Learn how to access cq:defined Object<\/strong> in Sling Model classes. Before answering this question, I want to make sure that you guys are using latest Sling Model dependency and AEM version 6.x. So let’s start-<\/p>\n

Q1. How will I get properties object in Sling Model Class?<\/strong><\/h5>\n

I think there is no need to get this properties object as you can directly inject the resource properties ( already described in my previous blog) but if you still want to do that then, you have to make two changes.<\/p>\n

First use adaptable as SlingHttpServletRequest.class<\/strong> as shown below-<\/p>\n

@Model(adaptables = {SlingHttpServletRequest.class})<\/pre>\n
Then you can directly inject properties as shown below-<\/p>\n
@Inject\r\nprivate ValueMap properties;<\/pre>\n
Q2. During the build time, I am getting a Maven build error as shown below-<\/strong><\/h5>\n
 Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project blog-bundle: Compilation failure: Compilation failure:\r\n[ERROR] \/D:\/accunity\/blog\/bundle\/src\/main\/java\/sling\/models\/CQDefinedObjectImplModel.java:[3,34] package com.day.cq.commons.inherit does not exist\r\n[ERROR] \/D:\/accunity\/blog\/bundle\/src\/main\/java\/sling\/models\/CQDefinedObjectImplModel.java:[31,13] cannot find symbol\r\n[ERROR] symbol:   class InheritanceValueMap\r\n[ERROR] location: class sling.models.CQDefinedObjectImplModel\r\n[ERROR] \/D:\/accunity\/blog\/bundle\/src\/main\/java\/sling\/models\/CQDefinedObjectImplModel.java:[39,33] cannot access com.day.cq.commons.LabeledResource\r\n[ERROR] class file for com.day.cq.commons.LabeledResource not found\r\n[ERROR] -> [Help 1]\r\n[ERROR]\r\n[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.\r\n[ERROR] Re-run Maven using the -X switch to enable full debug logging.\r\n[ERROR]\r\n[ERROR] For more information about the errors and possible solutions, please read the following articles:\r\n[ERROR] [Help 1] http:\/\/cwiki.apache.org\/confluence\/display\/MAVEN\/MojoFailureException\r\n[ERROR]\r\n[ERROR] After correcting the problems, you can resume the build with the command\r\n[ERROR]   mvn <goals> -rf :blog-bundle<\/pre>\n
How to resolve this issue?<\/strong><\/h5>\n
For resolving this issue, \u00a0you need to add one more maven dependency into your project the dependency name is
\ncq–<\/strong>commens\u00a0and it’s Maven dependency is-<\/p>\n
<dependency>\r\n   <groupId>com.day.cq<\/groupId>\r\n   <artifactId>cq-commons<\/artifactId>\r\n   <version>5.5.0<\/version>\r\n   <scope>provided<\/scope>\r\n<\/dependency><\/pre>\n
Q3. How will I get inherited page properties object in Sling Model class?<\/strong><\/h5>\n
For getting this object in your Sling Model class, you need to inject a field as shown below-<\/p>\n
@Inject\r\nprivate InheritanceValueMap pageProperties;<\/pre>\n
With SlingHttpServletRequest.class <\/strong>as an\u00a0adaptable value.<\/p>\n
Q4. Can I use Resouce.class as well as slingHttpServletRequest.class as adaptable in the same\u00a0<\/strong>class?
\n<\/strong><\/h5>\n
Yes, you can do that. Here is the syntax-<\/p>\n
@Model(adaptables = {SlingHttpServletRequest.class,Resource.class})<\/pre>\n
Q5. How will I get page object in Sling Model class?<\/strong><\/h5>\n
For getting this object in your Sling Model class, you need to inject a field as shown below-<\/p>\n
@Inject\r\nprivate Page resourcePage;<\/pre>\n
With SlingHttpServletRequest.class <\/strong>as an\u00a0adaptable value.<\/p>\n
Q6. Do you have any working Sling model class example that implements all these properties?
\n<\/strong><\/h5>\n
Yes, here it is-<\/p>\n
@Model(adaptables = {SlingHttpServletRequest.class,Resource.class})\r\npublic class CQDefinedObjectImplModel {\r\n\r\n    private Logger logger = LoggerFactory.getLogger(CQDefinedObjectImplModel.class);\r\n\r\n    @Inject @Default(values = \"Ankur Chauhan\")\r\n    private String firstName;\r\n\r\n    private String value;\r\n\r\n    @Inject\r\n    private Page resourcePage;\r\n\r\n    @Inject\r\n    private InheritanceValueMap pageProperties;\r\n\r\n    @Inject\r\n    private ValueMap properties;\r\n\r\n    @PostConstruct\r\n    public void activate() {\r\n\r\n        logger.info(resourcePage.getPath()+\" ================= \");\r\n        String[] cloudServices = pageProperties.getInherited(\"cq:cloudserviceconfigs\",new String[0]);\r\n        logger.info(cloudServices.length + \" = lenght of array\");\r\n        for (String x : cloudServices) {\r\n            logger.info(\"Configuration is = \" + x);\r\n        }\r\n        firstName = properties.get(\"firstName\",\"\");\r\n        logger.info(firstName);\r\n    }\r\n\r\n    public String getValue() {\r\n        return \"Hi! \"+firstName;\r\n    }\r\n}<\/pre>\n
Q7. How am I testing these annotations in Sling Model class?<\/strong><\/h5>\n
I have created a dummy component and that component calls these Sling Model classes. Sightly code snippet is-<\/p>\n
\n
\n
<div data-sly-use.serviceResolver=\"sling.models.CQDefinedObjectImplModel\">\r\n    ${serviceResolver.value}\r\n<\/div><\/pre>\n
For complete working code, I am sharing the Git repository link.
\nhttps:\/\/bitbucket.org\/argildx\/accunity-blog-snippets\/src\/master\/<\/a><\/p>\n<\/div>\n<\/div>\n
Happy Coding!<\/p>\n
