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.
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
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();
}
}
