spring-web

I'm using spring-boot and added spring-web dependency in maven pom, to make use of RestTemplate . Now spring tries to initialize an EmbeddedServletContext . How can I prevent it? Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean. at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:133)

I have this Spring REST controller method: @ApiOperation("My method") @RequestMapping(method = RequestMethod.POST, value = "/myMethod") public void myMethod(@RequestParam("myParam") String myParam) { ... } The REST client is generated using swagger codegen CLI with language Java and library resttemplate : public void myMethod(String myParam) throws RestClientException { ... return apiClient.invokeAPI(path, HttpMethod.POST, queryParams, postBody, headerParams, formParams, accept, contentType, authNames, returnType); } And the source code for ApiClient#invokeAPI - which is also generated - is:

Problem: I am trying to use as much Spring Boot Auto-configuration as possible to reduce boiler plate code. I cannot get the Spring Validation codes to automatically map to my externalized messages.properties. It will only work if I add my own LocalValidatorFactoryBean and use the fully qualified javax constraint message. Goal I want to override the defaultMessage for @javax.validation.constraints.NotNull globally in my application based on Spring Validation code s. The first thing I did was register this bean...do I really have to? I see Spring Boot has one but it doesn't seem to correlate to

TestController.java @RestController public class TestController { @Autowired private TestClass testClass; @RequestMapping(value = "/test", method = RequestMethod.GET) public void testThread(HttpServletResponse response) throws Exception { testClass.doSomething(); } } TestClass.java @Component @Scope("prototype") public class TestClass { public TestClass() { System.out.println("new test class constructed."); } public void doSomething() { } } As you can see, I'm trying to figure out whether a new TestClass has been injected when visit "xxx/test". "new test class constructed." got printed only

In my controller I have a method for creating an entity import javax.validation.Valid; ... @RestController public class Controller { @RequestMapping(method = RequestMethod.POST) public ResponseEntity<?> create(@Valid @RequestBody RequestDTO requestDTO) { ... with import org.hibernate.validator.constraints.NotEmpty; ... public class RequestDTO @NotEmpty // (1) private String field1; //other fields, getters and setters. I want to add a controller method update(@Valid @RequestBody RequestDTO requestDTO) but in this method it should be allowed for field1 to be empty or null, i.e. the line

I'm implementing long polling as per the Spring blog from some time ago . Here my converted method with same response signature as before, but instead of responding immediately, it now uses long polling: private Map<String, DeferredResult<ResponseEntity<?>>> requests = new ConcurrentHashMap<>(); @RequestMapping(value = "/{uuid}", method = RequestMethod.GET) public DeferredResult<ResponseEntity<?>> poll(@PathVariable("uuid") final String uuid) { // Create & store a new instance ResponseEntity<?> pendingOnTimeout = ResponseEntity.accepted().build(); DeferredResult<ResponseEntity<?>>

An Abstract controller class requires List of objects from REST. While using Spring RestTemplate its not mapping it to required class instead it returns Linked HashMAp public List<T> restFindAll() { RestTemplate restTemplate = RestClient.build().restTemplate(); ParameterizedTypeReference<List<T>> parameterizedTypeReference = new ParameterizedTypeReference<List<T>>(){}; String uri= BASE_URI +"/"+ getPath(); ResponseEntity<List<T>> exchange = restTemplate.exchange(uri, HttpMethod.GET, null,parameterizedTypeReference); List<T> entities = exchange.getBody(); // here entities are List<LinkedHashMap
