autowired

问题 I'm getting an exception when I start my application, where Spring complain about UnsatisfiedDependencyException: Exception in thread "main" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'applicationConfig': Unsatisfied dependency expressed through field 'controlRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean found for dependency [com.oak.api.finance.repository

问题 I have a Java Project with Spring MVC . I need to start TimerTasks already after my application is initialized, so I implemented the WebApplicationInitializer Interface and I call it SystemInitializer . Inside that class I have a @Autowired property, that @Autowired property is a DAO class. I need it cause I want to execute some tasks based in recordings from my data base. But that Autowired property is ever null. public class SystemInitializer implements WebApplicationInitializer {

问题 I want to autowire a collection of beans using Spring in annotaion mode. I've tried this something like the below ... @Configuration @ComponentScan(basePackages = "mypkg", includeFilters = @Filter(type = FilterType.REGEX, pattern = {"regex1", "regex2"}), excludeFilters = @Filter(type = FilterType.REGEX, pattern = "regex3")) public class BeanCollector { @Autowired private List<MyBean> myBeans; @Bean(name = "beans") public List<MyBean> getMyBeans() { return myBeans; } } This code works pretty

问题 Really need help. I used JUnit(4.6) plus Spring(3.0.5) for unit testing. When I tried to autowire a service object in my test class, I got a NoSuchBeanDefinitionException. The JUnit code: package com.aaa.service.impl; @ContextConfiguration(locations = { "classpath:/spring/applicationContext.xml", "classpath:/spring/applicationContext-aop.xml", "classpath:/spring/applicationContext-dao.xml", "classpath:/spring/applicationContext-service.xml" }) @RunWith(SpringJUnit4ClassRunner.class) public

问题 I'm starting a Primefaces/Spring/Hibernate project and I'm still learning how to handle those components properly. But at this right moment, I'm facing a problem related to spring dependency injection that is freaking me out. I've been look for an answer for two days over the web and couldn't find what is wrong with my code. I've tried both approaches to autowire (@Autowire ans @Inject). Could someone take a look at my code and check what's going wrong ? My code is below. Here is the error

问题 I'm having some issues with injection in the application I'm working on (using Spring Version 3.1.2). To start with, I'm seeing a lot of code like this: @Value("#{searchRequestBean}") private SearchRequest searchRequest; @Value("#{searchResponseBean}") private SearchResponse searchResponse; @Autowired private SavedSearchService service; Each of these three appears to have the effect of autowiring the specified bean/service into the class. What I don't understand is, what's the difference

问题 I am trying to implement auto-wiring into my project, but it seems that my application isn't seeing my SessionFactory definition in my application-context.xml when I am running it. I'm probably missing something really obvious, though I've tried several solutions from posts having similar issues with no success. I am using Spring MVC and Hibernate. Here is my application-context.xml. <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi=

问题 I found a strange spring behavior in instantiating the beans during initial context Loading. I had a bean that loads large ML models. Due to insufficient memory the bean failed to instantiate throwing Out java OutOfMemoryError java heap space exception. But this doesn't stop the application from instantiating, instead it continues to load the application. Why does this happen? Is this expected? checked the spring AbstractAutowireCapableBeanFactory , try { // Mark this bean as currently in

问题 I have a spring boot application where I am creating Datasource and JdbcTemplate manually in my config because I need to decrypt datasource password. I am using tomcat DataSource ( org.apache.tomcat.jdbc.pool.DataSource ) as recommended in spring boot docs since I am configuring connection properties. I am excluding autoconfiguration for datasource (see Application.java ) since I am creating one manually. Application.java // exclude datasourceAutoConfiguration since we are creating manaully

问题 As most of Spring Boot new users I have a problem with @Autowired :D I've readed a big amount of topics about this annotation here But still can't find proper solution for my problem. Let's suppose that we have this Spring Boot hierarchy: @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } } Class, that we wanna instantiate every time it's called: @Service public class TestWire { public TestWire()
