spring boot多数据源配置

1.application.properties

spring.datasource.url = jdbc\:oracle\:thin\:@192.168.3.888\:1521\:orcl
spring.datasource.username =
spring.datasource.password =
spring.datasource.driverClassName = oracle.jdbc.driver.OracleDriverspring.datasource.enp.url = jdbc\:oracle\:thin\:@192.168.3.888\:1521\:orcl
spring.datasource.enp.username = 8888
spring.datasource.enp.password = 8888
spring.datasource.enp.driverClassName = oracle.jdbc.driver.OracleDriverspring.datasource.initialSize = 100
spring.datasource.maxActive = 130
spring.datasource.minIdle = 10
spring.datasource.maxIdle = 30
spring.datasource.maxWait = 5000
spring.datasource.testOnBorrow = true
spring.datasource.validationQuery = SELECT 1 FROM DUAL
spring.datasource.validationInterval = 10000
spring.datasource.timeBetweenEvictionRunsMillis = 5000
spring.datasource.minEvictableIdleTimeMillis = 5000
spring.datasource.removeAbandoned = true
spring.datasource.removeAbandonedTimeout = 60
spring.jpa.database = ORACLE
spring.jpa.show-sql = false
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.OracleDialect

2.DataSourceConfig.java—配置数据源

import java.sql.SQLException;import javax.sql.DataSource;import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;import com.alibaba.druid.pool.DruidDataSource;@Configuration
public class DataSourceConfig {@Value("${spring.datasource.url}")public String dbUrl;@Value("${spring.datasource.username}")public String dbUserName;@Value("${spring.datasource.password}")public String dbPassword;@Value("${spring.datasource.driverClassName}")public String driverClassName;@Bean(name = "enpDataSource")@Qualifier("enpDataSource")@ConfigurationProperties(prefix="spring.datasource.enp")public DataSource enpDataSource(){return DataSourceBuilder.create().build();}@Primary@Bean(name = "primaryDataSource")@Qualifier("primaryDataSource")
//  @ConfigurationProperties(prefix="spring.datasource")public DataSource primaryDataSource(){return createDataSource(driverClassName,dbUrl,dbUserName,dbPassword);}private DataSource createDataSource(String driverClassName, String url,String username, String password) {DruidDataSource dataSource = new DruidDataSource();dataSource.setDriverClassName(driverClassName);dataSource.setUrl(url);dataSource.setUsername(username);dataSource.setPassword(password);// 初始化大小，最小，最大dataSource.setInitialSize(5);dataSource.setMinIdle(5);dataSource.setMaxActive(10);// 配置获取连接等待超时的时间dataSource.setMaxWait(60000);// 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒dataSource.setTimeBetweenEvictionRunsMillis(60000);//配置一个连接在池中最小生存的时间，单位是毫秒dataSource.setMinEvictableIdleTimeMillis(300000);dataSource.setValidationQuery("select 1 from dual");dataSource.setTestWhileIdle(true);dataSource.setTestOnBorrow(false);dataSource.setTestOnReturn(false);// 打开PSCache，并且指定每个连接上PSCache的大小dataSource.setPoolPreparedStatements(true);dataSource.setMaxPoolPreparedStatementPerConnectionSize(10);//配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙try {dataSource.setFilters("stat,wall,log4j");} catch (SQLException e) {}//通过connectProperties属性来打开mergeSql功能；慢SQL记录dataSource.setConnectionProperties("=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000");System.out.println(dataSource);return dataSource;}}

3.PrimaryDbConfig.java—主数据源

import java.util.Map;import javax.persistence.EntityManager;
import javax.sql.DataSource;import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.orm.jpa.JpaProperties;
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.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef="entityManagerFactoryPrimary",transactionManagerRef="transactionManagerPrimary",basePackages= { "com.boor" }) //设置Repository所在位置public class PrimaryDbConfig {@Autowired @Qualifier("primaryDataSource")private DataSource primaryDataSource;@Primary@Bean(name = "entityManagerPrimary")public EntityManager entityManager(EntityManagerFactoryBuilder builder) {return entityManagerFactoryPrimary(builder).getObject().createEntityManager();}@Primary@Bean(name = "entityManagerFactoryPrimary")public LocalContainerEntityManagerFactoryBean entityManagerFactoryPrimary (EntityManagerFactoryBuilder builder) {return builder.dataSource(primaryDataSource).properties(getVendorProperties(primaryDataSource)).packages("com.boor.fdlss") //设置实体类所在位置.persistenceUnit("primaryPersistenceUnit").build();}@Autowiredprivate JpaProperties jpaProperties;private Map<String, String> getVendorProperties(DataSource dataSource) {return jpaProperties.getHibernateProperties(dataSource);}@Primary@Bean(name = "transactionManagerPrimary")public PlatformTransactionManager transactionManagerPrimary(EntityManagerFactoryBuilder builder) {return new JpaTransactionManager(entityManagerFactoryPrimary(builder).getObject());}}

3.EnpDbConfig.java—次数据源配置

package com.boor.config;import java.util.Map;import javax.persistence.EntityManager;
import javax.sql.DataSource;import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.orm.jpa.JpaProperties;
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.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef="entityManagerFactoryEnp",transactionManagerRef="transactionManagerEnp",basePackages= { "com.boor.enp" }) //设置Repository所在位置public class EnpDbConfig {@Autowired @Qualifier("enpDataSource")private DataSource enpDataSource;@Bean(name = "entityManagerEnp")public EntityManager entityManager(EntityManagerFactoryBuilder builder) {return entityManagerFactoryEnp(builder).getObject().createEntityManager();}@Bean(name = "entityManagerFactoryEnp")public LocalContainerEntityManagerFactoryBean entityManagerFactoryEnp (EntityManagerFactoryBuilder builder) {return builder.dataSource(enpDataSource).properties(getVendorProperties(enpDataSource)).packages("com.boor.enp") //设置实体类所在位置.persistenceUnit("enpPersistenceUnit").build();}@Autowiredprivate JpaProperties jpaProperties;private Map<String, String> getVendorProperties(DataSource dataSource) {return jpaProperties.getHibernateProperties(dataSource);}@Bean(name = "transactionManagerEnp")public PlatformTransactionManager transactionManagerEnp(EntityManagerFactoryBuilder builder) {return new JpaTransactionManager(entityManagerFactoryEnp(builder).getObject());}}
