I am trying to run a Vaadin projekt with Spring Boot on a Tomcat applicationserver on a Ubuntu 18.04 Server.
I downloaded the Vaadin Flow Spring Starter Projekt: https://vaadin.com/start/latest/project-base-spring
But when I deploy it on tomcat and try to open it, I get this error:
There was an exception while trying to navigate to '' with the exception message 'Unable to create an instance of 'de.web.michail.spring.MainView'. Make sure the class has a public no-arg constructor.'
java.lang.IllegalArgumentException: Unable to create an instance of 'de.web.michail.spring.MainView'. Make sure the class has a public no-arg constructor.

I don't understand how this base example project is not running.
Do you thing tomcat is the issue? Maybe an other applicationserver like WildFly will run correct?
Let Application extend SpringBootServletInitializer solves the issue.
public class Application extends SpringBootServletInitializer {
// ...
}

I'm encountering a issue, where autowiring doesn't work when I add Hystrix(EnableHystrix) in my microservice.
Controller class:
#RestController
#RequestMapping("/login")
#Slf4j
public class LoginController {
#Autowired
ILoginService loginService;
#ApiOperation(value = "Validate user credentials", response = LoginUser.class)
#PostMapping(value = "/validateCredentials")
private ResponseEntity<LoginUser> validateUserCredentials(#RequestBody LoginUser logginUser) {
LoginUser user=loginService.validateUser(logginUser);
......
.....
}
}
Autowiring of ILoginService works perfectively without Hystrix.
But when I add the dependency( Version 2.2.6 Release)
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
And enable Hystrix as:
#EnableFeignClients("com.abcd")
#SpringBootApplication
#EnableHystrix
public class MyApplication{
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
The Autowire of ILoginService fails and NullPointerException is thrown when trying to access the autowired property.
I have this configuration working fine in other microservices, But fails in this particular microservice. What is going wrong here?
EDIT:
StackTrace is:
java.lang.NullPointerException

In the current form, its kind of hard to tell what exactly happens.
So I'll provide some thoughts that can lead to the solution:
You say,
The Autowire of ILoginService fails and NullPointerException is thrown when trying to access the autowired property.
Usually when its possible to autowire a bean because it doesn't exist or something, spring should throw an exception during the startup and it will be impossible to "access" the autowired property during the statrup because the system won't start, so this is confusing. Maybe if you could provide a stacktrace and the place where you're trying to access the property it could become more clear...
Its possible in theory (again the stacktrace could show that) that someone tries to access the property before the autowiring actually executes. Technically its implemented in spring via BeanPostProcessor with certain priority that might compete with other bean post processors.
Try to rewrite the controller to use constructor injection (so that spring would inject the ILoginService during the construction of the controller:
#RestController
public class LoginController {
// Note, no autowiring here
private final ILoginService loginService;
// If you are on old spring you need to mark this constructor with #Autowired,
// in the recent spring versions its not required anymore as long as this is the only
// constructor of your class
public LoginController(ILoginService loginService) {
this.loginService = loginService;
}
After you're doing this, try to place a breakpoint in the constructor and see what exactly gets injected (this is an advantage of constructor injection in this case)

i read my console and found that the main reason behind this failure was ambiquity in #RequestMapping in my Home.controller so i updated my annotation and then my Homepage start loading just fine
I'm upgrading our existing spring boot 1.5 app to Spring boot 2.0. The application utilizes Spring Integration xmls as well.
The Ehcache component is causing issues while trying to to this. While trying to add the response of a GET call to cache, its throwing an exception:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.messaging.MessageHandlingException: error occurred in message handler [httpGatewayLookupSize]; nested exception is net.sf.ehcache.CacheException: When configured copyOnRead or copyOnWrite, a Store will only accept Serializable values, failedMessage=GenericMessage [payload={}, headers={http_requestMethod=GET .....]] with root cause
java.io.NotSerializableException: org.springframework.integration.support.MessageBuilder
With Spring Boot 1.5 it works perfectly fine and the value(XML Response) inserted in the Cache is of type GenericMessage.

