# Gradle start up script for POSIX generated by Gradle.
|
||||
#
|
||||
# Important for running:
|
||||
#
|
||||
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||
# noncompliant, but you have some other compliant shell such as ksh or
|
||||
# bash, then to run this script, type that shell name before the whole
|
||||
# command line, like:
|
||||
#
|
||||
# ksh Gradle
|
||||
#
|
||||
# Busybox and similar reduced shells will NOT work, because this script
|
||||
# requires all of these POSIX shell features:
|
||||
# * functions;
|
||||
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||
# * compound commands having a testable exit status, especially «case»;
|
||||
# * various built-in commands including «command», «set», and «ulimit».
|
||||
#
|
||||
# Important for patching:
|
||||
#
|
||||
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||
#
|
||||
# The "traditional" practice of packing multiple parameters into a
|
||||
# space-separated string is a well documented source of bugs and security
|
||||
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||
# options in "$@", and eventually passing that to Java.
|
||||
#
|
||||
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||
# see the in-line comments for details.
|
||||
#
|
||||
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||
# Darwin, MinGW, and NonStop.
|
||||
#
|
||||
# (3) This script is generated from the Groovy template
|
||||
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

### ✅ **Spring Boot에서 동적으로 N개의 데이터소스를 추가하고, 특정 이름에 따른 Connection Pool로 관리하기**
|
||||
> 🚀 **요구사항 업데이트:**
|
||||
> 1. **각 데이터소스는 특정한 이름(`dataSourceName`)으로 관리**.
|
||||
> 2. **각 데이터소스마다 개별적인 Connection Pool을 사용**.
|
||||
> 3. **동적으로 데이터소스를 추가할 수 있어야 함**.
|
||||
> 4. **각 데이터소스는 `TransactionManager`에 의해 관리됨**.
|
||||
> 5. **MyBatis와 연동**.
|
||||
|
||||
---
|
||||
|
||||
## **🔹 1. 데이터소스를 Connection Pool로 관리하는 `DynamicRoutingDataSource` 구현**
|
||||
각 데이터소스는 **Connection Pool(DBCP2)를 사용하여 동적으로 추가**하며,
|
||||
각 요청 시 **ThreadLocal을 이용하여 특정 데이터소스를 선택**할 수 있도록 `AbstractRoutingDataSource`를 활용합니다.
|
||||
|
||||
📄 **`DynamicRoutingDataSource.java`**
|
||||
```java
|
||||
import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;
|
||||
import javax.sql.DataSource;
|
||||
import java.util.Map;
|
||||
import java.util.concurrent.ConcurrentHashMap;
|
||||
|
||||
public class DynamicRoutingDataSource extends AbstractRoutingDataSource {
|
||||
|
||||
private static final ThreadLocal<String> contextHolder = new ThreadLocal<>();
|
||||
private final Map<Object, Object> dataSourceMap = new ConcurrentHashMap<>();
|
||||
|
||||
@Override
|
||||
protected Object determineCurrentLookupKey() {
|
||||
return contextHolder.get();
|
||||
}
|
||||
|
||||
public void setDataSource(String dataSourceName) {
|
||||
contextHolder.set(dataSourceName);
|
||||
}
|
||||
|
||||
public void clearDataSource() {
|
||||
contextHolder.remove();
|
||||
}
|
||||
|
||||
public void addDataSource(String name, DataSource dataSource) {
|
||||
dataSourceMap.put(name, dataSource);
|
||||
super.setTargetDataSources(dataSourceMap);
|
||||
super.afterPropertiesSet();
|
||||
}
|
||||
|
||||
public Map<Object, Object> getDataSourceMap() {
|
||||
return dataSourceMap;
|
||||
}
|
||||
}
|
||||
```
|
||||
✅ **기능:**
|
||||
- `setDataSource("dataSourceName")`을 호출하면 **해당 데이터소스를 선택**하여 사용.
|
||||
- `addDataSource("dataSourceName", DataSource)`을 통해 **새로운 데이터소스를 동적으로 추가 가능**.
|
||||
- `ConcurrentHashMap`을 사용하여 **Connection Pool을 효율적으로 관리**.
|
||||
|
||||
---
|
||||
|
||||
## **🔹 2. 데이터소스 설정 및 Connection Pool 관리**
|
||||
각 데이터소스는 **DBCP2 커넥션 풀**을 사용하여 생성됩니다.

