DSpace UI Prototype Challenge: Spring Boot + Thymeleaf
Download as PPT, PDF3 likes1,436 views
The document outlines a prototype application using Spring Boot and Thymeleaf, focusing on its configuration and features such as templating and security. It details the integration of various technologies and the use of Thymeleaf attributes for dynamic content generation. The prototype is currently limited in functionality, lacking item editing capabilities and full integration with DSpace's authentication system.

- 2. Technologies used âą Spring Boot â Newer, but built on Spring MVC âą See Cinecaâs prototype for MVC overview â Convention over configuration âą Prepackaged Maven / Gradle plugins â Embeddable Tomcat/Jetty (in JAR) â Autoconfiguration of Spring âą No requirement for XML configs â Autoconfiguration of many templating engines (Thymeleaf being one)
- 3. Technologies used âą Thymeleaf â Java/HTML5 templating engine â Looks like HTML (mostly) â Natural templating (view static HTML) â Supports HTML âfragmentsâ â FORCES separating content from layout â Spring specific integrations âą Bootstrap
- 4. Technologies used âą DSpace 6 (pre-6) Java API â With Enhanced Configuration Scheme (local.cfg / Apache Commons Config) âą Provides auto-reloadable configs âą Spring Security (AutnN/Z) â Used test âin memoryâ authN â AuthZ lets you limit access via Path â Very easy to use with Spring Boot
- 5. Spring Boot âą Configured to build a runnable JAR (embedded Tomcat) âą Enabled Thymeleaf plugin âą Enabled Spring Security plugin âą Spring Boot Application configuration â Application class â application.properties
- 6. Thymeleaf âą Looks like HTML, with âth:â attributes â th:fragment => th:include, th:replace â th:text (replace text) â th:if / th:unless â th:each (loop Lists/Iterable/Map/array) â th:with (sets a local variable) â th:href (dynamically build links)
- 7. Thymeleaf âą Looks like HTML, with âth:â attributes â th:fragment => th:include, th:replace â th:text (replace text / adds i18n) â th:if / th:unless â th:each (loop Lists/Iterable/Map/array) â th:with (sets a local variable) â th:href (dynamically build links) âą (Very) basic Java calls supported
- 8. Thymeleaf âą Also some special expressions / syntax: â ${variable} => output value of variable â #{i18n.key} => output i18n msg â @{path} => output a link/URL âą And Java utility objects: â #lists.isEmpty(java.util.List) â #arrays â #dates (formatting java.util.Date objs)
- 9. Prototype Theming âą Basic at this point â /static/themes directory â Themes consist of a layout.html and CSS, images, JS âą Custom code in DSpaceController â Allows one to customize theme loaded based on paths (in local.cfg)
- 10. Theming with Thymeleaf âą layout.html â Contains all our theme âfragmentsâ â (could split these into separate files, e.g. header.html, footer.hml) âą Thymeleaf can select fragments â by name â by DOM selects (e.g. #id selects an HTML tag by âidâ)
- 11. AuthN/AuthZ âą Spring Security â Not yet integrated with DSpaceâs Auth âą AuthN is using Spring Securityâs âtest modeâ (in memory auth) âą AuthN/Z Defined entirely in WebSecurityConfig âą Only one restricted path (/admin)
- 12. Demo
- 13. Prototype code / docs âą https://github.com/tdonohue/DSpac e-Spring-Boot â See README for documentation
- 14. Limits of Prototype âą No actual item editing/creation â Concentrated more on testing Thymeleaf extendability âą Spring Security AuthN/Z not integrated with DSpaceâs
