            SpringBoot: Validation without @Valid annotation
            Asked 2021-Nov-23 at 04:53

            I have a web socket handler inherited from AbstractWebSocketHandler that handles text messages. My DTOs use javax.validation.constraints for validation. So, in my REST endpoints, I simply can use the @Valid annotation to invoke the validator. However, as far as I know, this annotation is not usable in my web socket handler. How can I invoke the SpringBoot validator programmatically without this annotation?

            Besides, is it possible to use the SpringBoot de-serializer for messages instead of JSON.parseObject?

            You will use a Validator to fill a list of ConstraintViolation. An example could looks like this :

            how to generate signed apk in android studio
            Asked 2021-Oct-28 at 02:25

            In my case, I have my signature key and I have generated the apk with function menubuild--->generate signed Bundle/Apk

            Here are the steps how I generate this apk:

            step 1:

            step 2:


            When I put this generated release apk into my real device, it will work well.

            But when I tried to send this apk to my application center, it said that I don't have any signature file in this apk.

            According to many issues found on google, I have noticed that there was actually no signature file in my apk at all. It seems that Android studio's build--->generate signed Bundle/Apk didn't work at all, there was only a release with no signature that generated.

            I'm quite new in android developing. I wonder if there are some mistakes in my gradle settings.

            My application has 2 file like this picture:

            Can't understand/find error in JSON config file referenced by Unity logs
            Asked 2021-Apr-05 at 14:19

            I have customized this JSON config file for a mod from the game Valheim. The mods make use of a Unity program in order to load the mods up and it shows a console log so you can find errors while loading the game with said mods. I am getting this constant error in the Unity console regarding the file, but cannot understand the error or find any errors in the files JSON formatting.

            The error is as follows



            Answered 2021-Apr-05 at 14:19

            What the error message is saying is that 14451th character is wrong (from the json parser's point of view).

            This character index is not very helpful to me. So, to explore this further, I've removed the comments with a regex (in the regex101 link, click on "substitution" on the left panel to see the version without comments). [*]

            Then I pasted the comment-less version in an online JSON parser.

            The output is a bit more precise:

            java.lang.StackOverflowError happens when connect to Neo4j, in Springboot Mybatis
            Asked 2020-Dec-31 at 15:28

            As the title suggests, I met the StackOverFlow problem when I connect to Neo4j in Springboot with Mybatis. The CQL runs well in Neo4j desktop, but the api returns a 500 result with the same CQL in mapper.

            The error message goes like:



            Answered 2020-Dec-31 at 15:28

            As far as I know, there is no MyBatis integration in:

            • neither Spring Data Neo4j 5 (added via spring-boot-starter-data-neo4j in your POM, included up until Spring Boot 2.3)
            • nor Neo4j OGM (which is the library Spring Data Neo4j 5 is built upon).

            If you want to get started, you should probably get started with Spring Data Neo4j 6 (aka SDN 6), i.e. the latest version of Spring Data Neo4j at the time of writing. If you upgrade Spring Boot to the latest version (2.4 at the time of writing), you will automatically get it.

            You should probably start with the reference documentation of SDN 6. You also can find an example here.

            As you will learn, you can get rid of MyBatis, SDN 6 (and 5 via Neo4j OGM) takes care of the mapping already.



            Error creating bean with name 'projectController': Unsatisfied dependency expressed through field 'service';
            Asked 2020-Nov-20 at 07:59

            I use the following configuration and code to create a spring boot application.




            Answered 2020-Nov-18 at 06:08

            Spring's complaint is that you haven't defined a Bean of type ProjectMapper, which it is saying that it needs to satisfy an Autowire request. Looking at your code, I don't see a definition for such a Bean in what you've shown us here.

            The exact point of the problem is hidden, I'm guessing, because you aren't showing us the definition of the ServiceImpl class. My guess is that that's where the actual reference is that Spring is trying to wire up. Apparently, the field name is baseMapper.
