我是靠谱客的博主狂野灯泡，这篇文章主要介绍java.lang.IllegalArgumentException: argument type mismatch Mybaitis 一对多映射报错，现在分享给大家，希望可以做个参考。

报错原因：

映射的子集合如果有字段与上级字段相同，一定要设置别名；
resultReMap 映射的实体类，如果设置了有参构造，一定要定义一个空参构造。

业务代码示例
resultReMap

    <resultMap id="EleResultMap" type="com.xxx.xxx.xxx.xxx.ElementTree">
        <id column="id" jdbcType="BIGINT" property="id"/>
        <result column="name" jdbcType="VARCHAR" property="name"/>
        <collection property="childrens" notNullColumn="eleId,eleName" ofType="com.sumgrowpower.checkpricing.base.dto.ElementTree">
          <result column="eleId" jdbcType="BIGINT" property="id" />
          <result column="eleName" jdbcType="VARCHAR" property="name" />
        </collection>
    </resultMap>

查询sql

  <select id="selectEleTree" parameterType="java.lang.String" resultMap="EleResultMap">
      select t.id,t.name,ti.id as eleId,ti.name as eleName from `tableName_1` t left join `tableName_2` ti
      on ti.category_id = t.id
  </select>

映射实体类 ElementTree

public class ElementTree {
    private Long id;
    private String name;
    private List<ElementTree> childrens;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<ElementTree> getChildrens() {
        return childrens;
    }

    public void setChildrens(List<ElementTree> childrens) {
        this.childrens = childrens;
    }
    //定义了有参构造，一定要加空参构造！！
    public ElementTree() {
        super();
    }
    public ElementTree(Long id, String name, List<ElementTree> childrens) {
        super();
        this.id = id;
        this.name = name;
        this.childrens = childrens;
    }

    @Override
    public String toString() {
        return "ElementTree{" +
                "id=" + id +
                ", name='" + name + ''' +
                ", childrens=" + childrens +
                '}';
    }
}

结果展示

            "id": 1,
            "name": "建材类",
            "childrens": [

            ]

                {

                {

                }
            ]
        }
