Event Store Service

event-store-service is for data consistency support. It is necessary to cooperate with choerodon-starter-event-producer and choerodon-starter-event-consumer to implement data consistency. Currently, the message queue kafka is supported.

Feature

• Complete the front page. After the failed message is sent back to event-store-service, manually click on Retry on the page to resend the message.
• rabbitmq, redis, and rocketmq may also be supported.

Requirements

• This service is an eureka client service. The local operation needs to cooperate with eureka-server, and the online operation needs to cooperate with go-register-server.
• It must be used with choerodon-starter-event-producer and choerodon-starter-event-consumer to achieve data consistency.

Installation and Getting Started

1. Start up eureka-server

2. Start up kafka

3. Create a event_store_service database in mysql：

   CREATE USER 'choerodon'@'%' IDENTIFIED BY "123456";
   CREATE DATABASE event_store_service DEFAULT CHARACTER SET utf8;
   GRANT ALL PRIVILEGES ON event_store_service.* TO choerodon@'%';
   FLUSH PRIVILEGES;

   New file of "init-local-database.sh" in the root directory of the event-store-service project：

   mkdir -p target
   if [ ! -f target/choerodon-tool-liquibase.jar ]
   then
       curl http://nexus.choerodon.com.cn/repository/choerodon-release/io/choerodon/choerodon-tool-liquibase/0.5.2.RELEASE/choerodon-tool-liquibase-0.5.2.RELEASE.jar -o target/choerodon-tool-liquibase.jar
   fi
   java -Dspring.datasource.url="jdbc:mysql://localhost/event_store_service?useUnicode=true&characterEncoding=utf-8&useSSL=false" \
    -Dspring.datasource.username=choerodon \
    -Dspring.datasource.password=123456 \
    -Ddata.drop=false -Ddata.init=true \
    -Ddata.dir=src/main/resources \
    -jar target/choerodon-tool-liquibase.jar

   And executed in the root directory of the event-store-service project：

   sh init-local-database.sh

4. Then run the project in the root directory of the project：

   mvn spring-boot:run

Usage

• configuration

  choerodon:
      event:
        store:
