Handling RequestRejectedException - ExceptionLoggingFilter

I was getting this error when a user was missing a parameter in the request and it was coming like www.foo.com/fooId//info and it was throwing a RequestRejectedException and returning a 500 error to the user.
Error Log:
o.s.c.s.i.web.ExceptionLoggingFilter : Uncaught exception thrown
org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL was not normalized.

To catch this exception, I added this filter:
#Component
#Slf4j
#Order(Ordered.HIGHEST_PRECEDENCE)
public class RequestRejectedExceptionHandler extends OncePerRequestFilter {
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
try {
filterChain.doFilter(request, response);
} catch (RequestRejectedException e) {
log.error("400 - Bad Request");
response.setStatus(400);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
}
}
}
In postman now, it is returning a 400 bad request as I want it to, however in my logs, I can see this ERROR still being logged as uncaught, and not too sure why and need some advice:

You are likely using an unsupported version of Spring Cloud Sleuth if you are seeing these logs.
The logs from o.s.c.s.i.web.ExceptionLoggingFilter are coming from the Spring Cloud Sleuth dependency.
The ExceptionLoggingFilter is intended to help with log correlation. From the reference documenation
Sleuth configures the logging context with variables including the service name (%{spring.zipkin.service.name}) and the trace ID (%{traceId}). These help you connect logs with distributed traces and allow you choice in what tools you use to troubleshoot your services.
Once you find any log with an error, you can look for the trace ID in the message.
In this case, the ExceptionLoggingFilter is likely executed before your custom filter.
Note that the ExceptionLoggingFilter is disabled by default since Spring Cloud Sleuth 2.2.3 and removed completely in 3.x.
If you upgrade to a supported version of Sleuth, you will not see these logs.

With 3.1.x we are adding support for Tomcat Valve instrumentation so that ExceptionLoggingFilter is no longer needed. We will instrument all logs that come from within tomcat.

Thymeleaf not able to find template in spring boot project

I want to do a very simple thing, when an API "localhost:8080/my-project/success" is called, it should return an html template that is in "resources/templates" folder in my Spring Boot Project. But it gives me this error:
Controller:
#Controller
public class MessageController {
#GetMapping(value = "/success", produces = MediaType.TEXT_HTML_VALUE)
public String callback() {
return "success_message";
}
}
HTML template location:
HTML Template Code:
<!DOCTYPE html SYSTEM "http://www.thymeleaf.org/dtd/xhtml1-strict-thymeleaf-spring4-4.dtd">
<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">

I have tried every other solution on SO related to this. Most of them can be categorized in below 2 categories:
Created a separated Config class for thymeleaf ((set classpath to 'classpath:/templates/', set suffix as HTML etc).
Added config for thymeleaf in application.properties instead (set classpath to 'classpath:/templates/', set suffix as HTML same thing as point 1).
Nothing has worked, I doubt if above config would be required in a spring boot project at all because all of this is auto-configured as soon as we import spring-boot-starter-thymeleaf dependency.
A lot of other issues on SO are related to naming, missing a slash, not keeping template in /resources/templates. But I think I got that part right.
There are other projects where I have used thymeleaf for same (literally same use case) purpose. It works fine in them. I created a new Spring Boot project to test and it works in that too.
If needed, these are all 3 of the config files used:
First Config
#Configuration
#RequiredArgsConstructor
public class Config1 implements WebMvcConfigurer {
private final SomeInterceptor someInterceptor;
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(someInterceptor)
.addPathPatterns("/**/path-not-related-to-success-api/**");
}
}
Second Config
#Configuration
public class Config2 {
#Value("${connectionTimeOut}")
private int connectionTimeOut;
#Value("${readTimeOut}")
private int readTimeOut;
#Bean
public RestTemplate getRestTemplate() {
RestTemplateBuilder restTemplateBuilder = new RestTemplateBuilder();
return restTemplateBuilder
.setConnectTimeout(Duration.ofSeconds(connectionTimeOut))
.setReadTimeout(Duration.ofSeconds(readTimeOut))
.additionalCustomizers(
new RestTemplateStandardCookieCustomizer()
)
.build();
}
}
Third Config (not a config exactly, but it is used in second config file)
public class RestTemplateStandardCookieCustomizer implements RestTemplateCustomizer {
#Override
public void customize(RestTemplate restTemplate) {
final HttpClient httpClient = HttpClients.custom()
.setDefaultRequestConfig(RequestConfig.custom()
.setCookieSpec(CookieSpecs.STANDARD).build())
.build();
restTemplate.setRequestFactory(
new HttpComponentsClientHttpRequestFactory(httpClient)
);
}
}

