JSP page not rendering with Spring Boot in Spring Tool Suite IDE - spring

I ended up getting this log as a result of running my Spring Boot App with a jsp.
2017-12-29 13:30:52.412 WARN 12631 --- [nio-8080-exec-2]

If your application is running on WebSphere Application Server you may
be able to resolve this problem by setting
com.ibm.ws.webcontainer.invokeFlushAfterService to false
It's evident that in Spring Boot, manual configuration is not needed. So, how should I fix this error?
I am clueless how to fix. I configured the jsp resolver in application.properties.
spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp
I have tomcat-embedded-jasper in the pom.xml.

Hilla not starting Vite - what am I missing?

I have created a hilla app using this:
npx #vaadin/cli init --hilla --auth hilla-with-auth
Works fine!
Now I am trying to add that to an existing spring boot application, but I am having issues with Vite not starting as it should. No exception. No help in the debug output.
I have added:
relevant files in the root (package.json, vite.config.ts, etc.)
vaadin-featureflags.properties in resources folder
hilla dependencies in pom.xml as well as the build plugin
hill annotations to my application class (#Theme, #PWA) and made it extends SpringBootServletInitializer implements AppShellConfigurator
But even if everything seems to be initialized correctly, Vite does not start. Can anyone guide me in the right direction?
This is the most relevant output log:

Spring cloud config server git connection issues

I see issues in the Spring cloud config server (Springboot) logs when connecting to the repo where configs are stored. I'm not sure if it's unable to clone because of credentials or something else (git-upload-pack not permitted). Any pointers to this would be great.

Github token needs to be passed as username which I was configuring against the password property for the spring boot app. The password property needs to be left empty and the Github-token needs to be assigned to the username like below-
spring.cloud.config.server.git.username=asdfasdxxxxxxxyssssysysyssysy
spring.cloud.config.server.git.password=
Token authentication requirements are necesary for Git operations, see this link for more info.:
https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/
Try to add .git in the end of the URI in app.properties
spring.cloud.config.server.git.uri=https://github.sdf.sdasdf.asdf.com/asdf/asdf-configs.git

Spring Framework: mvc:resources does not work

In my Spring Web Application project I've already configured an mvc:resources tag in order to exclude CSS, JS, images ... from DispatcherServlet mapping
Now I need to exclude also a foobar.txt and is placed under /webapp directory like the other static resources but ... It doesn't work.
Here my code snippet
<mvc:resources mapping="/assets/**" location="/assets/" />
<mvc:resources mapping="/foobar.txt" location="/foobar.txt" />
my folder structure is:
/webapp
/webapp/assets
/webapp/foobar.txt
/webapp/...
It's seems like the the first mvc:resources tag (assets) works but the second one (version.txt) doesn't.
I get a 404 page.
These are the difference in console log.

The weird thing is that in another similar project same configuration works without problems.
Thanks in advance for your support.
Try below configuration.
<mvc:resources location="/", mapping="/resources/**"/>
OR if you want to give classpath for a particular location use below.
<mvc:resources location="/, classpath:/META-INF/web-resources/" mapping="/resources/**"/>
Try this configuration.
<mvc:resources mapping="/resources/**" location="/resources/" />
I don't why, but sometimes it works. you can give a try.

static file not loading in spring boot for web-secure-jdbc

I am using spring boot web secure jdbc sample spring-boot-sample-web-secure-jdbc and want to modify it to load static html files (no template like thymeleaf or jsp needed). I have tried putting the html files under src/main/resources but they are not loading.
I noticed that static file example in samples spring-boot-sample-web-static inherits SpringBootServletInitializer for main class while web secure jdbc use WebMvcConfigurerAdapter. I suppose there might be some more configuration needed to make it work them. Below is my dir tree:
src/main/java/hello/MyController.java
src/main/resources/backupshell.html
src/main/resources/myscripts.js
After moving resources to src/main/resources/resources direct url load works fine but via request url mapping as below is not loading:
#RequestMapping("/admin")
//#ResponseBody
String admin() {
//return "Hello World admin!";
return "backupshell";
}
and logs snippet is as below:

The root resource directory src/main/resources/ isn't exposed publicly. As described in this post there are 4 directories which are automatically loaded by Spring Boot to serve static content:
/public/
/static/
/resources/
/META-INF/resources/
In your case you can put the HTML and the JS file inside ,e.g., the /public directory:
src/main/resources/public/backupshell.html
src/main/resources/public/myscripts.js
Then you can access the files with the address of your application, with default configuration it would be:
localhost:8080/backupshell.html
Note that 3rd option /resource/ doesn't mean that src/main/resources/ is exposed. It's the src/main/resources/resources/ directory, which can feel quite cumbersome.

Exclude resources in Spring Cloud Sleuth

I am investigating integrating Spring Cloud Sleuth into a new Spring Boot service we are building and want to exclude certain URL's from generating spans for example health check endpoints which are polled periodically.
Checking the code I can see that the TraceFilter created in the TraceWebAutoConfiguration.java has a DEFAULT_SKIP_PATTERN which can be overridden by setting spring.sleuth.instrument.web.skipPattern.
However even if I access a resource under the DEFAULT_SKIP_PATTERN I am still observing that a trace & span are being created i.e.
17:28:46.142 [XNIO-2 task-1] INFO o.s.c.sleuth.log.Slf4jSpanListener - Starting span: MilliSpan(begin=1454394526140, end=0, name=http/info, traceId=908b24a3-143f-4949-8f86-5df867e3985b, parents=[], spanId=908b24a3-143f-4949-8f86-5df867e3985b, remote=false, exportable=false, annotations={}, processId=null, timelineAnnotations=[])

Am I missing something? I am currently using 1.0.0.M4
A skipped resource does not stop a span from being created, it only stops the data from being collected and exported. So your logs look normal to me. In snapshots you would see the "exportable" flag set to false in skipped resources.
