QUESTION
spring-kafka creates a ValueSerializer instance in the AbstractConfig class using a no-args constructor.
I can see that JsonSerializer has an ObjectMapper constructor which I would like to use to inject a preconfigured ObjectMapper bean.
The default ObjectMapper includes null values in the response which I would like to remove. I added spring.jackson.default-property-inclusion: NON_EMPTY to my properties.yml but since Spring creates a default instance, this does not help me.
Could someone point me in the right direction?

QUESTION
This is now fixed with SpringBoot 2.5.1
Small question about a warning I am receiving please.
After the release of 2.5.0 of SpringBoot, I just did a version bump from 2.4.x to 2.5.0, without any code change.
Suddenly, on application start up, I am getting
kground-preinit] o.s.h.c.j.Jackson2ObjectMapperBuilder: For Jackson Kotlin classes support please add "com.fasterxml.jackson.module:jackson-module-kotlin" to the classpath
The thing is, my Springboot all is not a Kotlin app, it is a Java app.
It has nothing Kotlin.
Furthermore, I am not even doing any explicit JSON parsing.
May I ask how I can disable, resolve this warning please?
...ANSWER
Answered 2021-May-23 at 14:57There seems to be a solution here. The idea is to provide extra configuration for Jackson2ObjectMapperBuilderCustomizer. Sucks that a code change is required but there you have it.
QUESTION
I am trying to scrape the NBA player names and projected fantasy score (not single stat DFS) using selenium. I've gotten as far as using selenium to automate clicking NBA, and selecting the fantasy score tab.
From there, I see the players in a grid where I will like to scrape the points and names for each player. I have attempted to loop through the grid but I don't think I'm doing it right
Can someone please take a look at my code and point me in the right direction ?

QUESTION
I'm trying to scrape some data off ESPN and run some calculations off the scraped data. Ideally, I will like to iterate through a dataframe, grab the players name with Selenium, send the player's name into the search box and tell Selenium to click the player's name. I was able to do this successfully with one player. I'm not quite sure how to iterate through all the players in my data frame.
The second part of the code is where I'm struggling. For some reason I am not able to get the data. Selenium isn't able to find any of the elements. I don't think I'm doing it properly. If I am able to scrape the required data, I will like to plug them into a calculation and append the calculated projected points into my dataframe, dfNBA.
Can someone please help me with my code? and point me in the right direction. I'm trying to be more efficient writing python codes but right now I'm stuck
Thanks
...ANSWER
Answered 2021-Jun-13 at 15:52Here's some code to accomplish (I think) what you want. You need to wait for the table elements to appear, fix your xpath, and choose the right elements from the table array.

Answered 2021-Jun-13 at 15:15The log shows that the ResourcesPlugin is being found but its plug-in activator is getting a null pointer exception when it tries to get the IContentTypeManager.
The content type manager is provided using OSGi declarative services but you have not included org.apache.felix.scr which deals with this.
So at a minimum you need to include org.apache.felix.scr and start it in the section:
QUESTION
When a Kotlin class has a property that is one of the new @JvmInline value classes, Jackson converts it to JSON with a weird suffix on the field name.
e.g.
...ANSWER
Answered 2021-Jun-12 at 20:43Probably, upgrading jackson-module-kotlin will solve this problem.
https://github.com/FasterXML/jackson-module-kotlin/issues/356
If you can't upgrade, naming the getter as @get:JvmName("getModelName") should also solve the problem.
The reason for this problem is that the name of the method (getter) for the value class in Kotlin has a random suffix.
QUESTION
I'm getting this error because one of the fields in my domain class is a LocalDate. Stack trace below. Jackson is complaining about Java 8 date/time not being supported by default, but Spring Boot 2.5 comes with com.fasterxml.jackson.datatype:jackson-datatype-jsr310. How do I get Spring Batch to support my LocalDate field in my domain class?
If I change the field to be a java.util.Date it works perfectly.
Thanks!

Answered 2021-Jun-11 at 11:49The Go code you provided will not impact the way how the Time instance will be serialized as you are parsing it back into Time after serializing it to a string.
If you have control over how your date fields are serialized, you can apply the following format that should be aligned with what you provided to Jackson's ObjectMapper:

Install jackson
You can use jackson like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jackson component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
