springboot配置多数据源（二）

spring+mybatis配置多数据源

背景：在springboot配置多数据源（一）的基础上进行

一、配置固定数据源

1. application.yml文件增加数据源

spring:  
  second-datasource:
    username: root
    password: 1234
    jdbc-url: jdbc:mysql://127.0.0.1:3306/test2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      maximum-pool-size: 20
      max-lifetime: 1800000
      idle-timeout: 30000
      data-source-properties:
        prepStmtCacheSize: 250
        prepStmtCacheSqlLimit: 2048
        cachePrepStmts: true
        useServerPrepStmts: true
  third-datasource:
    username: root
    password: 1234
    jdbc-url: jdbc:mysql://127.0.0.1:3306/test3?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      maximum-pool-size: 20
      max-lifetime: 1800000
      idle-timeout: 30000
      data-source-properties:
        prepStmtCacheSize: 250
        prepStmtCacheSqlLimit: 2048
        cachePrepStmts: true
        useServerPrepStmts: true
  fourth-datasource:
    username: root
    password: 1234
    jdbc-url: jdbc:mysql://127.0.0.1:3306/test4?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.zaxxer.hikari.HikariDataSource
    hikari:
      maximum-pool-size: 20
      max-lifetime: 1800000
      idle-timeout: 30000
      data-source-properties:
        prepStmtCacheSize: 250
        prepStmtCacheSqlLimit: 2048
        cachePrepStmts: true
        useServerPrepStmts: true

2. 添加数据库配置(DataBaseConfig.java)

@Bean(name = "secondDataSource")
    @ConfigurationProperties(prefix = "spring.second-datasource")
    public DataSource secondDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "thirdDataSource")
    @ConfigurationProperties(prefix = "spring.third-datasource")
    public DataSource thirdDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "fourthDataSource")
    @ConfigurationProperties(prefix = "spring.fourth-datasource")
    public DataSource fourthDataSource() {
        return DataSourceBuilder.create().build();
    }

3. 分别进行各数据源配置

package com.zsx.config;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = {"com.zsx.mapper.primary"}, sqlSessionFactoryRef = "primarySqlSessionFactory")
public class MybatisDBPrimaryConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(MybatisDBPrimaryConfig.class);

    @Bean(name = "primarySqlSessionFactory")
    public SqlSessionFactory primarySqlSessionFactory(@Qualifier("primaryDataSource") DataSource primaryDataSource) throws Exception {
        LOGGER.info("====================");
        LOGGER.info("primaryDataSource=========" + primaryDataSource);
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(primaryDataSource);
        factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/primary/*.xml"));
        return factoryBean.getObject();

    }

    @Bean(name = "primarySqlSessionTemplate")
    public SqlSessionTemplate primarySqlSessionTemplate(@Qualifier("primarySqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean(name = "primaryTransactionManager")
    public DataSourceTransactionManager primaryTransactionManager(@Qualifier("primaryDataSource") DataSource primaryDataSource) {
        return new DataSourceTransactionManager(primaryDataSource);
    }
}

package com.zsx.config;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = {"com.zsx.mapper.second"}, sqlSessionFactoryRef = "secondSqlSessionFactory")
public class MybatisDBSecondConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(MybatisDBSecondConfig.class);

    @Bean(name = "secondSqlSessionFactory")
    public SqlSessionFactory secondSqlSessionFactory(@Qualifier("secondDataSource") DataSource secondDataSource) throws Exception {
        LOGGER.info("====================");
        LOGGER.info("secondDataSource=========" + secondDataSource);
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(secondDataSource);
        factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/second/*.xml"));
        return factoryBean.getObject();

    }

    @Bean(name = "secondSqlSessionTemplate")
    public SqlSessionTemplate secondSqlSessionTemplate(@Qualifier("secondSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean(name = "secondTransactionManager")
    public DataSourceTransactionManager secondTransactionManager(@Qualifier("secondDataSource") DataSource secondDataSource) {
        return new DataSourceTransactionManager(secondDataSource);
    }
}

package com.zsx.config;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = {"com.zsx.mapper.third"}, sqlSessionFactoryRef = "thirdSqlSessionFactory")
public class MybatisDBThirdConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(MybatisDBThirdConfig.class);

