The reason for this problem is: springboot2.6.x and the previous version use PATH_PATTERN_PARSER by default, while knife4j’s springfox uses ANT_PATH_MATCHER. Springboot’s yml file configures url matching rules

Error: Error building SqlSession [How to Solve]

The above error occurred:

Copy the XML file in Dao/mapper to the corresponding location of the test class in the target folder. If it runs successfully, delete it, and follow the steps below. (this XML file may be under other packages)

Comparison before and after copying:

Step ①: ensure that the path of the test class is the same as that of the corresponding class in main.

Step 2: view the XML file of your own resources & lt; mappers> Whether the path in is correct (note that slashes are used instead of dots)

Step ③: check whether the path behind the namespace in the XML file of your Dao/mapper package is correct. (this XML file can be under other packages)

Step ④: in your own POM Add the following code to XML, refresh Maven or restart idea. (because the Maven project contract is greater than the configuration, idea will not load the resource files in the Java source directory into the project.)

<!--Configure resources in build to prevent our resource export from failing -->
<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>

If it is the above error: change the UTF-8 in your XML file to utf8 and run it again.

[Solved] Configuration Error: deployment source ‘xxx:war‘ is not valid

1. Error reporting

2. Cause

The latest artifact is not updated in the Tomcat configuration in the idea configuration.

3. Solution

1. Edit configuration

2. Click deployment to see that war is red. Click the ‘-‘ sign on the right to delete the old war package

3. Add a new artifact

4. OK.

[Solved] Idea 2020 uses SVN error: ‘C: \ program’ is not an internal or external command

Because there are spaces in the configured SVN path, the spaces in the middle are not recognized;

Method II:

Replace [C:\program files\TortoiseSVN\bin\SVN.Exe] with [C:\progra ~ 1\TortoiseSVN\bin]

[Solved] IntelliJ idea error: error: Java does not support release 5

Method 1

1. Confirm to configure Maven

Find the path in Maven home path and find the Maven address \ conf \ setting xml

Select your own JDK version

<profile>
      <id>development</id>
      <activation>
        <jdk>1.8</jdk>
        <activeByDefault>true</activeByDefault>

        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
      </properties>
    </profile>

Restart idea

Method 2

In project POM Specify the JDK version in the XML file
