Question

我有一个自定义异常类customException，当调用它时需要三个参数（两个整数和String）。

目前在我的camel.xml文件中我有：

na.omit(ames_test)

抛出异常时，我想要的特定变量为null。如何在Camel中设置该变量？有可能吗？

您可以将异常定义为具有自定义构造函数参数和属性值的单独bean，并从i引用它：

  handler: (request, reply) => {
            const query = request.query;
            const quoteNum = request.query.QuoteNum;
            let numOfQuotes = request.query.NumOfQuotes;
            let filterType = request.query.Filter;
            const beginDate = request.query.StartDate;
            const endDate = request.query.EndDate;
            const optionsType = request.query.MoreOptionsType;
            const optionsQuery = request.query.moreOptionsQuery;
            const optionsValue = request.query.MoreOptionsString;
            switch (numOfQuotes) {
                case '100':
                    numOfQuotes = "SELECT TOP 100";
                    break;
                case '200':
                    numOfQuotes = "SELECT TOP 200";
                    break;
                case '500':
                    numOfQuotes = "SELECT TOP 500";
                    break;
                case '1000':
                    numOfQuotes = "SELECT TOP 1000";
                    break;
                case '2000':
                    numOfQuotes = "SELECT TOP 2000";
                    break;
                case '5000':
                    numOfQuotes = "SELECT TOP 5000";
                    break;
                case '10000':
                    numOfQuotes = "SELECT TOP 10000";
                    break;
                case 'ALL':
                    numOfQuotes = "SELECT";
                    break;
                default:
                    numOfQuotes = "SELECT TOP 50";
            }
            if (filterType != '') {
                switch (filterType) {
