@Primary代表默认的数据源

@Configuration
public class DataSourceConfig {
@Bean(name = "AdDataSource")
@Qualifier("AdDataSource")
@Primary
@ConfigurationProperties(prefix="spring.datasource.ad")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "MaopaoDataSource")
@Qualifier("MaopaoDataSource")
@ConfigurationProperties(prefix="spring.datasource.maopao")
public DataSource secondaryDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name="AdJdbcTemplate")
public JdbcTemplate primaryJdbcTemplate (
@Qualifier("AdDataSource") DataSource dataSource ) {
return new JdbcTemplate(dataSource);
}
@Bean(name="MaopaoJdbcTemplate")
public JdbcTemplate secondaryJdbcTemplate(
@Qualifier("MaopaoDataSource") DataSource dataSource) {
return new JdbcTemplate(dataSource);
}
}
使用示例:
想使用哪个数据库 就在@Qualifier 里面更换不同的bean名称即可
@Autowired
@Qualifier("AdJdbcTemplate")
JdbcTemplate jdbcTemplate;
