Eureka Build Error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name

Error reported when setting up Eureka server:

It means creating a bean named “bootstrap importselectorconfiguration”. Error: bean initialization failed;

2. Inspection items

1. Configuration file (no problem)

2. Eureka server dependency (no problem)

3. Start class check (no problem)

4. Springboot and spring cloud (problem) — the version is too high

Many blogs talk about reducing the springboot dependency version. I tried to reduce the springboot dependency version only, but still an error will be reported
it may be that the boot version is incompatible with the cloud version, and I don’t know the exact problem. I just guess. If you know the reason, you can explain it. Thank you

3. Solution

Change the dependent version as shown in the figure below

Error running ‘Android Debugger (-1)‘ [How to Solve]

The Android studio attach debugger suddenly fails. Read the event log and report an error

2: 10 PM can’t bind to local – 1 for debugger

2: 10 PM error running ‘Android debugger (- 1)’: unknown error

2: 10 PM error running ‘Android debugger (- 1)’
invalid argument: argument invalid
[port]

There are similar port occupancy and other errors on the Internet, but those are basically a specific port, which is directly – 1 port. At first, I wanted to change the debugger’s port in preference to use existing manually managed server, and specify a port, so I couldn’t connect directly.

After that, I thought it was because preview and the official version were installed at the same time, and then I reinstalled Android studio.

Finally, it was solved. It turned out that the host file needs to map localhost to 127.0.0.1

127.0.0.1       localhost

Zlib.error: error – 3 while decompressing: incorrect header check in Python

As shown in the following code:

b64_encoded_bytes = base64.b64encode(zlib.compress(b'abcde'))
encoded_bytes_representation = str(b64_encoded_bytes)  # this the cause
zlib.decompress(base64.b64decode(encoded_bytes_representation))

Zlib.decopress error

zlib.error: Error -3 while decompressing: incorrect header check

The reason for this is the use of the str() method
The description of the str() method in the python3 documentation.
If neither encoding nor errors is given, str(object) returns object.str(), which is the “informal” or nicely printable string representation of object. For string objects, this is the string itself. If object does not have a str() method, then str() falls back to returning repr(object).
The str() method only serves to put the

b'eJxLTEpOSQUABcgB8A=='

Converted to

"b'eJxLTEpOSQUABcgB8A=='"

The correct conversion should be to

"eJxLTEpOSQUABcgB8A=="

The solution is to specify the encoding method in the str() method

str(b64_encoded_bytes, 'utf-8')

[Solved] Vue unit test syntax error: unexpected token ‘export‘

Paste error information to facilitate search engines to find similar errors

Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

    D:\123\vue3-pro\h5-editor\node_modules\[email protected]@lodash-es\lodash.js:10
    export { default as add } from './add.js';
    ^^^^^^

    SyntaxError: Unexpected token 'export'

Solution

After checking online for a long time, I finally found the only way to solve my problem. If the common methods on the Internet are useless, friends can try

According to the reply to the question, you can configure the following in jest. Config. JS 

"transformIgnorePatterns": [
  "<rootDir>/node_modules/(?!lodash-es)"

PIKA trouble02 — (error) ERR Syntax error, try CLIENT (LIST [order by [addr|idle]| KILL ip:port)

  1. Problem description

Redis was originally used, but now Pika is used. Springboot version 2.1.8 is used. ClientName is configured inside. There is no problem when starting, but the following exception information will be reported when using:

org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool] with root cause

redis.clients.jedis.exceptions.JedisDataException: ERR Syntax error, try CLIENT (LIST [order by [addr|idle]| KILL ip:port)

    @Bean
    public RedisConnectionFactory connectionFactory(RedisProperties redisProperties) {

        JedisClientConfiguration clientConfig = JedisClientConfiguration.builder()
                .clientName("zcx")
                .usePooling().poolConfig(getGenericObjectJedisPoolConfig(redisProperties)).and().readTimeout(redisProperties.getTimeout())
                .build();

        RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration(redisProperties.getHost());
        configuration.setPort(redisProperties.getPort());
        configuration.setPassword(RedisPassword.of(redisProperties.getPassword()));

        return new JedisConnectionFactory(configuration, clientConfig);
    }

  2. Solution

After searching, it is caused by the ClientName field. Just remove the ClientName configuration. The problem is found as follows:

Call creation connection in class GenericObjectPool

private PooledObject<T> create() throws Exception {
        ...

        final PooledObject<T> p;
        try {
            p = factory.makeObject();
        } catch (final Throwable e) {
            createCount.decrementAndGet();
            throw e;
        } finally {
            synchronized (makeObjectCountLock) {
                makeObjectCount--;
                makeObjectCountLock.notifyAll();
            }
        }
}

The client setname “zcx” command is called in the JedisFactory class, and an exception is thrown.

