问题 I am new to spring. I am developing a REST api with spring webmvc. For Error Handling I got this link http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-ann-rest-spring-mvc-exceptions I have tried to use ResponseEntityExceptionHandler in my project . but whenever my controller throws exception it never reaches to this ResponseEntityExceptionHandler. Following are my code snippet Controller @Controller @RequestMapping("/hello") public class HelloController {

问题 I am trying to clear a session. Below is a little sample code I wrote to check with SessionStatus . @Controller @SessionAttributes(value={"sessAttr1","sessAttr2","sessAttr3"}) public class SessionController { @RequestMapping(value="index") public ModelAndView populateSession(){ ModelAndView modelView = new ModelAndView("home"); modelView.addObject("sessAttr1","This value is added in a session 1"); modelView.addObject("sessAttr2","This value is added in a session 2"); modelView.addObject(

问题 I know why assertive programming is good, so I want to use it with JavaScript. However, I don't want to show users error boxes, and it's unusual thing. Just ignore it and make them retry could be better. For example this code will make an error box and interrupt users. function getDomainFromURL(url) { assertTrue(url, 'URL should not be null'); ...parsing } So, I'd make like this. function getDomainFromURL(url) { if (!url) return; ...parsing } Second one is good for usability, I think, and

问题 I am working with Spring 3.1.0. I am trying to understand the way spring is reading its xml files. I am trying to understand how spring deals with ambiguous conditions in the bean definitions. For example I have Alarm.java package com.anshbansal.alarm2; public class Alarm { private String type; private int volume; private int hour; public Alarm() { } public Alarm(String type, int volume, int hour) { this.type = type; this.volume = volume; this.hour = hour; } public Alarm(String type, int

问题 I am using Spring 3 MVC. I have both mvc-dispatcher-servlet.xml and applicationContext.xml. But applicationContext.xml is not loading only mvc-dispatcher-servlet.xml is loading. Any problem with my configuration? web.xml <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>Archetype Created Web Application<

问题 I'm having hard time to setup springframework code in Intellij. I git-cloned springframework project from github, and ran ant task to get all the libraries into ivy-cache directory. I found "spring-framework.ipr" file for intellij project, and opened it. Unfortunately, some of the libraries are not correctly mapped to the jar files or missing. So I cannot compile the codebase in IDE. I also tried importing as eclipse project into intellij. Jar file reference seems ok. But there are

问题 Similarly to this question regarding an earlier Spring version, what are the minimum dependencies required for an application to use Spring 3.0 dependency injection only? The application context will be configured by XML only. Spring depends on a logging framework, so assume I already include these JARs for logging: jcl-over-slf4j.jar logback-classic.jar logback-core.jar slf4j-api.jar 回答1: As stated in another answer, maven is the true path. If; however, you choose to stray, then based on
