMAT JSON . . (SYNTAX_ERROR) (version 21.11.6.7 (official build))

3. Solution

You only need to end the sentence after the corresponding sentence; Change to:

select * from t_order_mt;;

Results

JAVA Error: Error attempting to get column ‘XXX’ from result set. Cause java.sql.

The entity class in Java uses the LocalDateTime type
Convert error: Error attempting to get column ‘XXX’ from result set. Cause: java.sql.

The solution is the simplest:
Switch the version number of com.alibaba to 1.1.22

   <dependency>
         <groupId>com.alibaba</groupId>
         <artifactId>druid-spring-boot-starter</artifactId>
         <version>1.1.22</version>

Solution:
1. Check the JDK of project（Ctrl+Alt+shift+S）
File ->Project Structure->Project Settings ->Project

2. Check the JDK of project（Ctrl+Alt+shift+S）
File ->Project Structure->Project Settings -> Modules -> (the name you need to modify) -> Sources ->

3. Check the configuration of Java
File ->Setting ->Build,Execution,Deployment -> Compiler -> Java Compiler

If the above three steps still fail

When the configured Tomcat starts a new project, it stops automatically half way through.

After checking the configuration of artifacts, it turns out that the path is wrong:

Note the output directory:

After configuring artifacts, remember to add dependencies in Tomcat:

Solution: finally, it is found that there is a conflict between the versions of sprngboot and springcloud

I’m using these two versions: springboot2.2.0RELEASE and spring-cloud的Greenwich.SR2

Using springboot2.2.0 is 119 jars package.

Finally, use springboot 2 1.6 is 116 jar packages

DevTools failed to load SourceMap Could not load content [Solved]

DevTools failed to load SourceMap: Could not load content

What it means here is that the dev tool failed to load the source mapping: it couldn’t load the content. The focus is on the part after the for.
The hint I encountered was something like this

DevTools failed to load SourceMap: Could not load content for chrome extension://ncennffkjdiamlpmcbajkmaiiiddgioo/js/xl-content.js.map

That is, the part of the chrome extension tool, the mapping failed to load successfully.

After inquiry, the latter link is caused by the opening of the Xunlei extension tool in chrome, but it does not affect normal operation, you can also consider disabling the tool in the extension program

Gradle Compile Error: compileJava FAILED [How to Solve]

When using gradle project, the following situations occur during the process of building a file:

> Task :compileJava
/home/user_1/idea-program/avro-car-sensor-simulator-master/src/main/java/com/hivemq/CarDataPayloadGenerator.java:7: error: cannot access PluginPayloadGenerator
import com.hivemq.simulator.plugin.sdk.load.generators.PluginPayloadGenerator;
                                                      ^
  bad class file: /home/user_1/idea-program/avro-car-sensor-simulator-master/device-simulator-plugin-sdk-1.0.0.jar(com/hivemq/simulator/plugin/sdk/load/generators/PluginPayloadGenerator.class)
    class file has wrong version 55.0, should be 52.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.

> Task :compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

According to the above error conditions:

“bad class file: /home/user_1/idea-program/avro-car-sensor-simulator-master/device-simulator-plugin-sdk-1.0.0.jar(com/hivemq/simulator/plugin/sdk/load/generators/PluginPayloadGenerator.class)

class file has wrong version 55.0, should be 52.0

Please remove or make sure it appears in the correct subdirectory of the classpath.”

It is possible to know that the problem occurs in the idea-program/avro-car-sensor-simulator-master/device-simulator-plugin-sdk-1.0.0.jar, which requires version 55, while the current environment is version 52.
(Reason for the error: running a class file compiled with a JDK of 11 using a JRE with a JDK of 8)

The corresponding version of Java is as follows:

ava SE 13 = 57,
Java SE 12 = 56,
Java SE 11 = 55,
Java SE 10 = 54,
Java SE 9 = 53,
Java SE 8 = 52,
Java SE 7 = 51,
Java SE 6.0 = 50,
Java SE 5.0 = 49,
JDK 1.4 = 48,
JDK 1.3 = 47,
JDK 1.2 = 46,
JDK 1.1 = 45

After configuring java11, try again and compile successfully
