autowired

问题 since i plan to upgrade my Symfony version i want to remove all Deprecations. I cant figure out how to remove my last two errors. One is Autowiring services based on the types they implement is deprecated since Symfony 3.3 and won't be supported in version 4.0. You should rename (or alias) the "eight_points_guzzle.client.trigger_api" service to "GuzzleHttp\ClientInterface" instead. But in my serivce, i already use the client interface to inject public function __construct( LoggerInterface

问题 I am working on a web-app with Spring MVC. This is the exception I am getting: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: java.lang.IllegalArgumentException: Can not set com.onclave.papercraft.DAO.tenantDAO.Implementation.UsersDAOImplementation field com.onclave.papercraft.DAO.tenantDAO.Controller.UsersDAOController.usersDAOImplementation to com.sun.proxy.

问题 i'm learning spring now. here's my sample code. i'm using jersey, spring, hibernate, and mysql for my REST service. CustomerServiceImpl.java which is REST endpoint (partial code) package com.samples.service.impl; @Path("customers") public class CustomerServiceImpl implements CustomerService { private static Logger logger = Logger.getLogger(CustomerServiceImpl.class); @Autowired CustomerBO customerBO; here is CustomerBOImpl.java (partial code) package com.samples.BO.impl; @Component public

问题 I have a basic Spring Boot application annotated like this: @SpringBootApplication public class ApiApplication { public static void main(String[] args) { SpringApplication.run(ApiApplication.class, args); } } I have the following entries in my application.properties file: spring.datasource.driver-class-name=org.postgresql.Driver spring.datasource.url=jdbc:postgresql://localhost:5432/db spring.datasource.username=dbuser spring.datasource.password=dbpassword From my understanding Spring Boot

问题 This is the first time I can't find a solution to my problem on stackoverflow: I'm trying to create an executable-jar standalone application with annotation-based autowiring, but I can't get the runnable jar file (exported from Eclipse as runnable JAR file) to do it's job. It does run as Java application from Eclipse directly, just not as standalone app via console > java -jar test.jar . Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect

问题 I had encountered a problem described in this question, which I've already resolved by adding @Autowired annotation to constructor. Now I wonder, why it helped. What is a difference between public RegistrationController(UserDao userDao) { this.userDao = userDao; } and @Autowired public RegistrationController(UserDao userDao) { this.userDao = userDao; } In both cases, userDao is injected to Controller. Only difference I discovered is that entityManager tagged with @persistenceContext

问题 How can I get an already existing object spring managed? I would like to hook it up to Springs AoP capabilities using aspectj . I know this to be a challenge since Spring AoP uses dynamic proxies which probably are created along with the object. Why do I need this? I have a third-party class which takes a constructor argument which is only known in runtime , hence it seems I cannot add it to my applicationContext or use springs FactoryBean interface for construction. Is there any other way? I

问题 I am trying to get a bean injected into a custom ConstraintValidator . I have come across some things: CDI is supported in validation-api-1.1.0 (Beta available) Hibernate Validator 5 seems to implement validation-api-1.1.0 (Alpha available) Use Seam validation module Use Spring's LocalValidatorFactoryBean The last one seems most appropriate for my situation since we're already using Spring (3.1.3.Release). I have added the validator factory to the XML application context and annotations are
