As indicated in my last post, I've been playing around with Project Lombok a little. One of the easier to absorb features is the @Getter/@Setter annotations, which removes the need to explicitly define getters and setters in your Java classes.
I use IntelliJ as my main IDE. However, when I started to use Lombok, I would get error messages from the IDE when viewing a Spring configuration file that used setter injection.
The answer to this problem was to simply install the lombok-intellij-plugin, which fixed the error rather nicely.
We'll setup the scenario withe simplest of objects that I can think of. If you now have the answer you're looking for (and you probably do), feel free to skip the example below:
public class Person {
private String name;
public Person() {}
public Person(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
A very simplisitc Spock specification that uses Spring testing to inject an instance of a Person:
@ContextConfiguration
class PersonSpec extends Specification {
@Autowired
Person person
def "has a name"() {
expect: person.name == 'Rudiger'
}
}
And the bean that is autowired in from PersonSpec-context.xml:
<bean id="rudiger" class="prystasj.lombok.plugin.example.Person">
<property name="name" value="Rudiger"/>
</bean>
Here the test passes and there is no "red" for errors in our IDE.
Now if we replace the getter and setter in the Person with annotations from Lombok:
public class Person {
@Getter @Setter
private String name;
public Person() {}
public Person(String name) {
this.name = name;
}
}
The tests still passes, but our IDE is showing us some red when viewing the Spring configuration file:
At this point, installing the lombok-intellij-plugin sends the error away.
