MyBatis-Oracle-selectKey返回主键

插入类目记录，并返回category_id，其中category_id是根据自定义规则生成的

<insert id="insertSelective2" parameterType="com.imooc.model.ProductCategory">
    insert into product_category(<include refid="Base_Save_List"/>)
    values (#{productCategory.categoryName,jdbcType=VARCHAR},#{productCategory.categoryType,jdbcType=INTEGER})

    <selectKey keyProperty='productCategory.categoryId' resultType='int' order='AFTER' >
        select MAX(category_id) from product_category
    </selectKey>
</insert>

使用方法

public Integer save(ProductCategory productCategory) {
    System.out.println(categoryMapper.insertSelective2(productCategory));
int categoryId = productCategory.getCategoryId;
    return categoryId;
}

上述代码实现了将MAX(category_id)存入'productCategory.categoryId，供大家参考