||||

||||

|
||||
✅ **기능:**
|
||||
- `createDataSource()`를 사용하여 **각각의 데이터소스를 DBCP2 기반 Connection Pool로 생성**.
|
||||
- `dynamicRoutingDataSource.addDataSource("default", defaultDataSource);`를 호출하여 기본 데이터소스를 등록.
|
||||
|
||||

|
||||
|
||||
## **🔹 3. 새로운 데이터소스를 동적으로 추가하는 서비스**
|
||||
📄 **`DynamicDataSourceService.java`**
|
||||
```java
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.stereotype.Service;
|
||||
import javax.sql.DataSource;
|
||||
|
||||
@Service
|
||||
public class DynamicDataSourceService {
|
||||
|
||||
@Autowired
|
||||
private DynamicRoutingDataSource dynamicRoutingDataSource;
|
||||
|
||||
public void addNewDataSource(String dataSourceName, String url, String username, String password) {
|
||||
DataSource newDataSource = createDataSource(url, username, password);
|
||||
dynamicRoutingDataSource.addDataSource(dataSourceName, newDataSource);
|
||||
System.out.println("✅ 새로운 데이터소스 추가됨: " + dataSourceName);
|
||||
}
|
||||
|
||||
private DataSource createDataSource(String url, String username, String password) {
|
||||
PooledDataSource dataSource = new PooledDataSource();
|
||||
dataSource.setDriver("com.mysql.cj.jdbc.Driver");
|
||||
dataSource.setUrl(url);
|
||||
dataSource.setUsername(username);
|
||||
dataSource.setPassword(password);
|
||||
return dataSource;
|
||||
}
|
||||
}
|
||||
```
|
||||
✅ **기능:**
|
||||
- `addNewDataSource("newDB", "jdbc:mysql://localhost:3306/new_db", "user", "pass")`을 호출하면 **새로운 데이터소스를 동적으로 추가**.
|
||||
- `dynamicRoutingDataSource.addDataSource(dataSourceName, newDataSource)`을 사용하여 **데이터소스를 관리하는 Connection Pool에 추가**.
|
||||
|
||||
---
|
||||
|
||||
## **🔹 4. 특정 데이터소스를 선택하여 트랜잭션 처리**
|
||||
📄 **`UserService.java`**
|
||||
```java
|
||||
import org.springframework.beans.factory.annotation.Autowired;
|
||||
import org.springframework.stereotype.Service;
|
||||
import org.springframework.transaction.annotation.Transactional;
|
||||
|
||||
@Service
|
||||
public class UserService {
|
||||
|
||||
@Autowired
|
||||
private UserMapper userMapper;
|
||||
|
||||
public void fetchUsersFromDefault() {
|
||||
DynamicRoutingDataSource.setDataSource("default");
|
||||
System.out.println("🔹 Default DB에서 데이터 조회");
|
||||
System.out.println(userMapper.findAll());
|
||||
}
|
||||
|
||||
@Transactional
|
||||
public void fetchUsersFromNewDB() {
|
||||
DynamicRoutingDataSource.setDataSource("newDB");
|
||||
System.out.println("🔹 New DB에서 데이터 조회");
|
||||
System.out.println(userMapper.findAll());
|
||||
}
|
||||
}
|
||||
```
|
||||
📄 **`UserMapper.java`**
|
||||
```java
|
||||
import org.apache.ibatis.annotations.Mapper;
|
||||
import org.apache.ibatis.annotations.Select;
|
||||
import java.util.List;
|
||||
import java.util.Map;
|
||||
|
||||
@Mapper
|
||||
public interface UserMapper {
|
||||
@Select("SELECT * FROM users")
|
||||
List<Map<String, Object>> findAll();
|
||||
}
|
||||
```
|
||||
✅ **기능:**
|
||||
- `DynamicRoutingDataSource.setDataSource("newDB")`를 호출하면 **특정 데이터소스를 선택**.
|
||||
- MyBatis에서 **선택된 데이터소스를 기반으로 SQL 실행**.
|
||||
- `@Transactional`을 사용하여 **선택된 데이터소스에서 트랜잭션 처리** 가능.
|
||||
|
||||
---
|
||||
|
||||
## ✅ **최종 정리**
|
||||
| 기능 | 코드 |
|
||||
|------|------|
|
||||
| **동적으로 데이터소스 변경** | `DynamicRoutingDataSource.setDataSource("dataSourceName")` |
|
||||
| **새로운 데이터소스 추가** | `dynamicDataSourceService.addNewDataSource("newDB", "url", "user", "pass")` |
|
||||
| **Connection Pool 관리** | `PooledDataSource` (MyBatis DBCP2 사용) |
|
||||
| **트랜잭션 관리** | `@Transactional` 사용 |
|
||||
| **MyBatis 연동** | `SqlSessionFactory` + `SqlSessionTemplate` 사용 |
|
||||
|
||||
✅ **이제 애플리케이션 실행 중에도 N개의 데이터소스를 추가하고, Connection Pool로 관리하며, MyBatis와 연동하여 사용할 수 있습니다!** 🚀
