Code Snippet:

Answer 1

LineBreak不是标准的Grails编解码器，因此请确保在grails / utils文件夹中正确定义了自定义编解码器。

class LineBreakCodec {
    static encode = { str ->
        // convert the string and return the result
    }
}

请参阅11.2末尾的自定义编解码器部分 http://grails.org/doc/latest/guide/single.html#11.2%20Encoding%20and%20Decoding%20Objects

没有方法签名：java.lang.String.encodeAsLineBreak（）groovy / grails
