# HAPI FHIR Server on Windows (PostgreSQL & Apache Tomcat)

以下針對在Windows環境下使用Tomcat架設HAPI FHIR Server的操作步驟做說明:

## 環境與系統說明

以下是介紹時使用之軟體與版本:

- Database: Postgresql 12.10
- Java Development Kit (JDK): 17.0.4.1
- Apache Tomcat: 9.0
- Docker: 24.0.6 (Maven install test時需要)
- IDE: Eclipse

## Getting Started

### Step1: Installation

- Postgresql: https://www.enterprisedb.com/downloads/postgres-postgresql-downloads
- hapi-fhir-jpaserver-starter: https://github.com/hapifhir/hapi-fhir-jpaserver-starter
- JDK: https://www.oracle.com/java/technologies/javase/jdk17-archive-downloads.html
- Tomcat: https://tomcat.apache.org/download-90.cgi
- Docker: https://docs.docker.com/desktop/install/windows-install/

### Step2: 設定Postgresql

開啟PgAdmin 4，設定User: [Login/Group Roles] > [Create] > [Login/Group Role]


設定User name和password
- user name: 位於General頁籤
- password: 位於Definition頁籤

於Privileges頁籤設定開啟 [Can Login?]

再來建立Database: [Databases] > [Create] > [Database]


設定Database Name，並選擇Owner為剛剛建立的User

### Step3: 建置

開啟Eclipse，建新專案

#### (1) 設定JDK
Window>Preference>Java>Install JREs
添入上面下載的JDK版本

#### (2)Import HAPI FHIR starter
將hapi-fhir-jpaserver-starter引入(Import時選擇Existing Maven Projects)

需要先執行Maven install: 右鍵>Run As>8.Maven Install (會花一段時間)，跑完如果是成功的會顯示BUILD SUCCESS


#### (3)設定application.yaml

設定檔: https://github.com/hapifhir/hapi-fhir-jpaserver-starter/blob/master/src/main/resources/application.yaml

設定使用Postgresql:

datasource:
    url: 'jdbc:postgresql://[localhost]:[port]/[table name]'
    username: [username]
    password: [password]
    driverClassName: org.postgresql.Driver
  jpa:
    properties:
      hibernate.dialect: ca.uhn.fhir.jpa.model.dialect.HapiFhirPostgres94Dialect
      hibernate.search.enabled: false

#### (5) 新增Server-Tomcat

新增Server>選擇Tomcat 9.0>Add the project



#### (6) Run the Server

把Server run起來:

成功🎺🎺:
