如何使用Angular UI转换JHipster App中的自定义错误消息?
我添加了自定义异常处理程序:
@ExceptionHandler
default ResponseEntity<Problem> handleSomeBusinessException(final SomeBusinessException exception, final NativeWebRequest request) {
final Problem problem = Problem.builder()
.withStatus(UNPROCESSABLE_ENTITY)
.with("BusinessException", SomeBusinessException .class.getName())
.with("BusinessMessage", exception.getMessage())
.build();
return create(exception, problem, request);
}
接下来,我修改了 alert-error.component.ts
this.httpErrorListener = eventManager.subscribe('someApp.httpError', (response: JhiEventWithContent<HttpErrorResponse>) => {
const httpErrorResponse = response.content;
switch (httpErrorResponse.status) {
case 422:
this.addErrorAlert(httpErrorResponse.error.BusinessMessage);
break;
不幸的是,当我运行应用程序并抛出 SomeBusinessException 时,我在UI中看到以下内容:
translation-not-found [一些与 SomeBusinessException]
您能建议我在哪里介绍我的 BusinessMessage 的翻译吗?
更新: 我检查了src \ main \ webapp \ i18n \ en \ error.json,但它绑定到http.code,而不是消息本身

可以使用简单的异常名称来完成。另外,您可以传递参数,以 ngx-translate 代替。
首先,您需要在问题中传递自定义参数:
@ExceptionHandler
default ResponseEntity<Problem> handleSomeBusinessException(final SomeBusinessException exception, final NativeWebRequest request) {
final Problem problem = Problem.builder()
.withStatus(UNPROCESSABLE_ENTITY)
.with("businessException", SomeBusinessException.class.getSimpleName())
.with("parameterKey", "some value goes here")
.build();
return create(exception, problem, request);
}
第二个是 AlertErrorComponent 的构造函数:
constructor(private alertService: JhiAlertService, private eventManager: JhiEventManager, translateService: TranslateService) {
...
switch (httpErrorResponse.status) {
...
case 422:
this.addErrorAlert('', 'business.' + httpErrorResponse.error.businessException, httpErrorResponse.error);
break;
第三项是提供带有参数的翻译( ngx-translate 支持):
src / main / webapp / i18n / en / error.json
{
"business": {
"SomeBusinessException ": "Translated text goes here. {{parameterKey}}",
}
...
}
{{parameterKey}} 将由 ngx-translate 替换为“有些值在这里”
所以您将在屏幕上看到以下消息:
翻译后的文字在这里。这里有些价值
