Coding Assistance for REST Development

Besides the common Web services support, IntelliJ IDEA provides the following facilities for developing RESTful Web services:

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.

REST Client Tool Window

Dedicated REST Client tool window supports:

  • Constituting URL addresses semiautomatically from the specified Deployment point and the @Path annotation.
  • Submitting requests to the server.
  • Displaying server responses in the Response tab.
  • Code integration between the Java code and the contents of the REST Client window controls.
