我正在使用 Spring MVC 3.2 @RequestMapping 和 @ResponseBody 作为 REST 服务。示例端点如下所示:
@RequestMapping(value = "query", method = RequestMethod.GET)
@ResponseBody
public Locations searchHandler(@RequestParam String q, HttpServletRequest request, HttpServletResponse response) {
...
为不存在的端点发送错误请求或缺少 GET 参数 q 将显示 Tomcat 7 错误报告:
<html>
<head>
<title>Apache Tomcat/7.0.50 - Error report</title>
<style>
<!--H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background:white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;}-->
</style>
</head>
<body>

<HR size="1" noshade="noshade">

<p>

</p>
<HR size="1" noshade="noshade">

</html>
如何禁用此错误页面。我只希望将错误消息作为没有任何 HTML 或更多信息的内容。
最佳答案
好的，我找到了解决方案。我按照上面的链接中的描述实现了一个异常处理程序:
@ControllerAdvice
public class ErrorController {
/**
* .
* @param request .
* @param response .
* @throws Exception .
*/
@ExceptionHandler(Exception.class)
public void handleConflict(HttpServletRequest request, HttpServletResponse response, Exception e) throws Exception {
// If the exception is annotated with @ResponseStatus rethrow it and let
// the framework handle it - like the OrderNotFoundException example
// at the start of this post.
// AnnotationUtils is a Spring Framework utility class.
if (AnnotationUtils.findAnnotation(e.getClass(), ResponseStatus.class) != null) {
throw e;
}
response.setStatus(400);
response.getWriter().println(e.getMessage());
}
}
重要的是使用 response.getWriter()... 而不是 response.sendError()。
关于java - 在 Tomcat 中为 Spring MVC REST API 禁用默认错误页面，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21904818/
