Spring Roo!!!!! But a Different Demeanour

When I had my first interaction with Spring Roo, I was trying to figure the features that makes it an absolute pleasure to use. After traversing through the code that it generates, I found the following interesting features and I believe that there is more to be explored of it.

    1) InterType Declarations with Aspects.
    2) Use of @Configurable annotation.
    3) Use of JSP's in XML format i.e. (.jspx)
    4) Use of Spring Theme and Localization.
    5) Use of Apache Tiles 3 in Views.
First, of all I will start with @Configurable annotation. I am going to discuss my experience with each of the above mentioned features separately. I have tried to use them separately in a Spring based Application.

Use of @Configurable annotation.

Not, all types(beans) used in a Spring Based Application are Spring managed. Sometimes, we need to inject some dependency into some Types which are not Spring Managed. The most common example being, injection of Service or DAO layer within the Entity class. Now the instances of Entity classes are being created using the new operator, i.e. they are not Spring Managed. Now we want to inject the corresponding Service or DAO Type which is Spring Managed within these Entity Types, and these can be performed with the help of @Configurable . It is the Aspects, which performs all the underlying engineering and ,makes this thing possible. Let's see an example. @Configurable public class Person { @Autowired ResourceBundleThemeSource themeSource; private String firstName; private String lastName; private int age; private Address address; @CustomDateFormat Date birthDate; MultipartFile profile; public String getFirstName() { return firstName; } public voi

Spring WS - Part 5

Spring WS provides an easy integration with various WS-Security features with the help of interceptors like Wss4jSecurityInterceptor, XwsjSecurityInterceptor. We are going to explore here very basic feature of WS-SECURITY i.e. implementing Security using with UserNameTokenAuthentication We are going to use Wss4jSecurityInterceptor as it is very easy to configure. We are going to use configure two interceptors: 1) One for the Server End. 2) Other for the Client End. For Server End The configuration for Wss4jSecurityInterceptor is as follows: @Bean public Wss4jSecurityInterceptor wss4jSecurityInterceptor() { /** * The SecurementActions for UsernameToken is commented, as the * UsernameToken is to be added by the client, the server-side * interceptor would only validate that. * */ Wss4jSecurityInterceptor wss4jSecurityInterceptor = new Wss4jSecurityInterceptor(); wss4jSecurityInterceptor.setValidationActions("UsernameToken");

Spring WS - Part 4

Another interesting and essential feature is the attachment part. Now I found two things out here. The attachment can be inline within the SOAP message body (suitable as long as the attachment size is not too long) or we can enable MTOM feature within the marshaller and leverage the MTOM-XOP feature. For the attachment to be inline with the SOAP message body, no actual configuration are required, everything is being taken care by the Spring WS framework, except the following: &ltxs:element name="getCountryRequest"&gt &ltxs:complexType&gt &ltxs:sequence&gt &ltxs:element name="name" type="xs:string"/&gt &ltxs:element name="file" type="xs:base64Binary" xmime:expectedContentTypes="application/octet-stream"&gt&lt/xs:element&gt &lt/xs:sequence&gt &lt/xs:complexType&gt &lt/xs:e
