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>
