Mybatis查询sql传入一个字符串传参数，报There is no getter for property named ‘ids‘ in ‘class java.lang.String‘。
解决方法：
1.在接口参数里加上mybatis中的@param注解
@MyBatisDao public interface OfficeDao extends TreeDao<Office> { List<Office> findCompanyNameList（@Param("name")String name); }
<select id="findCompanyNameList" parameterType="java.lang.String" resultType="com.pds.modules.sys.entity.Office"> SELECT id,name FROM sys_office where o.del_flag = ‘1‘ <if test="name!= null and name!= ‘‘"> AND name LIKE concat(‘%‘,#{name},‘%‘) </if> </select>
2.在xml的if里用"_parameter" 代表参数，
<select id="findCompanyNameList" parameterType="java.lang.String" resultType="com.pds.modules.sys.entity.Office"> SELECT id,name FROM sys_office where o.del_flag = ‘1‘ <if test="_parameter!= null and _parameter!= ‘‘"> AND name LIKE concat(‘%‘,#{name},‘%‘) </if> </select>
或无论参数名是啥，都要改成"_parameter"
<select id="findByName" parameterType="string" resultType="com.domain.entity.FactoryEntity"> SELECT * FROM T_FACTORY WHERE F_NAME LIKE "%${_parameter}%" </select>
两种方法区别
可以看出，_parameter不能区分多个参数，而@param能。所以@param能传多个这样的参数
3.将String参数放入Map集合中
Map map=new HashMap(); map.put("condition",condition); List list=bookMapper.bookList(map);
<select id="bookList" parameterType="map" resultMap="BaseResultMap"> select <include refid="Base_Column_List" /> from book <if test="condition!= null"> where bname like ‘%${condition}%‘ or author like ‘%${condition}%‘ </if> </select>