Do i need to explicitly cast the response to make this work?
CacheInterceptor implementation that i have:
private MethodInterceptor createGatewayInterceptor(String cacheName) {
CacheInterceptor interceptor = new CacheInterceptor();
interceptor.setCacheManager(cacheManager());
NameMatchCacheOperationSource source = new NameMatchCacheOperationSource();
CacheableOperation.Builder operationBuilder = new CacheableOperation.Builder();
operationBuilder.setCacheName(cacheName);
source.addCacheMethod("handle*Message", Collections.singleton(operationBuilder.build()));
interceptor.setCacheOperationSources(source);
interceptor.setKeyGenerator((target, method, params) -> ((Message) params[0]).getHeaders().get(HEADER_CACHEKEY));
return interceptor;
}
DSL cache implementation:
adviceChain.add(eternalCacheAdvice);
adviceChain.add(genericMessageAdvice);
handler.setAdviceChain(adviceChain);
return handler;
#Bean
public MethodInterceptor cacheAdvice() {
return createGatewayInterceptor(TWENTY_FOUR_HOUR_CACHE);
}
#Bean
public MethodInterceptor eternalCacheAdvice() {
return createGatewayInterceptor(ETERNAL_CACHE);
}
#Bean
public MethodInterceptor genericMessageAdvice(){
return invocation -> ((MessageBuilder<?>) invocation.proceed()).build();
}
#Bean
public MethodInterceptor genericXMLMessageAdvice(){
return invocation -> ((MessageBuilder<?>) invocation.proceed()).build();
}
XML advice chain:
<int-http:request-handler-advice-chain>
<ref bean="genericXMLMessageAdvice" />
<ref bean="cacheAdvice" />
</int-http:request-handler-advice-chain>
For some internal optimization many out-of-the-box Spring Integration components now return a MessageBuilder before producing replies. This is needed to enrich a target reply message with extra headers.
Looks like the CacheInterceptor performs invocation.proceed() ad tries to use the result as is for caching.
Consider to add one more MethodInterceptor before your configured CacheInterceptor with a simple implementation like this:
invocation -> ((MessageBuilder<?>) invocation.proceed()).build()
So, your CacheInterceptor will get an expected GenericMessage<?> as before.
BTW, we have a PR about caching this n Spring Integration: https://github.com/spring-projects/spring-integration/pull/2105. Feel free to share there your experience, so it may push an out-of-the-box support.
I have a spring-boot security demo,I want to share session with redis.I add some code to pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
</dependency>
and new one redis config class
#Configuration
#EnableRedisHttpSession
public class RedisSessionConfig {
#Bean
public RedisTemplate<Object, Object> sessionRedisTemplate(
RedisConnectionFactory connectionFactory) {
RedisTemplate<Object, Object> template = new RedisTemplate<>();
template.setKeySerializer(new GenericJackson2JsonRedisSerializer());
template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
template.setConnectionFactory(connectionFactory);
return template;
}
}
add param to 'application.properties' file.
spring.session.store-type=redis
# redis database
spring.redis.database=8
# redis host
spring.redis.host=102.128.2.65
# redis password
#spring.redis.password=
#redis port
spring.redis.port=6379
the program can startup as before.and I can find some spring message in the redis.
enter image description here
It's wrong when login success.I find spring security put the SessionRepositoryFilter$SessionRepositoryRequestWrapper$HttpSessionWrapper to session with the session key 'SPRING_SECURITY_CONTEXT' when login success .
why? The HttpSessionWrapper class is a spring's inner class.why spring put it to redis and did't serialized?
I don't know how to fix this problem.please help me ,thanks very much.

In fact,I was download the spring source code and try fix it by edit source code.but I give up when spring haven't the problem but another apache class appear. So... is my config file wrong? or spring security share session doesn't like my way?
#Bean
public ConfigureRedisAction configureRedisAction() {
return ConfigureRedisAction.NO_OP;
}
The project that I have is currently set up like so:
Controller:
package com.frclocks.district.controller;
:imports:
#Path("/districts")
#Controller
public class DistrictController {
#Autowired
private DistrictService districtService;
#GET
#Produces(MediaType.APPLICATION_JSON)
public List<District> getDistricts() {
return districtService.getAllDistricts();
}
}
Service (Impl):
package com.frclocks.district.service;
:imports:
#Service("districtService")
#Transactional
public class DistrictServiceImpl implements DistrictService {
#Autowired
private DistrictDao districtDao;
#Override
public List<District> getAllDistricts() {
return districtDao.getAllDistricts();
}
}
Config:
package com.frclocks.config;
:imports:
#Configuration
#ComponentScan(basePackages="com.frclocks", includeFilters=#ComponentScan.Filter(Controller.class))
public class AppConfig { }
The web.xml is empty as I'll be using JavaConfig instead of xml, nor do I have any spring config xml. I have read through several tutorials online, several threads on here, and even browsed through a project at work that I'm developing with which also uses #Autowired and have reached a brick wall. Some of the tutorials say to do something in a main class (such as here: Spring Docs) but the project at work doesn't do anything like that. It has a similar AppConfig (with a few additional, not necessary annotations for me) and no xml config files. What would I be doing wrong? What am I missing here? Thanks!

You have mixed RestEasy and Spring MVC. You should decide for either of those frameworks for your REST endpoints. #Controller is a Spring annotation, while #Path is a JAX-RS annotation. Both together don't work. Currently your Controller is called through RestEasy, which doesn't know anything about your Spring configuration.
