Turn on Autowire in Spring - java

I check my application without
<context:spring-configured/>
and the #Autowire working properly. I don't know how the container can auto inject without
<context:spring-configured/>
Here is my application-context.xml:
<?xml version="1.0" encoding="UTF-8"?>

Autowiring is working because of
context:component-scan
Check out this javadoc

You need to add context schema into your Configuration XML to use #Autowired annotation, like below :
<?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-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:annotation-config/>
For more check the link below :
3.11. Annotation-based configuration
Also, check the difference between context:annotation-config vs context:component-scan , You were getting #Autowiring because of the context:component-scan being used in your context schema.

Can I define SpringDataJpa repository without <context:annotation-config/>

I would like to know why I am getting this error Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: EntityPathResolver must not be null! when I am not having <context:annotation-config/>. From my understanding the <context:annotation-config/> should only enable annotations like #Autowire, #Resource etc.

Spring encrypt and decrypt API key in properties file

Original Question
I have a properties file located in Tomcat and a properties file for testing located in src/test/resources.
At the moment I have the following setup. My properties files are loaded in my XML files
config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- Repository and Service layers -->

And I am able to access these values by doing placing this in my Java files
public class SunnycarsClient extends WebServiceGatewaySupport {
#Value("${sunnycars.serviceUri}")
private String uri; // provided by the webservice
#Value("${sunnycars.operatingKey}")
private String key; // provide by the webservice
#Value("${sunnycars.passphrase}")
private String passphrase; // provided by the webservice
}
At the moment the operatingKey and passphrase are stored in these properties as plane text. I want to store them as an encrypted value to minimize the risk and still be able to access in the way I do now.
Update 1
So what i did now is replace the content of config.xml to
<?xml version="1.0" encoding="UTF-8"?>

But it's still not clear to me how I should access these from my Java code.
Also in the propeties files I should replace sunnycars.operatingKey = THE_KEY with sunnycars.operatingKey = enc(ENCRYPTED_KEY), but how do you get the ENCRYPTED_KEY value?
First you have to download jasypt1.9* toolkit from http://www.jasypt.org/
and
Try to run encrypt.dat file with following command in cmd like
encrypt.date input=[YOUR PROPERTY FILE VALUE] password=[encryption key value]
it will generate
output of encrypted value which you need to replace at properties file
with
=ENC(output encrypted value)
..
<bean class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndDES" />
<property name="password" value="APP_ENCRYPTION_PASSWORD" />
</bean> ..
you can also hardcode password at class file and assign to bean as well
<bean class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndDES" />
<property name="password" value="#Key.keyValue}" />
</bean>
where Key.keyValue is Static method of Key class.
Take a look on Jasypt. It supports encrypted properties (http://www.jasypt.org/spring31.html).

How do I configure the date format the server returns using CXF JAX-RS and Jackson 2 in XML?

This took me a lot of effort to figure out so I'm going to answer the question below. This answer doesn't use annotations and does not require creating additional classes.
You put this in your spring xml context configuration:

Referenced bean 'name' not found

For some strange reason, this dataSource bean is found in 3 of my dao-beans, but not in the other ones (For example Spring-name1). Whats the difference?

I have the required DAO files in respective package corretly, why is the second one working but not the first one? There is no difference..
Thanks in forehand!
I fixed this by adding Config Sets (Bean support) for my project. Don't know if this is the exact right solution, but it removed the errors at least:
Right click on project->properties->Spring->Bean Support-> Config Sets
(Do a Scan before in the previous page), then I just added them all
together in a random config set. =)

Have a look at http://blog.neo4j.org/2014/03/spring-data-neo4j-progress-update-sdn-3.html
This is actually a duplicate question from earlier on Stack, but, long and short is that if you're using the latest SDN (and I'm pretty sure you are), then you need to include the "base-package" attribute in both the neo4j:config and neo4j:repositories elements.
In the link above, Michael Hunger explains this and you can clearly see what the values for those attributes should be.
