使用java和spark处理API路由异常

Question

我有一个带有POST，PATCH，GET和DELETE路由的API。而且我必须在每个中创建try catch块以捕获各种可能的错误。我目前正在调用错误类

StandardError standardError = new StandardError("415");

package domainObjects;

import com.google.gson.annotations.Expose;

public class StandardError {

    @Expose
    String status;

    @Expose
    String source;

    @Expose
    String detail;

    public StandardError(String errorCode){
        switch(errorCode) {

        case "409":
            this.status = "409";
            this.source = "/suppliers/";
            this.detail = "Resource already exists";
            break;
        case "500":
            this.status = "500";
            this.source = "/suppliers/";
            this.detail = "Unknown Error";
            break;
        case "415":
            this.status = "415";
            this.source = "/suppliers/";
            this.detail = "Unsupported media type. Content Type: application/vnd.api+json required.";
            break;
        case "404":
            this.status = "404";
            this.source = "/suppliers/";
            this.detail = "Resource does not exist";
            break;

        }
    }

问题是每个路由方法都有大量复制。

spark上的Exception Mapping部分描述了捕获异常的以下路径。问题是这只是捕获一个特殊异常，我需要抓住很多。

我是否需要为每个例外创建一个新的例外路由，或者我可以使用get("/throwexception", (request, response) -> {处理所有错误吗？

get("/throwexception", (request, response) -> {
    throw new YourCustomException();
});

exception(YourCustomException.class, (exception, request, response) -> {
    // Handle the exception here
});
