I'm trying to test a service with Mockito and testNG, but i have a couple of doubts. It's necessary create get/set to inject service, if service is declaredd like this:
#Autowired(required = true)
protected ITipService serveiTip;
when I'm trying to clean and package with maven I found this exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'consultaDeutes' defined in URL
[file:/D:/workspaceGPT/GPT/gpt.ui/target/test-classes/applicationContext-gui-deutes-Test.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'serveiTip' of bean class [cat.base.gpt.ui.ConsultaDeutesTest]: Bean property 'serveiTip' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
I believe that with autowiring get/set will be not necessary.
this is my test-context:

Using #Autowired will make spring automatically inject a matching bean into that field. Thus it is no longer required to define the "consultaDeutes" bean in the xml. If you'd like to use the xml definition, I believe you should define a setter for each property that you are trying to inject, eg: serveiTip, serveiGpt.
Using #Autowired in your test might require 2 additional annotation on the definition of your test class:
#ContextConfiguration(value = "/myContext.xml")
//#RunWith(SpringJUnit4ClassRunner.class) This is JUnit specific
#ActiveProfiles("dev")
public class TestCompareService {
#Autowired(required = true)
protected ITipService serveiTip;
....
}
I actually made a mistake pasting the #RunWith annotation specific for JUnit. For TestNG you can lookup this link. Apologies

When I access a bean from spring bean configuration file using BeanFactory like this:
public class Person {
private String id,address;
#Autowired
private Customer customer;
//setters & getters
}
and bean configuration file
<bean name="person" class="com.ram.spring.model.Person"></bean>
<bean class="com.ram.spring.model.Customer">
<property name="email" value="ram#adp.com"></property>
<property name="name" value="Ram"></property>
</bean>
here is the executor class
public class PersonExecutor {
public static void main(String[] args) {
BeanFactory context = new XmlBeanFactory(new ClassPathResource("Spring.xml"));
Person person = (Person)context.getBean("person");
System.out.println(person.getCustomer());
}
}
when I execute this, I got null.is BeanFactory not supported for annotations?? any ideas??
Approach 1: Include below code in your xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<!-- Remaining bean declaration -->
</beans>
Approach 2: Remove #Autowired and inject customer in your xml file only.
<bean name="person" class="com.ram.spring.model.Person">
<property name="customer" ref="customer"></property>
</bean>
<bean name="customer" class="com.ram.spring.model.Customer">
<property name="email" value="ram#adp.com"></property>
<property name="name" value="Ram"></property>
</bean>
You have to use AnnotationConfigApplicationContext or
you have to add to yor Spring.xml to activate the annotation scan.
As #jens suggested
you should active annotation scan
<context:component-scan base-package="package_path">
</context:component-scan>
<context:annotation-config />
hope that helped
Why doesn't it work?
When using Spring with an XML context, using annotations is not activated by default. This means #Autowired, #Transactional, #PostConstruct and any other annotation you will use will simply not be exploited.
How do I fix it?
To make Spring aware of annotations, you need to add the following line:
<context:annotation-config />
Thus, Spring will search for annotations in the beans it creates and process them accordingly.
This requires activating the context namespace. At the top of your context, make sure you have all context related links and arguments1:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config />
<!-- Your context -->
</beans>
You do not need <context:component-scan /> in your case. This would be useful if you used full-annotation context (e.g. classes annotated with #Component). See the difference between <context:annotation-config /> and <context:component-scan /> in this answer.
Alternate solution
As Naman Gala suggested, you could also drop #Autowired completely and inject all dependencies in XML. See the related answer for more details.
1 This includes the xmlns:context attribute (xmlns = XML NameSpace) and two URLs in xsi:schemaLocation.
following the answer given in this question, I have removed the spring-webmvc.jar file from my lib to avoid a repetition with the one in the core project. However, when I do this, it seems that the #Autowired for at least a bean does not work any more.
The class having the #Autowired is the following (in which none of the field is filled):
public class SecurityUserCheckBeforeControllerHandler implements BeforeControllerHandler
{
#Resource(name = "userService")
private UserService userService;
#Autowired
private CMSPageContextService cmsPageContextService;
#Override
public boolean beforeController(final HttpServletRequest request, final HttpServletResponse response,
final HandlerMethod handler) throws IOException
{
// Code where the autowired fields are used (-> produces null pointer)
}
}
The spring configuration can be summarized as follows:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>
If I follow the advise given in most of the similar questions (i.e. adding an #Component above the class that would be scanned), the bean will be created twice:
with the list given in the config file:
The autowired fields will be null which will still give a NullPointerException when the bean in the list is used
by the component-scan:
The fields are correctly autowired but the bean is not used in the list.
Strangely, if I put back the spring-webmvc.jar previously removed because of this question, the #Autowired will work as expected.
Trying to compare the stacktraces between the two configurations, I saw that the beans are created at different moments in the class org.springframework.context.support.AbstractApplicationContext during the startup of the server.
Last point: there is no error during the compilation and the startup of the server.
Do you have any idea for a solution please?
Thank you for reading me,

