Code inspection and quick fixes

IntelliJ IDEA supports code inspections and suggests quick fixes in the following cases:

IssueDefault Quick Fix
Inconsistency between a method annotation and the method return type: a @GET annotated method returns void value.Change to String.
Resource methods errors.Remove @Path annotation.
Incorrect parameter type. Validation for parameters annotated with @QueryParam or @PathParam annotations.
@DefaultValue issues. 
@GET
public String get(@DefaultValue("33.5") @QueryParam("str") int str){
    return "Hello";
}
DefaultValue is marked red with the description "Can't convert to int".
Rest @Path and @PathParam annotations inspections.
Rest References resolve problems. References in @PathParam annotations are resolved to templates in @Path annotations
This method should have only one HTTP method designator. Example: 
@GET
@POST
public String get(){
    return "Hello";
}
@POST is marked red.
WADL configuration errors.

  • Constituting URL addresses semiautomatically from the specified Deployment point and the @Path annotation.
