keycloak18.0.0==本地源码启动

一个java开发2024-03-11 3:09

github下载源码，

版本18.0.0

java和maven的版本如下

复制代码

E:\keycloak-18.0.0>java -version
java version "21.0.1" 2023-10-17 LTS
Java(TM) SE Runtime Environment (build 21.0.1+12-LTS-29)
Java HotSpot(TM) 64-Bit Server VM (build 21.0.1+12-LTS-29, mixed mode, sharing)

E:\keycloak-18.0.0>mvn -version
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)

E:\keycloak-18.0.0>

修改maven的镜像仓库为官方指定的，否则会报错

复制代码

<mirrors>
  <mirror>
    <id>jboss-public-repository-group-https</id>
    <mirrorOf>jboss-public-repository-group</mirrorOf>
    <name>Jboss public https</name>
    <url>https://repository.jboss.org/nexus/content/groups/public/</url>
  </mirror>
</mirrors>

然后先install一遍下载各种依赖

mvn -Dmaven.test.skip clean install

可能会报错，没什么问题，只要能下载大部分的依赖就行

然后用IDEA打开源码

找到类

org.keycloak.testsuite.KeycloakServer

启动

可以发现默认使用了h2做了DB。

直接DEBUG启动，找到决定使用什么DB的地方

修改keycloak-server.json

复制代码

 "connectionsJpa": {
        "default": {
            "url": "${keycloak.connectionsJpa.url:jdbc:mysql://localhost:3306/keycloakTest?useSSL=false&serverTimezone=GMT%2B8&characterEncoding=UTF-8}",
            "driver": "${keycloak.connectionsJpa.driver:com.mysql.jdbc.Driver}",
            "driverDialect": "${keycloak.connectionsJpa.driverDialect:org.hibernate.dialect.MySQL5InnoDBDialect}",
            "user": "${keycloak.connectionsJpa.user:root}",
            "password": "${keycloak.connectionsJpa.password:123456}",
            "showSql": "${keycloak.connectionsJpa.showSql:}",
            "formatSql": "${keycloak.connectionsJpa.formatSql:}",
            "globalStatsInterval": "${keycloak.connectionsJpa.globalStatsInterval:}"
        }
    },

再次启动org.keycloak.testsuite.KeycloakServer

自动创建了一个超管账户admin admin

DB里自动初始化了几十个表