    @Bean(name = "thirdSqlSessionFactory")
    public SqlSessionFactory sqlSessionFactory(@Qualifier("thirdDataSource") DataSource thirdDataSource) throws Exception {
        LOGGER.info("====================");
        LOGGER.info("thirdDataSource=========" + thirdDataSource);
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(thirdDataSource);
        factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/third/*.xml"));
        return factoryBean.getObject();

    }

    @Bean(name = "thirdSqlSessionTemplate")
    public SqlSessionTemplate thirdSqlSessionTemplate(@Qualifier("thirdSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean(name = "thirdTransactionManager")
    public DataSourceTransactionManager thirdTransactionManager(@Qualifier("thirdDataSource") DataSource thirdDataSource) {
        return new DataSourceTransactionManager(thirdDataSource);
    }

}

4. 分别编写对应的数据接口

package com.zsx.mapper.primary;

import com.zsx.entity.User;
import org.springframework.stereotype.Repository;

@Repository("userMapper0")
public interface UserMapper {

    User findById(Integer id);

    User findById1(Integer id);
}

package com.zsx.mapper.second;

import com.zsx.entity.User;
import org.springframework.stereotype.Repository;

@Repository("userMapper2")
public interface UserMapper {

    User findById(Integer id);
}

package com.zsx.mapper.third;

import com.zsx.entity.User;
import org.springframework.stereotype.Repository;

@Repository("userMapper3")
public interface UserMapper {

    User findById(Integer id);
}

5. 分别在资源目录下创建键对应的mapper映射文件(resources\mybatis\mapper\primary\primary-user-mapper.xml、resources\mybatis\mapper\second\second-user-mapper.xml、resources\mybatis\mapper\third\third-user-mapper.xml)

5.1 primary-user-mapper.xml

    
        
        
        
        
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

    
        SELECT id, name FROM test1.user WHERE id = #{id}
    

5.2 second-user-mapper.xml

    
        
        
        
        
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

5.3 third-user-mapper.xml

    
        
        
        
        
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

6. 测试类

package com.zsx.test.mapper;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit.jupiter.SpringExtension;

@ExtendWith(SpringExtension.class)
@SpringBootTest
public class UserMapperTest {

    @Autowired
    @Qualifier("userMapper0")
    private  com.zsx.mapper.primary.UserMapper userMapper0;
    @Autowired
    @Qualifier("userMapper2")
    private com.zsx.mapper.second.UserMapper userMapper2;
    @Autowired
    @Qualifier("userMapper3")
    private com.zsx.mapper.third.UserMapper userMapper3;

    @Test
    void testFindById() {
        System.out.println(userMapper0.findById(1));
        System.out.println(userMapper2.findById(1));
        System.out.println(userMapper3.findById(1));
    }
}

7. 运行测试方法，查看测试结果

从结果看出配置数据源成功

二、配置动态数据源

1. pom.xml添加AOP依赖

            org.springframework.boot
            spring-boot-starter-aop
        

 

2. 添加数据库配置(DataBaseConfig.java)

@Bean(name="dynamicDataSource")
    public DataSource dynamicDataSource() {
        DynamicDataSource dynamicDataSource = new DynamicDataSource();
        DataSource primaryDataSource = primaryDataSource();
        //设置默认数据源
        dynamicDataSource.setDefaultTargetDataSource(primaryDataSource);
        //配置多数据源
        Map map = new HashMap<>();
        //key需要跟ThreadLocal中的值对应
        map.put("primaryDataSource", primaryDataSource);
        map.put("firstDataSource", firstDataSource());
        map.put("secondDataSource", secondDataSource());
        map.put("thirdDataSource", thirdDataSource());
        map.put("fourthDataSource", fourthDataSource());
        dynamicDataSource.setTargetDataSources(map);
        return dynamicDataSource;

3. 动态数据源配置

package com.zsx.config;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import javax.sql.DataSource;

@Configuration
@MapperScan(basePackages = {"com.zsx.mapper.dynamic"}, sqlSessionFactoryRef = "dynamicSqlSessionFactory")
public class MybatisDBDynamicConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(MybatisDBSecondConfig.class);

    @Bean(name = "dynamicSqlSessionFactory")
    public SqlSessionFactory dynamicSqlSessionFactory(@Qualifier("dynamicDataSource") DataSource dynamicDataSource) throws Exception {
        LOGGER.info("====================");
        LOGGER.info("dynamicDataSource=========" + dynamicDataSource);
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(dynamicDataSource);
        factoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/dynamic/*.xml"));
        return factoryBean.getObject();

