Hikari数据源配置

核心配置类

import javax.sql.DataSource;

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.util.StringUtils;

import com.zaxxer.hikari.HikariDataSource;

@Configuration
public class DataSourceConfig {
	
    @Primary
    @Bean(name = "hikariDataSourceProperties")
    @ConfigurationProperties(prefix = "spring.datasource.datasource2")
    public DataSourceProperties hikariDataSourceProperties() {
        return new DataSourceProperties();
    }
	
    @Bean(name = "hikariDataSource")
    @ConfigurationProperties(prefix = "spring.datasource.datasource1")
    public DataSource hikariDataSource() {
        DataSourceProperties properties =  this.hikariDataSourceProperties();
        return createHikariDataSource(properties);
    }

    private static HikariDataSource createHikariDataSource(DataSourceProperties properties) {
        // 创建 HikariDataSource 对象
        HikariDataSource dataSource = properties.initializeDataSourceBuilder().type(HikariDataSource.class).build();
        // 设置线程池名
        if (StringUtils.hasText(properties.getName())) {
            dataSource.setPoolName(properties.getName());
        }
        return dataSource;
    }

}
