MyBatis 不支持布尔映射

我只是想用 Mybatis 映射布尔值，但遇到问题。首先我给大家展示一下涉及到的部分：

XML File:

<resultMap id="destinationTypeMap" type="DestinationTypeDTO">
        <result property="destinationTypeId" column="education_destination_type_id" javaType="java.lang.Long" jdbcType="NUMERIC"/>
        <result property="description" column="description" javaType="java.lang.String" jdbcType="VARCHAR"/>
        <result property="available" column="is_available" javaType="boolean" jdbcType="VARCHAR" typeHandler="BooleanHandler"/>
    </resultMap>

Java类：

public class DestinationTypeDTO {

    private long destinationTypeId;
    private String description;
    private boolean available;

    public long getDestinationTypeId() {
        return destinationTypeId;
    }

    public void setDestinationTypeId(long destinationTypeId) {
        this.destinationTypeId = destinationTypeId;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public boolean isAvailable() {
        return available;
    }

    public void setAvailable(boolean available) {
        this.available = available;
    }

}

但是，我收到此错误日志：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Could not set property 'isAvailable' of '....DestinationTypeDTO@bbd76bf' with value 'true' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'isAvailable' in 'class ....DestinationTypeDTO'

我花了几个小时试图找出发生了什么，但没有成功。有什么提示吗？

感谢大家。

Change javaType="boolean" to java.lang.Boolean并指定property="available"

<result property="available" column="is_available" property="available" javaType="java.lang.Boolean" jdbcType="VARCHAR" typeHandler="BooleanHandler"/>

在你的班级改变private boolean available; to private Boolean isAvailable;并添加 getter/setter

public void setIsAvailable(Boolean available) {
    this.available = available;
}

public Boolean getIsAvailable() {
    return available;
}
