I'm stuck with the following problem. My application doesn't create my Services at startup and I end up with a NullPointerException
when I try to use them in my Maven Tests after Inject them with @Autowired
.
I don't understand where it comes from. I have done some research but I still don't understand why it doesn't work.
Here is the class where my Autowired administrationActionService
is null:
public class AdministrationActionTests extends EntityTests {
@Autowired
AdministrationActionService administrationActionService;
@Test
public void equalsTests() {
administrationActionService.getExample();
[...]
The class :
package com.bloombooking.services;
@org.springframework.stereotype.Service
public class AdministrationActionService extends ServiceEntity{
@Autowired private AdministrationActionDao administrationActionDao;
[...]
And my ApplicationContext.xml
. I've placed it in src/ApplicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.bloombooking.services, com.bloombooking.dao"/>
</beans>
I really don't know what I could have done wrong. Can someone help me? Thanks!
To make it work you have to make the following changes:
@RunWith(SpringJUnit4ClassRunner.class)
to your class. @ContextConfiguration("path_to_you_spring_beans.xml")
So your class becomes:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("path_to_you_spring_beans.xml")
AdministrationActionTests {
}
