application.yml

mapper及model

package com.ydfind.start.dao;
import com.ydfind.start.model.ConfigItem;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import java.util.List;
@Mapper
public interface ConfigMapper {
    @Select("select id, name, item_key itemKey, item_value itemValue" +
            " from op_config where name=#{name}")
    List<ConfigItem> getConfigByName(String name);
 }
package com.ydfind.start.model;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
public class ConfigItem {
    @ApiModelProperty(value = "id")
    private Long id;
    @ApiModelProperty(value = "配置名称")
    private String name;
    @ApiModelProperty(value = "项key")
    private String itemKey;
    @ApiModelProperty(value = "项值")
    private String itemValue;
}

入口

添加注解
@ComponentScan({“com.ydfind.start”, “com.ydfind.common”})
//@MapperScan(“com.cmbchina.www.rec.dao”)

建表

CREATE TABLE [manager].dbo.op_config (
    id bigint NOT NULL,
    name varchar(128) COLLATE Chinese_PRC_CI_AS NOT NULL,
    item_value varchar(128) COLLATE Chinese_PRC_CI_AS NOT NULL,
    item_key varchar(64) COLLATE Chinese_PRC_CI_AS NULL,
    description varchar(128) COLLATE Chinese_PRC_CI_AS NULL,
    CONSTRAINT PK_op_config PRIMARY KEY (id)
)

测试

package com.ydfind.start.mapper;
import com.ydfind.start.BaseTest;
import com.ydfind.start.dao.ConfigMapper;
import com.ydfind.start.model.ConfigItem;
import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runners.MethodSorters;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.List;
@FixMethodOrder(MethodSorters.DEFAULT)
public class ConfigMapperTest extends BaseTest {
    @Autowired
    private ConfigMapper configMapper;
    @Test
    public void testGetConfigs() {
        List<ConfigItem> items = configMapper.getConfigByName("AUTO_PUSH");
        System.out.println(items);
    }
}
