spring boot配置多数据源

1、pom.xml文件

<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<!-- 测试 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.1.1</version>
</dependency>
<!-- mysql 依赖 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!-- springboot-web组件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

2、application.properties

###datasource1
spring.datasource.test1.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.test1.jdbc-url = jdbc:mysql://localhost:3306/xiangwen?useUnicode=true&characterEncoding=utf-8
spring.datasource.test1.username = root
spring.datasource.test1.password = 12345678
###datasource2
spring.datasource.test2.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.test2.jdbc-url = jdbc:mysql://localhost:3306/xiangwu?useUnicode=true&characterEncoding=utf-8
spring.datasource.test2.username = root
spring.datasource.test2.password = 12345678

3、DataSource1Config.java

package com.xiangwen.datasource;

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;

import org.springframework.jdbc.datasource.DataSourceTransactionManager;

@Bean(name = "test1SqlSessionFactory")
public SqlSessionFactory testSqlSessionFactory(@Qualifier("test1DataSource") DataSource dataSource)
throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
// bean.setMapperLocations(

return bean.getObject();
}

@Bean(name = "test1TransactionManager")
public DataSourceTransactionManager testTransactionManager(@Qualifier("test1DataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}

@Bean(name = "test1SqlSessionTemplate")
public SqlSessionTemplate testSqlSessionTemplate(
@Qualifier("test1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}

}

4、UserDaoTest1.java

package com.xiangwen.respostory1;

import lombok.extern.slf4j.Slf4j;

@Mapper
public interface UserDaoTest1 {
    public int adduser(String name, int age) ;
}

5、UserServices1.java

package com.xiangwen.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.xiangwen.dao1.UserDaoTest1;

import lombok.extern.slf4j.Slf4j;

@Service
@Slf4j
public class UserServicer1 {
@Autowired
private UserDaoTest1 userDaoTest1;

@Transactional(transactionManager = "test1TransactionManager")
public int adduser(String name, int age) {
int res = userDaoTest1.inserUser(name, age);
log.info("============进来了UserServer1");
int a = 1 / age;
return res;
}
}