@Override
  public PooledObject<Jedis> makeObject() throws Exception {
    final HostAndPort hostAndPort = this.hostAndPort.get();
    final Jedis jedis = new Jedis(hostAndPort.getHost(), hostAndPort.getPort(), connectionTimeout,
        soTimeout, ssl, sslSocketFactory, sslParameters, hostnameVerifier);

    try {
      jedis.connect();
      if (password != null) {
        jedis.auth(password);
      }
      if (database != 0) {
        jedis.select(database);
      }
      if (clientName != null) {
        jedis.clientSetname(clientName);
      }
    } catch (JedisException je) {
      jedis.close();
      throw je;
    }

In the final analysis, pika does not support the client setname command, so when creating a connection, it cannot obtain the connection and report that the command is not supported

[Solved] WordPress Upgrade PHP 5.6 to 7.x Fatal error: Uncaught Error: Call to undefined function mysql_connect()

Error reporting when upgrading PHP version 5.6 to 7. X under WordPress (resolved)

Cause of event:

When using WordPress, the theme needs to be upgraded. The PHP version required for viewing the theme is 7.1+

When the website is not backed up, the PHP version is changed to 7.2, which directly leads to the website error

Fatal error: Uncaught Error: Call to undefined function mysql_ connect()

Check many online tutorials, which are MySQL in wp-db.php_Change connect() to mysqli_Connect(), no result

At first, I thought that the database reported an error, checked the database in detail, wrote checkdb.php, locally connected to the database, and checked that the database server was running well

Solution:

Set define ('wp_use_ext_mysql ', true) in wp-config.php delete

error explanation:

define('WP_USE_EXT_MYSQL',true);

define(‘WP_USE_EXT_MYSQL’, true); Force WP to use MySQL by default instead of MySQL Li
so please delete this line and the problem should be solved.

Otherwise, you can check nd in the PHP 7 configuration_Mysqli extension, and disable mysqli extension – > Select the PHP version.

Solution:

1. first look at whether you have used the ResultMap to define the returned result set, if so, look at your configuration of the xmlSQL statement mapping the return set result type is resultType or resultMap type, if it is the resultType type, then it is right, change the resultType to resultMap type, it should be right. 2.
The reason is: when you use the custom resultMap for the returned result set, you did not change the SQL statement in the xml file of the resultType to resultMap, resulting in not finding the id of the result set of your custom resultMap, that is, Cause: java.lang. ClassNotFoundException: Cannot find class: <here is the id name of your custom resultMap>.

    1. when the controller layer finished processing the request and returned, it did not use @Restcontroller or @ResponseBody but returned a non JSON format
    1. in this case, the returned data thymeleaf template cannot be parsed and an error is directly reported. I officially reported an error for this reason

Solution: you can change @Controller to @Restcontroller, but you should pay attention to whether other methods return HTML pages, which will result in string instead of page; The best way is to add a @ResponseBody to the requested method.

      1. when the corresponding method of your controller layer returns the HTML path and name, add an additional /

For example, return “/ index”. If this/causes an error, the solution is to remove the/in front of the return, such as return “/ index”.

        1. in the process of using springboot, if thymeleaf is used as the template file, the HTML format must be strict HTML5 format and there must be an end tag, otherwise an error will be reported</ ol>

The solution is as follows:
add the following configuration in application.yml

spring.thymeleaf.content-type: text/html 
spring.thymeleaf.cache: false 
spring.thymeleaf.mode: LEGACYHTML5

Add the following dependencies in pom.xml

<dependency> 
<groupId>net.sourceforge.nekohtml</groupId> 
<artifactId>nekohtml</artifactId> 
<version>1.9.22</version> 
</dependency>

The path of the

          1. resource file has been modified. If your other requests return normally, you can ignore this one

Solution: add in the of pom.xml file

<resource>
 <directory>src/main/resources</directory>
</resource>
