Spring Boot Oracle SqlServer 多数据源连接配置
- 1、pom.xml配置文件，添加依赖
- 2、properties配置文件，添加多数据源配置
- 3、新建datasource配置类
- 4、新建各数据源配置类
1、pom.xml配置文件添加依赖
org.springframework.boot
spring-boot-starter-parent
2.0.3.RELEASE
com.oracle
ojdbc6
11.2.0.4
com.microsoft.sqlserver
mssql-jdbc
7.2.2.jre8
com.zaxxer
HikariCP
3.3.1
2、properties配置文件，添加多数据源配置
# Oracle数据源1
spring.datasource.primary.jdbc-url=jdbc:oracle:thin:@127.0.0.1:1521/dbName1
spring.datasource.primary.username=username
spring.datasource.primary.password=password
spring.datasource.primary.driver-class-name=oracle.jdbc.OracleDriver
# Oracle数据源2
spring.datasource.second.jdbc-url=jdbc:oracle:thin:@127.0.0.1:1521/dbName2
spring.datasource.second.username=username
spring.datasource.second.password=password
spring.datasource.second.driver-class-name=oracle.jdbc.OracleDriver
# SqlServer数据源3
spring.datasource.third.jdbc-url=jdbc:sqlserver://127.0.0.1:1433;DatabaseName=dbName3
spring.datasource.third.username=username
spring.datasource.third.password=password
spring.datasource.third.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
#各数据源 配置
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.properties.hibernate.max_fetch_depth=1
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
spring.jpa.open-in-view=false
## Hikari 连接池配置
## 连接池名称
spring.datasource.primary.pool-name=HikariPool-1
## 最小空闲连接数量，默认是10
spring.datasource.primary.minimum-idle=5
## 连接池最大连接数，默认是10
spring.datasource.primary.maximum-pool-size=10
## 空闲连接存活最大时间，默认600000（10分钟）
spring.datasource.primary.idle-timeout=600000
## 此属性控制池中连接的最长生命周期，值0表示无限生命周期，默认1800000即30分钟
spring.datasource.primary.max-lifetime=1800000
## 数据库连接超时时间,默认30秒，即30000
spring.datasource.primary.connection-timeout=30000
spring.datasource.second.pool-name=HikariPool-2
spring.datasource.second.minimum-idle=5
spring.datasource.second.maximum-pool-size=10
spring.datasource.second.idle-timeout=600000
spring.datasource.second.max-lifetime=1800000
spring.datasource.second.connection-timeout=30000
spring.datasource.third.pool-name=HikariPool-3
spring.datasource.third.minimum-idle=5
spring.datasource.third.maximum-pool-size=10
spring.datasource.third.idle-timeout=600000
spring.datasource.third.max-lifetime=1800000
spring.datasource.third.connection-timeout=30000
## 日志级别
logging.level.web=DEBUG
logging.level.root=DEBUG
3、新建datasource配置类
数据源配置.png
如图所示，在config包下，新建datasource包，再在其下新建DataSourceConfig管理类，最后再添加各个数据源单独配置类
DataSourceConfig.java
import com.zaxxer.hikari.HikariDataSource;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import javax.sql.DataSource;
@Slf4j
@Configuration
public class DataSourceConfig {
/**
* 数据源1
*
* @return DataSource
*/
@Primary
@Bean(name = "primaryDataSource")
@ConfigurationProperties(prefix = "spring.datasource.primary")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
/**
* 数据源2
*
* @return DataSource
*/
@Bean(name = "secondDataSource")
@ConfigurationProperties(prefix = "spring.datasource.second")
public DataSource secondDataSource() {
return DataSourceBuilder.create().build();
}
/**
* 数据源3
*
* @return DataSource
*/
@Bean(name = "thirdDataSource")
@ConfigurationProperties(prefix = "spring.datasource.third")
public DataSource thirdDataSource() {
return DataSourceBuilder.create().build();
}
/**
* 显示数据库连接池信息
*
* @param dataSource 连接池信息
*/
static void logDS(DataSource dataSource) {
HikariDataSource hds = (HikariDataSource) dataSource;
String info = "\n\n\tHikariCP连接池配置\n\t连接池名称：" +
hds.getPoolName() +
"\n\t最小空闲连接数：" +
hds.getMinimumIdle() +
"\n\t最大连接数：" +
hds.getMaximumPoolSize() +
"\n\t连接超时时间：" +
hds.getConnectionTimeout() +
"ms\n\t空闲连接超时时间：" +
hds.getIdleTimeout() +
"ms\n\t连接最长生命周期：" +
hds.getMaxLifetime() +
"ms\n";
log.info(info);
}
}
4、新建各数据源配置类
PrimaryDataSourceConfig.java
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateSettings;
import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.boot.autoconfigure.orm.jpa.JpaProperties;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.persistence.EntityManager;
import javax.sql.DataSource;
import java.util.Map;
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactoryPrimary",
transactionManagerRef = "transactionManagerPrimary",
basePackages = {"*************.repository.primary"}) // repository层位置
public class PrimaryDataSourceConfig {
@Autowired
@Qualifier("primaryDataSource")
private DataSource primaryDataSource;
@Autowired
private JpaProperties jpaProperties;
@Primary
@Bean(name = "entityManagerPrimary")
public EntityManager entityManager(EntityManagerFactoryBuilder builder) {
return entityManagerFactoryPrimary(builder).getObject().createEntityManager();
}
@Primary
@Bean(name = "entityManagerFactoryPrimary")
public LocalContainerEntityManagerFactoryBean entityManagerFactoryPrimary(EntityManagerFactoryBuilder builder) {
DataSourceConfig.logDS(primaryDataSource);
return builder
.dataSource(primaryDataSource)
.properties(getVendorProperties())
.packages("*************.entity.primary") // 设置实体类所在位置
.persistenceUnit("primaryPersistenceUnit")
.build();
}
/**
* hibernate配置
*
* @return
*/
private Map getVendorProperties() {
Map ret = jpaProperties.getHibernateProperties(new HibernateSettings());
ret.put("hibernate.dialect", "org.hibernate.dialect.OracleDialect");
return ret;
}
@Primary
@Bean(name = "transactionManagerPrimary")
public PlatformTransactionManager transactionManagerPrimary(EntityManagerFactoryBuilder builder) {
return new JpaTransactionManager(entityManagerFactoryPrimary(builder).getObject());
}
}
注意，以下信息按照项目填写
- repository层位置
- 实体类所在位置
- hibernate配置，数据源SQL方言