    }

    @Bean(name = "dynamicSqlSessionTemplate")
    public SqlSessionTemplate dynamicSqlSessionTemplate(@Qualifier("dynamicSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean(name = "dynamicTransactionManager")
    public DataSourceTransactionManager dynamicTransactionManager(@Qualifier("dynamicDataSource") DataSource dynamicDataSource) {
        return new DataSourceTransactionManager(dynamicDataSource);
    }
}

4. 数据源

package com.zsx.config;

import com.zsx.holder.DataSourceContextHolder;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;

public class DynamicDataSource extends AbstractRoutingDataSource {

    private final static Logger LOGGER = LoggerFactory.getLogger(DynamicDataSource.class);

    @Override
    protected Object determineCurrentLookupKey() {
        LOGGER.debug("数据源为{}", DataSourceContextHolder.getDB());
        return DataSourceContextHolder.getDB();
    }

}

 5. 数据源上下文

package com.zsx.holder;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class DataSourceContextHolder {

    private final static Logger LOGGER = LoggerFactory.getLogger(DataSourceContextHolder.class);

    private final static ThreadLocal contextHolder = new ThreadLocal<>();

    // 设置数据源名
    public static void setDB(String dbType) {
        LOGGER.debug("切换到{}数据源", dbType);
        contextHolder.set(dbType);
    }

    // 获取数据源名
    public static String getDB() {
        return (contextHolder.get());
    }

    // 清除数据源名
    public static void clearDB() {
        contextHolder.remove();
    }
}

6. 创建注解接口

package com.zsx.annotation;

import java.lang.annotation.*;

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
@Documented
public @interface DS {

    String value() default "primaryDataSource";
}

7. 创建动态数据源切面

package com.zsx.aop;

import com.zsx.annotation.DS;
import com.zsx.holder.DataSourceContextHolder;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;


@Aspect
@Order(-1) // 该切面应当先于 @Transactional 执行
@Component
public class DynamicDataSourceAspect {

    private final static Logger LOGGER = LoggerFactory.getLogger(DynamicDataSourceAspect.class);

    @Before("@annotation(ds)")
    public void beforeSwitchDS(JoinPoint point, DS ds) {
        LOGGER.info("==========DynamicDataSourceAspect.beforeSwitchDS================");
        LOGGER.info("ds.value================" + ds.value());
        // 切换数据源
        DataSourceContextHolder.setDB(ds.value());

    }


    @After("@annotation(ds)")
    public void afterSwitchDS(JoinPoint point, DS ds) {
        LOGGER.info("==========DynamicDataSourceAspect.afterSwitchDS================");
        LOGGER.info("ds.value================" + ds.value());
        DataSourceContextHolder.clearDB();
    }
}

8. 编写数据接口

package com.zsx.mapper.dynamic;

import com.zsx.annotation.DS;
import com.zsx.entity.User;
import org.springframework.stereotype.Repository;

@Repository("userMapper1")
public interface UserMapper {

    @DS
    User findById(Integer id);

    @DS("firstDataSource")
    User findById1(Integer id);

    @DS("secondDataSource")
    User findById2(Integer id);

    @DS("thirdDataSource")
    User findById3(Integer id);

    @DS("fourthDataSource")
    User findById4(Integer id);
}

9. 添加对应的映射文件(resources\mybatis\mapper\dynamic\user-mapper.xml)

    
        
        
        
        
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

    
        SELECT id, name FROM user WHERE id = #{id}
    

10. 修改引导类

package com.zsx;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

/**
 * 通过配置多数据源，实现动态数据源切换
 * 禁用掉spring boot自带的数据源处理类DataSourceAutoConfiguration
 */
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@MapperScan(value = "com.zsx.dynamic.mapper")
public class SpringBootTemplateApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootTemplateApplication.class, args);
    }

}

11. 测试类

package com.zsx.test.mapper.dynamic;

import com.zsx.mapper.dynamic.UserMapper;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit.jupiter.SpringExtension;

@ExtendWith(SpringExtension.class)
@SpringBootTest
public class UserMapperTest {

    @Autowired
    @Qualifier("userMapper1")
    private UserMapper userMapper;

    @Test
    void testFindById() {
        System.out.println(userMapper.findById(1));
        System.out.println(userMapper.findById1(1));
        System.out.println(userMapper.findById2(1));
        System.out.println(userMapper.findById3(1));
        System.out.println(userMapper.findById4(1));
    }
}

12. 运行测试方法，查看测试结果
