QUESTION
I am getting a "Circular View Path Error" but I don't know why. If I am understanding it correctly this error occurs when you are stuck in a infinite loop. But I don't see an infinite Loop in my code. I googled the error, and tested every solution I found, but nothing worked.

...ANSWER
Answered 2022-Apr-17 at 01:52You get this error, because you did not fully configure Spring MVC, namely error handling part (and probably others).
Chain of events is as follows:
Call API and get 403 forbidden resource
2022-04-17 00:58:48.803 DEBUG 12924 --- [nio-8080-exec-6] o.s.s.w.a.i.FilterSecurityInterceptor : Failed to authorize filter invocation [GET /admin] with attributes [hasRole('ROLE_ADMIN')] 2022-04-17 00:58:48.803 DEBUG 12924 --- [nio-8080-exec-6] o.s.s.w.access.AccessDeniedHandlerImpl : Responding with 403 status code
Spring redirects to
/error
view:Request received for GET '/error': org.apache.catalina.core.ApplicationHttpRequest@1f38c9b6 servletPath:/error
Here something happens (it was not found, or something is missing), it leads to another error -> and here is when exception happens:
javax.servlet.ServletException: Circular view path [error]: would dispatch back to the current handler URL [/error] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
Solution:
- Try to search by "springboot mvc set up white lable error page".
- And also check why you get 403 status in the first place, as according to logs, you logged in as admin user. Please, read about spring security adding
ROLE_
prefix. Most probably, in the DB it has to beROLE_ADMIN
and in the codehasRole('ADMIN')
Hope, it helped
QUESTION
I have a data model called Project
which is lifecycled from an Angular app via Spring Data Rest. The Project
has Scene
s, Scenes have UpstreamKey
s held in a Map
and UpstreamKey
is an abstract class with two implementations ChromaKey
and LumaKey
. (see code below)
When I edit (PUT
) and existing Project
with a ChromaKey
in the map, and change that to a LumaKey
, I get an error message in the backend:
ANSWER
Answered 2022-Apr-05 at 02:03Though I can achieve the update in spring data mongodb, it's not possible in spring data rest now. In current spring data rest implementation, a PUT request try to merge the nested collection member by calling DomainObjectReader.mergeForPut(...)
which fails on type mismatch, rather than replace it. See this github issue and pull request.
So the workaround is implement a controller yourself.
Edit 2022-04-05Annotate UpstreamKey
with @Immutable
make spring data rest perform replacement rather than merge. This solution only works if the nested collection member is just value (no id, no audit data, no @JsonIgnore to hide server side data) instead of entity (with id).
Find the updated project and the diff
Below is result mongo data after the put opertaion.
QUESTION
I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.
In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux
dependencies.
I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.
I figured out that these lines in our build.gradle file are the origin of the problem.
...ANSWER
Answered 2022-Feb-08 at 12:36This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.
As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy
to ant-path-matcher
in your application.properties
file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy
. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

Here's advice
...ANSWER
Answered 2022-Mar-19 at 12:05Unable to match type List
because returning
clause also restricts matching to only those method executions that return a value of the specified type (Object
or it’s subtypes in this case, which will match any return value).
So, in your code, instead of:

Trying to add Springdoc to spring-boot-2.6.2 project. Application runs on embedded jetty server. Actuator runs ok with this below pom.xml setup.
When I try to run the application, below error occurs. Since I think this happens because of one of the dependencies, I tried to organize dependencies.

I have a file uploading api which was working perfectly fine under the spring boot
version 2.1.13
. After upgrading the version to 2.5.2
, it started to throw an exception. Looking at the changelogs, I couldn't see anything significant changes that's related to Multipart
processing. What could I be missing here? Below are the sample codes I have.

Answered 2021-Aug-17 at 17:03It turns out this issue was affected after the Spring Boot 2.2
. Since that version, the filter HttpHiddenMethodFilter
was disabled by default. The issue got fixed after enabling the filter in application.properties