I asked the question originally. Could not solve above issue. But as a work around, I did following:
removed thymeleaf dependency
Changed the controller to something like this:
#Controller
public class MessageController {
#GetMapping(value = "/success", produces = MediaType.TEXT_HTML_VALUE)
#ResponseBody
public String callback() {
return "<html>...</html";
}
}
In the above code, I changed 2 things - added #ResponseBody and instead of giving the HTML template name as return value, pasted the whole HTML as a text. Not a very ideal way to do, but as my template is small and fixed, it seems alright.
Also, I removed thymeleaf related tags from HTML, like xmlns and th tags.
There was no need for success_message.html in templates folder so that can be deleted.

Improve this question
I'm creating a webservice, but when I call the http://localhost:8080/mdn/add endpoint, I'm getting a stacktrace, even though I expected that the JSON data would be stored in my database.
This is the entity class:
#Entity
#Table(name = "abctable")
public class AbcEntity{
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
private int id;
#Column(name = "mndt")
private String mndt;
#Column(name ="cdate")
private Date cdate;
#Column(name= "cno")
private String cno;
#Column(name = "customer")
private String customer;
#Column(name ="Customer_Name")
private String customer_name;
}
This is the controller:
#RestController
#RequestMapping(value ={"/mdn"})
public class MdnBController {
#Autowired
MdnBRepository mdnbrepos;
#PostMapping(value = "/add",produces = MediaType.APPLICATION_JSON_VALUE,consumes=MediaType.APPLICATION_JSON_VALUE)
public AbcEntity addDetails(#RequestBody AbcEntity mdnentity)
{
return mdnbrepos.save(mdnentity);
}
All other related classes are also present. This is the JSON input I'm trying to send as a request body:
{
"mndt": "300",
"cdate": "20190114",
"cno": "999999",
"customer": "00002005",
"customer_name": "cus2"
}
However, when I execute this request, I get the following stacktrace:
nested exception is java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.JavaType.isReferenceType()Z] with root cause

You have a mixed versions of Jackson dependencies on your classpath. Looking at your stack trace we see both jackson-databind-2.5.3 and jackson-datatype-jdk8-2.9.7.jar. spring-web-5.1.3.RELEASE depends on jackson-databind-2.9.7 so use this version and remove 2.5.3.

MongoDb Criteria Query LTE not working for numeric

query.addCriteria(Criteria.where(x.getKey()).lte(3));
lte method accepting an array or array list or string parameter. the parameter type is Object so it should accept numeric object but it is not. query won't return any results if I have passed any other types. It should be numeric but I am getting a weird error.

Spring Reactive consume POST using FLUX or MONO

How to consume a POST or PUT using Mono or Flux from method parameter. Let us say I've EmployeeApi interface defined as shown below, where creating a employee object using Mono
#RequestMapping("${v1Api}/employee")
public interface EmployeeApi {
#GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
Flux<ResponseEntity<Employee>> list();
#PostMapping(consumes = MediaType.APPLICATION_JSON_VALUE)
Mono<ResponseEntity<Void>> create(#Valid Mono<Employee> employee);
}
Implementation method.
#Override
public Mono<ResponseEntity<Void>> create(#Valid Mono<Employee> emp) {
emp.doOnNext(e->System.out.println(e.getEmpId()));
return Mono.empty();
}
Getting below error

Though It can be done using ServerRequest object as shown below.
public Mono<ServerResponse> create(ServerRequest request) {
Mono<Employee> emp= request.bodyToMono(Employee.class).doOnNext(e-> System.out.println(e.getEmpId());
return ok().build(repository.save(emp));
}
But Is there a way to consume directly using Mono or Flux?

The stacktrace shows that your application isn't using Spring WebFlux but actually Spring MVC. As explained in the reference documentation, Spring MVC only supports reactive types as return values, not as method arguments.
Also, note that the Flux<ResponseEntity<Employee>> doesn't make sense since a single endpoint cannot return several HTTP responses - Flux represents a 0..N cardinility; Mono is more appropriate in that case.
