Spring Integration Could not autowire field

Spring Integration Could not autowire field - java

I have read the TCP-Server-Client and try to run my example but I am getting the following error:

I have not figured out, if is needed any other additional configuration file.
Edit 1:
My configuration file:

#EnableWebMvc
#ComponentScan(basePackages = "com.example.myapp")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
...
}

You need to import the XML configuration.
Add #ImportResource("foo.xml") to your #Configuration class.
Or, add the Spring Integration configuration using #Beans instead of XML.

It seems like you haven't specified the component scan location. Try adding the below tag to XML.
<context:component-scan base-package="<package-to-scan-under-spring-servlet>" />

Autowiring tcp-outbound-channel-adapter using Id does not work

I am trying to autowire my tcp-inbound-channel-adapter bean defined as below. Later I will be starting this on certain conditions.
<int-ip:tcp-inbound-channel-adapter
id="inboundClient" channel="replies" connection-factory="client"
client-mode="true" auto-startup="false" retry-interval="10000" />
Autowiring as:
#Autowired
#Qualifier("inboundClient")
TcpReceivingChannelAdapter inboundClient;
My inboundClient is always null.
However when I do something as below, it works, without NPE, tc has object reference and starts the inbound adapter and receives data.
TcpReceivingChannelAdapter tc = (TcpReceivingChannelAdapter)
context.getBean("inboundClient");
Thread.sleep(5000);
tc.start();
Please let me know, if you have come across this or solved this.

If I take off below from existing code
#Autowired
#Qualifier("outBoundClient")
TcpSendingMessageHandler outBoundClient;
and
outBoundClient.start();
it starts my inBoundClient
Am I trying to autowire outBoundClient in a wrong way. Please let me know if you need more details.

You should inject these beans with type SmartLifeCycle not the TcpSendingMessageHandler type. The receiving adapter will work that way, though but since you want to use the lifecycle stuff it's better to narrow the type.
The sending handler actually has a bean name outBoundClient.handler but that's not what you want to start/stop, it is wrapped in a consumer (which implements SmartLifecyle and the type depends on the channel type; in this case, an EventDrivenConsumer).

Property Inject in Spring Framework

I have problem injecting a value to a bean using Spring MVC.
Here's my partial configuration of Spring:
<beans>
<!-- Enable Annotation based configuration -->
<context:annotation-config />
<!-- MailGun.org Authentication -->
<bean class="com.example.something.util.MailSender">
<property name="smtpHost" value="smtp.mailgun.org" />
<property name="smtpUsername" value="USERNAME_HERE" />
<property name="smtpPassWord" value="PASSWORD_HERE" />
</bean>
</beans>
And here's the bean to inject:
package com.example.something.util;
#Component
public class MailSender {
public void sendMail(String recipient, String subject, String text) {
System.out.println(smtpHost);
}
#Autowired
private String smtpHost;
}
To test this, I create a test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration({"classpath:test-spring-context.xml"})
public class MailSenderTest {
#Test
public void testSendMail() {
MailSender sender = new MailSender();
sender.sendMail("zjhzxhz#gmail.com", "Mail From MailGun", "This is a test mail");
}
}
When I run this test case, I got an exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String com.example.something.util.MailSender.smtpHost; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [java.lang.String] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

What's wrong with it? Please help me. Thx!

You don't need #Autowired on smtpHost, it should be already populated if you get the MailSender bean from the Spring context. Which you don't, because instantiating it with new MailSender() bypasses Spring altogether. Instead you should use context.getBean(MailSender.class).

Need help

Probably your ApplicationContext's BeanFactory is configured with default AutowireCandidateResolver (i.e. SimpleAutowireCandidateResolver) instead of QualifierAnnotationAutowireCandidateResolver.
In previous versions of Spring (before 4.0), QualifierAnnotationAutowireCandidateResolver was set during creation of most ApplicationContexts (compare AbstractRefreshableApplicationContext.customizeBeanFactory(DefaultListableBeanFactory) implementations).
Currently, QualifierAnnotationAutowireCandidateResolver for AppCtx is/can be applied by:
org.springframework.beans.factory.annotation.CustomAutowireConfigurer (see javadoc and implementation of postProcessBeanFactory(ConfigurableListableBeanFactory) method), e.g. add to your xml:
<bean id="customAutowireConfigurer" class="org.springframework.beans.factory.annotation.CustomAutowireConfigurer">
<property name="customQualifierTypes">
<set>
<value>org.springframework.beans.factory.annotation.Qualifier</value>
</set>
</property>
<context:annotation-config /> (see: AnnotationConfigBeanDefinitionParser.parse(Element,ParserContext) and related)

#Qualifier is used to reference a bean by its name or id. Since it can't find an xml entry that has a name or id of 'small' it tries to match by type, of which it found two instances of Size.
The following would work:
<bean id="small" class="com.tests.test2.Size">
<property name="height" value="2"/>
<property name="width" value="1"/>
</bean>
Though it appears you would like to treat instances of Size as pre-configured beans. If that were the case you could declare instances of Dog in your xml file and refer to Size beans ... something like this:
<bean id="rex" class="com.tests.test2.SimpleDog">
<property name="name" value="Puppy" />
<property name="size" ref="size1"/>
</bean>

#Qualifier(name="..") annotation and give the name of the bean that we want Spring to inject
and name of your beans are size1 and size2 .
so try
#Qualifier("size1")

#Qualifier("small") means you look for a bean named "small" (bean id="small" ...) #Autowired means you look for a bean with a type that matchs.
It makes sense to use this two configurations together in some cases. It means: look for a bean named like that, and if you don't find, then look for a bean with the correct type. This can be powerful, very.
From the Spring documentation, you can declare who is "small" with an xml qualifier, as you did. But in their example there is NO id="..." I don't know if it makes sense to define both qualifier and id. So I suppose (I don't test) you can repair your example by removing the parts id="sizeX"

As says your stacktrace
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.tests.test2.Size] is defined: expected single matching bean but found 2: size1,size2
Spring can't match a single bean to inject because he find 2 beans that could using, for this reason will thrown this exception.
Exception thrown when a BeanFactory is asked for a bean instance for
which multiple matching candidates have been found when only one
matching bean was expected.
Reference of Exception
Anyway you're using this thing in the wrong way, because there isn't any bean with id="small"
You must change #Qualifier("small") to #Qualifier("size1") or #Qualifier("size2").

