As I am a lazy programmer most of the time I dont implement toString and equals methods on my grails domain classes. I would like to say thanks to Groovy for helping me out and giving me a ready made recipe for this. Now I just need to annotate my class with ToString and EqualAndHashCode annotation it adds appropriate implementation of these methods for me. Now My domain class looks something like this.<\/p>\n
[java]
\n@ToString(includeNames = true, includeFields = true, excludes = ‘dateCreated,lastUpdated,metaClass’)
\n@EqualsAndHashCode
\nclass Item {
\n String name
\n Float price
\n boolean active = true
\n Date dateCreated
\n Date lastUpdated
\n}
\n[\/java]<\/p>\n
Before adding this annotation my domain class toString looks like this<\/p>\n
[java]
\nItem item = new Item(name: &quot;Chips&quot;, active: false, price: 15)
\nprintln &quot;To String output -: &quot; + item \/\/To String output -: com.intelligrape.myapp.Item : null
\n[\/java]<\/p>\n
Now I get the following output for Item object toString<\/p>\n
[java]
\nItem item = new Item(name: &quot;Chips&quot;, active: false, price: 15)
\nprintln &quot;To String output -: &quot; + item \/\/To String output -: com.intelligrape.myapp.Item(name:Chips, price:15.0, active:false)
\n[\/java]<\/p>\n
To get this annotation on all my domain classed I updated the template of grails domain classes so that whenever I do create-domain-class it give me the annotated domain classes<\/p>\n
[java]
\n@artifact.package@
\nimport groovy.transform.EqualsAndHashCode
\nimport groovy.transform.ToString<\/p>\n
@ToString(includeNames = true, includeFields = true, excludes = ‘dateCreated,lastUpdated,metaClass’)
\n@EqualsAndHashCode
\nclass @artifact.name@ {<\/p>\n
Date dateCreated
\n Date lastUpdated
\n}
\n[\/java]
\n<\/p>\n
