在spring 的配置文件中添加配置
<!--配置Mapper扫描模式,所有Mapper都继承SqlMapper接口 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.lovo.mapper" />
<property name="markerInterface" value="com.lovo.mapper.SqlMapper" />
</bean>
包名为"com.lovo.mapper; 在包中有标志接口SqlMapper
package com.lovo.mapper;
public interface SqlMapper {
}
所有的mapper 继承于标志接口
public interface OutContractMapper extends SqlMapper {
.....................................
}
一、查询
1、
@Select("select * from c_cbdcarport limit #{param1},#{param2}")
@Results(value={
@Result(property="id",column="id",id=true),
@Result(property="address",column="address"),
@Result(property="carportnumber",column="carportnumber"),
@Result(property="areanumber",column="areanumber"),
@Result(property="status",column="status"),
})
public List<CBDCarportEntity> getAllCdbcarport(int pageNum,int rowNum);
2、
@Select("select count(*) as rows from c_cbdcarport")
@ResultType(value=int.class)
public int getRows();
3、
@Select("<script>"
+ " select count(*) as rows from c_contract where 1=1 "
+ "<if test=\"param1 != null and param1 !=‘‘\">"
+ "and contractnumber like concat(‘%‘,#{param1},‘%‘) "
+ "</if>"
+ "<if test=\"param2 != null and param2 !=‘‘\">"
+ "and startTime >= #{param2} "
+ "</if>"
+ "<if test=\"param3 != null and param3 !=‘‘\">"
+ "and endTime <= #{param3} "
+ "</if>"
+ "</script>")
@ResultType(value = int.class)
public int getRows(String number,String startTime,String endTime);
4、
@Select("<script>"
+"select * from c_publishinfo where status=‘0‘"
+ "<if test=\"param1!=null and param1 !=‘‘\">"
+ "and starttime >=#{param1}"
+"</if>"
+"<if test=\"param2 !=null and param2 !=‘‘\">"
+"and endtime <=#{param2}"
+"</if>"
+ " limit #{param3},#{param4}"
+"</script>")
@Results(value={
@Result(property="id",column="id",id=true),
@Result(property="address",column="address"),
@Result(property="carportnum",column="carportnumber"),
@Result(property="permitnumber",column="permitnumber"),
@Result(property="carportpic",column="carportpic"),
@Result(property="starttime",column="starttime"),
@Result(property="endtime",column="endtime"),
@Result(property="price",column="price"),
@Result(property="status",column="status"),
@Result(property="lender_id",column="lender_id"),
@Result(property="time",column="time"),
@Result(property="lender",column="lender_id",
[email protected](select="com.lovo.mapper.LenderMapper.getLenderEntityById"))
})
public List<PublishinfoEntity> getAllPublish(String starttime,String endtime,int page,int pageSize);
二、添加
@Insert("insert into c_cbdcarport values(null,#{address},#{carportnumber},#{areanumber},#{status},null,null)")
@Options(useGeneratedKeys=true,keyProperty="id")
public void addCdbcarport(CBDCarportEntity Cdbcarport);
三、删除
@Delete("delete from c_cbdcarport where id = #{id}")
public void delCdbcarportById(int id);
四、修改
@Update("update c_cbdcarport set address=#{address},carportnumber=#{carportnumber}"
+",areanumber=#{areanumber},status=#{status} where id=#{id}")
public void updateCdbcarport(CBDCarportEntity Cdbcarport);