In Spring 4.x you should work with the following XML schema in order for this to work for you:
xmlns="http://www.springframework.org/schema/beans"

So the following XML should solve your problem (it solved mine :) ):

We have struts 1.x used with Spring 3.x in our project. In the process of upgrading from spring 3->4, our qualifier annotation in the struts action does not work any more. After digging in and compare the Spring 3 and 4, finally found the reason.
reason1: QualifierAnnotationAutowireCandidateResolver is not the default resolver in spring 4
In Spring 3, after we create our beanfacotry in the application context, Spring will explicitly call :
beanFactory.setAutowireCandidateResolver(new QualifierAnnotationAutowireCandidateResolver());
In spring 4, it is not called any more in the AbstractRefreshableApplicationContext’s
protected void customizeBeanFactory(DefaultListableBeanFactory beanFactory)
So for the parent(root) context, it should still work as is if you have the in the config xml. However for the child context the default resolver will become ‘SimpleAutowireCandidateResolver’
reason2: The child resolver is passed to parent when trying to determine ‘isAutowireCandidate()’ in Spring 4’s DefaultListableBeanFactory
The isAutowireCandidate() will delegate the responsibility to parent beanFactory if it cannot make decision.
In Spring 3, the delegation does not pass the resolver to the parent so that parent context uses its own resolver to call the isAutowireCandidate(). However in Spring 4, it changes. The resolver is passed as a parameter to the parent who uses it to call the isAutowireCandidate(). So even the parent has a ContextAnnotationAutowireCandidateResolver which extends QualifierAnnotationAutowireCandidateResolver as its resolver, it still does not help.
The #a5phyx solution should work if it is added to the child's application context xml.

Try using this bean definition in your beans.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"

Spring Integration: gateway bean not found

I try to using spring integration in different jars.
In the A.jar si-context.xml:
<context:annotation-config />
<int:annotation-config />
<int:channel id="upperServiceChannel">
<int:priority-queue />
</int:channel>
<int:gateway id="upperGateway" default-request-timeout="5000"
default-reply-timeout="5000" default-request-channel="upperServiceChannel"
service-interface="com.company.proj.gw.IUpperStringConversation">
<int:method name="toUpperCase" />
</int:gateway>
<bean id="toUpperCaseService" class="com.company.proj.service.ToUpperCaseService" />
<int:service-activator id="serviceActivatorToUpperCase"
input-channel="upperServiceChannel" method="toUpperCase" ref="toUpperCaseService" />
<int:poller id="poller" default="true" fixed-delay="1000" />
<context:component-scan base-package="com.company"/>
In a bean I'm using this gateway:
#Component(value = "upper")
public class UpperAdapter extends AAdapter<Message<String>> {
#Autowired
IUpperStringConversation gw;
It's working. The problem is, if I try to using my UpperAdapter from an other project (B.jar).
b-context.xml:
<import resource="classpath*:/*si-context.xml" />
<context:annotation-config />
<int:annotation-config />
#Component(value="router")
public class Router {
#Autowired
private Map<String, AAdapter<?>> adapters;
And here I get:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'upper': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.company.proj.gw.IUpperStringConversation com.company.proj.adapter.UpperAdapter.gw; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.company.proj.gw.IUpperStringConversation] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
After I set the spring log level to debug, get this information:
DEBUG o.s.c.a.ClassPathBeanDefinitionScanner - Ignored because not a concrete top-level class: URL [jar:file:/home/tomto/Documents/workspace-sts/integration-fw/src/main/resources/META-INF/lib/integration-fw-module-string-0.0.1-SNAPSHOT.jar!/com/company/proj/gw/IUpperStringConversation.class]
Of course, it's true, becouse (maybe I'm wrong ;)) it would be at runtime generated gateway by spring.
The IUpperStringConversation:
public interface IUpperStringConversation {
public String toUpperCase(String text);
}
What I missed?
Thx!

We had a similar issue, our gateways were not getting injected into our service object:
Project structure:
----------------
-parent/
-common/
--gateways defined here
-module-a/
-module-b/
The exception message received in module-b was:
org.springframework.beans.factory.BeanCreationException: ... Injection of autowired dependencies failed
...
IllegalArgumentException: Class must not be null
Apparently the issue was being caused by conflicting dependencies we had on the module-b classpath. After we cleaned up the Spring dependencies in pom.xml it worked!

Get a SessionFactory from LocalSessionFactoryBean without HibernateTemplate

I'm using Spring 3.1.1.RELEASE and 4.0.1.Final and read that I must avoid the use of HibernateTemplate. I didn't found a complete example in the web, so I wrote this code, but doesn't work.
Dao class
#Repository("userDao")
public class UserDaoImpl implements UserDao {
#Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
Spring Config
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
...
</bean>
But an exception is thrown : I think it's normal because sessionFactory it's not a LocalSessionFactoryBean, but i don't know how to fix it.

thanks in advance.

Had the same problem, unable to make injection work.
My problem was "sequence". Hibernate xml must be invoked first.
