This sample demonstrates how you can send an HTTP request to a Spring Integration HTTP service while utilizing Spring Integration's HTTP Path usage. This sample also uses Spring Security for HTTP Basic authentication. With the HTTP Path facility, the client program can send requests with URL Variables.

The sample consists of two parts:

  • Client and
  • Server

The Client program is provided as a JUnit test:

  • RestHttpClientTest

This test-case can be used to test the HTTP Path usage. It uses Spring's RestTemplate to assemble and send HTTP requests. The Server, on the other hand, is using Spring Integration's HTTP Endpoint configuration. The provided project itself is a web project and you can build the project using Gradle and deploy the resulting war under target/rest-http-*.war to Servlet Containers such as Jetty or Apache Tomcat:

$ gradlew :rest-http:build

To run this sample

  1. Deploy the project
  • If you are using Spring Tool Suite (STS) and project is imported as Eclipse project in your workspace you can just execute 'Run on Server'
  • You can also run gradlew :rest-http:build and generate the WAR file that you can deploy to Servlet Containers
  1. Run the simple JUnit Test:
  • You may change the URI Variable value in the test to see different results.

For example, when you give 0 as the URL Variable's value in the test, then you should see the following output from the server:

14:01:34,337  INFO main rest.RestHttpClientTest:95 - The employee list size :2
14:01:34,353  INFO main rest.RestHttpClientTest:101 - <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

14:01:34,556  INFO main rest.RestHttpClientTest:121 - Return Status :[0]
14:01:34,556  INFO main rest.RestHttpClientTest:122 - Return Status Message :[Success]


If you like to access the server's REST API yourself, please use the following URLs:

Return All Employees


Return Specific Employees


For example using cURL you can list the details for a specific user with:

$ curl -u SPRING:spring http://localhost:8080/rest-http/services/employee/1/search

This should produce output similar to this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><EmployeeList><Employee><employeeId>1</employeeId><fname>John</fname><lname>Doe</lname></Employee><returnStatus>0</returnStatus><returnStatusMsg>Success</returnStatusMsg></EmployeeList>


The REST Endpoint is using Spring Security. The security credentials are:

  • Username: SPRING
  • Password: spring

They are stored in src/main/resources/
