SpringBoot配置多数据源 springBoot代码缓存新手爬坑

首先代码初始化到内存(加载两个不同url链接下的两个库一个是postgre库一个是gp库)

配置文件 application.properties(要注意前缀要严格按照该模板如driver-calss-name -不能省)

mybatis.type-aliases-package=com.thunisoft.zsjinterface
server.port:8090

spring.datasource.test1.driver-class-name: net.sf.log4jdbc.sql.jdbcapi.DriverSpy

配置对应的mapper 1

package com.thunisoft.zsjinterface.dao.base;

import org.apache.ibatis.annotations.*;

import java.util.List;

@Mapper
public interface YsjDao {
    @Select(value = "SELECT t.c_name as wbjname, m.c_name as bname FROM db_ysjgl.t_sjkjgxxb K "
            + "LEFT JOIN db_ysjgl.t_sjkbjgxxb b ON K .c_bh = b.c_sjkjgxxb_id "
            + "LEFT JOIN db_ysjgl.t_mlxxglb m ON b.c_bh=m.c_sjk_id "
            + "LEFT JOIN db_ysjgl.t_mlxxb t ON m.c_mlxxb_id=t.c_bh "
            + "WHERE b.c_bh=#{sjlybh}")
    @Results({@Result(property = "WbjName", column = "wbjname"), @Result(property = "BName", column = "bname")})
    public YsjPojo selectAll(@Param("sjlybh") String sjlybh);

    @Select(value ="SELECT c_zdmc,c_dmlx FROM db_jcwzsj.t_zsjbxx " )
    @Results({@Result(property = "zdmc", column = "c_zdmc"), @Result(property = "dmlx", column = "c_dmlx")})
    public List<Zsjbxx>  selectGet();
}

配置mapper2

        import java.util.List;

@Mapper

    public List<Dm> selectAll();
}
