How Do I use Jasypt with springs autowire?

Question

I have see some solutions for this without the autowire but I am trying to get it to work with with the auto wire. I have been trying this since last week but found no solutions that worked in my case, it may be that I am not implementing it correctly so any help would be great.

I have a properties file myprops.properties:

Wsdl=someurl
UserName=admin
UserPassword=ENC(encriptedpassword)

and in my servlet.xml file I replaced

<context:property-placeholder location="classpath*:myprops.properties" />

with

    <bean id="propertyPlaceholderConfigurer"
            class="org.jasypt.spring.properties.EncryptablePropertyPlaceholderConfigurer">
            <constructor-arg ref="configurationEncryptor" />
            <property name="location" value="classpath:myprops.properties" />
        </bean>
        <bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
            <property name="config" ref="environmentVariablesConfiguration" />
        </bean>
        <bean id="environmentVariablesConfiguration"
              class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
              <property name="algorithm" value="PBEWithMD5AndDES" />
              <property name="passwordEnvName" value="APP_ENCRYPTION_PASSWORD" />
</bean>

and in my service.java I am auto wiring these values like this:

    @Autowired
    public void setUserPassword(@Value("${UserPassword}") String userPassword) {
        this.userPassword = userPassword;
    }

    @Autowired
    public void setUserName(@Value("${UserName}") String userName) {
        this.userName = userName;
    }

    @Autowired
    public void setWsdl(@Value("${Wsdl}") String wsdl) {
        this.wsdl = wsdl;
    }

Thing is this works when I don't have the password encripted i.e. UserPassword=nonencriptedpassword

but as soon as I encripted it and use ENC() I get the following error

weblogic.application.ModuleException:

    at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt(StandardPBEStringEncryptor.java:705)
    Truncated. see log file for complete stacktrace

This may be down something stupidly simple that I am unaware of or have over looked but I have tried following tutorials on the Jasypt wiki and site as well as tutorials xmx1024 and on jayway and I'm sure I had found one using the autowired but I can't seem to find it again.

FYI: I am using spring 3.0.4, Spring Security 3.0.4 and jasypt 1.9

any help would be Awesome

Update

I have set an Enviorment Variable APP_ENCRYPTION_PASSWORD equal to the plain text password and set the password in the properties file as the returned value of encrypt input=plaintextpassword password=APP_ENCRYPTION_PASSWORD

I now get the Error

Password encription was done in the following way

C:\Users\jonnie\Desktop\jasypt-1.9.0\bin>encrypt input=****** password=APP_ENCRYPTION_PASSWORD

----ENVIRONMENT-----------------

Runtime: Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM 20.12-b01



----ARGUMENTS-------------------

input: *******
password: APP_ENCRYPTION_PASSWORD



----OUTPUT----------------------

****encriptedPassword****

Instead of autowiring, try just having class fields for each property and annotate those with `@Value`. — Sotirios Delimanolis, Mar 11 '13 at 14:35
@SotiriosDelimanolis But Should I be able to accomplish this using the Autowire? — jonnie, Mar 11 '13 at 14:50
I'm not sure. `@Autowired` should be used with Spring beans. Your Strings aren't declared as beans anywhere. `@Value` is used to give a default value to a field and I think that is what you're looking for. — Sotirios Delimanolis, Mar 11 '13 at 14:55
I'm not very experienced with spring and was kinda thrown into the deep end awhile back so excuse my ignorance but if I remove the `@Autowired` and leave the `@Value` where it is, is that what you mean? — jonnie, Mar 11 '13 at 14:59
Remove the `@Autowired`, get rid of setter methods and just annotate your private fields with the `@Value`. You can keep the setters, but annotate your fields instead of the annotating the argument of the methods. — Sotirios Delimanolis, Mar 11 '13 at 15:00
I get the exact same error using the `@Value` as using the `@Autowired` It only happens when I use the ENC() because both publish to the server fine when I don't use ENC() — jonnie, Mar 11 '13 at 15:08
That's not it, EnvironmentStringPBEConfig returns null if the value is not configured...hmm — Sotirios Delimanolis, Mar 11 '13 at 15:15
Change the `passwordEnvName` property value in your xml to `UserPassword`. Let's try everything. — Sotirios Delimanolis, Mar 11 '13 at 15:17
I get `Invalid property 'UserPassword' of bean class [org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig]: Bean property 'UserPassword' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?` and I tried it with the setters restored as well and get same error — jonnie, Mar 11 '13 at 15:26
ah sorry. I tried that now and I get the Original error `java.lang.NullPointerException at org.jasypt.encryption.pbe.config.SimplePBEConfig.getPasswordCharArray(SimplePBEConfig.java:434)` — jonnie, Mar 11 '13 at 15:32

This blog post has a nice example of using @Value on a bean that is build using @Service. The test uses @Autowire to set up the @Service bean.

Set the below variable Eclipse - go to run config and under environment tab set below new variable key/value APP_ENCRYPTION_PASSWORD=MyKey If running on UNIX - export APP_ENCRYPTION_PASSWORD=MyKey
Create the beans like below =>

classpath:/app1.properties classpath:/app2.properties

How Do I use Jasypt with springs autowire?
