[Solved] Vite2 Error: Unknown variable dynamic import

When the project is packaged and deployed with vite, it is found that some page resources cannot be obtained after deployment. The error is as follows:

Solution:

Replace

function getViews(path) {
  return () => import('../' + path + '.vue')
}

with

function getViews(path) {
  // First get all the addresses of the components you need to route dynamically
  let modules = import.meta.glob('. /*/*.vue')
  // Then fetch them like this when dynamically routing
  return modules['../' + path + '.vue']
}

The reason for the error is that there is an error in dynamic route acquisition.

Failure to find … was cached in the local repository, resolution will not be reattempted until the update interval of public has elapsed or updates are forced

When I packaged the project, I reported an error:

 

 

Failure to find com.st:oscarJDBC16:pom:1.0.0 in http://maven.aliyun.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of public has elapsed or updates are forced

 

In order to solve this problem, a lot of information was consulted as follows:

1,

Go to your own .m2 folder and delete all the xxx.lastUpdated files, run maven again, ok!

Or add the -U parameter when using maven, you can ignore xxx.lastUpdated..

Here, a simple investigation is not caused by this reason

2,

Change the version, or change the source to try

I’ve changed it several times, but it still gives an error

3,

Added updatePolicy property to release or snapshots version of repository, where updatePolicy can be set to “always”, “daily” (default), “interval:XXX” (minutes) or “never”

<repositories>
    <repository>
      <id>io.spring.repo.maven.release</id>
      <url>http://repo.spring.io/release/</url>
      <releases>
        <enabled>true</enabled>
        <updatePolicy>always</updatePolicy>
      </releases>
      <snapshots><enabled>false</enabled></snapshots>
    </repository>
  </repositories>

still error

 

final solution

previous pom configuration

[Solved] IDEA Unboxing of ‘stringRedisTemplate.hasKey(xx)’ may produce ‘NullPointerException’

Question details

Yellow warning when using stringRedisTemplate.hasKey(**)

Warning message: IDEA Unboxing of ‘stringRedisTemplate.hasKey(xx)’ may produce ‘NullPointerException’ warning

Possible null pointer exception when unboxing

Look through the hasKey source code

Looking at the hasKey source code, the hasKey method returns an object wrapper, but using it inside the if condition implicitly unboxes it (ie, converts the result of the call to the original value). If for some reason the hasKey method might return null, an error will occur. For security, you can check if the key exists by following the steps below

solution:

if ( Boolean.TRUE.equals ( redisTemplate.hasKey ( XXXX)) { }

The same is true for other return wrapper types Boolean

Springboot Import Error: Cannot resolve org.springframework.boot:spring-boot-autoconfigure:2.6.2

Leave a reply

maven import error

Cannot resolve org.springframework.boot:spring-boot-autoconfigure:2.6.2

 

Solution 1:

Delete the package corresponding to the local maven and download it again

 

Solution 2:

It may be a springboot version problem, lower the version (2.6.2 can’t be used before. Just change to 2.5.7)

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version> 2.5.7 </version>
        <relativePath/> <!-- lookup parent from repository -->
