问题描述
我已经使用Spring Boot开发了rest API。
现在，我使用邮递员使用格式错误的网址（如ValueError: in user code:

我得到的回应是
http://localhost:8080/DD%/jhsj5/我想修改响应，就像我为NohandlerfoundException修改的一样，如下所示
<!doctype html>
<html lang="en"><head><title>HTTP Status 400 – Bad Request</title>
<style type="text/css">
body {font-family:Tahoma,Arial,sans-serif;}
h1,h2,h3,b {color:white;background-color:#525D76;}
h1 {font-size:22px;}
h2 {font-size:16px;}
h3 {font-size:14px;}
p {font-size:12px;}
a {color:black;}
.line {height:1px;background-color:#525D76;border:none;}
</style>
</head>
<body>
<h1>HTTP Status 400 – Bad Request</h1>
</body>
</html>
但如果{
"status": 404,"message": "","error": "Invalid url Path"
} .
上方的网址行格式错误，则在我的代码中不会引发任何异常。
那么如何处理呢？
解决方法
github issue 对此有异议，它包含 sc-moonlight 发布的以下工作：
@Bean
public TomcatWebSocketServletWebServerCustomizer errorValveCustomizer() {
return new TomcatWebSocketServletWebServerCustomizer() {
@Override
public void customize(TomcatServletWebServerFactory factory) {
factory.addContextCustomizers((context) -> {
Container parent = context.getParent();
if ( parent instanceof StandardHost) {
((StandardHost) parent).setErrorReportValveClass("aaa.bbb.ccc.configuration.CustomTomcatErrorValve");
}
});
}
@Override
public int getOrder() {
return 100; // needs to be AFTER the one configured with TomcatWebServerFactoryCustomizer
}
};
}
和
package aaa.bbb.ccc;
public class CustomTomcatErrorValve extends ErrorReportValve{
private static final Logger LOGGER = LoggerFactory.getLogger(CustomTomcatErrorValve.class);
protected void report(Request request,Response response,Throwable throwable) {
if (!response.setErrorReported())
return;
LOGGER.warn("{} Fatal error before getting to Spring. {} ",response.getStatus(),errorCode,throwable);
try {
Writer writer = response.getReporter();
writer.write(Integer.toString(response.getStatus()));
writer.write(" Fatal error. Could not process request.");
response.finishResponse();
} catch (IOException e) {
}
}
}
