问题 I have a lot of Spring RestControllers with methods annotated with RequestMapping . I now would like to inject a custom object into these RequestMapping methods, and create an custom instance for each request. I would like to write something like the following: @RequestMapping("/search") public SomeReturnObject foobar(@RequestParam("query") String query, MyRequestFoo foo) { // ... } Now I would like to create a mechanism, where each call to that method (i.e. each request) get a new instance

问题 I am trying to use an autowired reference from main class and am facing : Cannot make a static reference to the non-static field zipCodeLookupService. This is obvious. But I want to know how to handle this situation. What is the correct way of autowiring when main class is involved. My code will be as below - Interface class package com.example.services; public interface IZipCodeLookup { String retriveCityForZip(String zipCode); } Service Class package com.example.services; import org

问题 I have problems with two services that i autowired in a validator class. The services works ok because in my controller are autowired. I've an applicationContext.xml file and MyApp-servlet.xml file. My base package is es.unican.meteo and i have problems with the package es.unican.meteo.validator. The package es.unican.meteo.controller and es.unican.meteo.service can autowire the services properly. applicationContext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www

问题 I am having a little "problem" using JavaMailSenderImpl to send emails in my spring boot application. I am trying to set all properties dynamically (I will want them to be read from the DB in the future) but, for reasons unknown to me, autowiring JavaMailSenderImpl only works if "spring.mail.host" is present in my application.properties. It doesn't matter the value I set (it can be empty, it doesn't matter because I set the right one later), but the property must be there or autowiring will

问题 I want to populate requestScopedBean.userDetails when my controller's update(...) gets executed / before it is executed. In my spring web project I have java based MyConfiguration extends WebMvcConfigurerAdapter in which I have: @Bean(name = "requestScopedBean") @Scope(value = "prototype") public RequestScopedBean requestScopedBean() { return new RequestScopedBean(); } While in RequestScopedBean.java : public class RequestScopedBean { public @Autowired UserDetails userDetails; public void

问题 I've got kind of producer-consumer pattern implemented in my application. On one end producer pushes entities to process recieved from different sources, on the other hand I've got consumer which take this events out of the queue and process them. Both producer and consumer are spring beans and discovered automatically and both require link to this shared Queue. I know that I can define my beans in either xml file or Java configuration and pass this Queue as parameter as constructor argument

问题 I try to write junit test to my service. I use in my project spring-boot 1.5.1. Everything works fine, but when I try to autowire bean (created in AppConfig.class), it gives me NullPointerException. I've tried almost everything. This is my configuration class: @Configuration public class AppConfig { @Bean public DozerBeanMapper mapper(){ DozerBeanMapper mapper = new DozerBeanMapper(); mapper.setCustomFieldMapper(new CustomMapper()); return mapper; } } and my test class: @SpringBootTest public
