问题
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

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****
回答1:
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.
回答2:
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
