[Solved] Swagger Startup Error: Failed to start bean ‘documentationPluginsBootstrapper‘

Start swagger in the springboot project. If the following error is reported, two solutions can be adopted:

org.springframework.context.ApplicationContextException: Failed to start bean ‘documentationPluginsBootstrapper’; nested exception is java.lang.NullPointerException

This error is caused by the mismatch between SpringBoot version and Swagger version, the blogger Swagger and Swagger-UI are using Springfox 2.9.2, SpringBoot is automatically provided in Idea when created 2.6.2, Springfox uses path matching based on AntPathMatcher, while Spring Boot 2.6.X uses PathPatternMatcher, the two solutions are as follows:

1. Modify the version of springboot to use the earlier version to solve this problem;

2. Add configuration to YML configuration file: ant_path_matcherspring: mvc: pathmatch: matching-strategy: ant_path_matcher.

[Solved] PyMOL install caver3 error: Unable to initialize plugin ‘Caver3’ (pmg_tk.startup.Caver3).

Plugin“Caver3”has been installed but initialization failed
/Unable to initialize plugin ‘Caver3’ (pmg_tk.startup.Caver3).

Solution:

PyMOL>import pmg_tk.startup.Caver3
Traceback (most recent call last):
  File "D:\ProgramData\Anaconda3\Lib\site-packages\pmg_tk\startup\Caver3\__init__.py", line 25, in <module>
    import pmw
ModuleNotFoundError: No module named 'pmw'

Download PMW module

Method 1:

conda install -c conda-forge pmw

Method 2:

get into https://anaconda.org/conda-forge/pmw Click files to download the PMW compressed package

conda install {the package you need to download}

Enter PyMOL>import pmg_tk.startup.Caver3won’t be wrong

How to Solve cv2.applyColorMap Error

You need to convert the image to 255 and uint8, and then turn back.

        real_image = cv2.cvtColor(real_image,cv2.COLOR_GRAY2RGB)
        real_image = cv2.resize(real_image,(256,256))
        real_image *= 255
        real_image = real_image.astype(np.uint8)
        real_image = cv2.applyColorMap(real_image, cv2.COLORMAP_HOT)
        real_image = np.asarray(real_image/255, dtype=np.float32)

[Solved] IDEA error: sun.security.pkcs not found

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.

    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 ~ ~

Solution

1. Change the version number of springboot to be compatible with spring cloud, and change 2.6.2 to 2.3.1.RELEASE

    <groupId>com.yg</groupId>
    <artifactId>zipkinServer</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>