I'm still new to spring and I'm trying to get ehcache spring annotations setup correctly. I'm using Spring 3.2.3 ehCache 2.4 and ehcache-spring-annotations-1.2.
When I try to access the reference to the cacheManager, it is always null. All the jars are on the build path, ehcache.xml is in the classpath and there are no xml errors. I've tried also including the classes in the component scan and using #Resource instead of Autowired. I'm stuck!

It seems you are trying to use the EhCacheManagerFactoryBean as your cache manager.
Looking at Spring caching documentation, you need to declare another bean to be your CacheManager created from the factory.
I have a Spring 3.1 application, and I try to use a system variable in the context files. The variable "JAVA_MY_ENV" is defined on my System (on Windows, it is in the "System variables", from the control panel).
In web.xml, I can use it as a variable and it works, it is successfully replaced by the actual value of the variable (let's say "electrotype") :
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log/${JAVA_MY_ENV}.log4j.properties</param-value>
</context-param>
I can also use it in my main "bean" context, to do an import, and it also works :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

But In "app-config.xml", one of my other context file, I try this and it doesn't work :
<?xml version="1.0" encoding="UTF-8"?>

<bean id="appConfiguration" class="com.xxx.app.AppConfiguration">
<constructor-arg value="${JAVA_MY_ENV}" />
</bean>
</beans>
The com.xxx.app.AppConfiguration receives the String "${JAVA_MY_ENV}" as the constructor parameter, not the interpreted value of it!
I'm not sure to understand where the ${} variables are interpreted and where they are not.
Is there a way I can pass the interpreted ${JAVA_MY_ENV} value to my com.xxx.app.AppConfiguration constructor?
As of 3.0 in Spring you should be to inject values into properties
#Value("#{ systemProperties['JAVA_MY_ENV'] }")
private String myVar;
or
<property name ="myVar" value="#{systemProperties['JAVA_MY_ENV']}"/>
Alternatively you can look into using the PropertySourcesPlaceholderConfigurer or similar class. Creating this will tell spring how to look for variables. Often i make a number of property files as well so that environment and internal property file values are available to the app. e.g.
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:someprops.properties</value>
</list>
</property>
<property name="ignoreResourceNotFound" value="true" />
<property name="searchSystemEnvironment" value="true" />
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
A key element in the above example is the "searchSystemEnvironment" being set to true. This tells spring to use env variables (which is what you want)
Possible duplicate of <context:property-placeholder> properties not accessible to the child (web) context
As I understand this is expected behavior. You should inject beans only in servlet context or to include configuration bean into servlet-context.xml
To use a PropertyPlaceholderConfigurer, suggested by BruceLowe, works. Another way (maybe more complicated) I found to resolve a specific property is using :
<bean id="JAVA_MY_ENV" class="org.springframework.util.SystemPropertyUtils" factory-method="resolvePlaceholders">
<constructor-arg value="${JAVA_MY_ENV}" />
</bean>
This creates a String bean containing the resolved value of ${JAVA_MY_ENV}!
Then I can use this bean anywhere a bean ref can be used. For example as a constructor-arg:
<bean id="appConfiguration" class="com.xxx.app.AppConfiguration">
<constructor-arg ref="JAVA_MY_ENV" />
</bean>
So now I use ${JAVA_MY_ENV} in places where it is interpreted, without adding PropertyPlaceholderConfigurer, and the JAVA_MY_ENV bean otherwise.
Is there a special way for doing this?
What i got is:
config.properties with param.key=value
web.xml with ContextLoaderListener that reads the configuration
pages-servlet.xml that defines servlet beans.
What I want is to configure one of the beans in pages-servlet.xml with param.key.
I'm using <property name="myField" value="${param.key}"/> in the xml but I see that the field is configured with ${param.key} instead of 'value'.
What is the right way to configure the bean?
Ok, I solved it by importing application context file that defines configuration bean into pages-servlet.xml.
It works, but seems very wrong.
Property placeholder is what you want.
