使用Spring测试在lambda表达式中发生异常

Question

我有一个DAO实现，它使用Lambada表达式如下所示：

public RowMapper<User> getRowMapper() {
        return (rs, rowNum) -> {
            User result = new User();

            result.setUid(rs.getInt("uid"));

            return result;
        };
    }

当我使用gradle build时，异常消息显示如下：

ParseException in STDIN
Last useful checkpoint: "com.xx.daoimpl.MyDaoImpl.getRowMapper()"
Encountered " "," ", "" at line 61, column 27.

    ">" ...
    ">" ...
    ">" ...
    ">" ...
    "<" ...
    "<" ...
    ")" ...
    "<" ...

它指的是(rs, rowNum) .But中的“，”，当我使用gradle assemble时，它工作得很好，这意味着当测试用例使用它时发生了一些事情。我正在使用Spring的嵌入式数据库进行测试。

有人能帮忙吗？

我不确定这是否是同一个问题，但您是否正在使用JavaNCSS呢？

我在使用cobertura时也会遇到同样的错误，正如这里所解释的，在JavaNCSS中，这是一个问题，无法很好地处理java 8。

我希望这能帮到你
