低代码知识图谱软件项目

面向低代码开发的知识图谱构建及检索服务

环境配置

JDK 17
Spring Boot 3.3.4
Maven 3.9.9

Neo4j 配置

使用 docker 配置，neo4j 版本为 5.24

请提前准备一个文件夹 {your_path}，用来挂载容器内的目录

docker pull neo4j:5.24

docker run -d -p 7474:7474 -p 7687:7687 --name neo4j-5.24 -e "NEO4J_AUTH=neo4j/neo4j123456" -v {your_path}/data:/data -v {your_path}/logs:/logs -v {your_path}/conf:/var/lib/neo4j/conf -v {your_path}/import:/var/lib/neo4j/import neo4j:5.24

ES 配置

使用 docker 配置 elasticsearch 的版本为8.15.0

docker pull docker.elastic.co/elasticsearch/elasticsearch:8.15.0

docker run -d --name elasticsearch \
  -e ELASTIC_USERNAME=elastic \
  -e ELASTIC_PASSWORD=changeme \
  -e discovery.type=single-node \
  -p 9200:9200 \
  -p 9300:9300 \
  docker.elastic.co/elasticsearch/elasticsearch:8.15.0

需要对于 elasticsearch 容器的 Files/usr/share/elasticsearch/config/elasticsearch.yml 作如下配置

cluster.name: "docker-cluster"
network.host: 0.0.0.0

运行

• 编译打包：mvn package -Dmaven.test.skip=true（跳过测试，可选）
• 执行插件：java -jar target/LowCodeKG-0.0.1-SNAPSHOT.jar -gen {yml_config_path}
• 启动服务：java -jar target/LowCodeKG-0.0.1-SNAPSHOT.jar -exec
