Question

I’d like to use Spring with Java configuration, but almost all examples are writte in XML and I don’t know how to translate them to Java. Look at these examples from Spring Security 3:

 <http auto-config='true'>
   <intercept-url pattern="/**" access="ROLE_USER" />
 </http> 

 <authentication-manager>
    <authentication-provider>
      <user-service>
        <user name="jimi" password="jimispassword" authorities="ROLE_USER, ROLE_ADMIN" />
        <user name="bob" password="bobspassword" authorities="ROLE_USER" />
      </user-service>
    </authentication-provider>
  </authentication-manager>

  <password-encoder hash="sha">
    <salt-source user-property="username"/>
  </password-encoder>

How could this translated to Java config? Or, more generally, how can I translate Spring XML config to Java? There is a little section about Java confing in the Spring reference but it is not that helpful.

Answer 1

You can’t translate XML configurations with custom namespaces (such as http://www.springframework.org/schema/security). However, you can mix XML configurations with Java-based using @ImportResource
