sprintboot+mybatis+@Mapper中in的使用方法

錯誤的使用方法：

 @Select("select goods_sn from ${tableName} where goods_sn in (#{skuStr})")
 public List<String> selectForAlgorithm(@Param("skuStr") String skuStr,@Param("tableName") String tableName);

正確的使用方法：

 @SelectProvider(type = DWebsiteProvider.class,method="selectForAlgorithm")
 public List<String> selectForAlgorithm(@Param("skuStr") String skuStr,@Param("tableName") String tableName);

之后在DWebsiteProvider類中添加如下方法：

  public String selectForAlgorithm(String skuStr,String tableName){
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("select goods_sn from "+tableName+" where goods_sn in ("+skuStr+");");
        return stringBuilder.toString();
    }
