详解Springboot之整合JDBCTemplate配置多数据源
一、前言
现在在我们的项目中,使用多数据源已经是很常见的,下面,这里总结一下springboot整合jdbcTemplate配置多数据源的代码示例,以方便以后直接使用.
二、配置文件
spring: datasource: datasourceone: driverClassName: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/eesy?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false username: root password: root dataSourcetwo: driverClassName: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/eesy?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false username: root password: root
三、数据源配置类
package com.ssl.datasource.config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties; 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 org.springframework.jdbc.core.JdbcTemplate; import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate; import javax.sql.DataSource; @Configuration public class DataSourceOne { @Bean("name-template-one") public NamedParameterJdbcTemplate namedParameterJdbcTemplate(@Qualifier("datasource-one") DataSource dataSource){ return new NamedParameterJdbcTemplate(dataSource); } @Bean("template-one") public JdbcTemplate jdbcTemplate(@Qualifier("datasource-one") DataSource dataSource){ return new JdbcTemplate(dataSource); } @Bean("datasource-one") public DataSource dataSource(@Qualifier("jdbc-config-one") DataSourceProperties dataSourceProperties){ return dataSourceProperties.initializeDataSourceBuilder().build(); } @Primary @Bean("jdbc-config-one") @ConfigurationProperties(prefix = "spring.datasource.datasourceone") public DataSourceProperties properties(){ return new DataSourceProperties(); } }
package com.ssl.datasource.config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties; 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 org.springframework.jdbc.core.JdbcTemplate; import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate; import javax.sql.DataSource; @Configuration public class DataSourceTwo { @Bean("name-template-two") public NamedParameterJdbcTemplate namedParameterJdbcTemplate(@Qualifier("datasource-two") DataSource dataSource){ return new NamedParameterJdbcTemplate(dataSource); } @Bean("template-two") public JdbcTemplate jdbcTemplate(@Qualifier("datasource-two") DataSource dataSource){ return new JdbcTemplate(dataSource); } @Bean("datasource-two") public DataSource dataSource(@Qualifier("jdbc-config-two") DataSourceProperties dataSourceProperties){ return dataSourceProperties.initializeDataSourceBuilder().build(); } @Bean("jdbc-config-two") @ConfigurationProperties(prefix = "spring.datasource.datasourcetwo") public DataSourceProperties properties(){ return new DataSourceProperties(); } }
