Spring

问题 I have a small Java/Spring MVC REST /Maven app that runs just fine in Eclipse but also when I run the following command from the prompt: mvn clean tomcat6:run My problem is when I do: mvn clean package and push the generated war file to the "webapps" folder in my standalone Tomcat instance, the service doesn't work anymore. The standalone Tomcat starts up just fine, no error in the logs. Interestingly enough though the standalone instance listens on port 8989 vs. 8080 when I run the app in

问题 I'm working on an API endpoint that returns a Springframework Page response. I want the front end to be able to sort the data but I can't expect the front end to know that the column they want to sort on is actually inside a composite primary key. In the example below (a simplified version of what I'm working on) you can see that the startDate column is inside a RouteEntityPk class, which is linked to the RouteEntity class with the @EmbeddedId annotation. To Sort on that column the front end

问题 I'm wondering about proper way of implementating of controller in case of GET request with multiple request params given. In my understanding of REST it's much better to have one endpoint with additional parameters for filtering/sorting than several endpoints (one for each case).

Please have a look on example below : @RestController @RequestMapping("/customers") public class CustomerController { @Autowired private

问题 I was always wondering why no primefaces theme gets applied and could never fix it. Today I found out that when I add a Bean "ServletContextInitializer" to my Application with the same stuff like in the web.xml it works. I read something that app.properties maybe overrides the settings? I got a application.properties but just for the database and jpa/hibernate. Application: @EnableAutoConfiguration @ComponentScan({ "de.develop.telefonbuch" }) public class Application extends

问题 The image is in the following directory: /src/main/resources/static/images/logo.png And this is my HTML tag: <img width="220px" height="70px" th:src="@{/static/images/logo.png}"/> However, when i'm trying to access the image, this error shows up: There was an unexpected error (type=Not Found, status=404). No message available 回答1: You don't need static in the path. You should use @{/images/logo.png} , because default resolver maps /src/main/resources/static/ to / url in your case. From
