Issue description

custom filter is not applied. error.log is as below picture.

I am trying to deploy to vm using apisix-docker + apisix-java-plugin-runner. This was done with reference to the below.

1. https://apisix.apache.org/docs/apisix/2.15/getting-started/
2. https://github.com/apache/apisix-java-plugin-runner/blob/release/0.3.0/docs/zh/quick-start.md

-Detail step-

1. (ubuntu) git clone -b release/apisix-2.15.0 https://github.com/apache/apisix-docker.git

2. (local) git clone -b release/0.3.0 https://github.com/apache/apisix-java-plugin-runner.git

3. write custom plugins in local(macos)

4. (local) cd /apache/apisix-java-plugin-runner-release-0.3.0' and './mvnw package

5. (local) cd dist and Add Dockerfile

6. Transfer the dist folder(apache-apisix-java-plugin-runner-0.3.0-bin.tar.gz, Dockerfile) to ubuntu

7. (ubuntu) cd dist and docker build -t apache/apisix:2.15.0-alpine-with-java-plugin .

8. (ubuntu) Change the apisix image in docker-compose.yml

9. (ubuntu) add the configure in config.yaml file

10. (ubuntu) chmod 777 -R example

11. (ubuntu) cd example and docker-compose up -d

12. (ubuntu) create route and upstream curl "http://127.0.0.1:9080/apisix/admin/upstreams/99" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" -X PUT -d ' { "type": "roundrobin", "nodes": { "10.70.190.49:80": 1 } }' curl "http://127.0.0.1:9080/apisix/admin/routes/99" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" -X PUT -d ' { "methods": ["GET"], "uri": "/managesnsdata/*", "upstream_id": "99", "plugins": { "ext-plugin-pre-req": { "conf": [ { "name": "DemoFilter", "value":"{\"validate_header\":\"token\",\"rejected_code\":\"403\"}" } ] } } }'

13. and then curl is called(with/without header value), the custom filter(DemoFilter) is not applied and it responds normally.

How can i apply a filter? plz, review my step and solve this problem... Thank you in advance @tzssangglass

Environment

apisix-docker release/apisix-2.15.0 apisix-java-plugin-runner release/0.3.0 (local, ubuntu) JDK 11 local is macos Ubuntu 20.04.3 LTS

If you are starting the source code directly and putting filters in the runner-plugin, you need to change <artifactId>apisix-runner-plugin-sdk</artifactId> to <artifactId>apisix-runner-plugin</artifactId> in the pom.xml of the runner-core

[tzssangglass]

try with

sed -i 's/apisix-runner-plugin-sdk/apisix-runner-plugin/' runner-core/pom.xml

[Cheol-Soon-Choi]

try with

sed -i 's/apisix-runner-plugin-sdk/apisix-runner-plugin/' runner-core/pom.xml

@tzssangglass thanks for the answer, but i'm still a beginner. do you mean that change to sed -i 's/apisix-runner-plugin-sdk/apisix-runner-plugin/' instead of second line in dockerfile of step5?

or

RUN sed -i "s/dl-cdn.alpinelinux/org/mirrors.aliyun.com/g" /etc/apk/repositories && sed -i 's/apisix-runner-plugin-sdk/apisix-runner-plugin/' runner-core/pom.xml && apk add --no-cache openjdk11-jre

sorry, i can't understand...

[Cheol-Soon-Choi]

@tzssangglass And, is my step a general way to use apisix and java runner together? It cannot be clearly identified and understood with the current reference documentation...

[tzssangglass]

https://github.com/apache/apisix-java-plugin-runner/blob/d5421c292ef0d0ea93fb484afef668d7e2fc8767/runner-core/pom.xml#L38

I mean turn <artifactId>apisix-runner-plugin-sdk</artifactId> here into <artifactId>apisix-runner-plugin</artifactId>

why? Because you do:

• (local) git clone -b release/0.3.0 apache/apisix-java-plugin-runner.git

and you put your DemoFilter into runner-plugin.

After you have done with turned <artifactId>apisix-runner-plugin-sdk</artifactId> here into <artifactId>apisix-runner-plugin</artifactId>, the jar that generated by ./mvnw package would contain runner-plugin(include your DemoFilter).

And, is my step a general way to use apisix and java runner together? It cannot be clearly identified and understood with the current reference documentation...

There is some documentation(ref: https://github.com/apache/apisix-java-plugin-runner/blob/main/docs/en/latest/installation-guide.md), but it's not newbie friendly enough. I'm going to spend time refactoring the documentation.

@tzssangglass Thanks for your help. I will change dependency according to your advice.

And i've already read the installation reference. It was easy to follow(1. create spring boot ~ 6. implementing filter). But I didn't know what to do after that(my question is == how do i combine it with apisix? can i just run the boot image? etc...) That's why I asked if my step was the general way(apisix + java runner) because I couldn't solve the question for the above. I want to clearly understand and learn how to use apisix + java runner.
